PURPOSE:To provide a carbon fiber-reinforced carbon composite material applicable to a cooler or a cooling fin for a nuclear fusion reactor, a highly integrated circuit or a computer part. CONSTITUTION:This carbon fiber-reinforced carbon composite material comprises a main part consisting of plural carbon yarns 2 arranged approximately in one direction, a carbon parent material 3 which is composed of carbon as a main component, packed between the carbon yarns 2 and has fine pores 30 and a filler 31 which is packed into the fine pores 30 of the carbon parent material 3 and made of Si and SiC. Since the filler 31 is packed into the fine pores in the composite material 1, the composite material has increased denseness, can make a coefficient of thermal expansion close to that of a metal or a silicon material constituting a highly integrated circuit and can prevent reaction between the carbon parent material and the carbon yarn and oxygen in air. Consequently, in the case of constituting a cooling fan or a heater element by using the composite material 1, cooling and radiating action are increased, release of a part, etc., hardly occurs and wear by oxidation can be avoided. |
