The highest and lowest trace width for the pristine Epoxy resin is 50 and 25.35 μm correspondingly. In the case of, 5 wt.% of organically modified Monmorillonite nanoclay (oMMT) filled Epoxy nanocomposite, the width of the trace is 27.69–18.46 μm respectively. It was accomplished from the width of the trace that organically modified Monmorillonite nanoclay (oMMT) filled Epoxy nanocomposite has the smallest

width of trace and consequently observed that improved resistance to wear.
