Description

Die Erfindung betrifft einen Druckbehälter zum Speichern eines Fluides, welcher mit einem Kunststofflcernbehälter und einem auf den Kunststoffkernbehälter aufgebrachten Außenmantel gebildet ist.The invention relates to a pressure vessel for storing a fluid, which is formed with a Kunststofflcernbehälter and an applied on the plastic core container outer shell.

Hintergrund der ErfindungBackground of the invention

Derartige Druckbehälter dienen zum Speichern flüssiger oder gasförmiger Medien, also Fluiden, die druckbelastet sind. Druckbehälter dieser Art sind beispielsweise aus den folgenden Dokumenten bekannt: DE 10 2006 001 052 A1 , DE 10 2006 043 582 B3 sowie DE 10 2007 011 211 B3 .Such pressure vessels are used for storing liquid or gaseous media, ie fluids that are pressure-loaded. Pressure vessels of this type are known, for example, from the following documents: DE 10 2006 001 052 A1 . DE 10 2006 043 582 B3 such as DE 10 2007 011 211 B3 ,

Es wurde vorgeschlagen, bei solchen Druckbehältern im Bereich sogenannter Polkappen, nämlich im Übergangsbereich zwischen Stirnseite und Umfang des Kunststoffkernbehälters, mit stoß- oder fallabsorbierenden Schutzelementen anzuordnen. Auf diese Weise sollen ungewünschte Schädigungen an dem Druckbehälter vermieden werden, wenn dieser umgestoßen wird oder herunterfällt. Hierbei soll der Schutz insbesondere bei einem Aufprallwinkel von etwa 45° zur Längsachse des Druckbehälters ausgebildet sein. Als Aufprall- oder Stoßschutz wurden Schutzkappen aus Kunststoffmaterial im Bereich der Polkappen vorgeschlagen (vgl. DE 197 51 411 C1 sowie US 5,476,189 ).It has been proposed to arrange with such pressure vessels in the region of so-called polar caps, namely in the transition region between the front side and the circumference of the plastic core container, with impact-absorbing or fall-absorbing protective elements. In this way, undesired damage to the pressure vessel should be avoided if it is knocked over or falls down. In this case, the protection should be formed in particular at an impact angle of about 45 ° to the longitudinal axis of the pressure vessel. Protective caps made of plastic material in the area of the polar caps have been proposed as impact or impact protection (cf. DE 197 51 411 C1 such as US 5,476,189 ).

Weiterhin ist ein Druckbehälter aus dem Dokument US 5,429,845 bekannt.Furthermore, a pressure vessel from the document US 5,429,845 known.

Aus dem Dokument US 5,018,638 ist ein Druckbehälter mit einem Kernbehälter aus Aluminium bekannt. Auf den Aluminiumbehälter ist eine äußere Armierung mit mehreren gewickelten Faserlagen aufgebracht. In einer Ausführung verdicken sich gewickelte Lagen vom Umfangsbereich ausgehend zur Stirnseite des Druckbehälters hin, wobei die maximale Verdickung an dem auf der Stirnseite des Druckbehälters angeordneten Ende erreicht ist.From the document US 5,018,638 a pressure vessel with a core container made of aluminum is known. On the aluminum container, an outer reinforcement is applied with several wound fiber layers. In one embodiment, wound layers thicken from the peripheral region towards the front side of the pressure vessel, the maximum thickening being reached at the end arranged on the front side of the pressure vessel.

Im Dokument EP 0 666 450 A1 ist ein Druckbehälter offenbart, welcher einen aus einem Kunststoff bestehenden Liner mit einem zylindrischen Mittelteil und zwei kalottenförmigen Endteilen aufweist. Der Liner wird von einem Außenmantel umhüllt, der mehrere in radialer Richtung übereinander angeordnete Tangentialwicklungen und Axialwicklungen aus einem faserverstärkten Kunststoff aufweist.In the document EP 0 666 450 A1 discloses a pressure vessel having a liner made of a plastic having a cylindrical central portion and two dome-shaped end portions. The liner is sheathed by an outer sheath, several in radial Direction superposed tangential windings and axial windings of a fiber-reinforced plastic.

