Joining method for joining fiber-reinforced thermoplastic resin material and object to be joined, and fiber-reinforced plastic product

摘要

PROBLEM TO BE SOLVED: To provide a novel jointing method for jointing a fiber-reinforced thermoplastic resin material and a joint object such as a metal.SOLUTION: A jointing method for jointing a fiber-reinforced thermoplastic resin material 11a, in which a thermoplastic resin cyclic oligomer is made matrix, and a joint object 80 is characterized by comprising: an installation step of setting a press molding mold 50 capable of being heated to a predetermined temperature, with one or two or more sheet-shaped fiber-reinforced thermoplastic resin material of fibers impregnated with a thermoplastic resin cyclic oligomer as a matrix, and a joint object; a heating step of heating the fiber-reinforced thermoplastic resin material disposed in the molding mold; and a compression step of ring-opening polymerizing the thermoplastic resin cyclic oligomer of the fiber-reinforced thermoplastic resin material, into a predetermined shape.SELECTED DRAWING: Figure 6
