文摘

[0/902]S and [0/452/0/−452]S G/E laminates were produced by vacuum resin infusion. Using different process parameters, different void contents were obtained. Fatigue damage initiation, evolution and stiffness drop were deeply affected by voids. A larger influence of voids was found for the cross-ply laminates. Both void content and size contributed to decreasing the fatigue performances.
