PURPOSE: A carbon fiber composite composition is provided to offer complicatedly shaped partial or completely molded product structures for vehicles with excellent rigidity, impact strength and high producibility. CONSTITUTION: A carbon fiber composite composition comprises 30-70 weight% of carbon fiber, 25-65 weight% of a polyamide, and 0.1-10 weight% of butyl benzene sulfonamide. The crystal size of the carbon fiber is 1-6 nm, and the average mono-fiber diameter is 1-20 microns. The polyamide is polyamide 6, of which the relative viscosity of the poly amide measured by a sulfate method(96%) is 1.5-3.5. The composite composition comprises the carbon fiber, polyamide, butyl benzene sulfonamide, and an additionally 1-15 weight% of an impact reinforcing agent.
