Abstract: The antistatic and heat-resistant carbon fiber(CF)-aluminum nitride(AlN)/poly ether ether ketone(PEEK) composites were prepared by compression molding, in which PEEK was used as matrix resin, CF and AlN were used as fillers. The antistatic, thermal and mechanical properties of CF-AlN/PEEK composites were characterized by high resistance meter, thermal conductivity instrument, thermo-gravimetric, differential scanning calorimetry and SEM. The effect of cooling rate on properties of composites and the effect of heat post-treatment on mechanical properties were also discussed. The results show that CF-AlN/PEEK composites have better properties when the mass fractions of CF and AlN are both 10% and surface resistivity is 10⁸ Ω which improves 6 magnitude than that of PEEK. The thermal conductivity coefficient and initial decomposition temperature are 0.418 W·(m·K)^-1 and 573℃ respectively.The tensile strength increases by 40.4%. The lower the cooling rate is, the higher the melting point of composites have. Heat post-treatment could affect mechanical properties of CF-AlN/PEEK composites. Tensile strength can reach 146 MPa at 270℃ after heat treating 2 h, which indicates that processing temperature is one of the factors that influences properties of composite in process of production.
