The new material fender that was made with TPE (Thermo Plastic Elastomer) is excellent in restoration, and it has good compression characteristic for energy absorber. We are doing the research that checks the characteristic of the new material fender for ship collision by the model test and numerical analysis. This report studied the characteristic of the new material fender for ship's head-on collision by using the PEL-fender and urethane foam as the model. When rearranging the results, (1) When the entrance angle of the bow becomes large, the slope of a reaction force-bow penetration curve becomes steep. At this time, the change rate of the slope becomes steep with the increase of the entrance angle. Although reaction force differs as for PEL-fender and urethane foam, these trends resemble. (2) The reaction force of the dynamic test is bigger than the reaction force of the static test. (3) Absorbing effciency and energy absorbing factor do not change by the bow measure.
