Description

Druckbehälter zur Speicherung von flüssigen und/oder gasförmigen Medien unter DruckPressure vessels for storing liquid and/or gaseous media under pressure

Die vorliegende Erfindung beschreibt einen Druckbehälter zur Speicherung flüssiger und/oder gasförmiger Medien unter einem Betriebsdruck oberhalb des Atmosphärendrucks, wobei der Druckbehälter einen zur Speicherung des Mediums vorgesehenen Hohlraum umschließt und mindestens einen Anschluß zum Befüllen und /oder Entleeren aufweist. 10The present invention describes a pressure vessel for storing liquid and/or gaseous media under an operating pressure above atmospheric pressure, wherein the pressure vessel encloses a cavity provided for storing the medium and has at least one connection for filling and/or emptying. 10

Flüssige und/oder gasförmiger Medien werden üblicherweise in Druckbehältern transportiert, die den mechanischen Beanspruchungen durch Innenbzw. Außendruck sowie den weiteren Beanspruchungen mechanischer, physikalischer und chemischer Art während des Betriebes standhalten.Liquid and/or gaseous media are usually transported in pressure vessels that can withstand the mechanical stresses caused by internal and external pressure as well as other mechanical, physical and chemical stresses during operation.

Durch geeignete Kombination von Polymeren als Matrix mit hochfesten Fasern als Verstärkung und durch die Wahl eines geeigneten Verstärkungsaufbaus lassen sich, den Anforderungen entsprechend, auf das Bauteil maßgeschneiderte Werkstoffeigenschaften einstellen. Druckbehälter aus Faserkunststoffverbunden hergestellt, sind gegenüber herkömmlichen Stahl- oder Aluminiumbehältern hinsichtlich drucktechnischer Eignung gleichwertig, bieten darüber hinaus jedoch entscheidende Vorteile wie geringes Gewicht, erhöhte Korrosionsbeständigkeit und extreme Ermüdungsfestigkeit. By combining polymers as a matrix with high-strength fibers as reinforcement and by choosing a suitable reinforcement structure, material properties can be tailored to the component's requirements. Pressure vessels made from fiber-reinforced plastic composites are equivalent to conventional steel or aluminum vessels in terms of pressure-related suitability, but also offer decisive advantages such as low weight, increased corrosion resistance and extreme fatigue strength.

Aus Faserkunststoffverbunden mit polymeren Matrixsystemen hergestellte Druckbehälter sind bekannt und es existiert eine Vielzahl an Patenten.Pressure vessels made from fiber-plastic composites with polymer matrix systems are well known and a large number of patents exist.

Als Beispiel sei das Europa Patent EP0810081 A1 "Pressure Vessel and Method of Manufacturing Same" genannt. Hierbei wird beschrieben wie eine geschlossene Hüllschicht, die aus einem Kunststoff besteht, im Faserwickelverfahren mit einem Faserkunststoffverbund umhüllt wird. Ein ähnliches Behälterprinzip wird im Europapatent EP0333013 A1 "Pressure Vessels" beschrieben. Auch in diesem Falle wird eine Hüllschicht mit Fasern derart umgeben, daß die Verstärkungshülse den mechanischen Beanspruchungen standhält.One example is the European patent EP0810081 A1 "Pressure Vessel and Method of Manufacturing Same". This describes how a closed covering layer made of plastic is wrapped in a fiber-plastic composite using a fiber winding process. A similar container principle is described in the European patent EP0333013 A1 "Pressure Vessels". In this case too, a covering layer is surrounded by fibers in such a way that the reinforcing sleeve can withstand the mechanical stresses.

Die in o. a. Patenten beschriebenen Techniken weisen im Einsatz einige Unzulänglichkeiten auf, insbesondere ungeeignete Konstruktion gegen Diffusion oder Permeation des gespeicherten Mediums.The techniques described in the above patents have some shortcomings in use, in particular unsuitable construction against diffusion or permeation of the stored medium.

Als Behältergrundkörper wird derzeit häufig ein thermoplastisches Material eingesetzt. Da die nachträglich aufgebrachte Faserverstärkung nur unerheblich zur Erhöhung der Diffusions- oder Permeationsdichtigkeit beiträgt, werden die thermoplastischen Materialien entsprechend modifiziert bzw. kombiniert. Diese Maßnahmen sind sehr kostenintensiv und führen nicht zu den gewünschten Effekten geringer Diffusions- oder Permeationsraten.A thermoplastic material is currently often used as the base body of the container. Since the subsequently applied fiber reinforcement only contributes insignificantly to increasing the diffusion or permeation tightness, the thermoplastic materials are modified or combined accordingly. These measures are very costly and do not lead to the desired effects of low diffusion or permeation rates.

Die hier beschriebene Erfindung betrifft einen Druckbehälter aus Faserkunststoffverbund zur Speicherung von flüssigen und/oder gasförmigen Medien unter Druck mit einem Kunststoff - Kernbehälter wobei der Erfindung die Aufgabe zugrunde liegt, einen Druckbehälter derart weiterzubilden, daß die im Stand der Technik genannten Nachteile bzw. beschriebenen hohen Diffusions- und/oder Permeationsraten im Betrieb vermieden werden. Es soll ein Faserkunststoffverbundbehälter mit geringem Eigengewicht, hoher Korrosionsbeständigkeit und hoher Ermüdungsfestigkeit bei gleichzeitig langzeitiger Dichtheit geschaffen werden, der den mechanischen Beanspruchungen standhält und kostengünstig herzustellen ist.The invention described here relates to a pressure vessel made of fiber-plastic composite for storing liquid and/or gaseous media under pressure with a plastic core container, the invention being based on the object of developing a pressure vessel in such a way that the disadvantages mentioned in the prior art or the high diffusion and/or permeation rates described in operation are avoided. The aim is to create a fiber-plastic composite container with a low dead weight, high corrosion resistance and high fatigue strength while at the same time being leak-proof for a long time, which can withstand mechanical stress and can be produced inexpensively.

Die Erfindung ist gegenüber dem Stand der Technik von Druckbehältern aus Faserkunststoffverbund derart weitergebildet, daß insbesondere eine hohe und langzeitige geringe Diffusions- und/oder Permeationsrate sichergestellt wird.The invention is further developed compared to the prior art of pressure vessels made of fiber-plastic composites in such a way that in particular a high and long-term low diffusion and/or permeation rate is ensured.

Die Aufgabe wird gemäß einem Aspekt der Erfindung bei dem eingangs genannten Behälter dadurch gelöst, daß der Kunststoff-Kernbehälter mit eine metallische Schicht, beispielsweise aber nicht ausschließlich Aluminium, Stahl oder Kupfer überdeckt wird.According to one aspect of the invention, the object is achieved in the container mentioned at the outset in that the plastic core container is covered with a metallic layer, for example but not exclusively aluminum, steel or copper.

Diese Schicht kann auf der Innenseite des Kunststoff-Kernbehälters, und/oder als Zwischenlage im Kunststoffkernbehälter, und/oder als Außenlage auf den Kunststoffkernbehälter und/oder als Zwischenlage in dem Faserverbundwerkstoff integriert sein.This layer can be integrated on the inside of the plastic core container, and/or as an intermediate layer in the plastic core container, and/or as an outer layer on the plastic core container and/or as an intermediate layer in the fiber composite material.
