Description

Background Technology

[0001] This application claims priority to U.S. Provisional Application No. 63 / 073,229, filed September 1, 2020, the contents of which form the basis of this invention and are incorporated herein by reference in their entirety. Background Technology

[0003] This invention relates to glass articles for vehicle interior systems, and more particularly to glass articles configured to meet head impact testing requirements.

[0004] The carrier inlay includes curved surfaces, and a display can be incorporated into such curved surfaces. Materials used to form such curved surfaces are typically limited to polymers, which do not exhibit the same durability and optical properties as glass. Therefore, curved glass substrates are desirable, especially when used as covers for displays. Existing methods for forming such curved glass substrates, such as thermoforming, have drawbacks including high cost, optical distortion, and surface imprinting. Therefore, the applicant recognizes the need for a carrier inlay system that can incorporate curved glass substrates in a cost-effective manner without the problems typically associated with glass thermoforming processes.

[0022] Various embodiments of a glass object configured for improved head-on impact testing will now be described in detail, examples of which are illustrated in the accompanying drawings. The glass object described herein comprises a glass sheet adhered to a support member, and is configured to be connected to a vehicle internal system using one or more mounting elements. As will be described below, the glass object is configured for improved head-on impact testing based on balancing the Young's modulus and yield strength of the support member and mounting elements. Specifically, the Young's modulus and yield strength are selected to prevent glass sheet breakage (preventing deflection or reaching the maximum principal stress limit), while also decelerating the head in a manner that ensures the maximum force is continuously no greater than 80g for a duration greater than 3 ms. The embodiments described herein are provided with reference to illustration and not by means of limitation.

[0023] Generally, vehicle interior systems can include a variety of curved or flat surfaces, such as display surfaces. Forming such vehicle surfaces from glass materials offers several advantages over the typical curved plastic panels conventionally found in vehicle interiors. For example, glass is often considered to provide enhanced functionality and user experience in many covering applications, such as display and touchscreen applications, compared to plastic covering materials.

[0024] Figure 1 The illustration depicts an exemplary interior 10 of a vehicle, comprising three different embodiments of vehicle interior systems 20, 30, and 40. Vehicle interior system 20 includes a base, illustrated as a center console base 22, wherein a curved surface 24 includes a display 26. Vehicle interior system 30 includes a base, illustrated as an instrument panel base 32, wherein a curved surface 34 includes a display 36. The instrument panel base 32 typically includes, and may also include, an instrument panel 38 with a display. Vehicle interior system 40 includes a base, illustrated as a steering wheel base 42, wherein the steering wheel base has a curved surface 44 and a display 46. In one or more embodiments, the vehicle interior system includes a base that is an armrest, pillar, seat back, floor, headrest, door panel, or any part thereof that includes a curved surface within the vehicle interior.

[0025] The embodiments of the glass components described herein can be used in each of the vehicle interior systems 20, 30, and 40, plus other considerations. In some embodiments, the glass components discussed herein may include a cover glass sheet that also covers non-display surfaces of the dashboard, center console, steering wheel, door panels, etc. In such embodiments, the glass material may be selected based on its weight, decorative appearance, etc., and may be provided with a coating (e.g., an ink or pigment coating) including patterns (e.g., painted metallic, wood grain, leather, colored, etc.) to visually match the glass components with adjacent non-glass components. In certain embodiments, such ink or pigment coatings may have a level of transparency that provides a gap or color-matching functionality when displays 26, 36, 38, and 46 are not in operation. Additionally, although... Figure 1 The vehicle interior is described as a vehicle in the form of a car (e.g., a sedan, truck, bus, and the like), but the glass objects disclosed herein may be incorporated into other vehicles, such as trains, ships (vessels, ships, submarines, and the like) and spacecraft (e.g., remote-controlled aircraft, airplanes, jet aircraft, helicopters, and the like).

