The principles and embodiments of the present disclosure relate generally to complexly curved laminates made from a complexly curved substrate and a flat substrate, such as automotive window glazings, and methods of cold forming complexly-curved glass products from a curved substrate and a flat substrate. In one or more embodiments, the laminate includes first complexly-curved glass substrate with a first surface and a second surface opposite the first surface, a second complexly-curved glass substrate with a third surface and a fourth surface opposite the third surface with a thickness therebetween; and a polymer interlayer affixed to the second convex surface and third surface, wherein the third surface and fourth surface have compressive stress values respectively that differ such that the fourth surface has as compressive stress value that is greater than the compressive stress value of the third surface.

Disclosed herein are embodiments of a borosilicate glass composition having a unique fracture behavior. The borosilicate glass composition may be incorporated into a glass laminate including a first glass ply and a second glass ply. The second glass ply may comprise the borosilicate glass composition. The second glass ply may have a coefficient of thermal expansion of less than or equal to 5.1 ppm°/C. A combined thickness of the first glass ply and the second glass ply may be greater than or equal to 3.7 mm and less than or equal to 6.0 mm, and a ratio of the second thickness to the combined thickness is greater than or equal to 0.825. The second glass ply does not fail when the first major surface is impacted by a Vickers diamond impactor at an impact energy of 0.25 Joules.

The present disclosure relates to bullet-resistant laminated glass having at least three sheets of glass. One of the sheets of glass faces the impact side as a cover sheet, and one sheet of glass is formed as a closure sheet facing away from the impact side. Between the cover sheet and the closure sheet, one or more intermediate sheets are disposed, these sheets of glass being connected to each other by composite layers. The composite layers are formed by flexible and dimensionally unstable films and/or cast compounds. The composite layers do not consist of polycarbonate, polyurethane or polymethylmethacrylate. In order to prevent splinter output on the rear side, this glass composite has a closure sheet on the rear side consisting of thermally or chemically prestressed glass.

Provided are a strengthened glass panel for protecting a surface of a display device and a method for manufacturing the same. Here, the strengthened glass panel includes a strengthened glass layer, a laminate layer uniformly formed on the bottom surface of the strengthened glass layer, and a separation layer configured to cover the laminate layer, wherein the laminate layer is formed by transferring a transfer film. Accordingly, the strengthened glass panel for protecting a surface of a display device can have improved characteristics of neatly attaching the laminate layer to the surface of the display device without lifting or occurrence of air bubbles and easily detaching the laminate layer when a uniform laminate layer is formed on strengthened glass by means of a transfer film.

A stress-engineered frangible structure includes multiple discrete glass members interconnected by inter-structure bonds to form a complex structural shape. Each glass member includes strengthened (i.e., by way of stress-engineering) glass material portions that are configured to transmit propagating fracture forces throughout the glass member. Each inter-structure bond includes a bonding member (e.g., glass-frit or adhesive) connected to weaker (e.g., untreated, unstrengthened, etched, or thinner) glass member region(s) disposed on one or both interconnected glass members that function to reliably transfer propagating fracture forces from one glass member to other glass member. An optional trigger mechanism generates an initial fracture force in a first (most-upstream) glass member, and the resulting propagating fracture forces are transferred by way of inter-structure bonds to all downstream glass members. One-way crack propagation is achieved by providing a weaker member region only on the downstream side of each inter-structure bond.
