Carbon nanotubes (CNTs) possess special physical characteristics such as strength, stiffness, light weight, electrical conductivity, highly thermal conductivity and thermal stability, etc. Because of their high absolute strength and large surface area, multiwalled carbon nanotubes (MWCNTs) have high potential for improving the material properties of polymer-based composites. In this study, MWCNTs was used to reinforce epoxy/carbon fiber (CFRP) composite laminates to enhance their mechanical properties. The mechanical properties of MWCNTs / CFRP composite laminates including flexural and interlaminar shear strength (ILSS) under different thermal cycling conditions (i.e. 50, 100 and 200 times at -40 ~ 125 °C) were investigated, and the fracture surface of the specimen was also investigated using field emission scanning electron microscopy (FESEM) to determine the mechanisms of the MWCNTs in the CFRP composite laminates.
