abstract Novel textile reinforced composites have outstanding specific mechanical properties and superb energy absorption capabilities, which makes them excellent candidates for impact and crash resistant elements. Despite their distinguished properties, textile reinforced composites have not experienced a broad application yet, mainly due to the lack of realistic failure models, that account for the complex mechanisms involved in the dynamic failure of such materials. In developing appropriate simulation and failure models for textile composites under dynamic loading, basic experimental investigations are required to understand the complex structural and failure mechanisms. The performed experiments provide the necessary knowledge to develop adapted material models, which take into account the textile reinforcement structure and serve for the simulation of the impact and crash behaviour with the help of numerical programs.
