CF/PEEK composite plates have high delamination resistance because of the high fracture toughness of PEEK. Several studies have been conducted to obtain the delamination resistance. Few delamination micromechanisms, however, have been studied. In particular, the micromchanism compared with that of CF/Epoxy composites is important for the material designing but there are few studies about it. Thus the objective of this study is to measure the delamination resistance of that of mode I and II, considering the micromechanism in comparison with that of CF/Epoxy composites. Results of mode I and II delamination tests indicate that the fiber-resin interface debonding has an important effect on the delamination resistance of CF/PEEK. Additionally, the stick-slip phenomenon model was considered, comparing with that of the CF/Epoxy composites.
