Abstract

Flywheels are devices that can store energy in the form of kinetic energy whilst allowing for high charge and discharge rates and providing a high efficiency. This makes them extremely suitable for applications in hybrid vehicles within the automotive industry. Yet before application in this industry can take place, the potential for failure and the associated failure mechanics of composite flywheels must be sufficiently well understood to control the risk to passengers. This paper outlines a study that aims to induce failure in CFRP flywheels such that the consequences of failure can be assessed and the implications for flywheel containment can be better understood. Following a review of flywheel failures and a consideration of the stresses in one particular composite flywheel rim, a number of defect scenarios are presented and a test programme is presented based upon these considerations.
