Abstract

The design of highly dynamically loaded lightweight components with new types of textile reinforcement requires reliable knowledge of the deformation and failure behavior depending on the loading speed and the fatigue loading history. A servohydraulic high speed test unit in combination with a high-speed camera was used to determine the strain rate de-pendent material properties of non-crimp glass fiber reinforced composites with fatigue related damage under tensile loading. The deformation and failure behavior of these composites was examined in ex-tensive highly dynamic tensile loading tests. The increase of direction related stiffnesses and strengths at increasing strain rates was successfully quantified on the one hand and the influence of fatigue related damage to subsequent highly dynamic tensile load-ing was basically characterized. For the mathemati-cal description of the strain rate dependent material behavior of textile reinforced composites with de-fects resulting from previously fatigue an additive model in the sense of continuum damage mechanics was introduced and validated.
