PROBLEM TO BE SOLVED: To provide a composite comprising a metal-shaped article and a thermoplastic resin composition having both of the advantage of a metallic housing and the advantage of a synthetic resin structure in the housing of an electronic device, an on-vehicle structural component or the like, and also to provide its manufacturing method. SOLUTION: The composite comprising the metal and the thermoplastic resin composition is manufactured by forming fine unevenness to the surface of the processed metal shaped article by a chemical etching method or the like, coating the treated metal shaped article with a urethane curable two-pack type ink/coating material, inserting the coated metal shaped article in an injection mold, and injecting a thermoplastic resin composition mainly comprising PBT in the mold. A filler for lowering the coefficient of linear expansion is added to the thermoplastic resin composition. The composite comprising the metal and the thermoplastic resin composition thus injection molded is extremely excellent in tensile shear breaking strength. COPYRIGHT: (C)2004,JPO&NCIPI |
