Unidirectional CFRP has superior in-plane mechanical properties. Its low delamination resistance, however, is a week point. Thus the delamination strength has been evaluated based on the fracture mechanics as delamination resistance or delamination fracture toughness in these days. In the previous paper, the authors have shown the effects of loading rate and load holding on the delamination resistance and the occurrence of stick-slip phenomena. In this paper, the effect of load holding was examined in detail by using a scanning acoustic microscope and the effect of stacking sequence of 0° laminae on the delamination resistance was evaluated by conducting mode I delamination tests on two types of stacking sequence. Based on these results, the stick-slip phenomena during the load holding was explained by heterogeneous crack growth with visco-elasticity in the resin rich region and the micromechanism of delamination between 0° laminae of the multidirectional laminates was proved to be the same as the unidirectional reinforced lamina except for the effect of residual stress caused by curing.
