Abstract

This paper discusses a method for real-time life prediction of composite flywheel rotor considering material degradation. Viscoelastic material properties of Glass/Ep Graphite/Ep and Hybrid/Ep (i.e. Glass+Graphite/Ep) were first calculated using data obtained from Dynamic Mechanical Analysis test (DMA). Based on the micromechanics of failure (MMF), real-time life prediction for a high performance 10kWh six-rim composite flywheel rotor with 50-years initial life was developed, and a real-time residual life prediction method using health monitoring system was suggested.
