Abstract

Composites are two-phase materials. They have hard and stiff reinforcements incorporated in metal/ceramic
matrices. Composites have superior mechanical properties, which contribute toward the enhancement in their
tribological performance. Their enhanced wear and friction properties are attractive in applications such as
automobile, aerospace, biomedical, and sports utilities. Wear of composites is determined by the underlying
operating wear mechanisms. Friction of composites may/may not follow similar dependence on applied
parameters of speeds and loads, as that of wear. In this paper, examples of tribological performance of advanced
composites taken from various research works are presented. The discussion presented in the paper provides an
overall understanding of the tribological response of representative composite systems.
