1. A seal plate for a rotary machine, the seal plate comprising:
a hub with a bore configured to be centered on a central axis of the rotary machine; and
a disk portion extending radially outwards from the hub, the hub and the disk portion together comprising:
a plastic substrate, the plastic substrate comprising:
a matrix material; and
fibers embedded in the matrix material, the fibers having a first coefficient of thermal expansion; and
a metal plating disposed on at least a portion of an outer surface of the plastic substrate, the metal plating having a second coefficient of thermal expansion of the metal plating;
wherein a bulk coefficient of thermal expansion of the plastic substrate at the outer surface of the plastic substrate substantially matches the second coefficient of thermal expansion of the metal plating.
