Abstract

The energy storage flywheel device (6) includes a plurality of annular shaped composite sections (8) and an annular shaped insert (10). The insert (10) has a specific radial strength substantially greater than the composite sections' specific radial strength. The composite sections (8) and the insert (10) are alternately stacked such that they have a common axis of rotation. They are bonded to each other such that shear stress is transferred between the composite sections (8) and insert (10). In some applications, the flywheel (6) may comprise at least one annular shaped metal matrix composite section (8).
