For a reliable structural design of security-relevant, high-dynamically loaded light weight structures, the knowledge of the strain-rate-dependent material and damage behaviour, material properties, and validated material models have to be provided. For this purpose, various material tests at different strain rates have been performed on composites with a novel 3D-reinforced glass-fibre multilayered flat-bed weft-knitted fabric reinforcement by using a servohydraulic high-speed testing unit in combination with specially adapted clamping de vices. The highly dynamic material tests served to develop adequate material models in the classical sense of continuum damage mechanics and to determine the associated model parameters.