[0026] In the implementation, the curved surfaces 24, 34, and 44 can be any of a variety of curved shapes, such as those respectively in... Figure 2A and Figure 2B The V-shape or C-shape shown in the drawing. First refer to... Figure 2A The diagram shows a side view of an embodiment of a V-shaped glass object 50. The glass object 50 includes a glass sheet 52 having a first main surface 54, a second main surface 56 opposite to the first main surface 54, and a secondary surface 58 joining the first main surface 54 to the second main surface 56. The first main surface 54 and the second main surface 56 define the thickness T of the glass sheet 52. In this embodiment, the thickness T of the glass sheet 52 is 0.3 mm to 2 mm, specifically 0.5 mm to 1.1 mm. In a vehicle, the first main surface 54 faces the passengers of the vehicle.

[0027] In an embodiment, the first main surface 54 and / or the second main surface 56 include one or more surface treatments. Examples of surface treatments that can be applied to one or both of the first main surface 54 and the second main surface 56 include at least one of the following: an anti-glare coating, an anti-reflective coating, a coating that provides touch functionality, a decorative (e.g., ink or pigment) coating, or an easy-to-clean coating.

[0028] like Figure 2AAs can be seen, the glass sheet 52 has a curved region 60 disposed between the first flat section 62a and the second flat section 62b. In an embodiment, the curved region 60 has a radius of curvature R ranging from 20 mm to a radius of curvature smaller than that of a substantially flat or planar surface (e.g., R = 10 mm). Additionally, as... Figure 2A As illustrated, the curved region 60 defines a concave curve with respect to the first main surface 54, but in other embodiments, the curved region 60 is instead a convex curve with respect to the first main surface 54.

[0029] exist Figure 2A In the glass object 50, the second main surface 56 of the glass sheet 52 is adhered to the support member 64. In one embodiment, the glass sheet 52 is attached to the support member 64 via an adhesive layer 66. In another embodiment, the adhesive layer 66 bonding the support member 64 to the glass sheet 52 is a structural adhesive, such as a tough epoxy resin, a flexible epoxy resin, an acrylate, a silicone, a polyurethane resin, a polyurethane, a pressure-sensitive adhesive, or a silane-modified polymer. In another embodiment, the adhesive layer 66 has a thickness of 2 mm or less between the support member 64 and the glass sheet 52. Furthermore, the support member 64 includes a first support surface 68 and a second support surface 70 opposite to the first support surface 68, and the glass object 50 includes one or more mounting elements 72 connected to the second support surface 70.

[0030] like Figure 2A As illustrated, the glass object 50 may also include one or more display units 73. In one embodiment, the display unit 73 is located in the flat sections 62a, 62b. In other embodiments, the display unit 73 may be bent and positioned above the bending region 60. In one embodiment, the display unit 73 is bonded to the second main surface 56 of the glass sheet 52 using, for example, an optically clear adhesive. Additionally, in one embodiment, the support member 64 may include one or more apertures sized to accommodate the size and thickness of the display unit 73; otherwise, the display unit 73 may be disposed between the glass sheet 52 and the support member 64. In one embodiment, each display unit 73 is at least one of the following, including any necessary backlight unit: a light-emitting diode (LED) display, an organic LED (OLED) display, a microLED (microLED) display, a plasma display, a liquid crystal display (LCD), or an organic LCD (OLCD).

[0031] Figure 2B Depicting glass object 50, and detailing another embodiment of C-shaped glass object 50. (And...) Figure 2A Compared to the V-shaped glass object 50, Figure 2B The C-shaped glass object 50 has a larger curved region 60 and shorter flat sections 62a, 62b. V-shape and C-shape are merely two examples of curved glass objects 50 that can be produced according to the invention. In other embodiments, the glass object 50 may include a curved region 60 with opposing curvatures to produce an S-shape, a curved region 60 following a flat section 62a to produce a J-shape, and a curved region 60 separated by a flat section 62a to produce a U-shape, plus others. Additionally, as will be illustrated with respect to the embodiments discussed below, the glass object 50 may be flat.

