摘要： A carbonaceous preform, which is free from such drawbacks as delamination and is superior in formability and mass productivity, can be obtained by a process comprising the steps of fixing a laminate of stacked carbon fibers with a fixing jig in the absence of a binder, impregnating the thus-fixed laminate with a molten carbonaceous pitch, and carbonizing the impregnated laminate in a non-oxidative gas atmosphere.

摘要： A carbon/carbon composite is prepared without using any expensive carbon fiber fabric and without performing any complicated molding step prior to a densifying step. More specifically, a pitch-based infusiblized fiber alone, or optionally in the form of a mixture thereof with a pitch-based carbonized fiber, is subjected to carbonization and molding under uniaxial pressing to obtain a carbon/carbon composite preform. The preform is then densified using a carbonaceous matrix.
