A method is provided of producing a component part for a motor vehicle. That method includes the steps of molding a first portion of an integral body from a chrome-platable material and molding a second portion of the integral body from a molded-in-color, non-platable material. This is followed by the applying of a chrome plate layer to the chrome-platable material. A component part or exterior grille made without masking and painting steps is also disclosed.

An automotive vehicle includes a body with a front portion and a rear portion. The vehicle additionally includes a spoiler coupled to the rear portion. The spoiler includes a first portion, a second portion, and a cap. The first portion includes a first plastic material, the second portion includes a second plastic material, and the cap includes a third plastic material. The second plastic material is distinct from the first plastic material. The second portion is disposed between the first portion and the cap. The second portion has a through hole extending therethrough. The cap has a diameter exceeding that of the through hole. The first portion and the cap are welded together via the through hole to mechanically secure the second portion to the first portion.

An automobile body structure is provided in which a carbon fiber-reinforced plastic cabin formed of a bathtub shape includes an inverted U-shaped roll bar providing a connection between front parts of a pair of left and right side frames, and a pair of left and right roll bar-supporting bars connecting an upper portion of the roll bar to rear parts of the pair of left and right side frames. Since a rear part of a roof panel and a front part of a tailgate panel are supported on a mounting bracket provided on the roll bar-supporting bar, it is possible, by changing the fore-and-aft position of the mounting bracket, to freely set the rear end position of the roof panel and the front end position of the tailgate panel and, moreover, it is possible to strongly support the roof panel and the tailgate panel.

A vehicle roof structure is provided capable of maintaining side collision performance of a vehicle even without a roof reinforcing member. The vehicle roof structure includes an annular frame that is joined to a circumferential edge of a roof panel (which includes an outer panel and an inner panel), and supports the roof panel. The annular frame has a higher rigidity than the roof panel, is arranged in an opening of a roof, and is joined to a pair of roof side rails, a front header, and a rear header.

A vehicle includes a fiber reinforced resin member, a reinforcing member, and a fixer. Thea fiber reinforced resin member at least includes a fragile portion. The reinforcing member covers the fragile portion and reinforces the fragile portion. The fixer fixes the reinforcing member to the fiber reinforced resin member.

In an embodiment, an energy-absorbing device can comprise: a polymer reinforcement structure, wherein the polymer reinforcement structure comprises a polymer matrix and chopped fibers; and a shell comprising 2 walls extending from a back and forming a shell channel, wherein the shell comprises continuous fibers and a resin matrix; wherein the polymer reinforcement structure is located in the shell channel.

A roof module for a motor vehicle comprises an RTM frame and a Class-A covering layer, which at least partially covers the frame and is made of polyurethane. A method for manufacturing a roof module comprises the following steps: Initially, a fiber mat is put into a first mold. Then, a reactive resin system is introduced into the closed mold and the resin cures, so that a blank is formed. The blank is put into a second mold, into which subsequently polyurethane is introduced in the open condition. The polyurethane expands, wherein it at least partially forms a Class-A surface.

A sealing structure of a door frame of a vehicle to seal a body weather strip disposed at a body and a side outer panel of the vehicle to prevent noise, the door frame including a fitting end bent to an outside at an upper end, an installing end protruding to an inside at lower side of the fitting end, and a curved portion contacting the body weather strip, may include an outside weather strip unit including an upper weather strip correspondingly contacting a side outer panel and a lower weather strip introducing a door glass integrally or monolithically formed at an upper surface and lower surface of a carrier disposed at a fitting end of the door frame, an inside weather strip disposed at an installing end of the door frame to correspondingly contact the side outer panel, and a molding device inserted and fixed in one side of the carrier.

An underrun protection device for a vehicle comprises a hybrid beam formed of a preform member and a thermoplastic formed onto the preform member, and configured to attach to a vehicle attachment element, the hybrid beam comprises the preform member defines a channel and is configured to couple with the vehicle and extend along a side of the vehicle parallel with a centerline of the vehicle, with an opening of the channel oriented away from the centerline, wherein the channel is defined by an inside surface at least partially facing away from the centerline, and an outside surface at least partially facing the centerline; and a thermoplastic beam formed of the thermoplastic and shaped to conform to the channel of the preform member, the thermoplastic beam at least partially abutting the inside surface of the channel.

A structural member for a vehicle includes an outer panel defining a U-shaped channel. The outer panel is formed from a first material. The structural member further includes a reinforcement panel defining a U-shaped channel. The reinforcement panel is formed from a second material different than the first material and is formed to attach to the outer panel. The structural member also includes an inner panel defining a U-shaped channel. The inner panel is formed from a third material different than the first and second materials and is formed to attach to the reinforcement panel such that the outer panel, reinforcement panel, and the inner panel are oriented along an axis and span an entire length of each of the U-shaped channels.
