A vehicle bumper is provided integrally to include metal beam-extension portions on both right-and-left end sides of a metal bumper-beam portion. In this vehicle bumper, the bumper-beam portion and the beam-extension portion include a vertical wall portion, an upper wall portion and a lower wall portion, and a resin reinforcing rib is joined to inner surfaces of a void formed of each of the wall portions. In addition, in this vehicle bumper, an extension dimension of the upper wall portion and the lower wall portion of the beam-extension portion is larger than an extension dimension of the upper wall portion and the lower wall portion in the bumper-beam portion, the resin reinforcing rib in the beam-extension portion is joined to the vertical wall portion, the upper wall portion, and the lower wall portion of the beam-extension portion; and the stiffness of the bumper-beam portion is higher than the stiffness of the beam-extension portion.

The present disclosure discloses a bumper beam for a motor vehicle including a center portion free of mobility-specificity and side portions that may be altered according to design and specification of the mobility to secure collision performance so that the bumper back beam of which collision performance is secured and which satisfies various mobilities may be flexibly applied. Accordingly, it is possible to configure the back beam satisfying various mobilities based on a standardized model to secure collision performance so that manufacturing cost is reduced by assembling and producing the back beams with minimum molds.

A bumper for a vehicle includes a bumper crossbeam and two crash boxes extending away from a back of the bumper crossbeam. A one-piece blank made of fiber-reinforced sheet material extends from a wall section of the bumper crossbeam connecting the crash boxes, right into the crash boxes.

A hybrid bumper assembly for a vehicle includes a steel reinforcement beam and aluminum crush cans attached to end portions of the steel reinforcement beam. The reinforcement beam has a multi-tubular shape that is formed by a high-strength steel sheet that is roll formed to provide at least two tubular portions. A crush can has an interfacing portion that is coupled to an end portion of the reinforcement beam. The end portions of the reinforcement beam and the interfacing portion of the crush cans may be configured to attach together using a select joining technology in a manner that minimizes or eliminates bimetallic or galvanic corrosion between the reinforcement beam and the crush cans.

A body rear structure of a battery electric motor vehicle includes a rear bottom part. A bottom side of the body rear structure has at least one plastics sacrificial part which is fastened to the rear bottom part and extends downwards away from the rear bottom part and which is so configured that it forms a deformation element in the event of mechanical contact with a wheel stop at an electric charging station.

A process for the production of manufactured articles in composite material comprises at least one supply phase of a plurality of layers and at least one coupling phase of the layers. The coupling phase comprises at least one step of arrangement of the layers overlapped onto each other to create at least one stratified body. The coupling phase comprises at least one step of positioning the stratified body inside a mould. The coupling phase comprises at least one firing step of the layers positioned inside the mould. The supply phase comprises at least one supply step of at least one basic layer and at least one supply step of at least one reinforcement layer.
