Summary
A program for development of fiber composite flywheels and associated containment was started in May 1976 at the Oak Ridge Y-12 Plant. The development of the first test flywheel in the program is described. The flywheel design uses a thick rim element and unidirectional fiber composite bands which pass around the rim diameter and across a metal hub fitted to the drive shaft. The individual bands are meshed together at the hub and function similar to spokes on a wheel. The design is called the ''Bandwrap'' flywheel. The development leading to the first test flywheel is reported in the May to September 1976 Project Report. In the development process, conceptual designs were selected for detailed study. After detailed study, the Bandwrap design was selected for fabrication and test. After fabrication, the flywheel was spun to 18,000 rpm where a predicted delamination occurred in the rim. At this speed, the energy stored was 0.25 kwh and the energy density was 10.1 Wh/lb.
