Description

[Technical field]

[0001] The present disclosure relates to laminates and methods of making laminates. More specifically, the disclosed examples relate to decorative laminates. [Background technology]

[0002] Decorative laminates are used in a variety of applications, including wall surfaces, countertops, and other structures such as aircraft interior structural components. For example, decorative laminates may be applied to surfaces of aircraft interior structural components, such as cabin interior sidewall and ceiling panels, floor panels, storage bins, toilet and galley panels and structures, bulkheads, window shades, and other aircraft interior structural components.

[0003] During the course of normal use, people may come into contact with the aircraft's interior surfaces and transfer traces of bacteria or other microorganisms to the decorative laminate. Additionally, luggage, food, non-sterile air, etc. may transfer traces of microorganisms or substances that promote the growth of microorganisms. Inhibiting such growth and / or eliminating such microorganisms is desirable to improve cleanliness and prevent the spread of microorganisms. Some antimicrobial paints have been used for this purpose, but are aesthetically and functionally limited and may obscure design elements when applied to the decorative laminate. Graphics or intricate patterns applied with paint may lack durability, be difficult and / or expensive to manufacture. Summary of the Invention [Means for solving the problem]

[0004] The present disclosure provides systems, devices, and methods for antimicrobial decorative laminates. In some examples, the decorative laminate can include a first laminate layer and a second laminate layer that contain an antimicrobial agent. The decorative layer can be selectively disposed between the first laminate layer and the second laminate layer. The first and second laminate layers can include a thermoplastic fluoropolymer material. The first laminate layer, the decorative layer, and the second laminate layer can be laminated together to form a decorative laminate, and the laminate can be configured for attachment to a structural component.

[0005] In some examples, the decorative laminate system can include a structural component having a joining surface and a decorative laminate affixed to the joining surface. The decorative laminate can include a first laminate layer of a permeable appearance containing an antimicrobial agent and a second laminate layer of an opaque appearance. The first and second laminate layers can include a thermoplastic fluoropolymer material, and the decorative layer can be disposed between the first and second laminate layers. The decorative laminate can further include a resin layer disposed on the second laminate layer and an adhesive layer disposed between the joining surface of the decorative laminate and the structural component.

[0006] In some examples, the vehicle can include a structural component and a decorative laminate affixed to the structural component. The decorative laminate can include a first laminate layer containing an antimicrobial agent, a second laminate layer, and a decorative layer disposed between the first and second laminate layers. The first and second laminate layers can include a thermoplastic fluoropolymer material. The first laminate layer, the decorative layer, and the second laminate layer can be laminated together to form the decorative laminate.

[0007] The features, functions, and advantages may be achieved independently in various examples of the present disclosure or may be combined in yet other examples, the details of which can be understood with reference to the following description and drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Various aspects and examples of antimicrobial decorative laminates are described below and illustrated in the associated drawings. Unless otherwise specified, decorative laminates and / or various components thereof according to the present teachings may include, but are not limited to, at least one of the structures, parts, functions and / or variations described, illustrated and / or included herein. Furthermore, unless specifically excluded, the process steps, structures, components, functions and / or variations described, illustrated and / or included herein in connection with the present teachings may be included in other similar devices and methods, including interchangeable among the disclosed examples. The following description of various examples is merely exemplary in nature and is not intended to limit the disclosure, its applications or uses in any way. Furthermore, the advantages provided by the examples and examples described below are exemplary in nature, and not all examples and examples provide the same advantages or to the same extent.

[0010] This detailed description includes the following sections, which follow immediately below: (1) Overview; (2) Examples, Components, and Alternatives; (3) Advantages, Features, and Features; and (4) Conclusion. The Examples, Components, and Alternatives section is further divided into subsections A through G, with each subsection labeled accordingly.

[0011] overview In general, the antimicrobial decorative laminate may include a decorative layer selectively disposed between an inner layer containing an antimicrobial material and an outer layer. The outer layer may be transparent and the inner layer may be translucent or opaque. The decorative layer may include visible and / or light activated materials arranged in a decorative and / or functional pattern. The laminate may be configured for attachment to a structure or structural component. Figure 1 is a schematic diagram of an exemplary antimicrobial decorative laminate 10 attached to a structure 28.

[0012] The decorative laminate 10 includes a first layer 62a, a decorative layer 76, and a second layer 62b. The decorative layer 76 is selectively disposed between the first layer 62a and the second layer 62b. As shown in FIG. 1, selectively disposed may be understood to mean that the decorative layer 76 is disposed between the first layer 62a and the second layer 62b in some portions of the decorative laminate 10 and is not disposed between the first layer 62a and the second layer 62b in other portions of the decorative laminate. The first layer 62a, the decorative layer 76, and the second layer 62b may be laminated together to form the decorative laminate 10.

[0013] The decorative layer 76 may include ink, pigment, or other visible material. For example, the decorative layer may be an ink pattern printed on the second layer 62b. The decorative layer may additionally or alternatively include a light-activated material, as described in U.S. Pat. No. 9,718,302, which is incorporated by reference in its entirety for all purposes. For example, the decorative layer may include an ultraviolet (UV) activated pigment that is invisible until exposed to a UV light source. The decorative layer may be arranged in a decorative and / or functional pattern. For example, the layer may include a manufacturer's logo, a bar code, and / or an alignment pattern that facilitates alignment of the decorative laminate 10 during application to the structure 28.

