  • Composite bearings having a polyimide matrix
    Patent number: 10266722
    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.
    Type: Grant
    Filed: December 21, 2017
    Date of Patent: April 23, 2019
    Assignee: SAINT-GOBAIN PERFORMANCE PLASTICS CORPORATION
    Inventors: Nafih Mekhilef, Boguslawa Czarnecka, Jeffrey H. Peet, Emeric Malefant, Blair K. Brettmann, Hongxiang Teng
