    摘要： A process for producing pitch-derived carbon fibers from pitch fibers produced by melt-spinning a carbonaceous pitch, which comprises adding a polyoxyethylene alkyl ether of the following formula [I]:
    wherein R represents an aliphatic hydrocarbon having 8 to 12 carbon atoms and n represents an integer of 3 to 9,
    as an emulsifier in an amount of 1 to 12 wt. %, based on an amino-modified silicone oil, to this oil having a molecular weight of 500 to 5,000 and an amine value of 2 to 15 to obtain an aqueous silicone emulsion and then applying the thus obtained emulsion to the pitch fibers when or before bundling the pitch fibers thereby adhering said oil to the pitch fibers in an amount of 0.01 to 0.8 wt. % based on the fibers.

    摘要： A process for producing a pitch-based graphite fiber comprises treating a pitch fiber in an oxidative gas atmosphere to render it infusible, said pitch fiber being obtained by melt-spinning a carbon-aceous pitch, then heat-treating the infusiblized fiber at 400-750 °C in an inert gas atmosphere to obtain a precarbonized fiber substantially containing oxygen, then raising the temperature to 2,000-3,000 °C at a rate of 500 °C or higher per minute in an inert gas atmosphere and heat-treating the precarbonized fiber at the raised temperature of 2,000-3,000 °C in said inert 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.
    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.