[0014] The second layer 62b includes a thermoplastic fluoropolymer material. In particular, the second layer can be a polyvinylidene fluoride film, an integral color polyvinyl fluoride film, and / or a polyvinyl fluoride film adhered to an aluminum foil. The second layer can be opaque.

[0015] The first layer 62a has a first side 64a and a second side 64b. The first side 64a can be described as facing away from the structure 28 upon application of the decorative laminate 10 to the structure. The second side 64b can be in contact with, touch and / or face the decorative layer 76. The first layer 62a can be optically transparent, allowing the decorative layer 76 to be visible. The first layer 62a can also be transparent to ultraviolet (UV) and / or infrared (IR) light, such light incident on the first layer passing through the decorative layer 76 and affecting the light-activated material.

[0016] The first layer 62a includes a thermoplastic fluoropolymer material 74 and an antimicrobial agent 81. The antimicrobial agent may include any effective chemical, biological, and / or combination of agents, including, but not limited to, bacteriostatic, fungistatic, antibiotic, and bactericidal agents. For example, the antimicrobial agent may be a metal, such as silver, copper, zirconium, sodium, potassium, and / or any combination thereof. As another example, the antimicrobial agent may be a phenol, such as para-tert-amylphenol (PTAP).

[0017] The antimicrobial agent 81 and the thermoplastic fluoropolymer material 74 of the first layer 62a can be encapsulated, bonded, cohesive or otherwise combined in any effective manner to form the first layer. The antimicrobial agent can be uniformly distributed throughout the polymeric material, localized proximate to the first surface 64a of the first layer, and / or arranged according to a pattern. The antimicrobial agent can be distributed according to the effect of the manufacturing process. In the illustrated example, the antimicrobial agent 81 is dispersed in the thermoplastic fluoropolymer material 74 in a higher concentration toward the first surface 64a of the first layer 62a. Such a distribution can provide the desired antimicrobial effect while minimizing the required amount of the antimicrobial agent 81.

[0018] The antimicrobial agent 81 and the polymeric material can be combined in such a way as to achieve a desired degree of transparency for the first layer 62a. For example, the metal agent can be micronized to minimize visual defects. In one particular contemplated example, the antimicrobial agent can include a metal powder having a median particle size of approximately 1 micrometer, 1 nanometer, or other size scale that minimizes the visibility of the powder or provides some other desired characteristic.

[0019] The first layer 62a can be a metal polymer nanocomposite (MPN). Powdered metal such as silver can be co-precipitated with a thermoplastic fluoropolymer such as polyvinylidene fluoride to achieve a particulate polymer composite. By selecting the loading percentage and microstructural characteristics such as size, size distribution and inter-cluster separation, the desired light transmission, UV transmission and / or IR transmission can be provided. The first layer 62a can include a particulate or dispersoid polymer composite with powdered metal on either the micro- or macro-scale.

[0020] The antimicrobial agent 81 can be disposed on the first surface 64a of the first layer 62a. For example, a dissolved phenolic compound can be uniformly coated onto the first layer. Or, a powdered metal suspended in a transparent ink can be printed onto the first layer 62a in a grid pattern that provides an effective antimicrobial coating while maintaining a desired degree of transparency of the first layer 62a.

[0021] The antimicrobial agent 81 may be combined with the polymeric material prior to lamination of the first layer to form the first layer 62a to form the decorative laminate 10. The antimicrobial agent 81 may be combined with the polymeric material of the first layer 62a following lamination of the first layer to form the decorative laminate 10.

[0022] The decorative laminate 10 can further include additional layers disposed between the first layer and the decorative layer, between the decorative layer and the second layer, and / or between the second layer and the structure. The additional layers can include, for example, one or more of a resin layer, a polymer laminate layer, a decorative layer, and / or an adhesive layer.

[0023] The first layer 62a can be described as the outermost layer that is disposed the greatest distance from the structure 28 when the decorative laminate 10 is applied to the structure. The antimicrobial agent 81 can be disposed at and / or on the first surface 64a of the first layer 62a, which can be described as the outer surface of the decorative laminate 10. That is, when the decorative laminate 10 is applied to the structure 28, microorganisms that come into contact with the decorative laminate can come into contact with the first surface 64a of the first layer 62a and the antimicrobial agent 81.

[0024] A decorative laminate system can include a decorative laminate 10 and one or more structures 28. A vehicle can include a structure 28 and an attached decorative laminate 10. The decorative laminate 10 can be attached to any vehicle and / or building structure, structural component, and / or structural composite panel. For example, the decorative laminate can be attached to an interior structural component of an aircraft, rotorcraft, spacecraft, watercraft, automobile, or truck. The decorative laminate can also be attached to an interior structural component of a building, such as a bathroom counter, stall partition, floor, information sign, and / or door. In general, it may be desirable to apply an antimicrobial decorative laminate to a surface or structural component where microorganisms may be found.

[0025] 2 illustrates an exemplary cabin interior of an air vehicle 12 including structural components 28 coated with one or more examples of the antimicrobial decorative laminates disclosed herein, such as decorative laminate 10. Structural components 28 include cabin interior side walls 13 and ceiling panels 14, floor panels 15, storage bins 16, and window shades 17. Other structural components of the air vehicle 12 can be coated with an antimicrobial decorative laminate according to the present teachings, including, but not limited to, thermal barriers, moisture barriers, composite noise panels, toilet and galley panels and structures, bulkheads, and cargo bin liners.

