Iron tailings is the bulk waste produced by steel plants that has not yet been used. In this study, the mineral composition of iron tailings was determined by XRD. The microstructure was observed by SEM-BEI. Resin-based composite materials with different contents of iron tailings were prepared by compression molding method and the tribological properties of the composites were studied. The results showed that: when the contents of iron tailings were 10%, 20%, 30%, 40% and 50%, the friction and wear properties of the resin-based composite materials can meet the standards for automotive clutch (GB/T 5764-1998). Among these samples, the sample with 20% iron tailings had the best performance. This paper provides a new way for the use of iron tailings.
