Abstract : This paper presents the wear and morphological analysis of treated and untreated bio-fillers reinforced polymer composites. Four different bio-fillers viz. rice husk, groundnut shell powder, coconut shell powder and hybrid filler were used for the preparation of composites. Composites were prepared using treated and untreated bio-fillers in epoxy resin by hand lay-up method to study the wear properties of the composite. 20% volume fraction of bio-fillers was taken in epoxy resin. Bio-fillers are treated by malic acid. The test specimens were cut as per ASTM standard. Then tests were conducted on pin-on-disc apparatus to evaluate wear characteristics of treated and untreated bio-filler reinforced epoxy composites. Load, sliding velocity, sliding distance are taken as test parameters. After wear test, the surface morphology of test specimens were examined by scanning electron microscopy. Test results exhibited significant improvement in wear resistance of treated hybrid bio-filler composite.
