The objective of this work is to develop aramid pulp/carbon fiber-reinforced polybenzoxazine composites as high performance friction materials. Effects of aramid pulps and carbon fibers on thermal stability, mechanical properties, and tribological performances of the composites are investigated. Aramid pulps could enhance friction coefficient and friction stability of the composites, while thermal stability, mechanical properties, and wear resistance of the composites are improved with an addition of carbon fibers. The composites exhibit high thermal degradation and glass transition temperatures, high and stable friction coefficient, and good wear resistance. The developed polybenzoxazine composites could be applied as non-asbestos organic friction materials.
