A cold-formed glass laminate may include a first ply of 3D formed glass with a first thickness and a first strength. The first ply may include pre-formed residual compressive stresses in a peripheral edge portion adapted to offset tensile stresses resulting from a cold-forming process. The laminate may also include a second ply of 3D formed glass with a second thickness less than the first thickness and a second strength greater than the first strength. An adhesive may be arranged between the first ply and the second ply and post-formed residual stresses in the peripheral edge portion of the first ply of the laminate may remain compressive. A method of forming a glass laminate with compressive edge stresses is also described.

Disclosed herein are embodiments of a borosilicate glass composition as may be useful for windshield and other applications in particular due to unique fracture behavior.

The invention relates to a sunroof for a motor vehicle including two glass sheets (1, 3) joined together by a thermoplastic insert (2), wherein the sheet (1) directed toward the outside is annealed, and the sheet (3) directed toward the inside is made of tempered glass, the total thickness of the glass sheets being no greater than 5 mm, and preferably no greater than 4.5 mm.

A cold-formed glass laminate (100) may include a first ply (108) of 3D formed glass with a first thickness, a first strength, and a first coefficient of thermal expansion. The laminate (100) may also include a second ply (110) of 3D formed glass with a second thickness less than the first thickness, a second strength greater than the first strength, and a second coefficient of thermal expansion. The second coefficient of thermal expansion may be selected to be sufficiently higher than the first coefficient of thermal expansion to induce residual compressive stresses in the first ply (108) due to cold forming therewith. An adhesive layer (112) may be arranged between the first ply (108) and the second ply (110).

Transparent or translucent sound diffuser-absorbers include a first glass sheet of less than 0.8 mm thickness and a second glass sheet of less than 0.8 mm thickness with a transparent or translucent adhesive layer there between, the adhesive layer adhering the first and second sheets in a fixed configuration such that a first major surface of the first glass sheet has a smooth, repeatedly rising and falling shape. The diffuser-absorbers further include a plurality of through-holes extending through the first glass sheet and through the adhesive layer and through the second glass sheet. Methods of forming are also disclosed.

The laminated glazing proposed in this invention has an outer glass layer (201) with holes (20) and a thin inner facing glass layer (202) with shorter length dimension whereas the bottom edge (30) does not have holes on it and which does not overlap with the holes (20) in the outer glass layer (201). One or more retention layers (36), comprising reinforcement and adhesive layers, serve to connect the glazing mounting means (32) to both of the glass layers (201, 202) providing a thin laminated glazing with holes (20) that in the event of failure is retained by the mounting means (32).

A windshield according to the present invention includes a first glass plate that includes a first surface and a second surface, a second glass plate that includes a first surface and a second surface and is arranged such that the first surface of the second glass plate faces the second surface of the first glass plate, and an intermediate film that is sandwiched between the first glass plate and the second glass plate. The first glass plate includes a first end portion and a second end portion that is opposite to the first end portion, and a thickness of the first glass plate decreases from the first end portion toward the second end portion. In the first glass plate, a surface compressive stress on the first end portion side is higher than a surface compressive stress on the second end portion side.

The use of camera based safety systems is growing at a rapid rate in modern automobiles. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. This presents problems in the area of camera optics. Variations in the thickness of the glass and the plastic layer, surface mismatch, surface texture and the design curvature of the glass in conjunction with the often low installation angle, can reduce the optical clarity of the camera optics. These optical aberrations are further exacerbated during the lamination process when the layers are bonded together under pressure. The laminate of the invention utilizes a cutout in the plastic bonding layer in side of the laminate, preferable in the camera field of view. A laminating resin is used to fill the gap left by the cutout between the two glass layers.
