Friction and wear of self-reinforced polymers
Tribological properties of the oriented crystallized, self-reinforced polymer materials and self-reinforcing LCPs were investigated on a pin-on-disk test system, a test system for friction property on ice and a journal bearing test system. The influence of mechanical properties, the direction of orientation, tribological conditions and the temperature on the tribological properties was studied. The mechanisms of wear were analyzed with a SEM.
The effects of self-reinforcement, lubricating and wear resistent fillers on the tribological properties are compared. The tribological properties of polymer materials can be improved by means of self-reinforcement. The effects of self-reinforcement can be revealed especially at elevated temperature and on rough surface of counterpart. In case those special tribological properties are desired, both methods can complement each other.
The investigation shows that the velocity and the pressure influence the tribological properties in a complicated way because of the viscoelastic behavior of polymers. Therefore, instead of pressure-velocity-multiplier (p*v), the influence of velocity and pressure should be evaluated separately in calculation of wear.Lesen Sie die deutsche Zusammenfassung auf Kunststoffe.de
