A BUMPER BACK BEAM BEING EQUIPPED WITH A FIBER COMPOSITE REINFORMING MATARIAL WITH HOLLOW SECTION INSIDE AND A BUMPER HAVING THE SAME

摘要

The present invention relates to a bumper back beam being equipped with a fiber composite reinforcing material with hollow section inside and a bumper having the same. The bumper back beam comprise a body formed with a synthetic resin, and a fiber composite reinforcing material with hollow section that is fastened inside the body, wherein the bumper back beam, as being built inside a bumper cover, reduces impact coming in from outside. A bumper back beam according to the present invention comprised as described above has high reliability, by having excellent ability to absorb impact energy because cracks almost do not occur during collision since it not only provides satisfactory strength and stiffness but also has high elongation with synthetic resin and fiber composite reinforcing materials generating synergies, and especially by having excellent impact resistance since fiber composite reinforcing materials take the shape of a hollow section.
