PROBLEM TO BE SOLVED: To provide a prepreg and a fiber-reinforced composite material enhancing impact resistance while facilitating handling of nonwoven fabrics. SOLUTION: In a prepreg 1 produced by embedding in a thermosetting matrix resin a reinforcement substrate 2 in which reinforcement fibers 2a consisting of a continuous fiber are oriented, a nonwoven fabric 4 is disposed in which continuous fibers 4a made of a thermoplastic resin are oriented in the direction of orientation of the reinforcement fibers 2a, on the side of at least one of the prepreg surfaces from the reinforcement substrate 2. The fiber-reinforced composite material is produced by laminating and curing a plurality of the prepregs 1. The basis weight of the nonwoven fabric 4 preferably ranges 3-30 g/m<SP>2</SP>. Polyesters are preferably used as the primary component of the thermoplastic resin composing the continuous fibers 4a of the nonwoven fabric 4. COPYRIGHT: (C)2009,JPO&INPIT |
