Title:

COMPOSITE MOLDED ARTICLE AND METHOD FOR MANUFACTURING SAME

Document Type and Number:

WIPO Patent Application WO/2017/110603

Kind Code:

A1

Abstract:

A composite molded article in which a fiber-reinforced resin molded article (A) comprising a fiber-reinforced resin in which a polyamide-based resin is used as a matrix resin, a molded article (B) comprising an acid-modified-olefin-based copolymer, a molded article (C) comprising an unmodified-olefin-based polymer not including an acid, and a molded article (D) comprising a polypropylene-based polymer are layered in this order, and a method for manufacturing the same. The layer (B) comprising an acid-modified-olefin-based copolymer and the layer (C) comprising an unmodified-olefin-based polymer not including an acid are interposed as adhesive layers between the layer (A) of fiber-reinforced resin in which a polyamide-based resin is used as a matrix resin and the layer (D) comprising a polypropylene-based polymer, whereby a composite molded article can be obtained in which the layers (A), (B), (C), and (D) are strongly bonded and integrated, and a composite molded article having excellent characteristics not achievable by the layer (A) or layer (D) alone can be obtained.
