; ;
Progress during the third reporting period (July 1, 1979 to January 10, 1980) of the Lawrence Livermore Laboratory Subcontract No. 2749309 for the development of a laminated, composite, flywheel disc for use in hybrid flywheel/electric-powered vehicles is discussed. The General Electric Company has developed and begun to optimize a concept based upon a laminated disc and a filament-wound outer ring assembled with an interference fit between these two components. The laminated, central disc is made of S2-glass-epoxy and the outer ring is filament-wound graphite-epoxy. Projections for this particular flywheel design indicate that it will be both practical and relatively inexpensive to produce, and that it will have a high energy-density capacity. Two hybrid composite flywheels of 37 cm O.D. were successfully assembled. This report summarizes the spin-test data actually gathered, discusses the nondestructive test data, and describes the fabrication techniques developed for the hybrid flywheel assembly. (LCL)
