The tribological properties of polybenzimidazole composites filled with graphite (Gra), boron naitride (BN), glass fiber (GF) and carbon fiber (CF) were discussed in this study. The results were summarized as follows. 1) The average frictional coefficient μ of PBI composite with Gra, BN and CF was smaller than that of unfilled PBI (100% pure PBI). 2) The wear rates (Vs) of PBI composites filled with GF, CF Gra, BN and CF were smaller than the wear rate of unfilled PBI. Vs of Gra, BN, CF filled PBI composite were 0.09mm^3/kgf・km, was smaller than that of unfilled PBI, GF filled PBI and CF filled PBI. respectively. 3) The wear rates of unfilled PBI, GF filled PBI, CF filled PBI and Gra, BN, CF filled PBI composites were incerased with the incerasing frictional speed and surrounding temperature.
