摘要：
Two self lubricating fabric composites with different twist directions of polytetrafluoroethylene(PTFE)-Nomex yarns were prepared by dip-coating of the PTFE-Nomex/Nomex fabric in a mixed resin of high-temperature resistance. The tribological performance of the resulting fabric composites at different temperatures was evaluated, by which the influence of yarn twisting direction on the tribological properties was studied. The results show that the mechanical properties of S-twist PTEF-Nomex/Nomex fabric are slightly better than those of Z-twist PTEF-Nomex/Nomex fabric, with the tensile strength and elongation at break of both composites higher than 25 MPa and 75%, respectively; the wear loss of S-twist PTEF-Nomex/Nomex fabric composite is little affected by temperature, whereas the wear loss of Z-twist PTEF-Nomex/Nomex fabric composite increases with a rise in temperature. At all temperatures investigated, the S-twist PTEF-Nomex/Nomex fabric composite shows more favorable anti-wear property; although the friction coefficient of both composites is relatively stable with the change of temperature, the friction coefficient of S-twist PTEF-Nomex/Nomex fabric composite is smaller, at the same temperature, than that of Z-twist PTEF-Nomex/Nomex fabric composite. Wear mechanism analysis indicates that temperature has a significant impact on the wear behaviors of the fabric composites. Besides, it is proposed that the improved mechanical properties and the uniform lubricating films contribute together to the reinforced tribological properties of the S-twist PTEF-Nomex/Nomex fabric composite. © 2019, Editorial Board of Polymer Materials Science & Engineering.
