Fatigue of textile composites

The chapter gives an overview on a broad range of composite reinforcements, namely: non-crimp fabrics (considered as a peculiar architecture among the woven reinforcements), 2D and 3D woven textiles. Those were selected to cover general phenomena and features of the fatigue mechanical behaviour of textile composites. For each of the mentioned families of reinforcement, a dedicated section provides an overview on the effect of the peculiar features of the reinforcement on the fatigue performance and fatigue damage, and, if available, on the correlation of quasi-static and fatigue damage. The section dedicated to non-crimp fabric composites distinguishes the behaviour of carbon and glass fibre as well as the stitching scheme. The section covering 2D textile composites highlights the fatigue behaviour of a glass plain weave-reinforced epoxy, and the fatigue notch sensitivity of a carbon plain weave reinforced epoxy. Finally, a 3D orthogonal weave glass reinforced epoxy is considered to detail and compare the quasi-static and fatigue damage evolution.
