Abstract
The present invention relates to a unitary anti-ballistic composite armor of the type which comprises a base layer element and an energy absorbing body, the base layer element comprising a plurality of layers of reinforcing fibrous material embedded, in laminar relationship, in an organic polymeric shatter-resistant matrix, the base layer element also being adapted to entrap particles produced on impact of a projectile with said energy absorbing body. The composite armor in accordance with the present invention is characterized in that it also includes PA1 a frontal layer element, and PA1 said energy absorbing body is disposed between PA1 the frontal and base layer elements, said frontal layer element comprising a plurality of layers of reinforcing fibrous material embedded, in laminar relationship, in an organic shatter-resistant polymeric matrix, said frontal layer element being capable of deforming the geometry of the projectile, and said energy absorbing body being bonded to said frontal and base layer elements.
