PURPOSE:To obtain a high strength carbon-carbon composite material not causing breaking due to delamination by impregnating a polymer of a nitrogen-contg. heterocyclic compd. into a bundle of carbon fibers and carbonizing the polymer under pressure or carrying out further carbonization under ordinary pressure. CONSTITUTION:A nitrogen-contg. heterocyclic compd. such as quinoline, isoquinoline or acridine is polymerized with a catalyst to obtain a polymer as a precursor of a carbonaceous matrix. This polymer is impregnated into a bundle of carbon fibers and carbonized under pressure or under pressing or further carbonized under ordinary pressure as required. |
