摘要

Reinforced composition epoxy resin precursor COMPOSITES, CARRYING ONE OR MORE epoxy resins POLIFUNCIONALES UNHARDENED, ONE OF WHICH AT LEAST CONTAINED IN THEIR STRINGS ONE OR MORE GROUPS divalent formula (I) wherein AYR, IDENTICAL OR DIFFERENT denote divalent aromatic radicals 6 to 20 carbons, X represents the radical -CH2-CHOH-CH2, p is zero or 1, n is a number ranging from 1 to 500, and a fibrous reinforcing material CONSISTING, in part or in its entirety, carbon fibers. APPLICATION OF THIS COMPOSITION FOR PRODUCING COMPOSITE MATERIALS WITH REINFORCEMENTS CARBON FIBER LONG IN PARTICULAR FROM composition as prepregs.
