The LLL flywheel program includes the determination of engineering properties of the composite materials which are considered most likely to be used in flywheel designs. Mechanical as well as thermal properties are determined. The effect of the volume percent fiber on these properties has been examined. A comparison of the properties of filament-wound composites of three fibers--Kevlar 49, S2-glass, and E-glass--in the same epoxy matrix indicates that the results of engineering property tests can predict the strengths obtained in rotor spin and burst tests, if transverse as well as longitudinal properties are considered. Differences in the relative properties of the three composites enable the flywheel designer to tailor the fiber composite properties, by careful choice of materials, to the design requirements.