[0026] Examples, components and alternatives The following sections describe selected aspects of exemplary antimicrobial decorative laminates and related systems and / or methods. The examples in these sections are for illustrative purposes and should not be construed as limiting the overall scope of the disclosure. Each section may include one or more separate embodiments or examples and / or contextual or related information, functionality and / or structures.

[0027] A. Exemplary Antimicrobial Decorative Laminates As shown in Figures 3A-3B, this section describes an exemplary decorative laminate 110. The decorative laminate 110 is one example of the antimicrobial decorative laminate 10 as described above. Figure 3A is an exploded side view of the decorative laminate 110, and Figure 3B is an assembled side view of the decorative laminate. As shown, the decorative laminate 110 includes a plurality of laminate layers 162, including at least a first laminate layer 162a and a second laminate layer 162b. Depending on the decorative laminate 110 to be manufactured, one or more additional laminate layers 162 can be included.

[0028] 3A, the first laminate layer 162a has a first side 164a and a second side 164b. The first laminate layer 162a has a transmissive appearance 168 or a transparent appearance in that it transmits light.

[0029] The laminate layer 162 may have a thickness ranging from about 0.25 mils to about 5.0 mils, although other suitable thicknesses may be used. The first laminate layer 162a may have a thickness ranging from about 1.0 mils to about 2.0 mils. Selecting a thickness within this range may promote a transparent appearance 168 of the first laminate layer 162a, thereby allowing one or more decorative images to be clearly displayed. The second laminate layer 162b and the additional laminate layer 162 may each have a thickness ranging from about 2.0 mils to about 4.0 mils. Selecting a thickness within this range may allow for the use of less expensive, more widely available laminate layers and may facilitate the ease of manufacturing of the decorative laminate.

[0030] In this example, the first laminate layer 162a is composed of a metal polymer nanocomposite (MPN) of silver and polyvinyl fluoride (PVF). Powdered silver nanoparticles 181 are uniformly dispersed throughout a thermoplastic fluoropolymer material 174, such as a polyvinyl fluoride (PVF) film. The nanoparticle concentration and / or fill ratio can be selected to maximize the antimicrobial properties of the first laminate layer 162a, while maintaining a desired degree of permeability.

[0031] In this example, the second laminate layer 162b is also composed of a thermoplastic fluoropolymer material 174. The thermoplastic fluoropolymer material 174 may include polyvinyl fluoride (PVF) film, polyvinylidene fluoride (PVDF) film, integral color polyvinyl fluoride (PVF) film, polyvinyl fluoride (PVF) film / aluminum foil / adhesive material, or another suitable thermoplastic fluoropolymer material.

[0032] A polyvinyl fluoride (PVF) film that may be used is commercially available from E. I. du Pont de Nemours and Company, Wilmington, Delaware, under the name TEDLAR (TEDLAR is a registered trademark of E. I. du Pont de Nemours and Company, Wilmington, Delaware. A polyvinylidene fluoride (PVDF) film that may be used is commercially available from Avery Dennison Company, Glendale, Calif., under the name AVIMARK (AVIMARK is a trademark of Avery Dennison Corporation, Glendale, Calif.).

[0033] The integral color polyvinyl fluoride (PVF) film is comprised of a polyvinyl fluoride (PVF) film with a decorative color incorporated into the PVF film. The polyvinyl fluoride (PVF) film / aluminum foil / adhesive material includes a PVF film having an opaque appearance 172 combined with 0.7 mil aluminum foil combined with an adhesive material.

[0034] Polyvinyl fluoride materials are advantageous for the laminate layer 162 due to their physical toughness, chemical inertness, abrasion resistance, and consistent performance despite temperature changes. Polyvinyl fluoride materials can also accommodate a wide variety of inks used in printing graphics. As used herein, the term "thermoplastic fluoropolymer material" refers to polyvinyl fluoride-based materials, including polyvinyl fluoride polymers (i.e., polymers formed from vinyl fluoride). Fluorinated polymers are generally polymers, copolymers, or terpolymers of vinyl fluoride.

[0035] The laminate layers 162, such as the second laminate layer 162b, may additionally or alternatively include non-polymeric materials. For example, a thermoplastic fluoropolymer material may be reinforced with fiberglass or carbon fiber. The second laminate layer 162b may include fiberglass reinforced plastic and / or woven fiberglass. Such reinforcement materials may be advantageous for use in high traffic areas.

[0036] 3A, the second laminate layer 162b has a first side 170a and a second side 170b. The second laminate layer 162b has an opaque appearance 172 or a non-transparent appearance in that it does not transmit light therethrough.

[0037] The decorative laminate 110 further includes a decorative layer 176 selectively disposed between the first laminate layer 162a and the second laminate layer 162b. When a layer is described as being "selectively disposed between" a layer or "disposed on" another layer, it will be understood by one of ordinary skill in the art that the layer may be formed directly on a layer or one or more intervening layers may be provided therebetween.

[0038] In this example, decorative layer 176 includes a decorative ink layer. Decorative layer 176 may include one or more of inkjet printing ink, silk screen printing ink, pigment-based ink, dye-based ink, paint, stain, digital printing ink, or another suitable material.

[0039] The decorative layer 176 includes a first side 178a and a second side 178b. The first side 178a of the decorative layer 176 is adjacent to the second side 164b of the first laminate layer 162a and the second side 178b of the decorative layer 176 is adjacent to the first side 170a of the second laminate layer 162b. The decorative layer 176 can have a thickness in the range of about 0.25 mils to about 5.0 mils, although other suitable thicknesses can be used.

