Vehicle crash boxes are components mounted on a vehicle's chassis that absorb the energy generated during a collision. These boxes must possess high energy absorption capacity to effectively maintain the integrity of the vehicle. A higher energy absorption value facilitates better preservation of the vehicle's integrity, which is crucial for ensuring the safety of the occupants during a crash. Additionally, the extra weight added by crash boxes is a significant issue as it increases fuel consumption, a major problem for vehicles. To address this, efforts are being made to produce crash boxes from lighter materials. Composite materials emerge as suitable candidates due to their combination of lightness and strength. Furthermore, in the literature, energy absorption is generally calculated after applying compressive forces to crash boxes up to a certain length. The most suitable crash box is selected using this method. In this study, energy absorption values up to the maximum peak force (PF EA) were compared with semi-static tests conducted to a specific distance (50 mm). Epoxy resin matrix composite materials were produced with fiber reinforcements of glass fiber, aramid fiber, and carbon fiber. The vacuum infusion method was used to ensure uniform and consistent distribution of the epoxy. As a result, the best performance up to 50 mm was achieved with the carbon fiber sample, while the lowest performance was observed with the aramid fiber sample. No significant change in the energy absorption trend was observed up to the maximum peak force. The carbon fiber sample provided the best results, while the aramid fiber sample yielded the poorest results.
