抄録

Mode II fatigue delamination growth behaviors of toughened unidirectional CF/Epoxy laminates, T800H/3900-2 and IM-600/#134, were characterized. Both G<SUB>IImax</SUB>-constant tests and G<SUB>IImax</SUB>-shedding tests were conducted by a test system based on CSD measurement. As the results, in the initial period of the delamination growth there exist transient behaviors of the delamination growth rate. The index number of power law of two kinds of toughened CFRP were smaller than that of the untoughened CFRP, T800H/3631. But for the threshold behavior, there was almost no improvement with the toughening. The difference of the mode II delamination behaviors between the toughened CFRP and the untoughened CFRP is related to the thickness of their interlamination and the size of the plastic zone. Moreover, the influence of stress ratio was evaluated by applying equivalent energy release rate range. Discussion are also made on the delamination growth onset determination.
