The invention concerns a method for joining a metal component and a polymer component, and a structure comprising said components. In the method, an extrusion die plate with a through hole is placed between the metal component and the polymer component. A probe is rotated and plunged across the thickness of the metal component and eventually through said through hole of the extrusion die plate, thereby extruding a part of the metal component through said through hole of the extrusion die plate into the polymer component. The probe has a rotation axis having an offset to the centre of the through hole during the rotating and plunging action.

A method for manufacturing a composite member, in which a composite member having a high joining strength can be manufactured in an inexpensive and efficient way; and the composite member. A metal member and a resin-containing member are joined together by heating the metal member while pressing the resin-containing member against a metal porous film formed on a surface of the metal member. The porous film is formed by impacting the surface of the metal member with metal powder by the cold spray process.

An FRP reinforcing member configured to be used by being attached to an FRP molded body is provided with a plurality of laminated fiber layers being integrated with a resin. An FRP connecting structure includes FRP molded bodies being connected to each other or an FRP molded body and a member made of a material different from the FRP being connected to each other, by a bolt or a rivet. The FRP reinforcing member is attached to the FRP molded body so as to cover a periphery of a bolt hole or a rivet hole of the FRP molded body. An FRP molded body includes a recess or a hole formed on a surface. The FRP reinforcing member is mounted to the FRP molded body so as to cover an opening of the recess or the hole. An FRP reinforcing member producing method includes charging a plurality of fiber layers composed of glass fibers, carbon fibers, or aramid fibers and a resin into a mold, pressing the plurality of fiber layers and the resin at 300° C. or less for 60 minutes or less, and removing a load pressure, cooling, and then demolding after the pressing.

According to an aspect of the present disclosure, A method of manufacturing a composite member including an aluminum member and a resin member that are bonded to each other, the method including: blasting on a surface of the aluminum member to form asperities on the surface of the aluminum member; performing hydrothermal treatment on the surface of the aluminum member having the asperities to modify a surface of the asperities into aluminum hydroxide and form a surface nano structure on the surface of the asperities; applying a binder containing a triazine thiol derivative to the surface of the asperities of the aluminum member modified into aluminum hydroxide and having the surface nano structure to form a coating to be bonded to the aluminum member; and bonding the coating and the resin member.

A process for producing an interior trim part (1) with a decorative layer situated on a first side (S1) thereof and forming a decorative pattern (M) for the interior of a motor vehicle, the process comprising the following steps: (a) formation of at least one cutout configuration (R), defined by a predetermined decorative pattern (M), in a protective layer (120) situated on a first side (S1), which is situated on a first surface (110a) of the shell-shaped base body (110) made of a metallic material, (b) deposition of sinterable decorative material on the first side (S1) in such a way that the decorative material, as an intermediate layer (150), covers at least the area in which the cutout configuration (R) defined by the decorative pattern (M) is formed in the protective layer (120), (c) laser-sintering of the intermediate layer (150) inside the at least one cutout configuration defined by the decorative pattern (M), (d) removal of the sinterable decorative material that is situated outside the at least one cutout configuration defined by the decorative pattern (M),
as well as an interior trim part (1).

A ultrasonic welding method of joining dissimilar-material workpieces, such as sheet materials, and the joined components formed thereby. The method includes applying ultrasonic energy to a thermoplastic piece to fill a hole of a dissimilar piece to form a weld point that is made up with polymer from the thermoplastic piece. In general, the geometry of the thermoplastic piece is not altered during the process. The dissimilar piece generally has a higher melting temperate and can be metal, thermoset polymers, or other thermoplastic material. The welded pieces can be arranged in a lap, laminate, or double lap configuration. In some embodiments, the hole of the dissimilar sheet material includes undercut features that improve the mechanical interlock between the dissimilar pieces. In some embodiments, the weld point has a mushroom cap to improve mechanical interlock.
