Abstract
A method for manufacturing a hollow structure suitable for example as reservoir for pressurized fluids, which structure is obtained by curving over a part of its length a corrugated tube provided circumferentially in the hollow of its waves with a hardenable fiber reinforced composition, then subjecting the tube thus curved over at least a part of its length to a treatment for hardening the hardenable composition. The tube may comprise longitudinal reinforcements (braid or layers of widely spaced helical wires), the ends of the tube being possibly equipped with systems for communicating with the outside or for sealing, the final shaping being followed by a treatment for hardening said composition. The winding of the tube may be carried out about a central core or drum.
