ABSTRACT:
A hard body armor system consisting of a boron carbide strike surface; aramid fiber layers; polyethylene fiber layers; two metallic foil layers with no binder between them; and a rigid foam layer; with carbon fiber layers on both surfaces. The metallic foil layers delaminate upon impact of a projectile, and the rigid foam layer provides room for the projectile to mushroom and expand, thereby reducing penetration and backface deformation. The system can be used in a configuration to protect the human torso; in a described embodiment, the front and back panels are interchangeable, and the two side panels are interchangeable. The panels, barrel-shaped to curve away from the torso, are held in proximity to each other by self-adjusting elastic.
