Abstract:
1. A filament winding method for performing a hoop winding step following a helical winding step, wherein the hoop winding step includes, a first step of fixing a first end of a fiber bundle including a thermosetting resin or a thermoplastic resin to an outer circumferential surface of a liner at a starting position of hoop winding, wherein a second step of hoop winding the fiber bundle having the first end fixed to the outer circumferential surface in the first step, and after the hoop winding, gripping the fiber bundle at an upstream position in a fiber bundle supplying direction with respect to the heater, a third step of fixing a second end of the fiber bundle hoop wound in the second step to the outer circumferential surface at an ending position of the hoop winding, wherein a fourth step of cutting the fiber bundle upstream in the fiber bundle supplying direction of a position where the fiber bundle is fixed in the third step.
