Title (EN) PRESSURE VESSEL AND METHOD FOR FORMING AN OUTER LAYER OF A PRESSURE VESSEL
(FR) RÉCIPIENT SOUS PRESSION ET PROCÉDÉ DE FORMATION D'UNE COUCHE EXTERNE D'UN RÉCIPIENT SOUS PRESSION
Abstract:
(EN) A method for forming an outer layer (2, 3) around a liner (1) having a cylindrical portion (1a), in order to obtain a pressure vessel. The method comprises: forming one or more hoop wrapping layers (2) by wrapping one or more first fibre bundles with a first fibre angle between 80 and 100 degrees with respect to the axial direction of the cylindrical portion (1a); and forming one or more braided layers (3) by braiding one or more second fibre bundles with a second fibre angle below 75 degrees with respect to the axial direction of the cylindrical portion (1a). The one or more hoop wrapping (2) and braided (3) layers together form an outer layer around the cylindrical portion (1a), wherein preferably the hoop wrapping layers (2) comprise between 5 and 30 weight percent of the total fibre content of the outer layer; and the braided layers (3) comprise between 70 and 95 weight percent thereof.
(FR) L'invention concerne un procédé de formation d'une couche externe autour d'un revêtement ayant une partie cylindrique, afin d'obtenir un récipient sous pression. Le procédé consiste à : fournir une ou plusieurs couches d'enveloppement tangentiel par enveloppement d'un ou de plusieurs premiers faisceaux de fibres avec un premier angle de fibre entre 80 et 100 degrés par rapport à la direction axiale de la partie cylindrique ; et former une ou plusieurs couches tressées par tressage d'un ou de plusieurs seconds faisceaux de fibres avec un second angle de fibre inférieur à 75 degrés par rapport à la direction axiale de la partie cylindrique. La ou les couches d'enveloppement tangentiel et tressées forment ensemble une couche externe autour de la partie cylindrique, de préférence, les couches d'enveloppement tangentiel constituant entre 5 et 30 pour cent en poids de la teneur totale en fibres de la couche externe ; et les couches tressées constituant entre 70 et 95 pour cent en poids de celle-ci.
