A method of manufacturing a tank of cylindrical overall shape of round cross section for the storage of high-pressure fluid, the tank comprising, about an axis, a liner and a structural layer, the method comprising steps successively involving:
- placing metal end pieces inside a tube intended to form the liner;
- shaping the ends of the tube to the exterior shape of the end pieces by locally reducing the diameter of the tube to form a preform;
- and
- winding at least one tape of fibre impregnated with thermosetting resin around the liner to form the structural layer of the tank.