[0040] The decorative layer 176 can be disposed or added between the first laminate layer 162a and the second laminate layer 162b. The decorative layer 176 can be printed on the second surface 164b of the first laminate layer 162a to form a printed decorative material surface 166. The decorative layer 176 can be disposed between the first laminate layer 162a and the second laminate layer 162b or printed on the first laminate layer 162a by a printing process. The printing process can include inkjet printing, silk screen printing, digital printing, or another suitable printing process.

[0041] The decorative laminate 110 further includes a resin layer 184 disposed on the second laminate layer 162b. As shown in FIG. 3A, the resin layer 184 has a first side 188a and a second side 188b. The first side 188a of the resin layer 184 is adjacent to the second side 170b of the second laminate layer 162b. The resin layer 184 may have a thickness ranging from about 0.25 mils to about 5.0 mils, although other suitable thicknesses may be used.

[0042] The resin layer 184 can be disposed between the decorative layer 176 and the second laminate layer 162b. That is, the first side 188a of the resin layer 184 can be adjacent to the second side 178b of the decorative layer 176, and the second side of the resin layer 184 can be adjacent to the first side 170a of the second laminate layer 162b. Such a series of layers can be used with the second laminate layer 162b including fiberglass, as described above.

[0043] The resin layer 184 may include an embossed resin layer, a prepreg resin layer, or another suitable resin material layer. The resin material of the resin layer 184 may be a texture-retaining material that forms the texture introduced during processing and maintains the texture after curing. The embossed resin layer 184 may include one or more thermosetting resin materials 186 of epoxy, polyester, phenolic, polyurethane, and / or combinations thereof. The thermosetting resin material 186 may provide texture support, retention, and adhesion to the laminate layer 162 adjacent to the thermosetting resin material 186 of the resin layer 184, particularly polyvinyl fluoride (PVF) films. The embossed resin layer 184 may be a colored embossable resin, such as a thermosetting resin material 186, which may be embossed to provide texture to the decorative laminate 110, and may be colored to match the color or predominant color of the image or design printed on the first laminate layer 162a or another laminate layer 162.

[0044] The decorative laminate 110 may further include an optional adhesive layer 190 disposed between the decorative laminate 110 and a mating surface 196 of a structural component 128, such as in the form of an internal structural component 128a. As shown in FIG. 3A, the adhesive layer 190 includes a first side 192a and a second side 192b. The first side 192a of the adhesive layer 190 is adjacent to the second side 188b of the resin layer 184, and the second side 192b of the adhesive layer 190 is adjacent to the mating surface 196. The adhesive layer 190 may have a thickness ranging from about 0.25 mils to about 5.0 mils, although other suitable thicknesses may be used.

[0045] The adhesive layer 190 can include a pressure sensitive adhesive 190a that can be applied to or integral with the decorative laminate 110. The pressure sensitive adhesive 190a can have a release liner 194 that can be removed and discarded when the decorative laminate 110 is applied to the structural component 128.

[0046] The adhesive layer 190 may include a spray adhesive, or other suitable spray or liquid adhesive material, which may be applied to the mating surface 196 of the structural component 128 when the decorative laminate 110 is applied to the structural component 128.

[0047] The first laminate layer 162a, the decorative layer 176 and the second laminate layer 162b together comprise the top portion 198a or top sheet. The top portion 198a together with the resin layer 184 can form the decorative laminate 110, which is flexible and can be easily formed around corners, contours or curved portions of structures such as the structural component 128.

[0048] The first laminate layer 162a, the decorative layer 176, the second laminate layer 162b and the resin layer 184 are configured to be laminated together in a stacked order to form the decorative laminate 110 and to be attached to a structural component 128. The structural component 128, such as the inner structural component 128a, has a joining surface 196.

[0049] When the decorative laminate 110 is applied to the structural component 128, the first laminate layer 162a can be the outermost. That is, people or objects that come into contact with the decorative laminate 110 can come into contact with the first surface 164a of the first laminate layer 162a. Microorganisms that are transferred to the laminate can be killed or inhibited from growing by the silver particles 181 or other antimicrobial agents in the first laminate layer 162a.

[0050] B. Exemplary Antimicrobial Decorative Laminates As shown in Figures 4A-4B, this section describes an exemplary decorative laminate 210. The decorative laminate 210 is another example of the antimicrobial decorative laminate 10 as described above. Figure 4A is an exploded side view of the decorative laminate 210, and Figure 4B is an assembled side view of the decorative laminate. As shown, the decorative laminate 210 includes a top portion 298a comprised of a first laminate layer 262a, a decorative layer 276, and a second laminate layer 262b. The decorative laminate 210 also includes a base portion 298b comprised of a third laminate layer 262c, i.e., a base layer, and a resin layer 284 disposed between the second laminate layer 262b and the third laminate layer 262c. The presence of the base portion 298b can create a more rigid decorative laminate 210, which is beneficial for application to flat or substantially flat surfaces.

[0051] The first laminate layer 262a, the decorative layer 276, the second laminate layer 262b, the resin layer 284 and the third laminate layer 262c are configured to be laminated together in a stacked order to form the decorative laminate 210 and to be attached to a structural component 228. The structural component 228 has a joining surface 296.

