Beschreibung
Zusammenfassung:	A method for manufacturing a cylindrical part from composite material, and a molding device to implement the method, the method including: installation of a fibrous structure on a horizontal mandrel; formation of an annular enclosure for molding around the fibrous structure and the mandrel; supply of the enclosure with resin via a first axial end, while keeping a second axial end of the enclosure at a pressure lower than a supply pressure of the resin. The second end includes at least two sectors of vents in a form of ring sectors, each being independently kept at a pressure lower than the supply pressure.
