Crash absorbers made of carbon fibre-reinforced plastics (CFRP) become more and more popular to reduce mass in the front structure of cars. One open question in this issue is the correct layup, which specifies the fibre orientation, in order to obtain high specific energy absorption. Within the research, a first test series investigates crash absorbers with a fibre orientation in axial and circumferential direction and an orientation of ±45°. Based on these first experimental studies an optimisation of the layup results in a crash absorber made of CFRP with a significant higher specific energy absorption than a comparable crash absorber made of aluminium.
