Abstract
A pre-fractured glass laminate that includes: a glass substrate comprising a thickness, a pair of opposed primary 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 within the plurality of cracks; a backing layer; and an interlayer disposed between one of the primary surfaces of the substrate and the backing layer. The compressive stress region extends from each of the primary surfaces to a first selected depth in the substrate. Further, the plurality of cracks is located in the CT region.