[0032] In such Figure 2A and Figure 2B In the embodiment illustrated, the glass sheet 52 is formed in such a way that the bending region 60 is not permanent. That is, the glass sheet 52 is elastically deformed and springs back to a flat, non-bent (i.e., flat) configuration without adhering to the rigid support member 64. Thus, the glass sheet 52 is stressed to produce curvature and remains stressed throughout the life of the glass article 50. In embodiments where the glass article 50 is bent, such glass articles 50 can be formed using cold forming techniques. Generally, cold forming involves applying a bending force to the glass sheet 52 simultaneously on a process chuck having a bending-forming surface, and bending the glass sheet 52 to conform to the bending-forming surface. Subsequently, the first support surface 68 of the support member 64 adheres to the second main surface 56 of the glass sheet 52. In one embodiment, the adhesive layer 66 connecting the support member 64 to the glass sheet 52 is allowed to cure on a process chuck, or in other embodiments, the support member 64 is clamped to the glass sheet 52 such that the adhesive layer 66 can be detached (i.e., removed from the process chuck) for curing. The mounting element 72 can be engaged with the support member 64 before or after it is adhered to the glass sheet 52.

[0033] Advantageously, the surface treatment can be easily applied to the flat glass sheet 52 before bending occurs in the glass sheet 52, and cold forming allows the treated glass sheet 52 to be bent without damaging the surface treatment (as opposed to the high-temperature trend associated with thermoforming techniques, which require the surface treatment to be applied to bent objects in more complex processes). In embodiments, the cold forming process is performed at a temperature below the softening temperature of the glass sheet 52. Specifically, the cold forming process can be performed at room temperature (e.g., about 20°C) or slightly higher temperatures, such as 200°C or below, 150°C or below, 100°C or below, or 50°C or below.

[0034] See now for the description Figure 3A and Figure 3B 50 glass objects in the middle. Figure 3B Depicting Figure 3A An exploded view of a glass object. (e.g.) Figure 3A and Figure 3B As can be seen, glass object 50 is flat (i.e., uncurved), but the discussion of glass object 50 also applies to curved glass objects 50 (such as...). Figure 2A and Figure 2B (As shown in the illustration). Depicted in Figure 3A and Figure 3B The perspective view also helps to explain some of the functions associated with the support component 64 and the mounting element 72. Specifically, the mounting element 72 is configured to accommodate vehicle interior bases (such as center console base 22, instrument panel base 32, and / or steering wheel base 42, as...). Figure 1 (As shown in the illustration) meshing. Additionally, for example... Figure 2A and Figure 2B The curved glass object 50 illustrated here has a first support surface 68 of the support member 64 that is bent and holds the glass sheet 52 in its curved shape (at least in the curved region 60). Furthermore, the support member 64 and mounting element 72 are configured to provide sufficient bending stiffness to support the glass sheet 52 during headform impact testing (HIT). Therefore, Figure 3A and Figure 3B It also depicts a head type 74, which will be used to perform HIT. The glass object 50 is configured to meet the requirements of HIT as defined in standards such as FMVSS 201 of North America; ECE R21 of the European Union; and GB 11552 2009 of China.

[0035] Specifically, to meet the HIT requirements according to the above reference standards, the glass object 50 (which in this embodiment has a weight of 15 pounds and a diameter of 6.5 inches) needs to decelerate the head shape in such a way that it continuously resists a force of 80g for more than 3ms, while also preventing the glass sheet 52 from breaking. Breakage can be caused in two ways. First, the glass sheet 52 can be deflected sufficiently to cause shattering. Therefore, in this embodiment, the deflection (or intrusion) is maintained at 50mm or less. Second, the maximum principal stress on the glass sheet 52 can be increased above the yield strength of the glass sheet 52, thereby causing the glass sheet 52 to break. In this embodiment, the maximum principal stress is maintained below 800MPa. Generally, the two largest contributing factors to HIT performance are the support member 64 and the mounting element 72. That is, the support member 64 and the mounting element 72 can be designed to provide the necessary properties for a given glass sheet 52 to pass HIT, while the adhesive layer 66 makes a small contribution to HIT based on Young's modulus or yield strength.

