Complex composite article having improved impact resistance

Abstract

The present invention provides an improved, complex composite article of manufacture which comprises a network of high strength fibers having a tensile modulus of at least about 160 grams/denier and a tenacity of at least about 7 g/denier. An elastomeric material substantially coats each of the individual fibers, and has a tensile modulus of less than about 6,000 psi, measured at 25.degree. C. The coated fibers are provided with at least one additional rigid layer on a major surface of the coated fibers to produce a rigid complex composite. Composites of this construction have improved resistance to environmental hazards, improved impact resistance, and are unexpectedly effective as ballistic resistant articles such as armor plate or helmets.
