The effect of sliding distance at different temperatures on the tribological properties of a palm kernel activated carbon-epoxy composite

摘要

The aim of this study is to investigate the effect of sliding distance and temperature on the tribological properties of a palm kernel activated carbon-epoxy (PKAC-E) composite. All specimens were formed into 10-mm diameter pins of 30-mm length. Tribological tests were conducted using a pin-on-disc tribometer. The results show that there is no significant effect on the coefficient of friction (COF) with the sliding distance, although the wear rate is slightly increased. However, when the operating temperature exceeds a critical limit, both the COF and wear rate rapidly increase with sliding distance. As compared with synthetic and other agricultural waste-based polymeric composite, PKAC-E is considered as one of the most potential self-lubricating materials at operating temperature below 90 degrees C.
