PROBLEM TO BE SOLVED: To provide a conjugant of fiber reinforced composite material composed of a thermoplastic resin as matrix which is excellent in strength, rigidity, lightness, and mass productivity.SOLUTION: The conjugant is obtained by vibration-welding a reinforcing material respectively having at least one layer of a random layer in which chopped carbon fibers are randomly oriented in a thermoplastic resin, and at least one one-directional material layer in which continuous carbon fibers are aligned in one direction in a thermoplastic resin with an open cross sectional material to be reinforced having at least one layer selected from the group consisting of a random layer and one directional layer so as to give a hollow closed cross section where the reinforcing material has a hat-like shape, and one of the random layer and the one-directional material layer is partially laminated to the other. |
