PURPOSE:To manufacture the titled material of a high reinforcing efficiency, by impregnating under pressure Al or Mg metal in liquid state to carbon fiber covered with film of carbon or mixture of carbon and metal carbide and boron nitride, etc. CONSTITUTION:Carbon fiber is covered with film composed of >=95% carbon, at least one among mixture of carbon and metal carbide and BN as main components. Carbides of Si, Ti, Zr, Nb, Ta, W, etc., are suitable to the metal carbide. The film of 0.01-2mum thickness and carbon fiber calcined at 1,000-2,000 deg.C are favorable. To outside of the film, further film mainly composed of one kind or more of metal carbide, TiN, Si3N4 or that composed mainly of compd. contg. one or two kinds among Si, Ti, Al, B, Zr, and C, O can be covered. The covered carbon fibers and Al or Mg metal in liquid state are contacted, pressed and composited by >=10kg/cm<2>, favorably about 100-1,100kg/cm<2> pressure, to obtain fiber reinforced composite material.
