Technical Report ·
OSTI ID:6275855
A flywheel rotor has been designed and fabricated to demonstrate energy densities ranging from 50.6 watt-hour/kg (23 watt-hour/lb) to 88 watt-hour/kg (40 watt-hour/lb). The design is composed of a multiring rim made of S-2 glass/epoxy and Kevlar/epoxy composite materials, mounted on a four-spoke aluminum and graphite/epoxy composite hub. Ten flywheel rotors were produced for test.
