Abstract: A process for preparing a laminated glazing comprises providing a first glass sheet formed into a desired shape with a first thickness by a first procedure and providing a second glass sheet formed into a desired shape with a second thickness by a second procedure with an interlayer located therebetween, and laminating together the first and second glass sheets and the interlayer at a temperature and pressure sufficient to adhere the interlayer material to the glass sheets and in which the process further comprises applying a mould which is shaped substantially the same as the first glass sheet, against the second glass sheet, during laminating to adhere the interlayer material to the two glass sheets such that after lamination, the shape of the second glass sheet is substantially the same as the shape of the first glass sheet.

Abstract: A glass article including an ultra-thin glass layer and an optically transparent polymeric hard-coat layer having a pencil hardness of 8H or more bonded to the ultra-thin glass layer. The optically transparent polymer hard-coat layer may include an organic polymer material or an aliphatic or aromatic hexafunctional urethane acrylate. In some embodiments, the glass article may have an impact resistance defined by the capability of the glass article to avoid failure at a pen drop height that is 2 times or more than that of a control pen drop height of the ultra-thin glass layer without the optically transparent polymeric hard-coat layer, where the pen drop height and the control pen drop height are measured according to the Pen Drop Test. In some embodiments, the glass article may survive a bend radius of 5 mm or less.

Abstract: A laminated glazing comprising first and second sheets of glass joined together by an interlayer structure comprising at least a first layer of adhesive interlayer material is disclosed. The surface compressive stress in a central region of a first major surface of the first sheet of glass is dependent upon the thickness of the first sheet of glass. For a thickness t of the first sheet of glass between 1.4 mm and 2.6 mm the minimum surface compressive stress CSmin (in MPa) in the central region of the first major surface of the first sheet of glass is given by CSmin (MPa)=21.0×t3−118.6×t2+236.9×t−a1, wherein a1 is between 135 MPa and 140 MPa. The second sheet of glass may be a sheet of chemically strengthened glass having a thickness between 0.3 mm and 1.0 mm. The laminated glazing may be fixed or movable in an aperture in a vehicle.

Abstract: A thin glass substrate, as well as a method and an apparatus are provided. The glass substrate has a glass having first and second main surfaces and elongated elevations on one of the main surfaces. The elevations rise in a normal direction, have a longitudinal extent that is greater than two times a transverse extent, and have a height, on average, that is less than 100 nm, and with a transverse extent of the elevation smaller than 40 mm. The method includes melting a glass, hot forming the glass, and adjusting a viscosity of the glass so that for the viscosity η1 for a first stretch over a first distance of up to 1.5 m downstream of a flow rate control component and y1 indicating a second distance to a location immediately downstream the flow rate control component the equation lg η1(y1)/dPa·s=(lg η01/dPa·s+a1(y1)) applies.

Abstract: A glass element having a thickness from 25 μm to 125 μm, 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 GI 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.
