Abstract
Safety in driving is certainly an important aspect. One of the efforts to maintain safety in driving is to have a solid vehicle structure, including a crash box. The crash box is thin-walled tube used as an energy absorber during the impact. The structure requires strong and lightweight materials; thus, the application of composite is often considered. This study investigated the energy absorption of the crash box made of carbon Pyrofil- HR40. The quasi-static analysis was performed by using the finite element software of LS- DYNA. The effects of the geometry and thickness of the crash box on the specific energy absorption were studied. It was found that the same diameter and thickness circular tubes had larger specific energy absorption with value 30.842 kJ/kg than that of the square with value 20.342 kJ/kg.
