Abstract
Fabric laminates having superior resistance to penetration of fragments, such as shrapnel. The fabrics are formed of high-strength fibers consolidated with from about 7% to about 15% by weight of an elastomeric matrix composition, and in combination with protective layers of a polymer film on each surface of the fabric. The fabrics achieve a significant improvement in fragment resistance compared to fabrics of the prior art, while also maintaining excellent ballistic resistant properties.
