Abstract
The friction and wear behaviour of polytetrafluoroethylene (PTFE)-based composites incorporating various fillers was determined under a constant load and at various sliding speeds when composite pins were rubbed against a steel disk. Factors influencing the wear-reducing mechanism of the fillers were studied. The friction of PTFE-based composites was generally independent of the type of filler. Fibre and particle fillers of suitable size were more effective than lamellar solid lubricants and very small hard particles. The load-supporting action and the prevention of large-scale destruction of the banded structure of the PTFE matrix at frictional surfaces contribute to the wear-reducing action of the fillers. The effects of the material and the shape and size of the fillers on the wear of composites are discussed. The load-supporting action of the fillers is discussed theoretically.