[0036] As will be described in this article, HIT performance can be partially predicted from the bending stiffness of each component, and HIT performance can be determined according to the following Equation 1:

[0037]

[0038] Where D is the bending stiffness, E is the Young's modulus of the material, T is the thickness, and v is the Pascal's ratio of the material. In this regard, bending stiffness relates to rigidity, and the rigidity of the glass object 50 can be varied by changing the material properties and / or geometry of the support member 64 and the mounting element 72. The formula related to bending stiffness is given by the following Equation 2:

[0039]

[0040] Where K is rigidity, D is bending stiffness, w is the width of the glass object, l is the length of the glass object, and v is Pascal's ratio. From Equations 1 and 2, it can be seen that the geometric dimensions of the glass object 50 (i.e., the selection of width w, length l, and thickness T) and the material properties (i.e., Young's modulus) have a substantial effect on bending stiffness and rigidity. Generally, the width and length will be specified through specific applications and customer specifications, thus making the thickness (D∝T)... 3 The Young's modulus E is manipulated like a variable to achieve the required stiffness and bending stiffness for HIT performance.

[0041] By further considering the yield strength of each component, the design possibilities of the glass object 50 are further enhanced. Specifically, considering the yield strength of the support member 64 and the mounting element 72 allows for the consideration of the maximum elastic response of the support member 64 and the mounting element 72 during HIT.

[0042] For improved HIT performance, the specific structure and shape of the support component 64 and mounting element 72 are not as important as the overall rigidity, bending stiffness, and yield strength of each component. As mentioned above, shape can be largely specified by specific aesthetic design requirements, and rigidity and bending stiffness requirements are addressed by material selection as discussed below. For example, in the description of... Figure 3A and Figure 3BIn one embodiment, the support member 64 is a backplate. The rigidity or bending stiffness of this support member 64 can be varied, for example, by changing the material properties (i.e., Young's modulus and / or yield strength) or by changing the thickness. For a given material, such as an aluminum alloy backplate, the rigidity can be varied, for example, by changing the thickness of the backplate. Specifically, increasing the thickness will increase the rigidity. Additionally, for a given backplate thickness, the rigidity can be varied, for example, by changing the material used to manufacture the backplate. Specifically, the rigidity of the support member 64 will increase as the elastic modulus or yield strength of the material used to manufacture the support member 64 increases (e.g., a steel support member 64 will have higher rigidity than an aluminum support member 64 with the same geometry). In one embodiment, the support member 64 is made of metal, plastic, or a composite material. Additionally, in one embodiment, the support member 64 is in the form of a backplate, border frame, or window pane or grid structure. In one embodiment, the support member 64 is made of a material and designed in a way that the support member provides a rigidity of at least 100 N / mm.

[0043] In addition, in the description Figure 3A and Figure 3B In one embodiment, one or more mounting elements 72 include multiple, specifically four mounting brackets 76. Each mounting bracket 76 is U-shaped, having a first arm 78, a second arm 80, and a crossbeam 82 connecting the first arm 78 and the second arm 80. The first arm 78 is fastened (fastened, welded, adhered, interlocked, fitted, etc.) to a second support surface 70 of the support member 64, and the second arm 80 is configured to attach to a vehicle interior base (such as a center console base 22, an instrument panel base 32, and / or a steering wheel base 42, etc.). Figure 1 (As illustrated in the figure). In this embodiment, the rigidity of the mounting element 72 can be adjusted by changing the thickness of the arms 78, 80 and the crossbeam 82, or by changing the material (i.e., Young's modulus or yield strength) of the bracket 76, the number of brackets 76, the position of the brackets 76, or the shape of the brackets 76. In other embodiments, the mounting element 72 can be any of a variety of other suitable structures and can be made of any of a variety of metal alloys, plastics, composite materials, or a combination of one or more materials.

[0044] In view of the foregoing, the simulation is for those illustrated in the figure. Figure 3A and Figure 3B The various glass objects 50 in the structure are used for simulation, where Young's modulus and yield strength vary depending on the materials of the support member 64 and the mounting element 72. For the simulation, the components have the properties shown in Table 1 below.

