ABSTRACT
Bumpers play an important role in preventing the impact energy from being
transferred to the automobile and passengers. Saving the impact energy in the
bumper to be released in the environment reduces the damages of the automobile
and passengers. Therefore researchers have sought to make bumpers lighter
without sacrificing strength, ability to absorb impact, or passenger safety. This study
investigates the possibility of adding filling material between the bumper and front
car body. The experimental tests were conducted and applied on front bumper of
Fiat- Sahin vehicle.
The results showed the improvement in bumper impact resistance about 260% when
using one layer of honey comb cardboard cell and cardboard sheets as filling
materials.
