Abstract
The hoop winding method allows to manufacture a reinforced tube by carrying out the following operations: The fact that the two enclosures Zand Zare distinct and independent allows pressures Pand Pto be applied independently of one another. Thus, the method allows independent radial and axial prestresses to be applied so as to optimize the strength of the hoop-wound tube.
