Abstract
An advanced composite flywheel hub and associated method are described for use in a flywheel rotor assembly that includes a shaft and a rim. The hub includes a shaft engaging portion and a rim engaging portion, and is configured for maintaining engagement with the shaft and the rim during operational rotation of the flywheel rotor assembly. The hub exhibits a bending mode, and includes a first layer having axial fibers for stiffening the hub with respect to the bending mode. The hub can further include a stiffening arrangement for increasing the radial stiffness of the shaft engaging portion.
