Abstract: The tribological properties are not intrinsic material properties; they depend on the experimental conditions. Composites that are very suitable for one type of application may not be useful for others. With this view, it was proposed to investigate the wear performance in extreme environmental conditions of some polyimide composites with proven properties in the adhesive wear mode. For this purpose the wear characteristics of ten such composites were investigated in extreme abrasive conditions under various loads. Fibre reinforcement and fillers (solid lubricants) with the exception of MoS2 affected the wear performance in an unfavourable way. The increase in wear with increasing percentage of fillers was attributed to the fact that the composites exhibited lesser ultimate tensile elongations than those of their parent polymers. The load and abrading particle size were observed to be important parameters in these studies.
