Abstract: The disclosure is of a penetration resistant panel which comprises plied layers of interwoven textile yarns of poly(p-phenylene terephthalamide) backed with plied layers of woven or non-woven fibers of Nylon 6,6. The panels of the invention are useful as ballistic-protective armor and are inherently lower in cost than similarly-effective panels comprised solely of poly(p-phenylene terephthalamide).

Abstract: A composite waterproof fabric for tent walls and the like which is suitable for use under severe service conditions, and which is opaque, of light weight and flame or fire resistant. The fabric comprises at least three plies, namely outer and inner woven, flame resistant plies and a middle ply of polytetrafluoroethylene which is hydrophobic, microporous and moisture vapor permeable. Tensile strength and tear resistance are imparted to the composite fabric largely by the inner ply, and abrasion protection is imparted by the outer ply. A light weight fabric of this construction is opaque, color adaptable and flexible at very low ambient temperatures.
