A flywheel is clean, environmentally friendly and efficient mean of energy storage. In this work, a systematic path for fabrication of flywheel with enhanced gravimetric energy storage (energy per unit mass) is explored. The limiting factor for flywheels is material strength since the flywheel will burst due to centrifugal stresses if spun at too high of angular velocity. Many composite flywheels are limited not by fiber failure, but matrix dominated failure.
We address the need for high specific strength material by developing novel nanocomposite materials reinforced with strong electrospun carbon nanofibers. In this study, following the stress analysis of the rotating fiber composite flywheel, we implemented strong carbon nanofibers in the region of experiencing high radial stress. Our results pointing out to the improvement in the energy density of the flywheel by 14% by addition of only 2 wt% CNFs in the region of high radial stress.
