Role of Nano Clay in Improving Wear Properties of Polypropylene in Dry Sliding Condition

Abstract

The friction and wear behaviour of polymer blends and composites are complex when compared to the ordinary materials because the individual components have their unique response towards the friction and wear. Polypropylene-nanoclay composites were prepared using the melt blend method. The sliding wear of polypropylene and nano clay (montmorillonite) blends are evaluated as a function of applied load and composition against a steel counter face in dry condition. Wear performance is investigated and presented in detail. Microstructure and worn surfaces of samples were observed by scanning electron microscope. The wear phenomenon has been discussed on the basis of weight loss and worn surfaces.