[0052] 4A, the first laminate layer 262a has a first side 264a, a second side 264b, and a transmissive or transparent appearance 268 in that it transmits light. The second laminate layer 262b has a first side 270a and a second side 270b.

[0053] 4A, the third laminate layer 262c includes a first side 275a and a second side 275b. When an adhesive layer 290 is included, the first side 275a of the third laminate layer 262c is adjacent to the second side 288b of the resin layer 284, and the second side 275b of the third laminate layer 262c is adjacent to the first side 292a of the adhesive layer 290. The third laminate layer 262c as well as the second laminate layer 262b may each have an opaque appearance 272 or a non-transparent appearance in that they do not transmit light therethrough.

[0054] In this example, the first laminate layer 262a is comprised of a permeable thermoplastic fluoropolymer material 274, such as a polyvinyl fluoride (PVF) film, and an antimicrobial coating 281 is disposed on the thermoplastic fluoropolymer material 274. The antimicrobial coating 281 thus comprises the first surface 264a of the first laminate layer 262a. The antimicrobial coating 281 may include a phenolic compound, such as para-tert-amylphenol (PTAP), and / or a solution thereof. Additionally, the antimicrobial coating is permeable and sufficiently heat and pressure resistant to withstand lamination without adverse effects.

[0055] The second laminate layer 262b and the third laminate layer 262c may each be comprised of a thermoplastic fluoropolymer material 274. As discussed above, the thermoplastic fluoropolymer material 274 may include polyvinyl fluoride (PVF) film, polyvinylidene fluoride (PVDF) film, integral color polyvinyl fluoride (PVF) film, polyvinyl fluoride (PVF) film / aluminum foil / adhesive material, or another suitable thermoplastic fluoropolymer material.

[0056] The decorative laminate 210 further includes a decorative layer 276 selectively disposed between the first laminate layer 262a and the second laminate layer 262b. The decorative layer 276 has a first side 278a and a second side 278b, where the first side 278a of the decorative layer 276 is adjacent to the second side 264b of the first laminate layer 262a and the second side 278b of the decorative layer 276 is adjacent to the first side 270a of the second laminate layer 262b.

[0057] The decorative layer 276 includes one or more opaque or visible materials selectively disposed between the first laminate layer 262a and the second laminate layer 262b. The decorative layer 276 can include one or more of inkjet printing inks, silk screen printing inks, pigment-based inks, dye-based inks, paints, stains, digital printing inks, or another suitable material.

[0058] The decorative layer 276 can be disposed or added between the first laminate layer 262a and the second laminate layer 262b. The decorative layer 276 can be printed onto the second surface 264b of the first laminate layer 262a to form a printed decorative material surface 266. The decorative layer 276 can be disposed between the first laminate layer 262a and the second laminate layer 262b or printed onto the first laminate layer 262a by a printing process, as described above for the decorative laminate 110.

[0059] The decorative laminate 210 further includes a resin layer 284 disposed on the second laminate layer 262b. As further shown in Figure 4A, the resin layer 284 has a first side 288a and a second side 288b. The first side 288a of the resin layer 284 is adjacent to the second side 270b of the second laminate layer 262b, and the second side 288b of the resin layer 284 is adjacent to the first side 275a of the third laminate layer 262c.

[0060] The resin layer 284 may include an embossed resin layer, a prepreg resin layer, or another suitable resin material layer. The embossed resin layer 284 may include one or more thermosetting resin materials 286, as described for the decorative laminate 110 above.

[0061] The decorative laminate 210 may further include an optional adhesive layer 290 disposed between the third laminate layer 262c and a mating surface 296 of the structural component 228. As shown in FIG. 4A, the adhesive layer 290 has a first side 292a and a second side 292b. The first side 292a of the adhesive layer 290 is adjacent to the second side 275b of the third laminate layer 262c, and the second side 292b of the adhesive layer 290 is adjacent to the mating surface 296. In this example, the adhesive layer 290 includes a spray adhesive layer 290b. However, other suitable spray or liquid adhesive materials may be used. Alternatively, the adhesive layer 290 may include a pressure sensitive adhesive 290a that may be applied to or integrated with the decorative laminate 210.

[0062] C. Exemplary Antimicrobial Decorative Laminates Using Light-Activated Materials As shown in Figures 5A-5B, this section describes an exemplary decorative laminate 310. The decorative laminate 310 is another example of the antimicrobial decorative laminate 10 described above. Figure 5A is an exploded side view of the decorative laminate 310, and Figure 5B is an assembled side view of the decorative laminate. As shown, the decorative laminate 310 includes a first laminate layer 362a, a decorative layer 376, a second laminate layer 362b, a third laminate layer 362c, and a resin layer 384.

[0063] The first laminate layer 362a, the decorative layer 376, the second laminate layer 362b, the third laminate layer 362c and the resin layer 384 are laminated together in a stacked order to form the decorative laminate 310 that is configured for attachment to a structural component 328. The structural component 328 has a joining surface 396.

[0064] In this example, as shown in Figures 5A-5B, the third laminate layer 362c and resin layer 384 of the decorative laminate 310 are in the reverse order compared to the decorative laminate 210 of Figures 4A-4B. As shown in Figures 5A-5B, the decorative laminate 310 includes a top portion 398a or top sheet made up of the first laminate layer 362a, the decorative layer 376, and the second laminate layer 362b, and a base portion 398b or base layer made up of the third laminate layer 362c and the resin layer 384.

