Abstract
A transparent armor construction having a laminate structure with at least two layers. The layers are constructed of two different materials selected from the group of glass, ceramic, resin, polymeric material, and plastic and in which the at least two layers include different coefficients of thermal expansion. The layers are bonded together and a planar frame having an open central section and an outer border is then bonded to the laminate structure. The material for the planar frame is selected so that it has a coefficient of thermal expansion less than the coefficient of thermal expansion of the laminate layer to which it is bonded.
