Dry sliding wear behavior of SiC/Al2O3 filled jute/epoxy composites
Highlights ► Jute composites are detrimental to wear at high loads and velocities. ► Effect of ceramic fillers on wear of jute composites is examined. ► Ceramic fillers in jute composites improve their resistance to wear. ► Al2O3 filled jute composites demonstrate their better wear resistance.
Abstract The effect of ceramic fillers like SiC and Al2O3 on wear behavior of jute/epoxy composite has been experimentally investigated. The laminates of jute/epoxy composites with fillers in 5%, 10% and 15% based on weight of resin were prepared using hand layup technique. The dry sliding wear tests were conducted using pin-on-disc wear test machine. Tests were conducted for a constant sliding distance of 1800m and a track radius of 50mm. For each composition, wear tests were conducted for different sliding velocities (3m/s, 4.5m/s and 6m/s) by applying normal loads of 30N, 40N and 50N. The wear loss and coefficient of friction were plotted against the normal load and sliding velocity for composites with both types of fillers. The results reveal that incorporation of fillers leads to significant improvement in the wear resistance of jute/epoxy composite. It is observed that Al2O3 filled composite has better wear resistant than SiC filled. Worn surfaces of selected samples were sputter coated with a thin layer of gold and then subjected to scanning electron microscopy to analyze the mechanism of wear.
