PCT No. PCT/JP92/00676 Sec. 371 Date Apr. 5, 1993 Sec. 102(e) Date Apr. 5, 1993 PCT Filed May 25, 1992 PCT Pub. No. WO93/03087 PCT Pub. Date Feb. 18, 1993.A carbon fiber prepreg comprising a unit layer consisting of carbon fibers and a matrix resin layer, and stranded filaments or single filaments incorporated thereinto. The steel fiber is an Ni plated low-carbon dual-phase steel filament and has a filament diameter of not more than 100 mu m, a tensile strength of 300 to 700 kgf/mm2, and an area reduction at fracture of more than 20%. The carbon fibers and steel filaments are aligned codirectionally, and the steel fiber content of the prepreg relative to the carbon fiber is not more than 10 vol %. Sheets of the carbon fiber prepreg are laminated to form a carbon fiber reinforced composite.
