摘要：

In the first part of this chapter, various types of advanced polymeric composites are discussed. The rest of the chapter is devoted to the tribology of such advanced composites. The tribology of two types of polymeric composites, those with thermoplastics and thermosets, are separately discussed. The literature on the progress of such composites in recent years will be reviewed and discussed in separate sections in relation to the four wear modes, i.e. adhesive, abrasive, fretting-fatigue and erosive. Systematic step by step addition of solid lubricant and reinforcement of a polymer matrix could lead to an optimal combination of friction and wear characteristics. The influence of the various operating factors is also critically examined. The wear mechanisms of fibre reinforced thermoplastic composites are discussed in detail. The influence of various additives (powdery and reinforcing) and contents on the abrasive wear performance is also discussed. The wear and appropriate mechanical-property correlations are also examined. In the case of advanced thermosetting composites tribology, carbon, graphite, glass and aramide fibre composites with unidirectional and multidirectional reinforcement are discussed. Various operational factors, environmental conditions and types of fibre–matrix combination ultimately determine the actual performance of the composite.
