Taguchi Approach for Characterization of Three-Body Abrasive Wear Behavior of Granite Epoxy Composite with and Without SiC Filler

Abstract

The Granite-Epoxy (G-E) composites with Silicon carbide (SiC) and without Silicon carbide filler were prepared using the hand lay-up technique. Three-body abrasive wear tests with different loads/abrading distances were performed at room temperature by using a rubber wheel abrasion apparatus. The results showed that among the filled Epoxy composites tested, 20 wt. % granite and 10% SiC filled epoxy composites showed a better result. The systematic experimentation leads to identification of significant process parameters and material variables that predominantly influenced the specific wear rate. It is evident from Taguchi wear analysis that load plays a significant role followed by abrading distance, and material composition. Finally, the worn surfaces were examined using Scanning Electron Microscopy (SEM) to identify the various wear mechanisms.
