Carbon/carbon–copper(C/C–Cu) composites are fabricated by infiltration of Cu into Mo 2 C interlayer‐modified carbon/carbon(C/C) preforms. Effect of graphitization on the microstructure and properties of the C/C–Cu composites is studied. The C/C–Cu composite with graphitization shows lower electrical resistivity, thermal expansion coefficient, friction coefficient, and an obvious higher thermal conductivity due to higher graphitization degree. However, it presents lower flexural strength, impact toughness, and higher wear rate. The composite with graphitization exhibits mainly abrasive wear while that without graphitization exhibits mainly adhesion wear, and both composites show oxidation wear.
