    Abstract: PURPOSE:To produce a carbon fiber/carbon/metal composite material having high ordinary-temp. strength and good heat resistance by casting a molten metal into the open pores of the carbon fiber/carbon composite material consisting of carbon fibers and carbon matrix having the open pores. CONSTITUTION:Carbon fibers such as polycarylonitrile or the like and a carbonizable material such as a phenolic resin or the like are heated and pressurized in dies to form a composite molding. The composite molding is then heated to about 600-3,000 deg.C in inert gaseous flow to carbonize the above-mentioned carbonizable material and to form the carbon matrix having the pores open with each other around the carbon fibers by which the carbon fiber/carbon composite body is obtd. The melt of Al, Mg, Cu, Sn, Zn, Pb, Ni or an alloy consisting essentially of at least one l kind thereof is cast under the pressure exerted thereto into the above-mentioned open pores of such composite body and is solidified. The carbon fiber/carbon/metal composite material is thus easily obtd.
