<p>PROBLEM TO BE SOLVED: To provide a method for producing a carbon fiber-reinforced composite material, which does not cause inhibition of polymerization when applied to RIM (Reaction Injection Molding) molding using polyamide.SOLUTION: A method for producing a polyamide fiber-reinforced composite material by reaction injection molding comprises: mixing (a) a liquid lactam compound a containing an anionic polymerization catalyst and (b) a liquid lactam compound b containing an activator for anionic polymerization at a prescribed ratio; impregnating (c) a carbon fiber bundle, comprising carbon fibers for resin reinforcement having polyurethane c with blocked isocyanate groups adhered to the surface, with the mixture; and polymerizing the mixture. Here, the lactam compound a and the lactam compound b may be the same compound or different.</p> |
