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.
