Patent

CA 2212244

The pressure vessel of the present invention comprises an inner shell capable of serving as a gas barrier and a pressure resistant outer shell provided to cover the inner shell, said outer shell being made of an FRP comprising reinforcing fibers and a resin and is 35 GPa or more in tensile modulus and 1.5% or more in tensile breaking strain. The present invention can provide a pressure vessel not only light in weight, but also excellent in retaining its internal pressure against repetitive impacts and also excellent in reliability. The process for producing a pressure vessel of the present invention comprises the step of forming a pressure resistant outer shell made of an FRP comprising reinforcing fibers and a resin and is 35 GPa or more in tensile modulus and 1.5% or more in tensile breaking strain, around an inner shell capable of serving as a gas barrier, by a filament winding method or a tape winding method. The present invention can produce a pressure vessel excellent in retaining its internal pressure, excellent in reliability, and light in weight at a low cost.

Le récipient de pression, selon l'invention, a une coque interne ayant des propriétés de barrière de gaz et une coque externe anti-pression réalisée de manière à couvrir la coque interne, la coque externe étant constituée de résine renforcée par des fibres de verre (FRP), ayant un module d'élasticité en traction de 35 GPa ou plus et un allongement à la rupture en traction de 1,5 % ou plus. Il est ainsi possible d'avoir un récipient de pression qui a une bonne résistance aux chocs répétés et une bonne fiabilité, pour ne pas mentionner le poids faible. Egalement, l'invention concerne un procédé de fabrication d'un récipient de pression consisttant à former une coque de pression externe qui est constituée de résine renforcée par des fibres de verre ayant un module d'élasticité en traction de 35 Gpa ou plus et un allongement à la rupture en traction de 1,5 % ou plus, autour d'une coque interne, ayant des propriétés de barrière de gaz, par un procédé d'enroulement d'un filament ou d'un ruban. Il est ainsi possible de produire un récipient de pression qui est bon marché et qui résiste bien aux pressions, en étant fiable et léger.
