    Abstract: To provide a method for manufacturing a composite member including an aluminum die cast member and a polymer member firmly bonded by removing a carbide film on the surface of the aluminum die cast member to even the surface layer. The method includes: a melting step of melting a surface layer of a joint surface of the aluminum die cast member by irradiating the joint surface with a laser, the joint surface being joined with the polymer member; and a combining step of integrally molding a polymeric material on the joint surface. The method may have a removal step of removing the carbide film present on the joint surface by irradiating the joint surface with the laser before the melting step, and a modification step of irradiating the joint surface with plasma to impart a hydroxyl group to the joint surface after the melting step.

  • Publication number: 20180346723
    Abstract: Provided is a silicone rubber composition that has excellent storage stability and an improved post-curing compression set, and a silicone rubber cross-linked body made from the silicone rubber composition. A silicone rubber composition contains (a) an organopolysiloxane, (b) a cross-linking agent, and (c) a microcapsule type catalyst that is made from resin microparticles encapsulating a cross-linking catalyst, wherein the resin of (c) is one of a thermosetting resin that is thermally cured in the presence of the cross-linking catalyst and a thermosetting resin that is thermally cured in the absence of the cross-linking catalyst.
