Nonlinear Analysis of Friction Behavior in Glass Fiber and Organic Clay Reinforced Polyphenylene Sulphide Composites via Pin-on Disc Testing

Abstract

The goal of the current study was to determine how different operating parameters, such as load, sliding speed, and sliding distance, affected the tribological behavior of composites consisting of 40% by weight of glass fiber and Polyphenylene Sulphide (PPS) with the varying percentage by weight of Bentonite clay. The study aimed to investigate the effects of different experimental settings on two distinct results: wear and coefficient of friction. This was made possible by utilizing a Taguchi L9 orthogonal array, allowing experiments to be performed at three distinct degrees of complexity. Six material samples totaling different weight percentages of bentonite clay were the subject of this investigation, which was carried out using a pin-on-disc setup as per ASTM G99. The outcome of this investigation revealed that for the virgin sample, the coefficient of friction increases with the increase in the applied average load. Also, it was observed that the rise in the average load reduced the coefficient of friction of the samples containing the Bentonite clay. Whereas an increased proportion of clay in the composite has shown a remarkable increase in the coefficient of friction value from 1% to 5%, a further rise in the clay proportion up to 7% shows a noteworthy reduction in the coefficient of friction value.
