The use of composite-material flywheels for large-scale storage of electricity is assessed. To achieve useful storage of about 10 MWh, large composite-material components need to be constructed and supported, and ancillary equipment developed to extract power from the flywheels. In particular, the costs of this method of storage are considered in order to evaluate the economic aspect of composite flywheels. A curve for useful energy stored vs flywheel mass is presented for different materials - Kevlar/epoxy, carbon/epoxy, glass/epoxy (all with about 60 vol% fiber) and steel. Another curve for tension/tension fatigue properties of unidirectional composites, with about 60 vol% fiber is given. Both a radially thin hoop wound rim and rods of aligned fibers mounted in a sweep's brush configuration for composite flywheel construction are discussed.
