Abstract

Abstract : This study evaluates the influence of independent parameters such as sliding velocity ( A ), normal load ( B ), filler content ( C ), and sliding distance ( D ) on wear performance of potassium-titanate-whiskers (PTW) reinforced epoxy composites using a statistical approach. The PTW were reinforced in epoxy resin to prepare whisker reinforced composites of different compositions using vacuum-assisted casting technique. Dry sliding wear tests were conducted using a standard pin on disc test setup following a well planned experimental schedule based on Taguchi's orthogonal arrays. With the signal-to-noise ( S / N ) ratio and analysis of variance (ANOVA) optimal combination of parameters to minimize the wear rate was determined. It was found that inclusion of PTW has greatly improved the wear resistance property of the composites. Normal load was found to be the most significant factor affecting the wear rate followed by ( C ), ( D ), and ( A ). Interaction effects of various control parameters were less significant on wear rate of composites.
