The Mechanical and Tribological Properties of a Polyurethane Composite Filled with CNT

Abstract:

Effect of carbon nanotube(CNT) on structure, strength and tribological behavior of CNT/PU composites is studied in the filler range of 5 vol%. It is found that differences in filler content used to determine the type of structure evolved and patterns of variation of mechanical properties, friction and wear in response to increasing filler content. It is found that wear of low-filled CNT/PU composites is dominated by delamination mechanism and wear resistance changes correlate with structural transformations of the composites. The maximum increase in wear resistance of the PU composites is reached at 2 vol% filling.
