Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 858,664, filed on June 7, 2019, the contents of which are relied upon and incorporated herein by reference in their entirety. Background Art

[0003] The present disclosure relates to glass articles and methods of forming the same, and more particularly, to vehicle interior systems including glass articles having a carrier having a coefficient of thermal expansion that closely matches that of a glass sheet.

[0004] Vehicle interiors include curved surfaces, and displays may be incorporated into these curved surfaces. The materials used to form these curved surfaces are typically limited to polymers, which do not exhibit the durability and optical performance of 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 disadvantages including high cost, optical distortion, and surface marking. Therefore, applicants have identified a need for a vehicle interior system that can incorporate curved glass substrates in a cost-effective manner and without the problems typically associated with glass thermoforming processes. Summary of the Invention

[0005] According to one aspect, embodiments of the present disclosure relate to a curved glass article. The curved glass article comprises a glass sheet having a first major surface and a second major surface. The second major surface is opposite the first major surface, and the first major surface and the second major surface define a thickness therebetween. The curved glass article further comprises a carrier having a curvature, and the carrier is made of a carrier material. The coefficient of thermal expansion (CTE) of the carrier material is 8 (10 -6 ) / ℃ to 40(10 -6 ) / ° C. The glass sheet is adhered to the carrier such that the glass sheet conforms to the curvature of the carrier.

[0006] According to another aspect, embodiments of the present disclosure relate to a curved glass article. The curved glass article comprises a glass sheet having a first major surface and a second major surface, the second major surface being opposite the first major surface. The first and second major surfaces define a thickness therebetween. The curved glass article also comprises a carrier having a curvature and an adhesive that bonds the second major surface of the glass sheet to the carrier so that the glass sheet conforms to the curvature of the carrier. The adhesive has a bond strength. A combined stress comprises a bending stress that causes the glass sheet to conform to the curvature and a shear stress caused by the differential expansion of the glass sheet and the carrier when heated from room temperature to 75°C. The combined stress is less than the bond strength.

[0025] Reference will now be made in detail to various embodiments, examples of which are illustrated in the accompanying drawings. Generally, various embodiments relate to vehicle interior systems having curved glass surfaces. In the embodiments discussed herein, the curved glass surface comprises a glass sheet bonded to a carrier that holds the glass in its curved shape. Furthermore, the carrier is configured to mount to the frame of the vehicle interior system. Advantageously, the carrier defines a border (i.e., a non-display area) having a width of at most approximately 10 mm, more particularly, a width of at most approximately 2 mm, thereby allowing the majority of the glass surface to be used for viewing a display mounted thereon. The carrier can be so small and have such a small border width because the stress between the cold-bent glass and the carrier is optimized, significantly reducing the likelihood of the glass sheet peeling from the carrier. In particular, the coefficient of thermal expansion (CTE) of the carrier matches the CTE of the glass, so that the thermal stress component of the total stress between the glass sheet and the carrier does not cause the glass sheet to shear the adhesive bonding the glass sheet to the carrier. Various embodiments of the carrier and various configurations for mounting the carrier to a vehicle frame are disclosed herein. These embodiments are provided by way of illustration only and are not intended to be limiting.

[0026] Typically, vehicle interior systems may include a variety of different curved surfaces designed to be transparent, such as curved display surfaces and curved non-display glass covers. Forming curved vehicle surfaces from glass materials offers numerous advantages over the typical curved plastic panels commonly found in vehicle interiors. For example, glass is generally considered to provide enhanced functionality and user experience in many curved cover material applications, such as display applications and touchscreen applications, compared to plastic cover materials.

[0027] Figure 1 An exemplary vehicle interior 1000 is shown, including three different embodiments 100, 200, and 300 of vehicle interior systems. Vehicle interior system 100 includes a frame, shown as a center console base 110, having a curved surface 120 containing an optically bonded display 130. Vehicle interior system 200 includes a frame, shown as an instrument panel base 210, having a curved surface 220 containing an optically bonded display 230. Instrument panel base 210 typically includes an instrument panel 215, which may also include an optically bonded display. Vehicle interior system 300 includes a frame, shown as a steering wheel base 310, having a curved surface 320 and an optically bonded display 330. In one or more embodiments, the vehicle interior system includes a frame that is an armrest, pillar, seat back, floor, headrest, door panel, or any portion of the vehicle interior that includes a curved surface. In other embodiments, the frame is part of a housing for a freestanding display (i.e., a display that is not permanently attached to a part of the vehicle). In an embodiment, the optically bonded display 130, 230, 330 is at least one of a light emitting diode (LED) display, an organic LED (OLED) display, a liquid crystal display (LCD), or a plasma display.

