  • Publication number: 20140283986
    Abstract: A method for welding laser-impermeable resin members. The resin members are overlapped with each other at least partially, with a light absorber capable of absorbing laser light being interposed therebetween, so as to form an overlapping portion. The light absorber in the overlapping portion is irradiated directly with laser light, and is heated and melted thereby. Heat from the melted light absorber is transferred to the resin members in the overlapping portion, and therefore the resin members are melted in the overlapping portion. The melted overlapping portion is cooled and solidified, whereby the overlapping portion is integrally bonded.

  • Publication number: 20140272243
    Abstract: Linking parts are formed on one end of a first resin composite member and on one end of a second resin composite member in order to bond the ends together. For example, the linking parts may be wavy parts containing concave portions and convex portions. In this case, the wavy parts initially are heated and softened. Then, in a molding unit, respective pairs of confronting convex portions are overlapped with each other, and respective pairs of confronting concave portions are utilized to form a non-overlapping space. The overlapped convex portions are pressed and crushed, such that a base thermoplastic resin and fibers contained therein flow toward the non-overlapping space. Thereafter, the thermoplastic resin is cooled and hardened, whereby the first resin composite member and the second resin composite member are bonded integrally to obtain a resin composite structure.

  • Publication number: 20140272436
    Abstract: A water-repellent film is formed on a first joint surface of a first member that contains any one of a macromolecular material, a metallic material, and an inorganic material. The water-repellent film is subjected to an activation treatment, and is thereby converted into a film having a high hydrophilicity and a nylon 6 contact angle of less than 25°. A second joint surface of a second member that contains at least a thermoplastic resin, which differs from the macromolecular material, is placed on the first joint surface having the film, whereupon the second member is heated and melted. Then, the molten second member is cooled and solidified in order to bond the first joint surface and the second joint surface.
