Evaluation on Erosion Wear Behaviour of Epoxy/o-MMT Nanocomposites

In the present investigation, authors made an attempt to study the erosion solid behaviour of pristine epoxy and their nanocomposites. The nanocomposites have been prepared with varying amounts viz., 0, 1, 3 and 5 wt% of organo nanoclay (o-MMT) were prepared by in situ polymerisation at room temperature. The nanocomposites were subjected to flexural tests, and the flexural properties were found to be highest in the case of 5% o-MMT filled naocomposites. The solid particle erosion behaviour of epoxy and their nanocomposites has been investigated. The erosion rates of these composites were evaluated at various impingement angles (30°, 45°, 60°, 90°) with a particle velocity of 70 m/s. Also morphological study was carried out for wear out surfaces of all the nanocomposites using scanning electron microscopy (SEM).
