ABSTRACT The present invention provides an improved, complexcomposite article of manufacture which comprises a net-work of high strength fibers having a tensile modulus ofat least about 160 grams/denier and a tenacity of atleast about 7 g/denier. An elastomeric material sub-stantially coats each of the individual fibers, and hasa tensile modulus of less than about 6,000 psi, measuredat 25�C. The coated fibers are provided with at leastone additional rigid layer on a major surface of thecoated fibers to produce a rigid complex composite.Composites of this construction have improved resistanceto environmental hazards, improved impact resistance,and are unexpectedly effective as ballistic resistantarticles such as armor plate or helmets.
