PURPOSE: To provide a carbon fiber reinforced composite material which develops high dynamical characteristics by using a carbon fiber in which PAN (polyacrylonitrile) series precursor is taken as a raw material. CONSTITUTION: An epoxy resin as a base resin, an acid anhydride as a hardening agent, and am imidazole catalyst as a catalytic hardener are used. An epoxy resin composition to which 0.1-3 pts.wt. of polymeric surface active agent having a carboxyl group as an additive is added, is used as a matrix resin. A carbon fiber taking a polyacrylonitrile series precursor as a raw material, is used as a reinforced fiber. Thus, a carbon fiber reinforced composite material is obtained. |
