ventional clay-filled composites increase with increase in inorganic clay content. The
specific wear rate of nanocomposites and conventional clay-filled composites with
respect to the clay content is shown in Fig. 2.4.
Dhakal et al. [19] have studied the effect of various loading levels of nanoclay rein-
