WebThe coefficient of friction for PA/steel contacts is reported to be generally below 0.8, but also extreme values of 2.0 were observed by Watanabe et al. [10]. Also, a discrepancy in the friction behaviour was observed; sometimes the coefficient of friction increased with increasing load [8,12,13], but sometimes it decreased with increasing load [7,14]. WebApr 7, 2024 · A coefficient of friction equation can also be known as the coefficient of friction formula. It is clear from equation (3) that friction causes force to be directly proportional to the friction coefficient. It stands to reason that if the coefficient of friction is greater, then the force of friction will also be greater. WebPET is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate.
