The artificial accelerated cyclic hygrothermal aging test was conducted on T700/TDE86 carbon fiber reinforced resin matrix composites, and the effects of different cyclic hygrothermal aging days on interlaminar fracture toughness of composites with open type (mode Ⅰ) and slip type (mode Ⅱ) were investigated. The results show that the model Ⅰ interlaminar fracture toughness of composite after cyclic hygrothermal aging exists an obvious R curve, the initial extend energy release rate (GIC,init) and the propagational extend energy release rate (GIC,prop) of composite are improved remarkably with the increase of cyclic hygrothermal aging days. The model Ⅱ interlaminar fracture toughness of composite appears a trapezoidal descent with the increase of cyclic hygrothermal aging days, and the decline is the largest at the early stage of cyclic hygrothermal aging and the largest descent is 21.68%.
