ABSTRACT:
A carbon/carbon composite is prepared by mixing 100 parts of a carbonaceous pitch with 1-45 parts by weight of at least one aromatic compound containing at least one functional group selected from nitro and hydroxyl groups, then impregnating a bundle of carbon fibers with the resulting mixture, thereafter carbonizing the thus-impregnated carbon fiber bundle under pressure or under pressing, and if necessary, further carbonizing the thus-carbonized carbon fiber bundle at atmospheric pressure.
