PURPOSE:To obtain a method for producing high-strength and high-elastic modulus surface-modified pitch-based carbon fiber improved in bonding strength to a resin. CONSTITUTION:This method for producing surface-modified carbon fiber is to infusibilize pitch fiber obtained by spinning pitch, then burn the infusibilized pitch fiber in an inert gas atmosphere, subject the resultant carbon fiber to electrolytic oxidation treatment under conditions of >=50C/g electrical quantity and coat the surface of the treated carbon fiber with amorphous carbon according to a chemical vapor deposition method using a hydrocarbon gas as a raw material. |
