発明の名称 (英語) JOINED BODY OF METAL AND RESIN MATERIAL コモンズ
発明の概要(英語) This joined body of a metal and a resin material has a configuration in which a plating film with a rough-surfaced structure is disposed on a surface of the metal, and the metal and the resin material are joined integrally with the plating film with the rough-surfaced structure interposed therebetween. A composite plating film of carbon nanotubes or a plating film with a random thin-plate structure can be used as the plating film with the rough-surfaced structure. Provided is the joined body of a metal and a resin material that can increase the joining strength in the joined body of the metal and the resin material, can suppress deterioration of the joining strength even if the joined body suffers repeated thermal stress, and has high durability.
従来技術、競合技術の概要(英語) BACKGROUND ART
Is an assembly of a metal and a resin material, electrical, electronic products in various industrial or motor vehicle, has been widely used as the structural material. Of the bonded structure of the metal and the resin material as an example of, for example, metal such as carbon fiber reinforced plastic (CFRP) of the bonded structure of the new material, as compared with a metal material, and light in weight, and high specific strength, heat resistance and is excellent in terms of an advantage. However, a resin material and the bonded structure is a metal, a metal and a resin material and is greatly different from the coefficient of thermal expansion, bonding strength with respect to the thermal history, there is a problem in bonding durability.
And a resin member of metal to improve the strength of the bonded body as a method, the metal to the bonding surface and the surface is roughened, and a resin member may be integrated with the metal by a method of improving bonding strength has been proposed. Joining the metal surface as a method to make the surface rough, using a mold having a finely textured metal by press working and a method of forming irregularities on the surface and, chemical etching, anodic oxidation, sand blasting, liquid honing method is used (Patent Document 1), a rough surface is formed by the laser processing method or the like (Patent Document 2). In addition, the metal material itself is processed, processing of the method as another method, plating using the uneven surface of the metal, by plating using the metal and is provided in the resin material and integrally joined to the method has been proposed (Patent Document 3, 4). Provided on the surface of metal using a rough surface (unevenness) of the metal and the resin material is improved by integrating the reason why the bonding strength, the adhesion area of the metal and the resin material can be enlarged, and a resin member of a metal according to the anchor effect between the two.
