Zorzi and Lustenader have illustrated the attractiveness of a hybrid flywheel design concept made up of a solid, laminated central disc with a filament wound outer ring. Such a design would take advantage of the solid rotor's capability for high energy storage per swept out volume as well as its desirable dynamic characteristics while improving the energy density of the flywheel through use of high strength-to-density composite materials. Zorzi and Lustenader's work also illustrates the existence of an optimum inside-to-outside radius ratio for the exterior ring which provides maximum energy density. In preparation for fabricating flywheels to test this design concept, the present work focuses on selection of material, choice of interference fit between the disc and ring, as well as the impact of typical variations in material strength and stiffness upon the flywheels' energy density.
