Abstract
Studied herein is an experimental study on the collision between two steel girders using laminated fiber reinforced rubbers. The steel girder has 1000mm long, 200mm wide and 200mm high and the collision velocity ranges from 0.25m/sec to 2.00m/sec on 5 stages. In this experiment, a rubber or a few kinds of laminated fiber reinforced rubbers (LFRR) are equipped as a shock absorber and the energy absorption and the impact force during the collision are investigated. The following results are obtained from this study. The usual rubber and the LFRR are similar in the energy absorption during the collision however, the LFRR reduces the impact force better than the usual rubber when the laminated fibers break.
