Abstract:
A flywheel formed of a composite material having fibers, oriented substantially in a circumferential direction around the flywheel, embedded in a matrix material. The flywheel having an inner surface, an outer surface, and a thickness therebetween and defining an axis of rotation. A plurality of load masses are distributed circumferentially on the inner surface at a longitudinal segment along the axis. A rotation of the flywheel about the axis with a rotational velocity generating hoop stress in the fibers in the circumferential direction and through-thickness stress is generated in the matrix material in a radial direction. Each load mass produces a force on the inner surface operative to reduce the maximum through-thickness stress in the matrix material as the flywheel rotates about the axis. The rotational velocity otherwise sufficient to produce structural failure of the matrix material produces structural failure of the fibers and not the matrix material.

Claim (Index 10):
The apparatus of  claim 1  wherein the plurality of load masses is a first plurality of load masses, the longitudinal segment is a first longitudinal segment, and the flywheel has an axial length, and further comprising a plurality of additional pluralities of load masses, each additional plurality of load masses distributed circumferentially around, and coupled to, the inner surface of the flywheel at a respective additional longitudinal segment along the axis of rotation, the first longitudinal segment and the plurality of additional longitudinal segments distributed substantially uniformly along the axial length of the flywheel, rotation of the flywheel causing each load mass in each additional plurality of load masses to produce a radially outwardly directed force on the inner surface of the flywheel, the force acting to reduce the maximum through-thickness stress in the matrix such that the matrix material does not fail in the radial direction at any of the additional longitudinal segments at the second rotational velocity.
