Abstract: | POM/graphite/Ekonol composites were prepared by the Torque Rheometer mixing and compression molding, and their hardness, compressive
and impact strengths have been tested. The tribology behaviour was also investigated by the friction and wear experiment.
The worn surface of the composite was studied by SEM technique, and on its basis, the wear mechanism was analysed. Results
show that it was possible to prepare POM/graphite/Ekonol composites of high tribology performance and good mechanical properties
by the Torque Rheometer mixing and compression molding. With the rise of Ekonol content, the wear mechanism was changed from
adhesion plus plough to fatigue wear plus abrasive wear. |