[0045] Table 1. Properties of components involved in HIT performance simulation

[0046]

[0047] Figures 4A to 4C The HIT performance factor is modeled based on the yield strength (x-axis) and Young's modulus (y-axis) of the support component 64. For each simulation, the glass object 50 is modeled as a steel mounting element 72 with a rigidity of approximately 1200 N / mm. Figure 4A Describe the intrusion of the glass sheet based on its yield strength and Young's modulus. As previously mentioned, the intrusion should be kept below 50 mm. Figure 4A The diagram shows that Young's modulus of approximately 35 GPa and above tends to maintain an indentation of 50 mm or less. Additionally, yield strengths greater than approximately 125 MPa tend to maintain an indentation of 50 mm or less. Therefore, the design window for indentation is the region outside the intersection of the yield strength > 125 MPa and Young's modulus > 35 GPa.

[0048] Figure 4B The HIT performance factor describes the maximum continuous force during the 3ms deceleration period of the head shape. As previously mentioned, the maximum force above 3ms should be 80g or less. Figure 4B As an example, without constraints on Young's modulus (with respect to the scale depicted), the maximum force can be kept below 80g when the yield strength is less than about 250MPa. Figure 4B It is also demonstrated that, without constraints on yield strength (regarding the scale depicted), the maximum force can be maintained below 80g when the Young's modulus is less than approximately 35 GPa. Therefore, the design window for the maximum force continuously above 3 ms during deceleration is the region within the graph, extending to the yield strength < 250 MPa and the Young's modulus < 35 GPa.

[0049] Figure 4C The HIT (Hyperturbation Intensity) performance factor characterizes the maximum principal stress on the glass sheet. As previously mentioned, the maximum principal stress on the glass sheet should be kept below 800 MPa. Figure 4C In the figure, when the Young's modulus is higher than about 35 GPa, the maximum principal stress usually remains below 800 MPa.

[0050] Used in Figures 4A to 4C The information generated in the process, glass object 50 (such as Figure 3A and Figure 3B The HIT performance (illustrated in the figure) is simulated for support member 64 with various combinations of Young's modulus (E1) and yield strength (Y1). Figure 5The simulation results depicting the combination of Young's modulus and yield strength passing through the HIT are plotted as circles, while the combination of Young's modulus and yield strength not passing through the HIT is plotted as X. The shaded area between the two curves f1 and f2 represents the design window based on the Young's modulus (in GPa) and yield strength (in MPa) of the support member 64 that will pass through the HIT (excluding glass breakage).

[0051] Curves f1 and f2 are given by the following equations:

[0052] f1:E1=471.288*exp(-0.0294*Y1)+10; (39≤Y1≤520)

[0053] f2:E1=1.941e5*exp(-0.0336*Y1)+48; (223≤Y1≤520)

[0054] When the yield strength and Young's modulus of the support member 64 are on or above curve f1 and on or below curve f2, the glass object 50 including the support member 64 configured accordingly should have acceptable HIT performance. The shaded area shows a first star representing an exemplary embodiment of the aluminum alloy support member 64 and a second star representing an exemplary embodiment of the magnesium alloy support member 64.

[0055] A similar analysis is performed on mounted component 72. In detail, Figures 6A to 6C The HIT performance factor is modeled based on the yield strength (x-axis) and Young's modulus (y-axis) of the mounting element 72. For the simulation, the glass object 50 is modeled as an aluminum alloy support component 64 with a rigidity of approximately 320 N / mm. Figure 6A The intrusion of the glass sheet is described based on its yield strength and Young's modulus. Furthermore, the intrusion should be kept below 50 mm. Figure 6A The illustration shows that Young's modulus of approximately 20 GPa and above tends to maintain an intrusion of 50 mm or less. Figure 6A It is also described that the effect of Young's modulus decreases between approximately 200 MPa and 400 MPa. Therefore, when Young's modulus is greater than approximately 20 GPa and the design window for Young's modulus opens wider as the yield strength increases from 200 MPa to 400 MPa, the design window based on intrusion is substantially open at any yield strength (within the described scale).

