ABSTRACT:
A hybrid metal composite rotor hub retention plate having high strength and reduced weight. The retention plate comprises a metallic perimeter support structure and a plurality of metallic spokes that extend inwardly from the perimeter structure to a hub. The perimeter structure, hub and spokes define at least three holes. The perimeter structure and spokes have upper and lower surfaces. Fiber reinforced resin matrix composite capable of reacting to bending loads, in-plane shear and axial loads is bonded to the upper and lower surfaces. The hybrid metal composite rotor hub retention plate is made by forming the metal structure and using the metal structure as a mold for the fiber reinforced resin matrix composite.
