Abstract
A method for manufacturing a cylindrical structure having an axial direction includes: winding a first layer around a mandrel; winding a second layer around the mandrel; winding a third layer around the mandrel; and joining the layers together by using a resin. Each layer includes a plurality of fabrics each made of fibers. The fabrics of each layer form a join line extending in a circumferential direction with edges of the fabrics in contact with each other. The join lines of the first, second and third layers are displaced in the axial direction from one another.
