APPARATUS, METHODS AND SYSTEM FOR IMPROVED LIGHTWEIGHT ARMOR PROTECTION

摘要

An apparatus, method and system to enhance the performance of composite armor by utilizing energy of the threat projectile. The frontal member includes a plurality of concentric grooves on the face opposite of the surface impacted by a projectile, and the grooves mate with a complimentary plurality of concentric channels in a backing plate. The force from the impacting projectile presses the grooves of the frontal member into engagement with the channels of the backing plate. The groove design causes the backing plate to impart a compressive load into the backside of the frontal member, preventing it from prematurely fracturing in tension at the onset of the projectile penetration. The angles of each concentric groove are individually selected to cause the groove induced compressive loads to match the frontal member tensile loads from the penetrating projectile, maintaining the structural integrity of the frontal member until the projectile is defeated.
