ABSTRACT:
Disclosed are laminated windshields, preferably having an outer protective sheet of glass or plastic, at least two relatively thin structural sheet members of polycarbonate resin and interlayers of elastomeric resin interposed between and adhering said sheet and sheet members together. The thickness and material composition of the structural sheet members and interlayers are selectively correlated so that they function as an efficient energy absorber over a wide range of temperatures, such that forces emanating from a predesigned or preestablished impact on the outer sheet member are dissipated without penetration of the windshields.
