Abstract
The chemistry and technology of high temperature plastics is outlined and the development of filled compositions for use as bearing materials is discussed with reference to their friction and wear characteristics, physical properties and fabrication problems. The development of a journal bearing lined with a polyphenylene sulphide-based composition is described and a comparison made with a commercially available epoxy-based material in tests covering a wide range of temperatures, loads and sliding speeds. The results, which are discussed in terms of wear mechanisms, indicate that high temperature plastics could offer a significant improvement over conventional polymers under conditions where bearing surface temperatures in excess of 120°C are likely to be encountered under dry or poor lubrication conditions.
