In the current study, the effects of treating the Musa acuminata stem fiber (MASF) on the tribological performance of polyester composite were studied against polished stainless steel counterface using a computerized pin on disc (POD) machine under dry contact condition. Wear and friction characteristics of alkaline treated, silane treated and untreated MASF (MASF-AT, MASF-ST and MASF-UT) reinforced polyester composites were evaluated at different sliding sliding speed (1.5, 2.0, and 2.5 m/s), applied normal loads (15, 20, 25, and 30 N), and applied loads (30–100 N) and for a constant sliding time of 10 min under dry condition. SEM observations were performed on the worn surfaces of the composites to examine the damage features. Wear resistance, and friction coefficient results were presented against the operating parameters. The results revealed that test parameters significantly influenced the wear resistance performance of the composites. Both treated MASF-AT and MASF-ST enhanced the wear resistance and performance of polyester composites reinforced MASF showed more wear resistance about 23% - 34% compared to MASF-UT. But the friction coefficient decreased about 16% - 25 %. This was due to the better interfacial bonding between polyester-MASF offered by the treated fibres. The SEM observation made on MASF-UT worn surface showed debonding and bending of fibres, and fragmentation and deformation on the resinous regions. Furthemore, polyester composite reinforced MASF-AT and MASF-ST showed less damages compared to MASF-UT, where no sign of fibres debonding was observed..
