A method may be used to produce a component that includes at least two different materials. The method may involve providing a hardenable planar or preformed steel sheet or steel profile, completely or partially heating the steel sheet or steel profile to the austenitic temperature, inserting the heated steel sheet or steel profile into a first tool for hot forming and/or press hardening the steel sheet or steel profile to give a completely or partially hardened steel workpiece. In the course of the hot forming and/or press hardening at least one jog is made in the steel sheet or the steel profile. The jog may serve for fastening at least one second material thereto.”

A soundproof material includes rubber sponge having a specific gravity of 0.2 or less, which is formed by extrusion molding and a subsequent crosslinking and foaming of a rubber composition using a microwave heating device. The rubber composition includes at least raw material rubber, a crosslinking agent, a foaming agent, and carbon black. The soundproof material has a rectangular cross-sectional outer shape, has at least two hollow parts inside formed by a lateral partition wall extending in a left-right lateral direction and at least two hollow parts formed by a vertical partition wall extending in a vertical direction. The method includes adding carbon nanotubes to the rubber composition.

The invention concerns a method for producing a hybrid-structure part of a motor vehicle, comprising shaping of a sheet of metallic material, the provision of a sheet of composite material, application of a layer of connecting material on a face of said metallic material sheet or on a face of said composite material sheet, the shaping of a hybrid element by shaping said composite material sheet to the shape of said metallic material sheet and joining the composite material sheet to the metallic material sheet by means of said connecting material layer, and the production of ngidification elements by overmoulding using a polymer material.

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.

The present disclosure relates to a method for producing a structural component for a motor vehicle, in particular a motor vehicle body component, which has a main body made of a metal material. The main body is provided at least partially with a reinforcing element made of a fiber-composite plastic. The method includes the steps of providing the main body, providing the reinforcing element, joining the main body and the reinforcing element together, and simultaneously heating the main body and the reinforcing element to a temperature and for a period of time which are chosen to be sufficiently high in order to harden both the metal material of the main body and also the fiber-composite plastic of the reinforcing element.

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.

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.

An assembly useful for providing structural reinforcement and/or sound/vibration damping to a hollow member of a motor vehicle is provided which contains an injection-molded carrier made of a heat resistant thermoplastic composition, at least one of the first side and the second side of the carrier has at least one receptacle adapted to receive and retain an insert comprised of a heat-expandable resin composition. The carrier may have a plurality of openings in at least one of the first side or the second side forming a grid or lattice and the assembly may include a mounting member adapted to fasten the carrier to an interior wall of a hollow member.

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.

In a method for connecting an attachment part to a structural part of a bodywork, a wall of the structural part is formed to at least partly encircle a region of the structural part. A form element is arranged to a main body of the attachment part. The attachment part is placed in the region of the structural part such that the form element touches the wall of the structural part, and the attachment part is pushed into the region, thereby causing the form element to move in relation to the main body of the attachment part until reaching an aperture in the wall of the structural part so that the form element moves into the aperture and is arranged therein to thereby position the attachment part in the region of the structural part.
