    Abstract: Methods for preparation of high strength yarns having superior yarn-to-yarn uniformity of denier, tenacity and tensile modulus and uniform unidirectional fibrous sheets. Ballistic composites prepared from these yarns and fibrous sheets have improved uniformity of ballistic resistance.The drawn yarns, fibrous sheets and articles made therefrom are more uniform than the prior art and are useful in applications requiring impact absorption and ballistic resistance, such as body armor, helmets, breast plates, helicopter seats, spall shields; composite sports equipment such as kayaks, canoes, bicycles and boats; and in fishing line, sails, ropes, sutures and fabrics.

    Abstract: Ballistic resistant materials having improved strength and lighter weights. More particularly, improved ballistic resistant fabrics produced from drawn, high modulus fibers having a reduced fiber diameter and improved physical strength properties, without changing other properties such as fiber chemistry, binder resin type and binder resin content. The fabrics incorporate low denier per filament monofilament fibers, low denier per filament multifilament fibers, or a combination of low denier per filament monofilament fibers and low denier per filament multifilament fibers in a specialized fabric construction to form fine fiber layers and fabrics having enhanced strength and fiber areal density without altering the fabric weight, or having reduced fabric weight without a corresponding reduction in ballistic performance.
