Crash box is one of the passive safety features that serve to absorb energy. Usually, crash box is made of metal material such as aluminum or steel. Lately, composite materials have become popular because of their superior properties. Composite is an option because it has a low mass, but has high strength. The combination of composites and metals is an alternative solution to improve the ability of the crash box. The combination of these two materials is called a hybrid crash box. To find out and study the feasibility of a circular crash box cross-section crash with the effect of the manufacturing process on the manufacturing process, in-depth research and study need to be done. In this research, a circular section crash box experiment will be conducted with aluminum, composite, and hybrid materials. Composite material to be used Glass Fiber Reinforced Polymer (GFRP) Parametric studies were carried out to determine the energy absorption characteristics, which include the effect of fiber orientation, number of layers of fiber, and the failure mechanism of a circular cross-section crash box with glass fiber and hybrid composite materials. The results of this study can be utilized for the advancement of energy absorbing components of road and air transportation.
