PURPOSE:To provide a method for industrially producing a carbon fiber reinforced carbon composite material by which a high density and high strength composite structure can be efficiently produced. CONSTITUTION:A matrix binder made of a liq. thermosetting resin is impregnated into carbon fibers and they are combined, molded and fired in a nonoxidizing atmosphere to carry out carbonization. In this process, a resin compsn. having 0.5-50P viscosity prepd. by mixing phenolic resin having >=100mol.wt., >=50% nonvolatile matter content and 15-60min gelling time with furan or a deriv. thereof is used as the matrix binder. |
