<p>PROBLEM TO BE SOLVED: To provide a fiber-reinforced composite material having excellent interlaminar toughness.SOLUTION: The fiber-reinforced composite material according to the present invention is a fiber-reinforced composite material composed of at least thermoplastic resin particles, a curable resin and a reinforcing fiber base material, the thermoplastic resin particles being thermoplastic resin particles which have been subjected to a heat treatment. The thermoplastic resin particles are preferably a curable resin insoluble thermoplastic resin. A method for producing a fiber-reinforced composite material according to the present invention includes: a step of subjecting thermoplastic resin particles to a heat treatment; a step of integrating the thermoplastic resin particles which have been subjected to the heat treatment, a curable resin, and a fiber base material; and a step of curing the curable resin. The step of subjecting the thermoplastic resin particles to the heat treatment is preferably a step of subjecting the thermoplastic resin particles to the heat treatment in a fluid.</p> |
