A vehicle frame structural member assembly method includes an elongated frame member and a reinforcement member. The reinforcement member is complementarily arranged adjacent the elongated frame member.

A battery frame including: a battery frame main body made of resin that is disposed at a vehicle body lower side of a floor panel and that supports a battery; and a ductile member made of metal that is integrally provided to the battery frame main body, that is fastened and fixed to a lower face side of the floor panel, and to which the battery is fastened and fixed.

A vehicle body includes a structural member having an inner surface defining an elongated cavity. The structural member includes an outer panel member joined to an inner panel member. A reinforcement member is positioned in the cavity wherein a gap is provided between the reinforcement member and the inner surface of the structural member. The reinforcement member includes an outer section, an inner section and a tension web interposed between and contacting the outer section and inner section. The outer section faces the outer panel member and the inner section faces the inner panel member. The tension web is secured to the outer panel member and inner panel member. An adhesive secured to the reinforcement member is activatable to expand toward the inner surface of the structural member to define a joint between the reinforcement member and the structural member and to at least partially fill the gap.

An outer panel is provided for a motor vehicle. That outer panel includes an outer panel body made from a non-ferromagnetic material and a ferromagnetic element connected to an inner surface of the outer panel body. The ferromagnetic element serves as a magnetic attachment point through the outer panel body for a magnetic accessory on the outer panel body of the motor vehicle.

This bonded structure includes a first member having a metal portion and a film portion disposed on at least a part of a surface of the metal portion; a second member; an adhesive layer for joining the first member and the second member to each other via the film portion. The film portion contains a resin and inorganic particles. The inorganic particles are formed of ferrosilicon or non-oxide ceramics containing V. Some of the inorganic particles protrude toward the adhesive layer. The particle size of at least some of the inorganic particles protruding toward the adhesive layer is less than the film thickness of the film portion.

A multi-material assembly is provided, as well as methods of making a multi-material assembly. The multi-material assembly includes a first coated structural component and a second structural component. The first coated structural component includes a first uncoated portion, and an adhesive is positioned between the second structural component and the first uncoated portion that secures the first coated structural component to the second structural component.

A panel for a trailer and a method of making the same is provided. The trailer includes a front wall, a rear wall opposite the front wall, a first sidewall, and a second sidewall. The first sidewall is formed by a first continuous laminate panel that extends an entire length of the first sidewall, and the second sidewall is formed by a second continuous laminate panel that extends an entire length of the second sidewall. The first continuous laminate panel and the second continuous laminate panel each comprise a first skin, a second skin opposite the first skin, and a perforated core between the first skin and the second skin.

The present teachings provide a reinforcement for a cavity. The reinforcement may include a carrier having a length extending along an axis between a first end and a second end. The carrier may include one or more longitudinal structures and one or more transverse structures. The carrier may also include one or more walls joined together to form one or more cavities extending along the axis. The carrier may have a cross-sectional shape roughly corresponding to the cross-sectional shape of interior of a hollow structural member. The device may also include a secondary material placed over the carrier. The secondary material is configured to expand, seal, reinforce, or a combination thereof upon application of a selectable stimuli and adhere to the interior of the cavity to provide reinforcement of the same.

A low floor electric bus is provided. The bus includes a frame extending longitudinally from a front end to a rear end, the frame having two sidepieces and a plurality of crossmembers extending between and coupled to the sidepieces, wherein the frame has a central section positioned at a lower height relative to the front and/or rear sections. The bus further includes a battery pack mounted to the central portion of the frame; a powertrain having an electric motor and a driveshaft, wherein the electric motor is mounted to the rear section of the frame behind a rear axle coupled to the frame and the driveshaft extends from the electric motor to the rear axle; and a cradle coupled to the front section of the frame. A mixed-material cabin is also provided. The cabin includes a passenger cabin with a floor, sidewalls, and ceiling having steel, ceramic, and composite components.

A long composite member (center pillar) includes a main member (pillar outer panel) that has a curvature in its longitudinal direction and whose shape of a cross-section perpendicular to the longitudinal direction protrudes on an outer side of the curvature, and a reinforcing member that is made of fiber reinforced plastic (CFRP) and is disposed on an inner side of the curvature with respect to the main member and within the cross-section of the main member. One end of the reinforcing member is adhered on a side of one end of the main member, and the other end of the reinforcing member is adhered on a side of the other end of the main member. An intermediary portion between the one end and the other end of the reinforcing member is extended straight within the cross-section of the main member.
