A method for bonding components is provided. The method includes preparing a surface of a metal component, applying a film adhesive to the prepared surface, forming a thermoplastic component using injection molding such that the film adhesive is positioned between the metal component and the thermoplastic component, and curing the film adhesive.

A composite material with an insert-molded attachment steel is provided. The composite material includes a plurality of burring apertures, each of which has a flange in one direction on the attachment steel and is inserted between fibers. A resin is then introduced between the fibers in each burring aperture and external to the flange.

Example mechanical supports or mandrels are described for composite part curing. In one example, a mandrel includes a housing, and components within the housing and positioned to create a central opening. An expander is also positioned in the central opening, and the expander has a width that increases along a length of the expander. A narrow end of the expander is positioned in the central opening. An actuator is provided to move the expander into the central opening causing the components to expand the housing, and to retract the expander from the central opening causing the components to collapse the housing.

According to one embodiment of the present disclosure, a vehicle knuckle is provided. The vehicle knuckle according to one embodiment of the present disclosure may comprise a knuckle body provided with a wheel bearing installation hole configured to install a wheel bearing, and flanges extending from the knuckle body and used to connect the vehicle knuckle to other parts of a vehicle. The knuckle body and the flanges may be integrally formed of carbon chip materials.

A decorative molded component includes: a substrate having a shell extending along a mating surface and a through hole adjacent to the shell and defined along the mating surface; and a molded body coated to the mating surface, the molded body covering the through hole to be continuous from a skin bonded to the shell. The decorative molded component improves appearance while keeping the functions of the two members.

The invention relates to a frame, comprising, on each of its two sides relative to a vertical longitudinal center plane of the roof, a respective longitudinal beam made of sheet metal and at least one transverse beam made of sheet metal and connecting the two longitudinal beams to each other. The longitudinal beams and the at least one transverse beam are connected to each other via joint lines made of polyurethane foam. Moreover, a method for producing the frame is proposed.

A resin part for a vehicle includes a fender main body formed of a fiber-reinforced resin using a resin fiber, and a resin structure section formed of the same resin material as the resin fiber, provided at least on an outer surface of the resin part main body exposed on an outer side of a vehicle, and formed integrally with the resin part main body.

The present disclosure provides a metal-polymeric composite joint including a first component and a second component. The first component includes a metal. The first component has a first surface including a plurality of micro-anchors. The second component includes a composite material including a polymer and a reinforcing fiber. The second component has a second surface that at least partially engages the first surface of the first component. A portion of the polymer of the second component occupies at least a portion of the micro-anchors of the first component to fix the second component to the first component. In one aspect, the metal-polymeric composite joint further includes a passivation layer disposed between the first surface of the first component and the second surface of the second component.