[0056] Figure 6B Describe the HIT performance factor for the maximum force during the continuous 3ms deceleration period of the head shape. Furthermore, the maximum force exceeding 3ms should be 80g or less. Figure 6B As an example, without constraints on Young's modulus (at least regarding the scale depicted), the maximum force can be kept below 80g when the yield strength is less than about 150MPa. Figure 6BIt is also demonstrated that, without constraints on yield strength (at least regarding the scale depicted), the maximum force can be kept below 80g when the Young's modulus is less than about 85 GPa. Therefore, the design window for the maximum force during deceleration above 3 ms is the region within the graph, extending to the yield strength <150 MPa and the Young's modulus <85 GPa.

[0057] Figure 6C Describe the HIT performance factor for the maximum principal stress on the glass sheet. Furthermore, the maximum principal stress on the glass sheet should be kept below 800 MPa. Figure 6C In the graphs, without constraints on yield strength (at least within the depicted scale), the maximum principal stress typically remains below 800 MPa when the Young's modulus is below approximately 50 GPa. Furthermore, without constraints on Young's modulus (at least within the depicted scale), the maximum principal stress typically remains below 800 MPa when the yield strength is below approximately 275 MPa.

[0058] Used in Figures 6A to 6C The information generated in the process, glass object 50 (such as Figure 3A and Figure 3B The HIT performance (as illustrated in the figure) is simulated for mounting element 72 with various combinations of Young's modulus (E2) and yield strength (Y2). Figure 7 The simulation results depict the combination of Young's modulus and yield strength passing through the HIT using a circle, and the combination of Young's modulus and yield strength not passing through the HIT using an x-axis. The shaded area between the two curves f3 and f4 represents the design window based on the Young's modulus (in GPa) and yield strength (in MPa) of the mounting element 72 passing through the HIT.

[0059] Curves f3 and f4 are given by the following equations:

[0060] f3:E2=605.1203*exp(-0.0303*Y2)+3.9; (10≤Y2≤950)

[0061] f4:E2=765.0928*exp(-0.0094*Y2)+85; (78≤Y2≤950)

[0062] When the yield strength and Young's modulus of the mounting element 72 are on or above curve f3 and on or below curve f4, the glass object 50 configured to include the mounting element 72 should therefore have HIT performance. The shaded areas represent an exemplary embodiment of the steel mounting element 72 (first star), an exemplary embodiment of the magnesium alloy mounting element (second star), and an exemplary embodiment of the aluminum alloy mounting element 72 (third star).

[0063] since Figure 5 and Figure 7 Certain observations can be made. Specifically, when the yield strength of the support member 64 is increased, the relative stiffness increases, which reduces the maximum intrusion of the head shape and increases the deceleration of the head shape. The maximum principal stress on the glass sheet 52 changes only to a limited extent in response to the increase in the yield strength of the support member 64. Specifically, when the Young's modulus of the support member is increased, the relative stiffness increases, which reduces the maximum intrusion of the head shape and increases the deceleration of the head shape. Also, the maximum principal stress on the glass sheet 52 decreases. Regarding the mounting element 72, when the yield strength is increased, the relative stiffness increases, which reduces the maximum intrusion of the head shape and increases the deceleration of the head shape. In addition, the maximum principal stress on the glass sheet increases. When the Young's modulus of the mounting element 72 is increased, the relative stiffness increases, which reduces the maximum intrusion of the head shape and increases the deceleration of the head shape. The maximum principal stress on the glass sheet 52 increases again.

[0064] Additionally, self-drawn illustrations are shown below. Figure 5 and Figure 7 The design window in the middle is used to draw the overall design window of HIT performance. Figure 8 Specifically, this refers to designs where the deceleration is continuously no greater than 80g for 3ms and the maximum principal stress is less than 800MPa. For example... Figure 8 As can be seen, the design window is drawn based on the rigidity of the mounting element 72 (i.e., the mounting bracket 76 implemented in the model) and the supporting component 64. Figure 8 In this context, the first curve 84 considers the HIT performance without regard to the contribution of yield strength to the HIT response of the glass object 50. Specifically, the first curve 84 below is generated by the design based on the following Equation 3, which is based on a maximum effective stiffness (K2) of 270 N / mm:

[0065]

[0066] Wherein K1 and K2 represent the rigidity of the support components and mounting elements. By further considering the contribution of the yield strength as described herein, the design window exceeding 270 N / mm effective rigidity is widened to the second curve 86. That is, by taking into account the elastic limit of the deformation of the support component 64 and mounting element 72, the design window through HIT (excluding glass breakage) is extended to the region below curve 86 to allow for greater design flexibility.

