On the Friction and Wear of Short Glass Fiber Reinforced Nylon

The effects of load, velocity and lubricant on the tribological properties of short glass fiber reinforced nylon were investigated by ring-block wear tester. The wear mechanism was also analyzed through SEM. It is found that the friction coefficient first decreases with load; then itincreases with load; and it also increases with velocity. The wear mass loss of material increases with load and velocity continuously. The main wear mechanism is adhesive and fatigue wear. The friction coefficient greatly decreases under lubrication. With oil lubricant, the material has nearly no wear, while the wear was bigger under water lubrication than that with no lubricant.
