摘要

Generally brake pads are manufacturing by use of asbestos materials, that materials are chemically harmful and toxic nature to affect the human health. The present investigation is to fabricates polypropylene composites with mixing constant volume [5 vol.%] of alumina nano particles and different volume percentages [0%, 5%, 10% & 15%] of basalt Fiber by hand layup compression technique. The wear characteristics of polypropylene matrix composites were tested by dry sliding condition. The test was carried out pin on disc apparatus, configured with hardened steel counter-face at elevated temperature. The load was applied 10 N to 30 N with the interval of 10 N and varying of sliding speed 300 rpm to 900 rpm with the interval of 300 rpm for the time period of 0-180 sec. The wear rate was decreases with addition of alumina nano particle and the frictional force was increases due to basalt Fiber content present in the composites. The co-efficient of friction was increases 0.1 to 0.66 under normal loading condition.
