    摘要： A composite material which has excellent ballistic performance and has improved flexibility. Surprisingly, it has been found that a combination of poly(alpha-olefin) fiber and matrix resin provides these desirable product features. The resin matrix is a block copolymer of a conjugated diene and a vinyl aromatic monomer, preferably a styrene-isoprene-styrene block copolymer, that is applied as an aqueous composition. The fiber has a tenacity of at least about 35 g/d and a tensile modulus of at least about 1200 g/d. The composite has a total density equal to or less than about 100 g/m2 and a stiffness of less than about 2.5 pounds (1.14 kg) for a two layer structure of the composite, and a total areal density equal to or less than about 190 g/m2 and a stiffness of less than about 3.0 pounds (1.36 kg) for a four layer structure of the composite. The Peel Strength for a two layer structure of less than about 1.0 pounds (0.45 kg) for a two layer structure of the composite, and less than about 0.7 pounds (0.32 kg) for a four layer structure of the composite. The process of this invention permits fabrication of these desirable products in a cost-effective manner. Body armor made from the composite has improved flexibility and excellent ballistic characteristics.

    摘要： Ballistic resistant composites and articles formed therefrom for use in airplanes and other vehicles which meets particular structural, impact and ballistic requirements. An aerospace-specification grade honeycomb is positioned between panels comprising non-woven ballistic resistant fibrous layers, and optionally one or more fire resistant layers. The composites and the articles formed therefrom have superior structural, impact, fire resistance and ballistic performance at a light weight.

    摘要： An impact resistant rigid composite has a plurality of fibrous layers, each of which comprise a network of filaments. The fibrous layers are disposed in a matrix, with elastomeric layer(s) therebetween. Prior to curing of the matrix, successive fibrous layers exhibit therebetween a peel resistance of at least about 3 g/cm. The composite has high rigidity combined with superior ballistic properties. When bonded at one or both surfaces to a hard plate selected from the group consisting of metals and ceramics, the composite affords increased protection against armor piercing projectiles.
