Forming method of composite material rotating cylinder, composite material rotating cylinder and ship

The invention provides a forming method of a composite material rotating cylinder, the composite material rotating cylinder and a ship, the composite material rotating cylinder comprises a plurality of annular units which are coaxially arranged in an equal-diameter mode, and the annular units are prepared in an integrated forming mode. According to the forming method of the composite material rotating cylinder, circumferential integral forming of the flettner composite material rotating cylinder can be achieved, complex operation procedures such as slice pouring and mold closing are avoided, the production efficiency of products is improved, and meanwhile the appearance quality such as the roundness of the products is improved; resin in the composite material rotating cylinder is accurately and uniformly distributed, the adverse effect of gravity on resin uniform distribution in the pouring forming process is eliminated, circumferential high-precision mass uniform distribution control is achieved, and the rot
