Abstract
A hydrodynamic thrust bearing pad includes a composite laminate including at least one ply including a plurality of fibers oriented in at least one direction, and a bearing surface configured to confront a rotating thrust surface of a rotating shaft for transmitting axial thrust loads from the rotating shaft to the composite laminate. The bearing pad also includes a support surface configured to confront a stationary surface of a stationary housing for transmitting the axial thrust loads from the composite laminate to the stationary housing, and at least one side surface extending between the bearing and support surfaces. The at least one ply is configured to expand non-uniformly when heated from a first temperature to a second temperature for causing the composite laminate to warp from an unstressed state to a stressed state.