[0065] As further shown in Figures 5A-5B, decorative laminate 310 has a third laminate layer 362c disposed between second laminate layer 362b and resin layer 384. Again, similar to decorative laminate 210 of Figures 4A-4B, the presence of base 398b can create a more rigid decorative laminate 310, which is beneficial for application to a flat or substantially flat surface.

[0066] 5A, the second laminate layer 362b has a first surface 370a and a second surface 370b. The third laminate layer 362c includes a first surface 375a and a second surface 375b. The first surface 375a of the third laminate layer 362c is adjacent to the second surface 370b of the second laminate layer 362b, and the second surface 375b of the third laminate layer 362c is adjacent to the first surface 388a of the resin layer 384.

[0067] The second laminate layer 362b and the third laminate layer 362c can each have an opaque appearance 372 or a non-transparent appearance in that they do not transmit light therethrough. Similar to the decorative laminate 210 of Figures 4A-4B above, the second laminate layer 362b and the third laminate layer 362c can each be comprised of a thermoplastic fluoropolymer material 374.

[0068] The second laminate layer 362b or the third laminate layer 362c can include a foil, such as an aluminum foil, adhered to a thermoplastic fluoropolymer material. For example, the second laminate layer 362b can include a layer of foil bonded to a thermoplastic fluoropolymer film, forming the second side 370b of the second laminate layer 362b. Thus, the foil can contact the first side 375a of the third laminate layer 362c.

[0069] As further shown in FIG. 5A, the first laminate layer 362a has a first side 364a, a second side 364b and a transmissive or transparent appearance in that it transmits light. In this example, the first laminate layer 362a is made of a permeable thermoplastic fluoropolymer material 374, such as a polyvinyl fluoride (PVF) film, and has an antimicrobial coating 381 on a first surface 364a. The antimicrobial coating 381 may include a finely powdered metal, such as silver, zinc, or copper, mixed with a permeable or non-visible ink material. The ink material and powdered metal may be printed onto the first surface 364a of the first laminate layer 362a to form a printed antimicrobial surface. The ink material and powdered metal may be printed uniformly on the first surface 364a and / or may be printed in a pattern, such as a grid. The printing process may include inkjet printing, silk screen printing, digital printing, or another suitable printing method.

[0070] The decorative laminate 310 further includes a decorative layer 376 selectively disposed between the first laminate layer 362a and the second laminate layer 362b. As shown in Figures 5A-5B, the decorative layer 376 includes a first side 378a and a second side 378b, where the first side 378a of the decorative layer 376 is adjacent to the second side 364b of the first laminate layer 362a and the second side 378b of the decorative layer 376 is adjacent to the first side 370a of the second laminate layer 362b.

[0071] The decorative layer 376 includes one or more visible materials 380 selectively disposed between the first laminate layer 362a and the second laminate layer 362b. The one or more visible materials 380 may include one or more of visible inkjet printing inks, visible silk screen printing inks, visible pigment-based inks, visible dye-based inks, visible paints, visible stains, visible digital printing inks, or another suitable visible material.

[0072] The decorative layer further includes one or more non-visible light activated materials 382 selectively disposed between the first laminate layer 362a and the second laminate layer 362b. The one or more non-visible light activated materials 382 can change from a non-visible state to a visible state upon exposure to a light source 412. The light source 412 can be an ultraviolet (UV) light source, an infrared (IR) light source, a light emitting diode (LED) light source, or another suitable light source.

[0073] The one or more non-visible light-activated materials 382 may include one or more of a non-visible inkjet printing ink, a non-visible silk screen printing ink, a non-visible pigment-based ink, a non-visible paint, a non-visible stain, a non-visible digital printing ink, or another suitable non-visible light-activated material, each configured to change from a non-visible state to a visible state upon exposure to the light source 412. For example, the non-visible light-activated material 382 may include a light-activated or light-sensitive material, such as a UV-sensitive non-visible or invisible ink. UV-sensitive non-visible or invisible ink is a class of ink that is non-visible to the naked eye, but is highly visible under ultraviolet light.

[0074] The decorative layer 376 can be disposed or added between the first laminate layer 362a and the second laminate layer 362b. The decorative layer 376 can be printed on the second surface 164b of the first laminate layer 162a to form a printed decorative material surface 366. The decorative layer 376 can be disposed between the first laminate layer 362a and the second laminate layer 362b or printed on the first laminate layer 362a by a printing method. The printing process can include inkjet printing, silk screen printing, digital printing, or another suitable printing method.

[0075] The decorative laminate 310 further includes a resin layer 384 disposed on the third laminate layer 362c. As further shown in FIG. 5A, the resin layer 384 has a first side 388a and a second side 388b. The first side 388a of the resin layer 384 is adjacent to the second side 375b of the third laminate layer 362c, and the second side 388b of the resin layer 384 is adjacent to a first side 392a of the adhesive layer 390. The resin layer 384 includes a prepreg resin layer.

[0076] The decorative laminate 310 may further include an optional adhesive layer 390 disposed between the resin layer 384 and the mating surface 396 of the structural component 328. As shown in FIG. 5A, the adhesive layer 390 includes a first side 392a and a second side 392b. The first side 392a of the adhesive layer 390 is adjacent to the second side 388b of the resin layer 384, and the second side 392b of the adhesive layer 390 is adjacent to the mating surface 396. In this example, the adhesive layer 390 includes a spray adhesive layer. However, other suitable spray or liquid adhesive materials can be used. Alternatively, the adhesive layer 390 can include a pressure sensitive adhesive 390a that can be applied to or integrated with the decorative laminate 310.

