ABSTRACT:
A composite containing a network of ultrahigh molecular weight polyethylene or polypropylene fibers of high tenacity and modulus and a matrix which has ethylene or propylene crystallinity, e.g. polyethylene, polypropylene or copolymers. The composite can be formed by heating the matrix to its melting or sticking temperature around the fibers. The composite retains a high proportion of the tenacity of the fiber.
