Abstract
This study explores the impact of nanofillers on the wear and frictional characteristics of Cellulosic fibre-reinforced composites. With increasing demand for lightweight and durable materials in various industries, understanding the effects of nanofillers on composite performance is crucial. In this research, pin-on-disc trials were conducted under applied loads ranging from 80 N to 140 N, maintaining a constant 50% fibre volume fraction, a sliding distance of 3000 m, and a velocity of 1 m/s. The incorporation of 5 phr graphite powder was systematically investigated, compared to a graphite-absent control group, to elucidate the nanofiller's influence. Experimental results revealed a notable decrease in the Coefficient of Friction (COF) by 2.63 % to 9.09 % across different applied loads. Moreover, the Specific Wear Rate (SWR) exhibited a significant reduction at all loads, with the most substantial decrease of 61.45 % observed at 80 N. SEM analysis provided further insights, indicating a shift in wear mechanisms towards less damaging interactions. These findings highlight the potential of these composites for high-stress tribological applications in industries.
