Development of filament reinforced polymer (FRP) flywheels for energy storage in vehicles has been continuing at ABL with emphasis on material selection and design synthesis based on the filament winding process. Three species of designs have been studied: Helically wound shells; circumferentially wound rims with radial spokes and circumferentially wound contoured disks. The obejective has been to evaluate the potential of design concepts with commercial merit. A new approach to the type 3 flywheel offers competitive performance in a wheel configuration that is more compact than other types is also attractive from a mass production viewpoint. Combining optimum contour with programmed winding tension in a process that fixes the winding tension as the wheel is fabricated results in rated performance approaching 30 W-hr/lb and 1 W-hr/cu in. for a rotor storing 1270 W-hr at the design operating speed. Design and fabrication are in progress under contract from DOE/Sandia. A description of the design concept, the basic theory of the design, and a summary of material properties are provided. (Peters)
