摘要

The present invention provides a carbon fiber reinforced resin composition excellent in interfacial adhesion between a carbon fiber and a matrix resin and excellent in mechanical properties. The carbon fiber-reinforced resin composition of the present invention is a carbon fiber-reinforced resin composition comprising a sizing agent-coated carbon fiber coated with a sizing agent on a carbon fiber, and a matrix resin, wherein the sizing agent comprises an aliphatic epoxy compound (A) compound (B) as the aromatic epoxy compound (B1) to include at least, the sizing agent applied to the carbon fibers, the C _1s cabinet spectrum measured in the photoelectron escape angle of 15 ° by the sizing agent surface in the X-ray photoelectron spectroscopy (a (Cps) of the component of the bonding energy (284.6 eV) attributed to CHx, CC, C = C and the height (cps) of the component of bonding energy (286.1 eV) ) / (b) is 0.50 to 0.90.
