To solve the conventional problem that direct reaction between metal and carbon fiber in a metal-matrix carbon-fiber-reinforced composite material causes the deterioration of the carbon fiber and the expected characteristics, such as strength, Young's modulus, high thermal conductivity and low thermal expansion, cannot be exhibited and to find the various characteristics of the metal-matrix carbon-fiber-reinforced composite material and to provide the material having excellent weatherability and heat resistance by suppressing the above reaction.
In manufacturing the carbon-fiber compact, an organic precursor which remains in the form of carbon on firing in a nonoxidizing atmosphere is used as a binder so that the resultant residual carbon can be interposed later between the molten metal and the carbon fiber to prevent the direct reaction. Deterioration in strength of the carbon fiber can be prevented. In the method for manufacturing the metal-matrix carbon-fiber-reinforced composite material, composing with the metal is performed by pressing the molten metal into the carbon compact under high pressure.
