<p>PROBLEM TO BE SOLVED: To provide a carbon fiber-reinforced thermoplastic resin composition having excellent interfacial adhesion properties between a carbon fiber and a thermoplastic resin and excellent dynamic properties.SOLUTION: The carbon fiber-reinforced thermoplastic resin composition contains the sizing agent-applied carbon fiber and the thermoplastic resin. The sizing agent contains, at the least, an aliphatic epoxy compound (A) and an aromatic epoxy compound (B1) being an aromatic compound (B). The sizing agent-applied carbon fiber has 0.50-0.90 of a ratio ((a)/(b)) of (a) the height (cps) of a component of the bond energy (284.6 eV) belonging to CHx, C-C, and C=C to (b) the height (cps) of another component (b) of the bond energy (286.1 eV) belonging to C-O when these heights are obtained from the Cinner shell spectrum drawn when the surface of the sizing agent is measured by an X-ray photoelectron spectroscopic method using Al(Kα) as an X-ray source at 15° photoelectron escape angle.</p> |
