AiResearch has successfully operated a 23-in.-diameter, Kevlar-reinforced, epoxy flywheel in a design evaluation test for the Department of Energy electric-powered passenger vehicle. This composite material flywheel was subjected to 1000 deep acceleration-deceleration cycles of 12,500 to 25,000 rpm for two weeks. These accelerated life cycles represent an expected vehicle life of 10 years. The multiring flywheel is rim-mounted on a four-spoke aluminum hub. The rim comprises a set of nested, S-2 fiberglass epoxy rings reinforced with Kevlar 29 and Kevlar 49. Candidate materials considered for this design will be compared in terms of mechanical properties and relative material costs per unit of stored energy.
