Description
Summary:Polyetherimide (PEI) is a high performance thermoplastic polymide with good thermal, mechanical and electrical (insulating) properties with the added advantage of easy processability. Hence, for tribological studies, a short-glass-fibre-reinforced and internally solid lubricated composite of PEI was selected. Its friction and wear properties (in dry conditions) were tested for various experimental parameters such as load, sliding distance, speed and fibre orientation against a mild steel counterface. A very good combination of friction and wear properties was displayed by the composite. Its performance was compared with that of other PEI composites and bulk PEI for a better understanding of the role of fillers. Also, scanning electron microscopy studies were carried out on the worn pin and disc surfaces.
