Abstract: The composite sleeve made by tension winding is an effective way to prevent the damage of permanent magnet of rotor for high-speed permanent magnet motor. In this paper, the strength of NOL ring made by different winding tensions and the curing residual stress of winding composite structure were experimentally studied, in order to study on the influence of winding tension on the strength of composite material. The effects of winding tension on the material strength of composites and the residual stress of winding structure were found. The theoretical estimation method of tensile strength for filament winding materials considering the influence of winding tension and the variation law of fiber volume fraction was established. The mechanism of the influence of winding tension on the strength of composite material was found. A reference for choosing appropriate winding tension for winding composite structures was provided.

Key words: filament wound composites, winding tension, residual stress, strength
