Ekonol/G/MoS2/POM composite was prepared by blendingcompressing method with torque rheometer. The tribological behavior has been studied by the ring-block wear tester. The wear surface of the composite has been investigated by the SEM technique, and on the base of it, wear mechanism has been analyzed. Results shown that compared with pure POM, the composite has better tfibological properties; With the increase of Ekonol content, the wear mechanism of the composite has been chan...
