Abstract:

A plane skateboard sample was prepared by adding treated graphene and carbon fiber to PTFE, and the steps were carried out by weighing material, ball milling, cold pressing, sintering and other procedures. The friction and wear properties of the plane skateboard specimen were studied  by MMG10 friction and wear tester of atmosphere protection. The microstructure of the friction surface of the plane skateboard was observed by scanning electron microscopy,and the lubrication mechanism of graphene and carbon fiber was discussed. The experimental results show the addition of graphene can reduce the friction coefficient of the plane skateboard specimen, and the addition of carbon fiber can obviously improve the wear resistance of the plane skateboard. The friction and wear properties of flat skate specimens containing 2% graphene and 30% carbon fiber are the best.

Key words: graphene, scanning electron microscopy, carbon fiber, friction and wear
