Tribological Properties of PA6 Composites Modified with PTFE and UHMWPE

PA6 composites modified with PTFE and UHMWPE were prepared by molten blending method. Tribological properties were investigated in terms of coefficient of friction and the friction stability. Moreover, the wear mechanisms were discussed on the basis of micrographs of the worn surface of PA6 composites. The results show that PTFE-modified PA6 composite had better tribological properties of PA6 than UHMWPE-modified PA6 composite. PA6 composite with PTFE and UHMWPE had more excellent tribology performance comparing to PA6-PTFE and PA6-UHMWPE composites. The wear mechanism varied as the addition amount of PTFE and UHMWPE.
