Title
(EN) INTERNAL ENCLOSURE FOR PRESSURIZED FLUID STORAGE TANK FOR A MOTOR VEHICLE
(FR) ENVELOPPE INTERNE POUR RESERVOIR DE STOCKAGE DE FLUIDE SOUS PRESSION POUR VEHICULE AUTOMOBILE
Abstract
(EN)
The invention relates to an internal enclosure (3) for a pressurized fluid storage tank (1) for a motor vehicle, characterized in that it comprises: - a hollow body (7) comprising at least one layer made of a first polymer material, - a collar (9) arranged on the hollow body (7) defining an opening (17) of the hollow body (7), the collar (9) being configured to receive an interface part (5, 10) mounted on the collar (9) in a sealed manner due to a sealing gasket (19) arranged between the collar (9) and the interface part (5, 10), the collar (9) being made of a composite material composed of a second polymer material filled with reinforcing fibers, the composite material having a resistance to deformation that is greater than the resistance to deformation of the first polymer material, and the collar (9) being joined to the hollow body (7) by molecular entanglement of the polymer chains of the first polymer material and the polymer chains of the second polymer material. The invention further relates to methods for manufacturing such an internal enclosure (3), as well as a storage tank (1) comprising such an internal enclosure (3).
(FR)
L'invention concerne une enveloppe interne (3) pour réservoir (1) de stockage de fluide sous pression pour véhicule automobile, caractérisée en ce qu'elle comporte : - un corps creux (7) comportant au moins une couche réalisée dans un premier matériau polymère, - un col (9) disposé sur le corps creux (7) et délimitant une ouverture (17) du corps creux (7), le col (9) étant configuré pour recevoir une pièce d'interface (5, 10) rapportée sur le col (9) de façon étanche grâce à un joint d'étanchéité (19) disposé entre le col (9) et la pièce d'interface (5, 10), le col (9) étant réalisé dans un matériau composite composé d'un deuxième matériau polymère chargé de fibres de renfort, le matériau composite présentant une résistance à la déformation supérieure à la résistance à la déformation du premier matériau polymère, et le col (9) étant relié au corps creux (7) par enchevêtrement moléculaire de chaînes polymériques du premier matériau polymère et de chaînes polymériques du deuxième matériau polymère. L'invention concerne en outre des procédés de fabrication d'une telle enveloppe interne (3), ainsi qu'un réservoir (1) de stockage comprenant une telle enveloppe interne (3).
