Abstract
A method for hooping and maintaining in compression a core by a sheath, with the sheath being made of a composite material and having an internal cross section which is less than an external cross section of the core. The core and the sheath are aligned by centering them with respect to each other, and a prior tensile force is exerted over the core to provide a suitable sealing between the portion in contact of each of the ends of the core and of the sheath. A pressurized fluid is injected into the sheath in a direction of the core, to increase the cross section of the sheath by expanding the sheath in a circumferential direction. The core is thereby gradually inserted into the sheath. When the insertion is complete, fluid injection is ceased and an expendable portion of the sheath is cut off.
