Composites of teak wood dust particles of 150 µm, 212 µm, and 300 µm sizes with 10 % weight fractions were developed by a hand moulding technique. A wooden mould was prepared for casting the composite pins of 8 mm diameters and 50 mm length. Sliding wear tests were conducted on a pin on disc friction and wear monitor. It was observed that the composite with mesh size 150 µm of teak wood dust exhibited the least wear rate. Furthermore, the lowest coefficient of friction was also seen in the composite with a 300 µm size wood dust filler. The composite with 212 µm size wood dust showed an increase in the coefficient of friction but at higher loads dropped down probably because of the formation of transfer film between the composite and the steel disc. The composites with 150 µm and 300 µm size dust particles were in close ranges of friction coefficients, i.e. 0.64 and 0.71, respectively. Thus though the coefficient of friction was high for a 150 µm size filler composite, the wear increased at a steady rate and may stabilize after running for more than a 5 km distance later. Out of the above three composites the wood dust of a 150 µm composite may thus be a better choice for frictional applications.
