Abstract
The fundamental mechanical responses of woven CFRP (carbon fibre-reinforced plastics) test coupons subjected to static and fatigue loading were extensively carried out and results are presented in this paper. These results were then used in the development of a generalized cumulative damage model to predict static and fatigue response of a woven CFRP beam structure with an I-shaped cross section. The damage model was then applied to the beam under four-point bending to simulate the progression of failure. The results of the static response, fatigue response, fatigue life and stiffness decay predictions were compared with the experimental data. Good correlations between predicted and experimental results provide the necessary confidence in using the proposed approach.