[0028] Embodiments of the glass articles described herein can be used in each of the vehicle interior systems 100 , 200 , and 300 . Furthermore, the glass articles discussed herein can be used as curved cover glass for any of the display embodiments discussed herein, including displays used in the vehicle interior systems 100 , 200 , and / or 300 . Furthermore, in various embodiments, various non-display components of the vehicle interior systems 100 , 200 , and 300 can be formed from the glass articles discussed herein. In some such embodiments, the glass articles discussed herein can be used as non-display cover surfaces for instrument panels, center consoles, door panels, and the like. In these embodiments, the glass material can be selected based on its weight, aesthetic appearance, and the like, and can be provided with a coating (e.g., an ink or pigment coating) having a pattern (e.g., a brushed metal look, a wood grain look, a leather look, a tinted look, etc.) to visually match the glass component with adjacent non-glass components. In certain embodiments, these ink or pigment coatings can have a level of transparency that provides a deadfront or color-matching function.

[0029] In an embodiment, the curved surface 120, 220, 320 is generally as follows Figures 2A-2B V-shaped as shown or Figures 3A-3B First refer to the C type shown. Figure 2A , which shows a side view of an embodiment of a V-shaped glass article 10. The V-shaped glass article 10 includes a glass sheet 12. The glass sheet 12 has a first major surface 14 and a second major surface 16. In a vehicle, the first major surface 14 faces the vehicle's occupants, and the second major surface 16 is the rear surface of the V-shaped glass article 10, to which a display (e.g., an LED display, an OLED display, an LCD display, or a plasma display) can be mounted (e.g., using an optically clear adhesive). The second major surface 16 is opposite the first major surface 14, and the first and second major surfaces 14, 16 define a thickness T of the glass sheet 12. The first and second major surfaces 14, 16 are joined by a minor surface 18.

[0030] As in Figure 2A As can be seen in FIG, the glass sheet 12 has a curved region 20 disposed between the first flat portion 22a and the second flat portion 22b. In an embodiment, the curved region 20 has a radius of curvature R ranging from 20 mm to 10 m. Figure 2A As shown, the curved region 20 defines a concave curve, but in other embodiments, the curved region 20 is an alternative convex curve. Figure 2A In the V-shaped article 10, adhesive 24 is applied to the second major surface 16 in the bend region 20. The adhesive 24 connects the carrier 26 to the glass sheet 12.

[0031] In an embodiment, adhesive 24 comprises a pressure sensitive adhesive. Exemplary pressure sensitive adhesives suitable for adhesive 24 include 3M TM VHB TM (available from 3M Company, St. Paul, Minnesota) or tesa (available from tesa SE, Norderstedt, Germany). In an embodiment, the adhesive 24 comprises a liquid adhesive. Exemplary liquid adhesives include toughened epoxies, flexible epoxies, acrylics, silicones, urethanes, polyurethanes, and silane-modified polymers. In a particular embodiment, the liquid adhesive comprises one or more toughened epoxies, such as EP21TDCHT-LO (available from Masterbond, Hackensack, New Jersey), 3M TM Scotch-Weld TM Epoxy DP460 off-white (available from 3M Company, St. Paul, Minnesota). In other embodiments, the liquid adhesive comprises one or more flexible epoxy resins, such as Masterbond EP21TDC-2LO (available from Masterbond, Hackensack, New Jersey), 3M TM cotch-Weld TM Epoxy Resin 2216B / A Gray (available from 3M Company, St. Paul, Minnesota) and 3M TM Scotch-Weld TM Epoxy Resin DP125. In yet other embodiments, the liquid adhesive comprises one or more acrylics, such as LOAD Adhesive 410 / Accelerator 19w / LOAD AP134 Primer, LOAD Adhesive 852 / LOAD Accelerator 25GB (both available from LOAD Corporation of Cary, North Carolina), DELO PUR SJ9356 (available from DELO Industrial Adhesives of Windach, Germany), Loctite AA4800, Loctite HF8000, TEROSON MS9399, and TEROSON MS647-2C (the latter four available from Henkel AG of Düsseldorf, Germany). In other embodiments, the liquid adhesive comprises one or more urethanes, such as 3M TM Scotch-Weld TM UrethaneDP640 Brown and 3M TM Scotch-Weld TM Urethane DP604. And in yet other embodiments, the liquid adhesive comprises one or more silicones, such as Dow Corning 995 (available from Dow Corning Corporation, Midland, Michigan).

