Abstract
A composite material has polyester ether ketone matrix and additionally contains 10-50 wt. % glass fibers, and one or both of 0.1-2.0 wt. % graphene and 0.1-2.0 wt. % carbon nanotubes. An electrically insulated bearing ring has an electrically insulation layer composed of the composite material disposed on at least one surface to block leakage currents, thereby inhibiting the galvanic corrosion damage of the bearing.
