Abstract

The car crash accidents in low speed occurs most frequently. Damage on a conventional bumper after the car accident causes the bumper to get fixed most of time. This study shows how a gas tube bumper reduces a damageability and increase repairability after the car accidents. The 15 km/h 40% offset front and rear crash test recommended by RCAR (Research council for automobile repairs) standard was performed and evaluated damages on the gas tube bumper by the pendulum impact tester. In this study, the gas tube bumper reduces damageability and increases repairability after car crash accidents. In addition, car frame design to apply the gas tube bumper may consider to be changed.
