Abstract: Porous polyimide composite has become the first choice of the material of aerospace bearing cages due to its good self-lubricating property. However, its poor thermal conductivity and wear resistance can lead to the shortened bearing service life and seriously affect the reliability of the control system of the aerospace vehicle. By mechanically mixing the graphene-modified porous polyimide composite, this work studied the microstructure, tribological properties and thermal conductivity of the material. The results show that the modified porous polyimide composite has excellent tribological properties and thermal conductivity. When the content of graphene is 1.0wt%, the thermal conductivity and the wear rate of material is 0.41 W/(m·K) and 43.25×10-5 mm3/(N·m), respectively, increasing by 36.9% and 27.3% over those of the unmodified composite material. As such, the modified composite cage has potential applications for prolonging the service life of aerospace bearings.