[0032] Additionally, in embodiments, a primer may be applied to prepare the surfaces of the glass sheet 12 and the carrier 26 for better adhesion. In embodiments, in addition to or in lieu of applying a primer, the carrier 26 may be roughened to provide better adhesion between the adhesive 24 and the carrier 26. Additionally, in embodiments, an ink primer may be used in addition to or in lieu of primers for metal and glass surfaces. The ink primer helps provide better adhesion between the adhesive 24 and ink-covered surfaces (e.g., the pigment design described above for blank front applications). An example of a primer is 3M TM Scotch-Weld TM Metal Primer 3901 (available from 3M Company, St. Paul, Minnesota), and other commercially available primers are also suitable for use in the present disclosure and may be selected based on the surfaces involved in bonding and the adhesive used to create the bond.

[0033] The carrier 26 holds the glass sheet 12 in a curved shape with the aid of the adhesive 24 and a cold forming process (described below). The carrier 26 is also configured to be attached to a frame of a vehicle interior system, such as a Figure 1 Vehicle interior systems 100, 200, 300. Figure 2B As shown, the height H of the carrier 26 corresponds to the distance that the carrier 26 extends from the adhesive 24. In an embodiment, the height H is from 5 mm to 20 mm, more particularly from 8 mm to 12 mm.

[0034] Figure 2B The rear surface, i.e., the second major surface 16, of the V-shaped glass article 10 is shown. Figure 2B As shown, the carrier 26 includes a first strip 28 on a first side 30 of the glass sheet 12 and a second strip 32 on a second side 34 of the glass sheet 12. In an embodiment, the strips 28, 32 of the carrier are applied across the entire width of the bend region 20, and in an embodiment, the carrier 26 may extend as far as Figure 2A The flat portions 22a, 22b are shown. Figure 2B As can be seen in FIG, glass sheet 12 is substantially unencumbered by carrier 26. In certain embodiments, carrier 26 defines a border 36 over a portion of glass sheet 12. As used herein, "border" refers to the amount of glass sheet 12 that is not available for viewing a display (e.g., a display mounted to second major surface 16). In embodiments, the width W of border 36 is b At most 10 mm, more particularly at most 5 mm, and most particularly at most 2 mm.

[0035] Figure 3A An embodiment of a C-shaped glass article 40 is shown. The C-shaped glass article 40 also includes a glass sheet 12. Figure 2A and Figure 2B V-shaped glass products 10, Figure 3A The glass sheet 12 of the C-shaped glazing 40 has a first major surface 14 and a second major surface 16 defining a thickness T and connected by a minor surface 18. The C-shaped glazing 40 also has a curved region 20 and flat portions 22a, 22b. Compared to the V-shaped glazing 10, the C-shaped glazing 40 has a much larger curved region 20 and much smaller flat portions 22a, 22b. Figure 3A As can be seen in FIG, carrier 26 is connected to second major surface 16 by adhesive 24. Because bending area 20 is much larger than in the previously discussed embodiments, carrier 26 extends substantially along the entire side of each side 30, 34, as shown in FIG. Figure 3B However, the border 36 defined by the strips 28 , 32 of the carrier 26 remains at most 10 mm, more particularly at most 5 mm, and most particularly at most 2 mm.

[0036] As described above, carrier 26 of both V-shaped glazing 10 and C-shaped glazing 40 is made of a material having a CTE that matches the CTE of glass sheet 12. The matched CTE reduces thermal stresses in adhesive 24 due to differences in thermal expansion between glass sheet 12 and carrier 26. Figure 4 A graph depicts the shear stress generated in the adhesive 24 as a function of the CTE of the carrier 26. The CTE of the glass sheet 12 is approximately 8 (10 -6 ) / °C. Therefore, in an embodiment, the carrier 26 is selected to have a -6 ) / ℃ and about 40(10 -6 ) / °C, more particularly about 8(10 -6 ) / ℃ and about 22(10 -6 ) / °C, and even more particularly about 8(10 -6 ) / ℃ and about 15(10 -6 ) / °C, most particularly about 8(10 -6 ) / ℃ and about 15(10 -6 ) / ℃.

