ResumoPolyetherimide, commercially known as ULTEM resin, is one of the newest high performance engineering thermoplastics. It has a unique combination of thermal, mechanical and electrical (insulating) properties. Its glass-fibre-reinforced (20%) composite has still better mechanical properties and has been studied in the present work to evaluate its potential as a tribological material. Tribological studies were carried out on a tri-pin-ondisc machine against mild steel as a counterface at various loads, surface roughnesses and speeds. The specific wear rate was found to be comparable with that of commercially available bearing materials. However, the friction coefficient was high and slightly unsteady. Scanning electron microscopy studies were done to investigate the wear mechanisms.
