The final report on the technical effort to test an RPE-10 composite flywheel. The RPE-10 composite flywheel was designed and fabricated for vehicle use under a Sandia Laboratories contract. The flywheel (Unit No. 2) was tested to a speed of 21,600 rpm, at which time the overwrap separated from the flywheel, terminating the test. The primary cause of failure was attributed to overheating in the test cell, causing a deteriorization in material properties of the epoxy bond. The RPE-10 composite flywheel Unit No. 1 was successfully tested without failure to 24,120 rpm at Oak Ridge's Y-12 Laboratory. At this speed, the rotor stored oer 2.0 kilowatt hours of kinetic energy. (ERA citation 07:004335)