[0077] D. Antimicrobial Structural Components and Composite Panels 6 is a front perspective view of assembled structural composite panels 328b, such as stiffened structural composite panels, each having an antimicrobial decorative laminate 310 as described above with a location system pattern 400. Each decorative laminate 310 has a top portion 398a and a base portion 398b.

[0078] Each decorative laminate 310 includes visible material 380, for example in the form of an arrow image, and includes non-visible light-activated material 382 in the form of a location system pattern 400. The non-visible light-activated material 382 forms a location system pattern 400, such as registration pattern 400a, on the decorative area 404 of each decorative laminate 310. The non-visible light-activated material 382 may be disposed or printed on the decorative laminate 310 in the registration pattern 400a to facilitate alignment and positioning of the decorative laminate 310 upon application to the structural component 328. Additionally, each decorative laminate 310 includes an antimicrobial agent in an antimicrobial coating 381, as previously described.

[0079] Non-decorative information or markings, such as manufacturing location targets 402a, 402b, made of invisible light activated material 382, ​​can be included in the location system pattern of each decorative laminate 310. Upon illumination with a light source, such as an ultraviolet (UV) light source, an infrared (IR) light source, or another suitable light source, the manufacturing location targets 402a, 402b provide a manufacturer, manufacturing related user, or other user with a visible target reference point for positioning and aligning the decorative laminate 310 on the structural composite panel 328b. Additionally, the manufacturing location targets 402a, 402b remain intact and are not cut away from the final manufacturing version of the decorative laminate 310 that has been applied to the structural composite panel 328b.

[0080] Non-decorative information or markings, such as assembly location targets 402c made of invisible light activated material 382, ​​can be included in the location system pattern of each decorative laminate 310. The assembly location targets 402c along the registration seams 406 are formed between the two decorative laminates 310 of each of the two structural composite panels 328b to facilitate alignment and positioning of the decorative laminates 310 and the structural composite panels 328b relative to one another.

[0081] When illuminated by a light source, such as an ultraviolet (UV) light source, an infrared (IR) light source, or another suitable light source, the assembly location targets 402c provide an assembler, assembly-related user, or other user with a visible target reference point for aligning the decorative laminate 310 on each structural composite panel 328b with respect to one another. Additionally, the assembly location targets 402c remain intact and are not cut away from the final manufactured or assembled version of the decorative laminate 310 that has been applied to the structural composite panel 328b.

[0082] In addition to the manufacturing location targets 402a, 402b and the assembly location target 402c, the non-visible light activated material 382 can be placed or printed on the decorative laminate 310 in the form of part numbers, bar codes, repair instructions or other non-decorative information to identify and verify structural components for inspection, repair, removal, maintenance or other procedures.

[0083] 7A-7B, Fig. 7A shows a front perspective view of structural component 328, where decorative laminate 310 shows a first theme 408, such as an image or design that is visible, e.g., the number "777," and a second theme 410, such as an image or design that is not visible, e.g., the sun and clouds. Fig. 7B shows a front perspective view of structural component 328 of Fig. 7A, where decorative laminate 310 shows a first theme 408, such as the number "777," that is visible, and a second theme 410, such as the sun and clouds, that is visible upon exposure to and illumination by light source 412.

[0084] The decorative laminate 310 has a top 398a, a base 398b, and a decorative region 404. The visible material 380 forms a first theme 408, e.g., the number "777," and the non-visible light activated material 382 forms a second theme 410, e.g., a sun and clouds. The second theme 410 can be separate and distinct from the first theme 408. Or, the second theme 410 can enhance the first theme 408, i.e., the second theme 410 can be part of, connected to, or accentuate the first theme 408 in some way. The top of the laminate 310 can include an antimicrobial coating 381 as described above and / or any antimicrobial agent, for example, dispersed or added as a layer on the top.

[0085] In Figure 7A, the first theme 408 of visible material 380 is visible and the second theme 410 of non-visible light activated material 382 is invisible and in an invisible state or condition. In Figure 7B, the first theme 408 of visible material 380 is visible and the second theme 410 of non-visible light activated material 382 is now visible due to illumination 414 from and exposure to a light source 412, such as in the form of an ultraviolet (UV) light source 412a. In Figure 7B, the second theme 410 has changed from an invisible state to a visible state (Figure 9B) due to exposure to the light source 412.

[0086] 7B, a lighting system 418, such as an aircraft lighting system, is coupled or connected to light sources 412 via a connection element 416, such as a wired or wireless connection. The light sources 412, such as an ultraviolet (UV) light source 412a, are configured to irradiate the non-visible light-activated material 382 causing it to change from a non-visible state to a visible state. The light sources 412 may also include an infrared (IR) light source, a light emitting diode (LED) light source, or another suitable light source.

[0087] E. Exemplary Methods of Making Antimicrobial Decorative Laminates In this section, exemplary method steps for making an antimicrobial decorative laminate are described. See FIG. 8. The decorative laminate, laminate layer and / or decorative layer aspects described above are applicable in the method steps described below. Where appropriate, references may be made to components and systems that may be used to perform each step. These references are for illustrative purposes and are not intended to limit the possible ways of performing a particular step of the method.

