Document Type and Number:
WIPO Patent Application WO/2015/163218
Kind Code:
A1
Abstract:
A fiber-reinforced plastic joined body in which a fiber-reinforced molded article (X) containing carbon fibers and a thermoplastic resin, the fiber-reinforced molded article (X) having a joining surface (x), and a thermoplastic resin member (Y) having a joining surface (y) are welded via the joining surface (x) and the joining surface (y) by applying ultrasound to the fiber-reinforced molded article (X), wherein, in the fiber-reinforced plastic joined body, (1) the maximum value of tan δ by viscoelastic measurement of the fiber-reinforced molded article (X) is 70% or less of the maximum value of tan δ by viscoelastic measurement of the thermoplastic resin contained in the fiber-reinforced molded article (X) within a range of the glass transition temperature ±100ºC of the thermoplastic resin contained in the fiber-reinforced molded article (X), (2) the joining surface (x) and/or the joining surface (y) has an energy director, and (3) the application surface of the fiber-reinforced molded article (X) to which ultrasound is applied is smooth.
