摘要
PURPOSE: A bumper back beam with a fiber complex reinforcing material having a hollow cross section and a bumper including the same are provided to obtain excellent efficiency for absorbing the collision energy because a crack is not generated in collision by the high elongation ratio and to improve the impact resistance by forming the fiber complex reinforcing material in a hollow cross section. CONSTITUTION: A bumper back beam with a fiber complex reinforcing material having a hollow cross section comprises a body (33) and the fiber complex reinforcing material (35). The body is molded by the synthetic resin. The fiber complex reinforcing material is fixed in the body and has the hollow cross section.
