Investigation in to Wear behavior of coir Fiber Reinforced Epoxy Composites with the Taguchi Method

In present investigation the wear behavior of treated and untreated coir dust filled epoxy resin matrix composites were studied. The effect of treated and un treated coir dust concentration (10%, 20% and 30%), varying loads (10, 20 and 30N) and varying velocities (300, 400 and 500) on the abrasive wear rate of composite has been analyzed. The abrasive wear property of the composite is examined on a pinon-disc machine against 400μm grit size abrasive paper with test. To minimize the experimental time and cost of investment taguchi method model L9 is selected. However, it is found that the treated fiber composite shows better wear resistance than the untreated fiber composites. Abrasive wear rate is decreased with increasing the coir dust amount. As the load increase the wear rate increases also observed similar trend also observed in velocities also.
