Abstract
The present invention is a composite comprising a fibrous web and a matrix composition nonuniformly distributed in the major plane of a fibrous web.
Claims17
A composite comprising at least one fibrous web comprising a network of unidirectional fibers;
- and a matrix composition nonuniformly distributed in the major plane of the fibrous web.
A composite comprising at least one fibrous web, and from 2 to 15 volume percent of a polymeric composition nonuniformly distributed as a matrix for the fibrous web wherein distribution of polymer is in a pattern wherein there are areas of the composite which are thick areas having a greater polymer to fiber ratio than areas of the composite which are thin areas having a lower polymer to fiber ratio.
A composite comprising at least one fibrous web;
- and a matrix composition non-uniformly distributed in the major plane of the fibrous web, the composite having 93 to 98 percent by volume of fiber and having greater resistance to steel flechettes when tested according to Mil-Spec MIL-P 46593A(ORD) than a composite having a lower percent by volume of fiber.