[0037] like Figure 4 As shown, the shear stress in the adhesive increases as the CTE increases further from the glass CTE. For example, the CTE of the carrier 26 of aluminum or magnesium is 23 (10 -6 ) / ℃ or 26(10 -6 ) / °C, and the shear stress generated at a temperature change of 75°C is approximately 1 MPa and 1.2 MPa. The CTE of the steel carrier 26 is approximately 10(10 -6) / °C, and the shear stress generated at a temperature change of 75°C is approximately 0.2 MPa. A temperature change of 75°C is used because the lowest temperature for thermal reliability testing in the automotive industry is typically 95°C, which has a temperature change of 75°C from room temperature (20°C). Based on the selected carrier material, the adhesive is selected to be able to withstand the combined shear stress and bending stress. Therefore, in embodiments, the adhesive 24 used with an aluminum or magnesium carrier 26 will need to have a higher bond strength than the adhesive used with a steel carrier 26.

[0038] Table 1 below considers various carrier materials used in combination with an adhesive having a bond strength of 0.6 MPa.

[0039]

[0040] In preparing Table 1, several assumptions were made. The total stress on the adhesive was estimated as the sum of the bending stress required to keep the glass sheet bent in line with the carrier and the shear stress caused by the CTE mismatch between the glass sheet 12 and the carrier 26. Regarding the bending stress, the bending stress of the C-shaped glazing 40 is greater due to its larger bending area 20. The maximum bending stress of the C-shaped glazing 40 was estimated as the maximum glass bending force divided by the area of ​​the 1 mm frame 36. The maximum bending force was calculated to be 200 N, and the area was 1000 mm. 2 , so the maximum bending stress is 0.2 MPa. Since the bending area 20 of the V-bend article 10 is small, it can be assumed that its maximum bending stress is less than 0.2 MPa. The shear stress is calculated for a temperature change of 75°C and is shown in column 4 of Table 1. Therefore, for each material in Table 1, its total stress is estimated to be the bending stress of 0.2 MPa plus the shear stress. Column 5 of Table 1 considers whether the total stress (Stress) is less than the strength of the adhesive (Strength). For the purposes of Table 1, it is assumed that the adhesive has a strength of 0.6 MPa (which corresponds to a polyurethane structural adhesive such as BETASEAL TM X2500Plus, available from The Dow Chemical Company, Midland, Michigan). Based on the fifth column (stress < strength), suitable materials for the carrier 26 include Kovar (Fe-Ni-Co alloy) and the two stainless steels tested. When combined with the maximum bending stress, the aluminum, magnesium, and plastic carrier materials all produced shear stresses that exceeded the long-term strength of the adhesive 24. Therefore, in order to use aluminum or magnesium as a carrier, a stronger adhesive would have to be used. Column 6 of Table 1 takes into account the cost of the materials used for the frame. As can be seen, the cost of stainless steel is within the range of commonly used aluminum and magnesium alloys, indicating that switching to a stainless steel carrier material is also economically feasible.

[0041] In an embodiment, when the adhesive is selected to have a bond strength greater than the combined shear stress and bending stress, the carrier 26 can be made of a material having a CTE between 8 (10 -6 ) / ℃ and 40(10 -6 ) / °C. Thus, a variety of metallic materials can be used, including steel (especially stainless steel, galvanized steel, and other corrosion-resistant steels), iron-nickel alloys, aluminum and its alloys, and magnesium and its alloys. Furthermore, the carrier material can be plastic or a composite material as described below. In this way, the carrier material and binder can be selected from a wide variety of materials, allowing for design and economic flexibility.