[0067] The following paragraphs provide various geometric, mechanical, and strengthening properties of glass sheet 52 and composites of glass sheets. See also Figure 9Additional structural details of the glass sheet 52 are illustrated and described. As mentioned above, the glass sheet 52 has a thickness T, which is substantially constant and defined as the distance between the first main surface 54 and the second main surface 56. In various embodiments, T may refer to the average thickness or maximum thickness of the glass sheet. Furthermore, the glass sheet 52 includes: a width W, defined as a first maximum dimension of either the first main surface 54 or the second main surface 56 orthogonal to the thickness T; and a length L, defined as a second maximum dimension of either the first main surface 54 or the second main surface 56 orthogonal to both the thickness and the width. In other embodiments, W and L may be the average width and average length of the glass sheet 52, respectively.

[0068] In various embodiments, the average or maximum thickness T is in the range of 0.3 mm to 2 mm. In various embodiments, the width W is in the range of 5 cm to 250 cm, and the length L is in the range of about 5 cm to about 1500 cm. As mentioned above, the radius of curvature of the glass sheet 52 (e.g., as...) Figure 2A and Figure 2B The R shown in the figure is approximately 30 mm to approximately 1000 mm.

[0069] In one or more embodiments, the glass sheet 52 may be strengthened. In one or more embodiments, the glass sheet 52 may be strengthened to include compressive stress extending from a surface to the depth of compression (DOC). The compressive stress zone is balanced by a central portion exhibiting tensile stress. At the DOC, the stress transitions from positive (compressive) stress to negative (tensile) stress.

[0070] In various embodiments, the glass sheet 52 can be mechanically strengthened by utilizing the mismatch in the coefficients of thermal expansion between several parts of the object to create compressive stress zones and a central region exhibiting tensile stress. In some embodiments, the glass sheet can be thermally strengthened by heating the glass to a temperature above the glass transition point and then rapidly quenching it.

[0071] In various embodiments, the glass sheet 52 can be chemically strengthened by ion exchange. In the ion exchange process, ions at or near the surface of the glass sheet are replaced by or exchanged with larger ions having the same valence or oxidation state. In other embodiments where the glass sheet comprises alkali aluminosilicate glass, the ions and larger ions in the surface layer of the object are monovalent alkali metal cations, such as Li. + Na + K + 、Rb + and Cs + Alternatively, the monovalent cations in the surface layer can react with monovalent ions other than alkali metal cations, such as Ag. +Or a similar alternative. In such embodiments, the monovalent ions (or cations) exchanged into the glass sheet generate stress.

[0072] Ion exchange processes are typically carried out by immersing a glass sheet in a molten salt bath (or two or more salt baths) containing larger ions to exchange with smaller ions in the glass sheet. It should be noted that aqueous salt baths can also be used. Furthermore, the bath complex can include one or more types of larger ions (e.g., Na+ and K+) or a single larger ion. Those skilled in the art will understand that parameters of the ion exchange process, including but not limited to the bath complex and temperature, immersion time, number of immersions of the glass sheet in the salt bath, use of multiple salt baths, and additional steps such as annealing, cleaning, and the like, are generally determined by the glass sheet complex (including the structure of the object and any crystalline phases present) and the desired DOC and CS of the self-strengthening glass sheet. Illustrative molten bath complexes may include nitrates, sulfates, and chlorides of larger alkali metal ions. Typical nitrates include KNO3, NaNO3, LiNO3, NaSO4, and combinations thereof. Depending on the glass sheet thickness, bath temperature, and glass (or monovalent ion) diffusivity, the temperature of the molten salt bath typically ranges from about 380°C to about 450°C, while the immersion time ranges from about 15 minutes to about 100 hours. However, temperatures and immersion times different from those described above may also be used.

