摘要:
A carbon/carbon composite is prepared by impregnating a bundle of carbon fibers with a polymer of a nitrogen-containing heterocyclic compound, carbonizing the thus-impregnated carbon fiber bundle under pressure or under pressing and, optionally, further carbonizing the thus-carbonized carbon fiber bundle at atmospheric pressure.
