ABSTRACT:
Vessel for storing a fluid under pressure, such as a gas storage vessel, of the type comprising an internal casing surrounded by an external hooping. The internal casing has symmetry about a longitudinal axis, a central pipe section and two extremity portions, and at least one of the extremity portions protruding outwardly. The hooping is of reinforcing fibers coated with a thermoplastic of thermosetting binder, and opposite the pipe section the hooping has at least one layer of fibers, known as longitudinal fibers, having a flat winding pattern and a winding angle as small as possible, so as to allow a boss, centered on the longitudinal axis of the protruded extremity, to be uncovered with fibers. Further, the hooping has at least one layer of fibers, known as circumferential fibers, having an almost 90.degree. winding angle. Moreover, the pipe section further comprises at least one layer of fibers having a winding pattern that is either flat or helical with a winding angle (.alpha..sub.n) of between the angle (.alpha.) of the longitudinal fibers and 90.degree..