[0042] In another embodiment, the carrier material may be a fiber reinforced plastic composite. For example, the carrier material may include a composite material having glass fibers embedded in an epoxy resin. The glass fibers have a Young's modulus of 720 GPa and a CTE of 5 (10 -6 ) / ℃. The Young's modulus of epoxy resin is 35GPa and CTE is 57.5(10 -6 ) / °C. The CTE of the composite will depend on the relative amounts of glass fiber and epoxy resin. Figure 5 A graph depicts the longitudinal CTE of composites with various glass fiber fractions. As expected for composites, the longitudinal CTE decreases with increasing fiber fraction (assuming there is more low CTE material). Figure 5 Describes a region where the -6 ) / °C, the CTE mismatch of the composite material is acceptable when used with glass sheets having a CTE of about 0.38 to about 0.52. In an embodiment, the acceptable fiber volume fraction is about 0.38 to about 0.52. In an embodiment, the fiber component of the composite material comprises at least one of glass fiber, carbon fiber, aramid fiber, or graphite fiber. In an embodiment, the plastic component of the composite material comprises at least one of epoxy, polycarbonate, acrylic, polyester, polyetherketoneketone (PEKK), polycarbonate / acrylonitrile butadiene styrene (PC / ABS), polypropylene, or phenolic resin. Furthermore, in an embodiment, the fibers can be aligned along the longitudinal axis of the carrier 26, which can be along the sides 30, 34 of the glass sheet 12.

[0043] Figure 6 A graph showing stress as a function of the CTE of the carrier material is shown. In particular, Figure 6 The specific stress of the adhesive 24 is shown in FIG. Figure 7 As shown in Figure 7The tensile component can be considered as the opening stress, i.e., pulling the glass sheet away from the carrier, which exerts tension on the adhesive 24. The shear component is associated with the CTE mismatch between the glass sheet 12 and the carrier 26, which causes shear in the adhesive 24. Back Figure 6 , the graph shows that the magnitude of both the tensile and shear components increases as the CTE of the carrier material increases. Figure 6 The diagram of considers the stresses associated with a glass sheet 12 having a length of 750 mm, a width of 150 mm, a radius of curvature of 2300 mm and a carrier 26 having a height H of 10 mm.

[0044] Figure 8 A graph shows the deflection of a glass sheet 12 bonded to a carrier 26 as a function of the carrier height H. The deflection is related to the CTE mismatch between the glass sheet 12 and the carrier 26, which is a result of the uneven expansion of the glass sheet 12 and the carrier 26 when heated. Due to the uneven expansion, the carrier 26 will (usually) expand more than the glass sheet 12, causing the assembly of components to deflect toward the glass sheet 12. Figure 8 , the deflection is modeled as a function of the carrier height H. It can be seen that the deflection decreases as the carrier height H increases for both the stainless steel and composite carriers.

[0045] Figure 9-1 5 depicts various embodiments of the carrier 26 mounted to the glass sheet 12. Figure 9 and Figure 10 A prototype V-shaped glass article 10 is depicted. Figure 9 It can be seen that the V-shaped glass product 10 and Figure 2A and 2B . That is, the carrier 26 comprises a first strip 28 on a first side 30 of the glass sheet 12 and a second strip 32 on a second side 34 of the glass sheet 12. In the illustrated embodiment, the V-shaped glazing 10 comprises an adhesive 24 that would typically be applied to the glass sheet 12 to attach the conventional carrier 26 to the glass sheet 12. As can be seen, the adhesive 24 defines a conventional frame width W. c , which is larger than the required size of the carrier 26 according to the present disclosure. In fact, according to embodiments of the present disclosure, all adhesive not provided under the strips 28, 32 of the carrier 26 can be removed, thereby substantially increasing the display area of ​​the glass sheet.

[0046] Figure 10Another embodiment of the carrier 26 is shown. The carrier 26 includes the first strip 28 and the second strip 32, but also includes a third strip 42 located between the first strip 28 and the second strip 32. The carrier 26 also includes a plurality of reinforcing strips 44 that extend from the first strip 28 through the third strip 42 and to the second strip 32. Figure 10 In the embodiment shown in FIG. 4 , there are three reinforcing strips 44. However, in other embodiments, there may be more or fewer reinforcing strips 44, such as from one to twenty reinforcing strips 44 (e.g., positioned periodically throughout the curved region 20 of the C-shaped glazing 40). Figure 10 Also depicted are a plurality of holes 46 formed in the first strap 28 and the second strap 32. These holes 46 are configured to receive push-type fasteners, for example, to attach the carrier 26 to a frame of a vehicle interior trim system.

