摘要： A pitch-based carbon fiber reinforced composite material is improved with regard to its compressive strength and compression strain at failure by combining polyacrylonitrile-based carbon fibers. The pitch-based carbon fibers have a modulus in tension of not less than 400 GPa, a tensile strength of not less than 2000 MPa, a compressive strength as a unidirectionally reinforced composite material of 100 MPa to 800 MPa and a fiber diameter of 4 .mu.m to 15 .mu.m and the polyacrylonitrile-based carbon fibers have a modulus in tension of not less than 200 GPa, a compressive strength and compression strain at failure as a unidirectionally reinforced composite material larger than those of the pitch-based carbon fibers, and a fiber diameter smaller than that of the pitch-based carbon fibers.
