A vehicle body structure includes a reinforcing material layer formed of a fiber reinforced resin and a vehicle skeleton member having a closed sectional structure formed of metal. The reinforcing material layer is bonded to a surface of the vehicle skeleton member having a recessed portion recessed toward an inside of the closed sectional structure. An adhesive is disposed at least between the recessed portion and the reinforcing material layer.

A liftgate assembly having finished show surfaces, and process of manufacturing same. The liftgate assembly includes local reinforcements that are overmolded to first reinforcements, and the first reinforcements are infrared welding to a first panel. Second and third reinforcements are also infrared welded to the first panel. To infrared weld the respective reinforcements to the first panel in predetermined locations with respect to the first panel, nesting structures are provided to hold the respective reinforcements and first panel. At least one infrared heating fixture heats various predetermined surfaces on the reinforcements and first panel, and the parts are then pressed together for joining the predetermined surfaces of the respective parts together. The process is repeated, if needed, until all of the reinforcements are infrared welded to the first panel. Outer panels are bonded to the second and third reinforcements.

A frame-channel-integrated door of a metal-plastic composite material in which a frame channel provided between an external panel and an internal panel is integrally joined to a panel made of plastic material, includes a first panel made of plastic material and positioned on one of an external surface and an internal surface of a vehicle door, a second panel made of metal material and positioned on another one of the external surface and the internal surface of the vehicle door, and a frame channel attached to an internal surface of the first panel, wherein the frame channel is coupled to the outside of a glass run, and the second panel is joined to the outside of the frame channel.

A rigidity-improved vehicle panel door includes an external panel positioned, toward the outside of a vehicle, in a door of the vehicle, an internal panel, an external edge portion of the internal panel being joined to the external panel, and the internal panel being positioned, toward the interior of the vehicle, in the door, and a rigid structure in which a plurality of support members disposed in a longitudinal direction of the vehicle are coupled to a plurality of reinforcement members to form the shape of a quadrangle, the plurality of reinforcement members being provided on a front end portion of the door and a rear end portion of the door.

A hemming structure may include a door, in which the door has an internal panel and an external panel made of different materials, the hemming structure being configured such that each of the internal panel and the external panel is provided with a contact area with end portions of the internal panel and the external panel contacting with each other at the contact area, wherein the contact area includes a first contact area with a sealer applied onto a contact surface between the internal panel and the external panel, and a second contact area extending from the first contact area and being bent to be brought into contact with the internal panel at the first contact area, and the second contact area is provided with a bonding portion at which the internal panel and the external panel are mechanically bonded to each other.

Present disclosure discloses a reinforcement member (10) for a vehicle. The member includes a first component (1) made of steel and a second component (2) secured to a portion of the first component. The second component is made of a reinforced polymer. The reinforcement member with the combination of the second component and the first component is configured to absorb impact energy. The reinforcement member (10) of the present disclosure is lighter in weight unlike the conventional reinforcement members and is structured to absorb/attenuate significantly impact higher energy than the conventional beams.

A carrier of a carrier module for a motor vehicle door assembly and method of manufacture thereof is provided. The carrier has a body with opposite wet and dry sides bounded by an outer periphery configured for attachment to an inner panel of the motor vehicle door assembly. The body is made of a recyclable, environmentally sustainable natural fibrous material.

A lightweight and simplified vehicle door assembly is provided with four main components, an upper frame positioned about the window, an inner frame structure, an outer body panel, and a composite reinforcement component. The composite reinforcement component provides an all-in-one solution for a side impact cross beam, as well as an upper door reinforcement, a front door pillar reinforcement, and a rear door pillar reinforcement. The composite reinforcement component acts to reinforce the overall door structure, offers resistance to a side impact that limits the intrusion into the passenger compartment, and offers resistance to a frontal impact by maintaining the spacing between the vehicle A and B pillars (for a front door) and pillar C and D for a back door. A coupe vehicle door in which there is no window frame may be reinforced with the composite reinforcement component. The composite reinforcement component may have continuous or chopped fibers.

A vehicle tailgate structure including a first panel portion including a composite material and a second panel portion overmolded onto the first panel portion, the first and second panel portions forming together a body portion, a transverse beam and side beams connecting the transverse beam to the body portion, wherein the transverse beam includes a hinge attachment portion configured to receive a hinge attachment part, wherein the first panel portion has a bent strip in the transverse beam, and wherein the bent strip is raised with respect to a remaining portion of the first panel portion.

A door of a vehicle may include a first door module forming a door skeleton; a second door module coupled with the first door module and forming a door window; and a door frame coupled to the first door module and engaged with the second door module; wherein the second door module may include a relatively lightweight material as compared to the first door module, reducing weight and cost of the door for a vehicle.
