Abstract: A composite molded article has (A) a fiber-reinforced resin molded article (A) including a fiber-reinforced resin having a polyamide-based resin as a matrix resin, a molded article (B) including a modified vinyl-based copolymer, and a molded article (C) including a styrene-based resin layered in this order. A layer (B) including a modified vinyl-based copolymer is interposed as a joining layer between a layer (A) of a fiber-reinforced resin having a polyamide-based resin as a matrix resin and a layer (C) including a styrene-based resin, whereby a composite molded article can be obtained in which the layers (A), (B) and (C) are strongly joined and integrated, and a composite molded article can be obtained which has excellent characteristics not realizable by a single layer of the layer (A) or the layer (C).

Abstract: A composite molded article is obtained by laminating (A) a fiber-reinforced resin molded article comprising a fiber-reinforced resin having a polyamide-based resin as a matrix resin, (B) a molded article comprising a polyolefin-based resin containing an epoxy group and/or a glycidyl group, and (C) a molded article having at least one selected from a polyester-based resin, a polyethylene-based resin and a polyarylene sulfide-based resin as a matrix resin, in this order, and a method produces the same.

Abstract: A composite molded article has a fiber-reinforced resin molded article (A) including a fiber-reinforced resin in which a polyamide-based resin is used as a matrix resin, a molded article (B) including an acid-modified-olefin-based copolymer, a molded article (C) including an unmodified-olefin-based polymer not containing an acid, and a molded article (D) including a polypropylene-based polymer layered in this order. The layer (B) including an acid-modified-olefin-based copolymer and the layer (C) including an unmodified-olefin-based polymer not containing an acid are interposed as joining layers between the layer (A) of the fiber-reinforced resin in which a polyamide-based resin is used as a matrix resin and the layer (D) including a polypropylene-based polymer, whereby a composite molded article can be obtained in which the layers (A), (B), (C) and (D) are strongly joined and integrated.

Abstract: A fusion-bonded body which includes a fusion-bonded part obtained by fusion-bonding to each other a first part to be fusion-bonded which comprises a first thermoplastic resin and first carbon fibers and a second part to be fusion-bonded which comprises a second thermoplastic resin and second carbon fibers. Also provided is a method for producing the fusion-bonded body which comprises a fusion-bonding step in which the first part to be fusion-bonded is brought into close contact with the second part to be fusion-bonded, an electric current is caused to flow through the two parts to generate heat and melt the first thermoplastic resin and second thermoplastic resin, and the molten resins are solidified to form a fusion-bonded part.
