Abstract
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.
