Abstract : Tests have recently been conducted at this arsenal on five (5) samples of nylon-rubber (2), fiberglass-resin (2) and nylon-resin (1) laminates developed by the U. S. Rubber Co. The resistance of each of these laminates to perforation by cal. .45 steel-jacketed ball projectiles was so low that tests with other fragment-simulating projectile were foregone. The nylon-rubber laminates tested, while apparently very well fabricated, failed to afford the amount of protection desired, whereas the fiberglass-resin and nylon-resin laminates neither appeared to be properly fabricated nor did they furnish the desired protection. Although a fiberglass-resin combination has not been tried, it is seriously doubted that such a combination will afford sufficiently increased resistance to warrant its consideration as body-armor component since it will undoubtedly retain the weakness inherent in the nylon-rubber combination - the exposure of the cloth constituents to individual attack.
