  • Plastic composite bumper beam for vehicle
    Patent number: 8376426
    Abstract: Disclosed is a plastic composite bumper beam for a vehicle, which can achieve a reduction in weight and cost and has improved mechanical properties, structural strength, and crash performance, load introduction, load distribution to the fixation points, thus reducing the thickness of the bumper, compared to conventional plastic composite bumper beams. Therefore, it is possible to improve the degree of freedom in design and the marketability due to the reduction in thickness of the bumper. More specifically, the plastic composite bumper beam for a vehicle includes a bumper beam body having the shape of a bumper beam and formed of a fiber-reinforced plastic composite material; and an insert reinforcing member inserted into the bumper beam body, the insert reinforcing member having a loop shape and disposed in the longitudinal direction of the bumper beam body.
