STUDY ON FRICTION AND WEAR PROPERTY OF MODIFIED PI

The effect of PTFE with different content on the property of composite material PI/PTFE is discussed in this paper. The results show that the addition of PTFE can improve the friction and wear property of PI effectively; when the content of PTFE is about 10～20%, the friction coefficient of PI decreases apparently. Co wear property mainly includes abrasive wear and adhesive wear. The results show that when the content of PTFE is 20%, the comprehensive property of composite material is the best.