[0088] Figure 8 is a flow chart illustrating steps performed in an exemplary method. Various steps of method 500 are described below and illustrated in Figure 8, however, the steps need not all be performed and may possibly be performed simultaneously or in a different order than shown. Based on the present disclosure, it should be understood that additional steps may be performed without departing from the claims.

[0089] In step 502, the method includes disposing a decorative layer between a first laminate layer and a second laminate layer. The first and second laminate layers can each include a thermoplastic fluoropolymer material. The first laminate layer can be clear or transmissive and can further include an antimicrobial agent.

[0090] By incorporating the antimicrobial agent into the first laminate layer prior to manufacture of the decorative laminate, manufacturing of the decorative laminate can be simplified, allowing the use of well-tested procedures and existing equipment. Alternatively, the antimicrobial agent can be incorporated into the first laminate layer after manufacture of the decorative laminate. This sequence of method steps may be appropriate for temperature- or pressure-sensitive antimicrobial agents that may undergo undesirable chemical or physical changes during lamination.

[0091] Antimicrobial agents can include any effective chemical, biological, and / or combination of agents, including, but not limited to, bacteriostatic, fungistatic, antibiotic, and bactericidal agents. For example, the antimicrobial agent can be a metal, such as silver, copper, zirconium, sodium, potassium, and / or any combination thereof. In another example, the antimicrobial agent can be a phenol, such as para-tert-amylphenol (PTAP).

[0092] The antimicrobial agent and the thermoplastic fluoropolymer material of the first laminate layer can be incorporated, adhered, cohesive or otherwise combined in any effective manner. The antimicrobial agent can be uniformly distributed throughout the thermoplastic fluoropolymer material, can be localized adjacent to one side of the first laminate layer, and / or can be arranged according to some pattern. The antimicrobial agent and the polymeric material can be combined in such a way as to achieve the desired permeability of the first laminate layer.

[0093] The decorative layer may include one or more visible materials. The decorative layer may further include one or more non-visible light-activated materials that change from a non-visible state to a visible state upon exposure to a light source. The light source may be an ultraviolet (UV) light source, an infrared (IR) light source, or another suitable light source.

[0094] Step 502 may include disposing the decorative layer by a printing process, which may include inkjet printing, silk screen printing, digital printing, or another suitable printing method. Step 502 may further include disposing one or more non-visible light activated materials in a registration pattern to facilitate alignment of the completed laminate upon application to the cured structural composite panel.

[0095] The method 500 then includes adding a resin layer to the second laminate layer 504. The method 500 further includes forming a decorative laminate 506 by sequentially stacking the first laminate layer, the decorative layer, the second laminate layer and the resin layer and laminating them together at a specific heat and a specific pressure.

[0096] Step 506 can include using a press molding process to heat and cure the first laminate layer, the decorative layer, the second laminate layer, and the resin layer at a specific heat, such as an effective elevated temperature, at a specific pressure, such as an effective pressure, for a useful period of time to form a decorative laminate. The first laminate layer, the decorative layer, the second laminate layer, and the resin layer can be laminated in a large sheet, for example, 5 feet by 8 inches, over a flat configuration, such as a flat metal backing plate. The large sheet can be heated and cured in a multi-stage press with flat platens, such as used in the press molding process.

[0097] Effective elevated temperatures for heating and curing the decorative laminate can range from about 200° F. to about 400° F. or higher. Effective periods for heating and curing the decorative laminate can range from about 10 minutes to about 120 minutes or higher. Effective pressures for heating and curing the decorative laminate can be, for example, at pressures ranging from about 150 psi (50 pounds per square inch) to about 200 psi (200 pounds per square inch). The temperature, pressure and time selected for heating and curing can be selected based on the type of resin layer used to form the decorative laminate, such as a thermosetting resin or a thermoplastic resin, or the type of thermosetting resin or the type of thermoplastic resin used.

[0098] Large sheets of the stacked first laminate layer, decorative layer, second laminate layer, and resin layer can be heated and cured in a multi-stage press at pressures ranging from about 150 psi (50 pounds per square inch) to about 200 psi (200 pounds per square inch), at temperatures ranging from about 200°F (200°F) to about 400°F (400°F), for times ranging from about 10 minutes to about 120 minutes. For example, the heat cycle can have a duration of about 60 minutes, including ramp-up and ramp-down times, and can be maintained at maximum temperature for up to 20 minutes. The decorative laminate can be allowed to cool to ambient temperature in the multi-stage press for a sufficient period of time and then removed for application to a structural component, such as an interior structural component of an aircraft. The decorative laminate can also be formed by other known press forming processes.

[0099] Step 508 of the method includes curing the structural composite panel. Step 510 includes applying a decorative laminate to an interface surface of the cured structural composite panel with an adhesive layer. The adhesive layer may include a pressure sensitive adhesive with a release liner, a spray adhesive, or another suitable adhesive material. The cured structural composite panel may form a portion of a structural component. The structural component may be an interior structural component of an aircraft, rotorcraft, spacecraft, watercraft, automobile, truck, and / or other vehicle. Step 510 may further include applying the decorative laminate to one or more of a flat, curved, contoured, or another suitable surface of the structural component.

[0100] Method 500 further includes an optional step 512 of adding an additional laminate layer adjacent to either the first side or the second side of the resin layer. Step 512 can be repeated as necessary to add one or more additional laminate layers. Additionally, any flame retardant or other laminate material can be added to the decorative laminate. Additionally, the decorative laminate can be applied to the structural component 128 using known methods, such as thermoforming, vacuum forming, or another suitable known application method.
