Abrasive Wear Performance of CNT/PP Composites

Abstract:

In this work, abrasive wear performance of multi-walled carbon nanotube (CNT) reinforced polypropylene (PP) has been studied. Various weight percentage of CNT/PP nanocomposites were prepared through melt intercalation with the aid of twin screw extruder. Prepared composites were subjected to sliding wear against silicon carbide abrasive paper with the aid of pin-on-disc configuration. Worn out surface morphology were observed under microscope and non-contact profilometer to understand the wear mechanism. Since the dominant friction mechanism observed to be is ploughing, no lubrication effect of CNT was observed. CNT/PP composite exhibits inferior wear resistance than unfilled PP due to its brittleness. With increased CNT, wear resistance found to decreases.
