  "textContent": "A rotor for use in a turbomachine includes a hub (100) centered on a central axis and having a disk portion (220) and a shaft portion (218) and a blade (202) extending outward from the hub. The hub and the blade together include a plastic substrate (12, 32) and metal plating (24) disposed on at least apportion of an outer surface of the plastic substrate. The plastic substrate has a matrix material (14, 34) and fibers (16, 36) embedded in the matrix material. The fibers have a first coefficient of thermal expansion. The metal plating has a second coefficient of thermal expansion. The fibers are selected such that 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.",
