Abstract	The creep behaviors of carbon fiber (CF)/epoxy resin thermosetting composites and CNTs/CF/epoxy resin composites were tested and analyzed at different stresses, orientations of fiber, temperatures and humidities. The creep exhibits only two stages-primary creep and steady-state creep. The effects of creep stress, creep time, and humidity on the creep of composites that contain various proportion of CNTs were investigated at various temperatures. Creep strain is believed to increase with applied stress, creep time, humidity, temperature and degree of the angle 0 between the orientation of fiber and the direction of the applied stress. Moreover, the test results of creep strain of CF/epoxy resin composites and CNTs/CF/epoxy resin composites tested under various conditions can be smoothly fitted by the fitting curves of Findley power law. Finally, the test results also indicate that mechanical strength increase with the amount of CNTs added to the composites. Different coefficients of expansion of the matrix, fiber and CNTs, are such that overexpansion of the matrix at high temperature results in cracking in it. An SEM image of the fracture surface reveals debonding and the pulling out of longitudinal fibers because of poor interfacial bonding between fiber and matrix, which reduce overall strength. © 2012 by Asian-Australian Association for Composite Materials (AACM).
