Hybrid fillers of silicon nitride/carbon fibres (Si 3 N 4 /CFs) are performed to improve the thermal conductivities, mechanical and thermal resistance properties of the bismaleimide (BMI) composites. The thermally conductive coefficient of the Si 3 N 4 /CFs/BMI composites is improved to 1.68 W/mK with 50 wt% modified Si 3 N 4 fillers. The flexural strength and interlaminar shear strength of the composites are optimal with 10 wt% modified Si 3 N 4 fillers. The thermal resistance properties of the Si 3 N 4 /CFs/BMI composites are also improved with the addition of Si 3 N 4 fillers. Surface modification of Si 3 N 4 fillers exhibits positive effects on the thermal conductivities and mechanical properties of the Si 3 N 4 /CFs/BMI composites. POLYM.
