The inherently sustainable and biodegradable properties of bio composites have been a subject of interest in materials science from both ecological and environmental perspectives. The potential use of natural fiber reinforced composites in tribological applications has made it important to investigate their behavior against various types of wear. Abrasive wear is the most common type of these. This study aimed to reveal the relationship between the wear behaviors and the material structure of wool felt/epoxy composite. For this purpose, the dry sliding wear behavior of wool felt/epoxy composites was investigated with a ball-on-disc test at three different normal loads (10N, 15N and 20N) and three different sliding velocities (60, 120, 240 rpm). It was observed that the wear rate increased as the load increased, but the rotational velocity had no consistent effect on the wear rate. However, the wool felt reinforcement was found to have no effect on the wear resistance of the neat epoxy. Following wear tests conducted under various conditions, scanning electron microscope (SEM) was used to analyze the morphologies of the worn surfaces. Surface wear debris, thick plates, pellets, polymer slices were observed in local worn areas, wool fibers were broken and visible. Compared to the neat epoxy, the wool felt/epoxy composite had more flaky wear debris.
