Abstract

Abstract: Several typical carbon fiber reinforced composite rings were manufactured and their stretching performance were tested. The tension strength and the typical failure mode were obtained. The composite materials can be applied to flywheel, which can reinforce mechanical behavior of energy storage flywheel and increase kinetic energy storage efficiency perunitmass. The mechanical model of composite energy storage flywheel is built based on the orthotropic elastic solid basic theory and the finite element theory. The distribution of radial and circumferential stresses as well as the radial displacement were analyzed, and the curve of the distribution has been drawn out. Also, the tension strength and the failure mode were obtained, which agreed well with the experimental results. Moreover, the distruibution of radial and circular stress, and radial displacement were caculated by the analytical model. The developed method provides a good reference for optimum and design of flywheel structure.

Key words: flywheel energy storage system; carbon fiber reinforced composite; ring; tension properties; stress distribution
