Investigation of tribological properties of polyimide/carbon nanotube nanocomposites

Polyimide/carbon nanotube (PI/CNT) nanocomposites with different proportions of CNT were fabricated by in situ process. The bending strength and microhardness of the PI/CNT nanocomposites were measured. The friction and wear behavior of the nanocomposites was evaluated on an M-2000 friction and wear tester. As the results, the bending strength and microhardness of the PI/CNT nanocomposites increased with increasing CNT content and reached stable...
