Hannibal, A J

The manufacturing methodology for the composite ring of a disk/ring flywheel configuration is described. The disk may be a laminated composite construction as fabricated by General Electric or a Sheet Molding Compoung (SMC) construction as fabricated by Owens Corning. The ring is a wet filament winding of graphite fiber and epoxy. The objectives of this program were to: produce filament wound composite rings; fabricate filament wound flat panels in order to evaluate the material properties of the composite; incorporate SiC whiskers into both the composite rings and panels in an attempt to enhance the transverse strength of the composite; investigate the effects of winding tension on the residual stresses caused by manufacturing processes; fabricate aluminum hubs and bond them via elastomeric interlayers to Owens-Corning supplied SMC disks; and assemble several composite rings and SMC disks. Several flywheel assemblies, including the bonded hubs, were later tested to failure in a flywheel test facility. The remaining unassembled rings and panels were sent to LLNL to undergo a series of destructive and nondestructive tests.
