Pre-crushed glass composites and laminates with impact resistance and methods of making the same
By introducing multiple cracks into a glass substrate and filling them with polymers or cured resins to form a pre-fragmented glass composite or laminate, the problem of glass materials being brittle under mechanical impact is solved, impact resistance is improved and processing costs are reduced, while maintaining optical performance and safety.

Abstract
A pre-crushed glass laminate comprising: a glass substrate comprising a thickness, a pair of opposed major surfaces, a compressive stress region, a central tension (CT) region, and a plurality of cracks; a second phase comprising a polymer or a cured resin in the plurality of cracks; a backing layer; and an interlayer disposed between one major surface of the substrate and the backing layer. The compressive stress region extends from each major surface to a first selected depth in the substrate. Further, the plurality of cracks are located in the CT region.
