WebNov 14, 2000 · After same process are repeated on paper and polyester-cloth, we get that the friction coefficient of the robot on paper is 0.26 [19], and the friction coefficient on … 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]. WebPET is an unreinforced, semi-crystalline thermoplastic polyester based on polyethylene terephthalate. It is characterized as having the best dimensional stability coupled with excellent wear resistance, a low coefficient of friction, high strength, and resistance to moderately acidic solutions. PET's properties make it especially suitable for ... how to cuddle with your dog