[0047] Figures 11A-11C Another embodiment of the carrier 26 is depicted. The carrier 26 includes a segmented strip 48 that can be used as the first strip 28 or the second strip 32 or both the first strip 28 and the second strip 32 (e.g., Figure 11C ). The segmented strip 48 defines a plurality of detents 50 along the length of the segmented strip 48. The segmented strip 48 also defines a plurality of bonding surfaces 52 for adhering the segmented strip 48 to the glass sheet 12. Figure 11B As shown, the segmented strip 48 has a zigzag configuration that allows for differential expansion on the side with the detents 50 and the side with the bonding surface 52. Thus, expansion of the frame of the vehicle interior trim system is not transferred to the glass sheet 12 and vice versa.

[0048] Figures 12A-12C Another embodiment of a segmented ribbon 48 that can be used as one or both of the first ribbon 28 and the second ribbon 32 of the carrier 26 is depicted. The segmented ribbon 48 includes a bonding surface 52 for attaching the segmented ribbon 48 to the glass sheet 12. However, Figures 12A-12C The segmented strip 48 also includes hooks 54 configured to engage with corresponding structures of the frame of the vehicle interior trim system. The segmented strip 48 includes a plurality of slots 56 that allow for differential expansion of the hook 54 side and the bonding surface 52 side.

[0049] Figures 13A-13C Another embodiment of a carrier 26 is depicted on a V-shaped glazing 10 (although the carrier 26 can also be used with a C-shaped glazing 40). Figure 13AAs can be seen in FIG, carrier 26 extends substantially around the perimeter of glass sheet 12. Carrier 26 includes an adhesive strip 58 connected to mounting strip 60. In the embodiment shown, adhesive strip 58 is arranged substantially perpendicular (e.g., within 10°) to mounting strip 60. Adhesive strip 58 is configured to be connected to glass sheet 12 using adhesive 24. Figures 13A-13C In the embodiment of FIG. 5 , the mounting strip 60 includes a plurality of holes 62 through which fasteners 64 may be inserted to connect the carrier 26 to the frame of the vehicle interior trim system.

[0050] Figure 14A and Figure 14B Another embodiment of the carrier 26 is depicted on a C-shaped glazing 40 (although the carrier 26 can also be used with a V-shaped glazing 10). Figure 14A As shown, the carrier 26 includes a first strip 28 and a second strip 32 located at the sides 30, 34 of the glass sheet 12. Figure 14B As can be seen in FIG. 2 , edge 66 of strip 28 is adhered to second major surface 16 of glass sheet 12 . Figure 14B It is also shown that the height H of the strip 28 far exceeds the thickness T of the strip 28. S As described above, a larger height H (e.g., at least 10 mm) reduces the amount of deflection due to CTE mismatch, and a smaller thickness (e.g., less than 2 mm) reduces the size of the C-shaped glass frame 36. The strip 28 includes a plurality of holes 62 through which fasteners 64 can be inserted to connect the carrier 26 to the frame of the vehicle interior system. Figure 15A and 15B Depicts Figure 14A and 14B The carrier 26 is mounted on the frame 68 of the vehicle interior system. Figure 14B As shown, fasteners 64 inserted through holes 62 of strap 28 engage corresponding mating holes 70 located in frame 68 .

[0051] As briefly mentioned above, the glass sheet 12 is attached to the carrier 26 via a cold forming process. Cold forming refers to introducing the curved region 20 into the glass sheet 12 at a temperature below the softening temperature of the glass. More specifically, cold forming is performed at temperatures below 200°C, below 100°C, or even at room temperature. During cold forming, pressure is applied to the glass sheet 12 to conform the glass sheet 12 to the shape of the carrier 26. Pressure can be applied in a variety of ways, such as vacuum pressure, mechanical pressing, rollers, and the like. In embodiments, pressure is maintained on the glass sheet 12 until the adhesive 24 cures (at least sufficiently to prevent the glass sheet 12 from delaminating from the carrier 26). Thereafter, the glass sheet 12 is bonded to the carrier 26, and the glass article can be shipped and / or installed as part of a vehicle interior system.

Figure 16 , glass sheet 12 has a substantially constant thickness T1, with thickness T1 being defined as the distance between first major surface 14 and second major surface 16.

In other embodiments, W1 and L1 may be the average width and average length, respectively, of glass sheet 12.

