Cu/Ti3C2Tx composites with Ti3C2Tx content of 5 vol%, 10 vol% and 20 vol% were prepared by using a molecular-level mixing process and spark plasma sintering(SPS). Influence of Ti3C2Tx content on electrical, mechanical and tribological properties was investigated. The result showed that relative density and electrical conductivity of Cu/Ti3C2Tx composites gradually decreased with the Ti3C2Tx content increase, while the tensile strength of Cu/Ti3C2Txcomposites increased at first and then decreased. When the Ti3C2Tx content was 5 vol%, the tensile strength of Cu/Ti3C2Tx composites increased by 43% than that of pure copper. Tribological properties of Cu/Ti3C2Tx composites were enhanced by the addition of Ti3C2Tx. When the Ti3C2Tx content was 10 vol%, the wear rate of Cu/Ti3C2Tx composites was 2.55×10–7 mm3/(N·m), which was one magnitude lower than that of pure copper.
