An innovative type of energy absorber is presented, which involves fibre-reinforced plastics as an absorbing material and which admits in comparison with a conventional metallic energy absorber a low weight and high level of integration inside an overhead stowage compartment in aircraft cabins. Test results of different fibre orientations were shown, stating that fabrics with +-45 degree ply orientation show an applicable crushing behaviour. Micrographs of the crush zone confirm the existence of a debris wedge and suggest that reinforcement stitching in thickness direction improves the crushing characteristics. Further investigations concerning the implementation in aircraft cabins will be conducted. For design purposes a numerical analysis of the process with LS-DYNA was conducted. It could be shown that post-test simulations with one parameter set for different plate thicknesses had a relatively good correlation between test results and simulation, but required the tuning of non-physical simulation parameters. This tuning renders the parameter set almost useless for different ply-orientations or material changes. Therefore experimental testing of materials and concepts is still required for developing energy-absorbing structures made of fibre-reinforced plastics.
