Study on Tribological Behaviors of Glass Fiber Reinforced Nylon 1010 Based Composites

The glass fiber reinforced nylon 1010 based composites were prepared by micro rejector. The tribological behaviors of composites were investigated through a ring block wear tester. The results show that the tribological properties of the composite materials are significantly affected by the proportion of glass fiber, and the best reinforcing effect of the composite can be attained in the proportion of glass fiber of 35wt.%. The friction coefficient and wear mass loss are continuously increased with the sliding velocity increment. The main wear mechanisms of nylon 1010 composites are fatigue fracture and adhesive wear and it can be observed that the GF is rubbed, fractured and peeled off under dry friction condition. Composites are slightly transferred to counterface surface under oil lubrication conditions, so the friction coefficient and wear mass loss decrease sharply compared to dry friction condition. Meanwhile, chemical corrosion wear and abrasive wear of nylon 1010 composites play a main role in water lubrication conditions, and the friction coefficient of composites is greatly lower than that in dry friction conditions, while wear rate increases.
