Sliding Wear Behavior of Bio Waste Reinforced Polymer Composite

Abstract

Natural fiber like chicken feather fibers are used as reinforcement in epoxy and polyester matrix composites were prepared. Wear and friction measurement on the short feather fiber reinforced composites have been performed at different loads for different rotational speed of disc. It has been found that the addition of 20% short feather fiber improved the wear resistance than that of pure matrix (epoxy & polyester).Coefficient of friction increased with increase of fiber content and decreased with increase of load. The examination of the worn surfaces of the composites by scanning electron microscopy (SEM) showed that the plastic deformation, plowing and cutting were the main wear mechanisms of the composite and there existed the strain fatigue wear and the abrasive wear features for the composites containing the feather fibers without surface modification and at the higher normal load.
