ABSTRACT:
A transparent blast and ballistic projectile resistant barrier is comprised of a two-dimensional array of transparent hardened tiles that are encapsulated in a transparent resin layer. Preferably, the hardened tiles are transparent ceramic tiles, and the resin layer is a transparent polyurethane encapsulating the tiles. Additional transparent polycarbonate layers and glass fiber layers are also employed reinforcing the transparent barrier and providing the transparent barrier with polished exterior surfaces.
