Abstract: In order to study the effect of carbon nanotubes (CNTs) on the anti-irradiation properties of carbon fiber/epoxy composites (CF/EP), CNTs were introduced into the CF/EP interface region (CF-CNTs/EP) by electrophoretic deposition. The composites were then subjected to γ ray irradiation (γ-CF/EP and γ-CF-CNTs/EP), and their properties such as mechanics, heat, fatigue resistance and functional group changes were analyzed. The results showed that the storage modulus, glass transition temperature, flexural strength and flexural modulus of γ-CF-CNTs/EP were higher than those of γ-CF/EP by 7.8 GPa, 4.53 ℃, 280 MPa and 19.2 GPa, respectively. The fatigue resistance of γ-CF-CNTs/EP was better than that of γ-CF/EP. The XPS test revealed no significant change in γ-CF/EP, while the internal C-C bond content of γ-CF-CNTs/EP decreased sharply by 10.88%, and C-N and C-O increased by 5.97% and 4.44%, respectively. Combined with scanning electron microscopy and crack propagation models, the microstructure and enhancement mechanisms of CNTs-reinforced composites for anti-gamma radiation are discussed. The above results confirm that the addition of CNTs into the interface region of CF/EP can effectively improve its radiation resistance.
