Method for producing CFRTP composite

摘要

PROBLEM TO BE SOLVED: To produce a CFRTP composite body in which a metal material, a CFRTP, a matrix resin of a CFRTP, and the like are laminated by injection molding.SOLUTION: A method for producing a CFRTP composite body includes inserting both a CFRTP shaped article 1 and an aluminum alloy plate 9 into a cavity 13 of an injection mold 10, and injecting a crystalline thermoplastic resin which contains a matrix resin of a CFRTP as a main component. The injected resin intrudes into a clearance 18 between a metal plate 9 of which a surface has been subjected to chemical treatment and that is formed of a titanium alloy, an aluminum alloy, and the like and the CFRTP shaped article 1, and integrally sticks (joins) the aluminum alloy plate 9 and the CFRTP shaped article 1. A CFRTP composite body with an aluminum alloy plate is obtained.SELECTED DRAWING: Figure 4
