In a metal-fiber reinforced plastic (FRP) composite, the FRP and the metal member are bonded together, so internal stress (thermal stress) is generated due to the misfit of coefficients of thermal expansion of the metal member and the FRP. Not only does the binder layer peel off and the mechanical properties of the FRP cannot be obtained, but also defects in appearance (surface strain) occur. Therefore, the technical problem is to secure the mechanical properties as a composite while easing the internal stress and keeping surface strain from being generated.

The metal-fiber reinforced plastic (FRP) composite according to the present invention solves the technical problem by sandwiching an FRP between two metal members and not having at least one of the metal members joined (bonded) with the FRP. Further, it is possible to arrange an intermediate member between the other metal member and the FRP and sandwich the FRP between the two metal members through the intermediate member.

A subframe assembly for a vehicle utilizing straight, parallel extruded longitudinal siderail members. This subframe assembly provides front-end (or rear-end) crash energy absorbance by plastically deforming, crumpling, and bending down to avoid the stackup and occupant cabin intrusion of components, such as the attached engine/motor, engine/motor mounts, steering components, and suspension components. The laterally disposed longitudinal siderail members each provide a straight, substantially uninterrupted lower load path to transfer crash energy from the lower load path crash management system beam and crashboxes or the like to a rear upper load path body in white bracket, and ultimately to the battery frame in the event of a crash, with the siderail members and crashboxes optionally being longitudinally coaxially aligned.

A vehicle body lateral section structure (10) is provided with a center pillar inner (41), a center pillar stiffener (42), a partitioning member (13), a filling material, a center pillar outer (43), and a sound insulation member (14). The center pillar stiffener forms a first closed cross-sectional portion (50) together with the center pillar inner. The partitioning member partitions a filling space (62) communicating with a first filling port and a second filling port inside the first closed cross-sectional portion. The center pillar outer forms a second closed cross-sectional portion (60) together with the center pillar stiffener. The sound insulation member is provided inside the second closed cross-sectional portion and foams when heated.

A vehicle center frame module includes a pair of side sills, each side sill including a side sill inner having a closed cross section and a side sill outer having a closed cross section, wherein an inboard side surface of the side sill outer and an outboard side surface of the side sill inner are joined, and a plurality of crossmembers connecting the pair of side sills in a transverse direction of a vehicle, the crossmembers including a first crossmember and a second crossmember disposed behind the first crossmember in a longitudinal direction of the vehicle.

A welded steel part obtained by welding a first sheet with a second sheet, at least one with a coating of aluminum alloy. The welding uses a welding wire which, after melting and cooling, constitutes a weld bead connecting the first sheet to the second sheet and being part of said welded steel part. The respective peripheral edge of the first and second sheets are in a joggled edge type configuration in which the peripheral edge of the first sheet is arranged above, and on or near the upper face of an end portion of the peripheral edge of the second sheet which is extended by an inclined junction portion, at least one part of the upper face of the inclined junction portion delimits at least laterally with the edge of the peripheral edge of the first sheet a groove receiving the weld bead, the inclined joining portion extending by a welding portion in longitudinal continuity with the peripheral edge of the first sheet.

The invention relates to an elongate steel structure (10) for a vehicle comprising:—first steel sheet element (11), and a second steel sheet element (12), said first and second steel sheet elements constituting opposite ends of the elongate steel structure and said first and second steel sheet elements overlapping each other in a mid-portion of said elongate steel structure, wherein the first and the second steel sheet elements have an overlapping hat profile including a central portion (17), two webs (18), and two flanges (19), wherein at least one of the first and second steel sheet elements include cut-outs (13) along the flanges (19) such that the overlap is interrupted along said flanges (19).

A vehicle roof having a fixed roof element having a glass, plastic or sheet metal panel provided with a circumferential molded section which is formed by a section foam molded to an edge or a section injection molded to the edge. A circumferential frame-like connecting plate may be fastened to the glass, plastic or sheet metal panel by means of the molded section and has a circumferential adhesive surface for attaching the fixed roof element to a vehicle body.

A trailer includes a housing including an internal frame and an external frame. The external frame is coupled to the internal frame. In certain embodiments, the internal frame is positioned between interior panels and exterior panels of the housing. In certain embodiments, the external frame is spaced from exterior panels.

A vehicle structure comprising a portion extending in a longitudinal direction, wherein the portion comprises a first member extending in the longitudinal direction and a second member extending in the longitudinal direction. The first member is configured to face an inside of a vehicle, and the second member is configured to face an outside of the vehicle. The first and second members are attached to one another to form a closed space between them. The portion comprises a wave-shaped first tubular reinforcement member located in the closed space.

A hollow chamber support assembly for a vehicle comprising a hollow chamber support, an insert component designed as a hollow chamber profile, which is arranged in the hollow chamber support with the outer sides of the walls of the insert component spaced apart from the inner wall of the hollow chamber support, and means for holding a first end section of the insert component on an end of the hollow chamber support in its arrangement provided in the hollow chamber support(. The means are designed as clamping means and comprise a clamping element and an abutment element, wherein to clamp the insert component, the clamping element is supported on the abutment element and, in this supported arrangement, acts against the outer side of at least one wall of the insert component.
