    摘要: PROBLEM TO BE SOLVED: To provide a composite flywheel rim and its manufacturing method which is favorable in costs and operates at high speed. SOLUTION: The composite flywheel rim provides a plurality of fiber layers within each of a plurality of adjacent zones in a radial direction. Layers in an intermediate zone provide a mixture of carbon fiber tows and glass fiber tows. A rate of the carbon fiber tows and glass fiber tows in each layer of any single zone is constant, and further, the rate incrementally increases zone-by- zone radially toward outside the rim, and the distribution of the carbon fiber tows is macroscopically uniform in each zone. The flywheel rim is made by winding a band of fiber tows impregnated by wet resin on a mandrel. The microscopically uniform distribution can be attained by adjusting interrelationship between a feeding length and winding length of fibers against rotation of the mandrel when winding the band on the mandrel.