[0058] Strengthened glass performance

[0059] As described above, the glass sheet 12 can be strengthened. In one or more embodiments, the glass sheet 12 can be strengthened to contain compressive stress extending from the surface to the depth of compression (DOC). This compressive stress region is balanced by a central portion exhibiting tensile stress. At the DOC, the stress transitions from positive (compressive) stress to negative (tensile) stress.

[0060] In various embodiments, the glass sheet 12 can be mechanically strengthened by exploiting the mismatch in thermal expansion coefficients between portions of the article to create regions of compressive stress 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 its glass transition point and then rapidly quenching it.

[0061] In various embodiments, the glass sheet 12 can be chemically strengthened by ion exchange. During ion exchange, ions at or near the surface of the glass sheet are replaced with or exchanged for larger ions of the same valence or oxidation state. In those embodiments in which the glass sheet comprises an alkali aluminosilicate glass, the ions and larger ions in the surface layer of the article are monovalent alkali metal cations, such as Li + 、Na + , K + , Rb + , and Cs + Alternatively, the monovalent cations in the surface layer may be replaced by monovalent cations other than alkali metal cations, such as Ag + Etc. In these embodiments, the monovalent ions (or cations) exchanged into the glass sheet generate stress.

[0062] The ion exchange process is typically performed by immersing the glass sheet in a molten salt bath (or two or more molten salt baths) containing larger ions to be exchanged with smaller ions in the glass sheet. It should be noted that salt water baths may also be utilized. In addition, the composition of the bath(s) may include more than one type of larger ion (e.g., Na + and K +) or a single larger ion. Those skilled in the art will appreciate that the parameters of the ion exchange process (including but not limited to bath composition and temperature, immersion time, number of immersions of the glass sheet in the salt bath(s), use of multiple salt baths, additional steps such as annealing, washing, etc.) are generally determined by the composition of the glass sheet (including the structure of the article and any crystalline phases present) and the desired DOC and CS of the glass sheet resulting from strengthening. Exemplary molten salt bath compositions may include nitrates, sulfates, and chlorides of larger alkali metal ions. Typical nitrates include KNO3, NaNO3, LiNO3, NaSO4, and combinations thereof. The temperature of the molten salt bath typically ranges from about 380°C up to about 450°C, while the immersion time ranges from about 15 minutes up to about 100 hours, depending on the thickness of the glass sheet, bath temperature, glass (or monovalent ion) diffusivity. However, temperatures and immersion times different from those described above may also be used.

[0063] In one or more embodiments, the glass sheet may be immersed in a molten salt bath of 100% NaNO, 100% KNO, or a combination of NaNO and KNO at a temperature of from 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% KNO and from about 10% to about 95% NaNO. In one or more embodiments, the glass sheet may be immersed in a second bath after being immersed in the first bath. The first and second baths may have different compositions and / or temperatures. 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.

[0064] In one or more embodiments, the glass sheet may be immersed in a molten mixed salt bath comprising NaNO3 and KNO3 (e.g., 49% / 51%, 50% / 50%, 51% / 49%) at a temperature of less than about 420°C (e.g., about 400°C or about 380°C) for less than about 5 hours, or even about 4 hours or less.

[0065] Ion exchange conditions can be adjusted to provide a "peak" in the stress profile at or near the surface of the resulting glass sheet, or to increase the slope of the stress profile. The peak can result in a greater surface CS value. Due to the unique properties of the glass compositions used in the glass sheets described herein, this peak can be achieved using a single bath or multiple baths, where the bath(s) have a single composition or a mixed composition.

[0066] In one or more embodiments, when more than one monovalent ion is exchanged into the glass sheet, the different monovalent ions may be exchanged to different depths within the glass sheet (and generate different amounts of stress at different depths within the glass sheet). The relative depths of the resulting stress-generating ions may be determined, resulting in different characteristics of the stress distribution.

[0067] CS is measured using means known in the art, such as a surface stress meter (FSM) utilizing a commercially available instrument, such as the FSM-6000 manufactured by Orihara Industrial Co., Ltd. (Japan). Surface stress measurement relies on accurate measurement of the stress-optical coefficient (SOC), which is related to the birefringence of the glass. The SOC is, in turn, measured using methods known in the art, such as the fiber bend method and the four-point bend method (both described in ASTM Standard C770-98 (2013), entitled "Standard Test Method for Measurement of Glass Stress-Optical Coefficient," the contents of which are incorporated herein by reference in their entirety), as well as the bulk cylinder method. As used herein, CS may be the "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, resulting in a "buried peak" in the compression profile.

