Abstract
The present disclosure relates to bearing and seal assemblies comprising a composite structure which includes a substrate and a layer disposed on the substrate. The layer disposed on the substrate includes a polyimide matrix and a filler dispersed within the polyimide matrix. The filler can be a thermoplastic polymer, such as PTFE, and/or an organic filler. The bearing assembly can exhibit a synergistic improvement in wear resistance and coefficient of friction.
