Abstract:

Several effects that can limit the performance of bi-directionally reinforced composite flywheels are investigated. These effects include potential shear failures, degraded properties and variations caused by manufacturing. Finite element analyses are used to determine both the in-plane and interlaminar shear stresses that arise from the discreteness of the individual radial reinforcements. The degradation of material properties due to high biaxial stress levels, especially a drop in shear modulus, is also investigated. Degraded properties are obtained experimentally and used in the evaluation of flywheel performance. Also included is an analysis to determine the feasibility of a static simulation test. In addition, the effect of asymmetric material property variation on flywheel imbalance was investigated.