[0068] DOC can be measured by FSM or by a scattered light polariscope (SCALP) (such as the SCALP-04 scattered light polariscope available from Glasstress Ltd., located in Tallinn, Estonia), depending on the strengthening method and conditions. When the glass sheet is chemically strengthened by an ion exchange process, either FSM or SCALP can be used, depending on which ions are exchanged into the glass sheet. In the case where stress is induced in the glass sheet by exchanging potassium ions into the glass sheet, DOC is measured using FSM. In the case where stress is induced in the glass sheet by exchanging sodium ions into the glass sheet, DOC is measured using SCALP. In the case where stress is induced in the glass sheet by exchanging both potassium and sodium ions into the glass sheet, DOC is measured using SCALP, because it is believed that the exchange depth of sodium indicates DOC, and the exchange depth of potassium ions indicates the change in the magnitude of compressive stress (but not the change from compressive stress to tensile stress); the exchange depth of potassium ions in such glass sheets is measured by FSM. Central tension, or CT, is the maximum tensile stress and is measured by SCALP.

[0069] In one or more embodiments, the glass sheet can be strengthened to exhibit a DOC (as described herein) described as a fraction of the thickness T1 of the glass sheet 12. For example, in one or more embodiments, the DOC can be equal to or greater than about 0.05T1, equal to or greater than about 0.1T1, equal to or greater than about 0.11T1, equal to or greater than about 0.12T1, equal to or greater than about 0.13T1, equal to or greater than about 0.14T1, equal to or greater than about 0.15T1, equal to or greater than about 0.16T1, equal to or greater than about 0.17T1, equal to or greater than about 0.18T1, equal to or greater than about 0.19T1, equal to or greater than about 0.2T1, or equal to or greater than about 0.21T1. In some embodiments, the DOC may be in the range of from about 0.08T1 to about 0.25T1, from about 0.09T1 to about 0.25T1, from about 0.18T1 to about 0.25T1, from about 0.11T1 to about 0.25T1, from about 0.12T1 to about 0.25T1, from about 0.13T1 to about 0.25T1, from about 0.14T1 to about 0.25T1, from about 0.15T1 to about 0.25T1, from about 0.08 T1 to about 0.24T1, from about 0.08T1 to about 0.23T1, from about 0.08T1 to about 0.22T1, from about 0.08T1 to about 0.21T1, from about 0.08T1 to about 0.2T1, from about 0.08T1 to about 0.19T1, from about 0.08T1 to about 0.18T1, from about 0.08T1 to about 0.17T1, from about 0.08T1 to about 0.16T1, or from about 0.08T1 to about 0.15T1. In some cases, the DOC may be about 20 μm or less.In one or more embodiments, the DOC may be about 40 μm or greater (e.g., from about 40 μm to about 300 μm, from about 50 μm to about 300 μm, from about 60 μm to about 300 μm, from about 70 μm to about 300 μm, from about 80 μm to about 300 μm, from about 90 μm to about 300 μm, from about 100 μm to about 300 μm, from about 110 μm to about 300 μm, from about 120 μm to about 300 μm, from about 140 μm to about 300 μm, from about 150 μm to about 300 μm, from about 40 μm to about 290 μm, from about 40 μm to about 280 μm). In some embodiments, the DOC is from about 40 μm to about 200 μm, from about 40 μm to about 180 μm, from about 40 μm to about 160 μm, from about 40 μm to about 150 μm, from about 40 μm to about 140 μm, from about 40 μm to about 130 μm, from about 40 μm to about 120 μm, from about 40 μm to about 110 μm, or from about 40 μm to about 100 μm. In other embodiments, the DOC falls within any of the specific numerical ranges set forth in this paragraph.

[0070] In one or more embodiments, the strengthened glass sheet may have a CS (which may be seen at the surface or at depth within the glass sheet) of about 200 MPa or greater, 300 MPa or greater, 400 MPa or greater, about 500 MPa or greater, about 600 MPa or greater, about 700 MPa or greater, about 800 MPa or greater, about 900 MPa or greater, about 930 MPa or greater, about 1000 MPa or greater, or about 1050 MPa or greater.
