The fluororesin composite material with high mechanical strength characteristics and wear resistance comprising 99 to 40 parts by weight of a fluororesin, e.g. polytetrafluoroethylene, and 1 to 60 parts by weight of a carbon fiber wherein the carbon fiber has an interplanar spacing d(002) of 3.36 to 3.45 ANGSTROM , a c-axis crystallite dimension (Lc) of 35 to 400 ANGSTROM and an a-axis crystallite dimension (La) of 40 to 800 ANGSTROM . The carbon fiber obtained by heat-treating a precursor fiber, previously infusiblized or flame resistance-treated, in an inert gas containing 20 to 5,000 ppm of an oxygen-containing gas at a temperature of 2,500 DEG to 3,00 DEG C.
