IMPACT-RESISTANT GLASS-POLYMER LAMINATES AND SENSORS INCORPORATING THE SAME
Described are glass articles comprising a first glass-based layer, a second glass-based layer, and a polymer layer disposed between the first glass-based layer and the second glass-based layer. The first and second glass-based layers may comprise coefficients of thermal expansion that differ from one another by at least 0.5 ppm/ C. The first glass-based layer may comprise a thickness that is less than or equal to 300 m, while the second glass-based layer may comprise a thickness that is greater than 2.0 mm. The second-glass based layer may provide structural rigidity to the article, while the first glass-based layer may render impact-induced damage less visible and less prone to negatively effecting optical performance.
Laminated glass and its use
A laminate includes at least two sheets, one of the at least two sheets including a colored glass and another of the at least two sheets being a further sheet. The sheet including the colored glass in a wavelength range from 875 nm to 1600 nm has an internal transmittance at at least one wavelength of at least 75%. A connecting layer is disposed between the at least two sheets. The laminate has a thickness of at most 6 mm. The laminate in a wavelength range from 400 to 700 nm has an average transmittance .sub.avg,400 nm to 700 nm of less than 15% where .sub.avg,400 nm to 700 nm is defined as
and/or at each wavelength has a spectral transmittance of less than 15%.
Bendable glass stack assemblies, articles and methods of making the same
A glass element having a thickness from 25 m to 125 m, a first primary surface, a second primary surface, and a compressive stress region extending from the first primary surface to a first depth, the region defined by a compressive stress I of at least about 100 MPa at the first primary surface. Further, the glass element has a stress profile such that it does not fail when it is subject to 200,000 cycles of bending to a target bend radius of from 1 mm to 20 mm, by the parallel plate method. Still further, the glass element has a puncture resistance of greater than about 1.5 kgf when the first primary surface of the glass element is loaded with a tungsten carbide ball having a diameter of 1.5 mm.
Shaped glass laminates and methods for forming the same
Embodiments of a laminate including a first curved glass substrate comprising a first viscosity (poises) at a temperature of 630 C.; a second curved glass substrate comprising a second viscosity that is greater than the first viscosity at a temperature of 630 C.; and an interlayer disposed between the first curved glass substrate and the second curved glass substrate, are disclosed. In one or more embodiments, the first curved glass substrate exhibits a first sag depth that is within 10% of a second sag depth of the second curved glass substrate. In one or more embodiments, the first glass substrate and the second glass substrate exhibit a shape deviation therebetween of about 5 mm or less as measured by an optical three-dimensional scanner or exhibit minimal optical distortion. Embodiments of vehicles including such laminates and methods for making such laminates are also disclosed.
Laminated panes and windows formed therewith
A laminated pane for a window includes (1) a first sheet having a first thickness and a first coefficient of thermal expansion (CTE), (2) a second sheet of an inorganic glass having a second thickness and a second CTE, and (3) a polymer interlayer adhered between the first sheet and the second sheet including a layer of a first polymer material having a first elastic modulus and a layer of a second polymer material having a second elastic modulus, wherein the first CTE is greater than the second CTE, the second thickness is in the range of from 1 down to 0.3 mm, and the first elastic modulus is more than 20 times the second elastic modulus.
