Rare earth (RE) La modification and air-oxidation methods were used to improve the interfacial adhesion of the carbon fibre reinforced polyimide (CF/PI) composite. The interfacial characteristics of composites reinforced by carbon fibres, treated with different surface modification methods, were investigated comparatively. Results showed that both RE modification and air-oxidation method improved the adhesion between the reinforcement and matrix, and that the RE modification method was superior to the air-oxidation method. For the CF/PI composite, optimum interfacial adhesion was obtained at 0.3 wt. % of La concentration. The fracture surfaces of samples were investigated by scanning electronic microscopy (SEM) to analyse the effects of various surface treatment methods.
