Abstract

A fiber-reinforced composite material for increasing adhesive strength between a first composite material layer including a fibrous substrate with reinforcement fiber bundles arranged crosswise, and a second composite material layer including second reinforcement fibers arranged randomly. The first composite material layer including a fibrous substrate having reinforcement fiber bundles crossing and being drawn and aligned first reinforcement fibers; and first thermoplastic resin, with at least each of the reinforcement fiber bundles is impregnated; and a second composite material layer including second reinforcement fibers arranged randomly in second thermoplastic resin. The first composite material layer and the second composite material layer bonded to each other. The first composite material layer has bores on at least a surface thereof that is to be bonded with the second composite material layer. The second reinforcement fibers and the second thermoplastic resin enter into the bores.
