Abstract

Bullet proof armor comprising a laminated pad with front and rear surfaces and composed of a plurality of loosely related fabric sheets woven of fibres having high tensile strength, said fibres of the fabric adopted to establish gripping and holding engagement on the surface of bullets directed toward and impinging of said front surface and advancing into the pad, and metal abrading means comprising metal abrading particulate material at said front surface and adapted to abrade and condition the surface of bullets whereby the fibres of the fabric can better grip and hold onto the bullets.
