    Abstract

    In cooperation with SKF, this PhD project focus on the improvement of the tribological performance of self-lubricating composites for dry sliding bearings. Several novel self-lubricating composites with very good performance and low production cost is developed in this research, which perform better than the composite liner used current by SKF. A deep understanding of the effect of the content of PTFE, the mechanical properties of composites and the property of various sliding counterparts on the wear mechanism is achieved. The conformational change of PTFE molecule chains are investigated and discussed. The role of the metal-F bonding on the tribological performance of the PTFE filled composites is examined in depth. Suggestions for the design of self-lubricating polymer composites are proposed.
