Development of Automobile Bumper Beam Using Hybrid Process 2011-01-0006
Recently, application of light-weight materials is increasing in the automobile industry to improve the fuel efficiency. The hybrid bumper beam consisted of the steel and plastic (GMT) is manufactured. If this process is introduced on automobile bumper beam, the mass of bumper beam can be dramatically reduced. In order to satisfy the regulation (FMVSS PART 581, IIHS), executed FEM (finite element method) analysis, low speed and high speed crash have been demonstrated. As a result, it was achieved mass reduction of 17%, while performance is maintained.
