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.

Abstract: A ballistic projectile resistant barrier apparatus combines the advantages provided by both high hardness material barriers and multiple laminate layer barriers. An outer tier of the barrier is comprised of a plurality of interconnected hard tiles. Each of the tiles has an outer, front surface designed that, upon impact by a ballistic projectile, the projectile is immediately deflected from its initial path. Subsequent tiers of the barrier are comprised of layers of a flexible material interspersed with layers of a ballistic liquid or at least one layer of ballistic fiber. When tiles are impacted by a projectile, the impacted tile is pushed into the laminate layers of the barrier, thereby substantially multiplying the area of the barrier that resists the impact force of the projectile as the projectile enters the barrier.
