Title: Flywheel rotor and containment technology development for FY 1982

Conference ·
OSTI ID:6792691

The status of technology development for an efficient, economical, and practical composite flywheel having an energy density of 88 Wh/kg (20 to 25 E Wh/lb) and an energy storge capacity of approximately 1 kWh is reported. Progress is also reported in the development of a fail-safe, lightweight, and low cost composite containment for the flywheel. One containment design was selected for prototype fabrication and testing. Flywheel rotor cyclic test capability was also demonstrated and evaluated. High strength Kevlar and graphite fibers are being studied. Tests of the elastomeric bond between the rotor and hub indicate that the bond strength exceeds the minimum torque requirements for automobile applications.
