Abstract: In view of ZrO₂ fiber which has the excellent mechanical properties and high temperature performance has not been developed to ZrO₂ fiber composites as anti-wear materials. This paper prepared ZrO₂ fiber reinforced epoxy resin composites and carried out a research on their tribological properties.Results indicated that the ZrO₂ fiber can improve the wear rate of the composite material with respect to the ZrO₂ powder. When the content of the ZrO₂ fiber is 30wt%, the tribological performance of the ZrO₂ fiberepoxy resin composite is the best, and the wear rate can reach 10^－5 mm³/(N·m) order of magnitude. The conclusion can guide the preparation and performance improvement of other fiber self-lubricating materials, so as to develop the ZrO₂ fiber composites with excellent mechanical properties and tribological properties.
