Experimental analysis and modelling of fatigue behaviour of thick woven laminated composites

Abstract : The objective of this work was to analyse the fatigue behaviour and the damage development in unidirectional and angle-ply 2/2 twill weave T800 carbon/epoxy woven fabric composite laminates. Fatigue tensile-tensile tests were performed and internal damage has been observed by using camera and optical microscope during testing. The experimental results show that the damage evolution can be characterized by two or three stages according to the 0° ply and angle-ply laminates respectively. An original fatigue criterion for onset delamination during fatigue loading of angle-ply laminates has been proposed. Validation of fatigue model was made with tensile fatigue tests performed on angle-ply textile laminates with drilled circular hole. Further numerical predictions are in good agreement with experimental results.
