Abstract:
Pre-impregnated composite material (prepreg) that can be cured/molded to form aerospace composite parts. The prepreg includes carbon reinforcing fibers and an uncured resin matrix. The resin matrix includes an epoxy component that is a combination of a hydrocarbon epoxy novolac resin and a trifunctional epoxy resin and optionally a tetrafunctional epoxy resin. The resin matrix includes polyethersulfone as a toughening agent and a thermoplastic particle component.

Claim (Index 20):
A method for making a composite part or structure according to  claim 16  wherein said reinforcing fibers comprise a plurality of carbon fiber tow which each comprises from 10,000 to 14000 carbon filaments wherein the weight per length of each of said carbon tows is from 0.2 to 0.6 grams per meter and wherein the tensile strength of each of said carbon tows is from 750 to 860 kilopounds per square inch and the tensile modulus of each of said carbon tows is from 35 to 45 megapounds per square inch.