[0073] In one or more embodiments, the glass sheet 52 may be immersed in a molten salt bath of 100% NaNO3, 100% KNO3, or a combination of NaNO3 and KNO3 at a temperature of about 370°C to about 480°C. In some embodiments, the glass sheet may be immersed in a molten mixed salt bath comprising from about 5% to about 90% KNO3 and from about 10% to about 95% NaNO3. In one or more embodiments, the glass sheet may be immersed in a first bath followed by immersion in a second bath. The first and second baths may have different compositions and / or temperatures than each other. The immersion times in the first and second baths may vary. For example, the immersion in the first bath may be longer than the immersion in the second bath.

[0074] In one or more embodiments, the glass sheet may be immersed in a molten mixed salt bath having a temperature of less than about 420°C (e.g., about 400°C or about 380°C) for a time of less than about 5 hours or even about 4 hours or less. The molten mixed salt bath comprises NaNO3 and KNO3 (e.g., 49% / 51%, 50% / 50%, 51% / 49%).

[0075] Ion exchange conditions can be tailored to provide a “spiking” or increase the slant of the stress profile at or near the surface of the resulting glass sheet. Spikes can lead to larger surface CS values. Due to the unique properties of the glass composites used in the glass sheets described herein, this spike can be achieved through a single bath or multiple baths, wherein the baths contain a single composite or a mixture of composites.

[0076] In one or more embodiments where monovalent ions are exchanged into a glass sheet, different monovalent ions can be exchanged to different depths within the glass sheet (and generate different amounts of stress within the glass sheet at different depths). The resulting relative depths of stress-generating ions can be determined, and this leads to different characteristics of the stress profile.

[0077] CS is measured using known components of this art, such as commercially available instruments, such as the FSM-6000 manufactured by Orihara Industrial Co., Ltd. (Japan), via a surface stress meter (FSM). Surface stress measurement relies on the accurate measurement of the stress optical coefficient (SOC), which is related to the birefringence of the glass. SOC is measured using methods known of this art, such as the fiber and four-point bending method and the bulk cylindrical method, both of which are described in ASTM standard C770-98 (2013) entitled “Standard Test Method for Measurement of Glass Stress-Optical Coefficient,” the entire contents of which are incorporated herein by reference. As used herein, CS may refer to “maximum compressive stress,” which is the highest compressive stress value measured within the compressive stress layer. In some embodiments, the maximum compressive stress is located at the surface of the glass sheet. In other embodiments, the maximum compressive stress may occur at a depth below the surface, thereby providing a compressive profile for the “embedded peak” appearance.

[0078] Depending on the strengthening method and conditions, DOC can be measured using an ion exchange microscopy (FSM) or a scattered light polariscope (SCALP) (such as the SCALP-04 scattered light polariscope available from Glassstress Ltd. in Tallinn Estonia). When glass sheets are chemically strengthened by ion exchange treatment, the FSM or SCALP is used depending on which ion is exchanged into the glass sheet. Where stress in the glass sheet is generated by the exchange of potassium ions into the glass sheet, the FSM is used to measure DOC. Where stress is generated by the exchange of sodium ions into the glass sheet, the SCALP is used to measure DOC. Where stress in the glass sheet is generated by the exchange of both potassium and sodium ions into the glass, since the exchange depth of sodium ions indicates DOC and the exchange depth of potassium ions indicates the change in the magnitude of compressive stress (but not the change in stress from compression to tension), the exchange depth of potassium ions in such glass sheets is measured using an FSM. Central tension, or CT, is the maximum tensile stress and is measured using a SCALP.

[0079] In one or more embodiments, the glass sheet may be strengthened to exhibit a DOC (as described herein) as a fraction of the thickness T of the glass sheet. For example, in one or more embodiments, the DOC may range from about 0.05T to about 0.25T. In some individual examples, the DOC may range from about 20 μm to about 300 μm. In one or more embodiments, the strengthened glass sheet 52 may have a CS (which may be found at the surface or at a depth within the glass sheet) of about 200 MPa or more, about 500 MPa or more, or about 1050 MPa or more. In one or more embodiments, the strengthened glass sheet may have a maximum tensile stress or central tension (CT) in the range of about 20 MPa to about 100 MPa.
