In accordance with an exemplary embodiment of the present invention, an optically clear polyurethane/polyurea polymer may comprises an impact resistant material comprising: a first polycarbonate layer; a second layer comprising a first elastomer; a third glass layer; a fourth layer comprising a second elastomer; and a fifth polymeric layer. In another exemplary embodiment, the third glass layer may be articulated and/or embedded in the second layer. Disclosed features and specifications may be variously controlled, adapted or otherwise optionally modified to improve and/or modify the performance characteristics of the transparent armor composite. Exemplary embodiments of the present invention generally provide lightweight transparent armor for use as, for example, bulletproof windows in vehicles and buildings.
