Abstract:
Mechanical and tribological properties of polyimide-based three-species antifriction composites filled with polytetrafluoroethylene and milled carbon fibers with a mass fraction of 5–15% are studied. It is shown that the elasticity modulus can be almost doubled by adding milled carbon fibers. The study of tribological characteristics shows that the wear of surfaces can be reduced by using the above-mentioned complex filler by a factor of 265 in the case of metal-polymer tribocoupling and by a factor of 255 in the case of ceramic-polymer tribocoupling. Optimal compositions of the polyimide-based three-species solid lubricant composite to be used in the cases of metal-polymer and ceramic-polymer tribocoupling are determined by using an in-house computer algorithm.
Keywords:
