Producing self-lubricating fabric composites with excellent wear resistance and long service life is desired for their use in practical application, yet still challenging. Therefore, a novel nanoparticle of talc-molybdenum sulfide (MoS₂) hybrid nanosheets was synthesized via one-step hydrothermal reaction in this work and incorporated into the Nomex/polytetrafluoroethylene (PTFE) self-lubricating fabric composites. The spectroscopic and microscopic characterization demonstrated that the talc-MoS₂ nanosheets were successfully synthesized. The talc-MoS₂ nanosheets exhibit the obvious layered structure and covered with MoS₂. The effect of talc-MoS₂ hybrid nanosheets on the tribological performance of fabric composites was systematically evaluated by tri-pin on disk tribometer. The results show that the talc-MoS₂ nanosheets increased the thermal stability, thermal conductivity, tensile strength, and hardness of composite and was favorable for forming high-quality transfer film on the surface of counterpart pin during the wear process owing to the cooperation effect of talc-MoS₂. The wear rate of talc-MoS₂-reinforced composite was reduced by 30%–53% under different conditions compared with pure fabric composite.