Die Druckschrift DE 103 45 159 A1 betrifft einen Hochdrucktank, bei dem eine Zwischenfaserschicht sich von der Umfangseite ausgehend über den Polkappenbereich bis hin zur stirnseitigen Öffnung verdickt.The publication DE 103 45 159 A1 relates to a high-pressure tank in which an intermediate fiber layer thickening from the peripheral side over the pole cap area thickened up to the frontal opening.

Im Dokument US 2008 / 0111322 A1 ist ein Druckbehälter offenbart, bei dem im Polkappenbereich außenseitig Stoßschutzelemente aufgebracht sind. Eine den inneren Liner umhüllende Außenschicht verdickt sich vom Umfang des Liners ausgehend zunehmend bis zur stirnseitigen Öffnung hin.In the document US 2008/0111322 A1 a pressure vessel is disclosed in which impact protection elements are applied on the outside in the pole cap area. An outer layer enveloping the inner liner thickens progressively from the circumference of the liner to the frontal opening.

Auch beim Druckbehälter im Dokument US 4,438 858 verdicken sich gewickelte Faserlagen zur stirnseitigen Behälteröffnung hin, wobei die Verdickung benachbart zur stirnseitigen Behälteröffnung am größten ist.Also with the pressure vessel in the document US 4,438,858 Thickened fiber layers thicken toward the front-side container opening, wherein the thickening adjacent to the front-side container opening is greatest.

Zusammenfassung der ErfindungSummary of the invention

Aufgabe der Erfindung ist es, einen verbesserten Druckbehälter zum Speichern eines Fluides mit einem Kunststoffkernbehälter und einem auf den Kunststoffkernbehälter aufgebrachten Außenmantel zu schaffen, bei dem ein Aufprall- und Stoßschutz auf eine fertigungstechnisch einfach herstellbare Art und Weise ausbildbar ist.The object of the invention is to provide an improved pressure vessel for storing a fluid with a plastic core container and an outer shell applied to the plastic core container, in which an impact and impact protection can be formed in a manufacturing technology easily manufacturable manner.

Diese Aufgabe wird erfindungsgemäß durch einen Druckbehälter zum Speichern eines Fluides nach dem unabhängigen Anspruch 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand von abhängigen Unteransprüchen.This object is achieved by a pressure vessel for storing a fluid according to independent claim 1. Advantageous embodiments of the invention are the subject of dependent subclaims.

Der vorgeschlagene Druckbehälter hat gegenüber dem Stand der Technik insbesondere den Vorteil, dass die Ausbildung des Stoß- und Aufprallschutzes im Bereich der Polkappen und wahlweise benachbart hierzu bei der Herstellung der faserverstärkten Armierungen stattfindet, als beim Herstellen der gewickelten Lagen. Es ist im Vergleich zum Stand der Technik nicht notwendig, in weiteren Herstellungsschritten zusätzlich Kunststoffelemente, beispielsweise geschäumte Kunststoffelemente, in den Außenmantel einzuarbeiten. Auf diese Weise wird der Herstellungsprozess für den Druckbehälter optimiert. Die stoßabsorbierende Armierungsverdickung erhöht die Wandstärke im zylindrischen Bereich des Druckbehälters. Hierdurch wird die Robustheit des Systems erhöht.The proposed pressure vessel has over the prior art in particular the advantage that the formation of shock and impact protection in the pole caps and optionally adjacent thereto in the production of fiber-reinforced reinforcements takes place, as in the manufacture of the wound layers. In comparison with the prior art, it is not necessary to additionally incorporate plastic elements, for example foamed plastic elements, into the outer jacket in further production steps. In this way, the manufacturing process for the pressure vessel is optimized. The shock-absorbing Armierungsverdickung increases the wall thickness in the cylindrical portion of the pressure vessel. This increases the robustness of the system.

Die erste faserverstärkte Armierung kann in einer Ausgestaltung ausschließlich mit den ersten Fasern gebildet sein. Alternativ oder ergänzend kann eine Ausgestaltung vorsehen, dass in der zweiten faserverstärkten Armierung ausschließlich die zweiten Fasern verwendet werden. Das erste und das zweite Matrixmaterial können gleich oder verschieden sein.

Auf einen Kunststoffkernbehälter 1, welcher auch als Liner bezeichnet wird, ist in einem Umfangsbereich 2 eine aus ersten Fasern gewickelte Umfangslage 3 aufgebracht. Bei der dargestellten Ausführungsform werden als erste Fasern Kohlefasern verwendet, die mit einem Winkel zwischen etwa 60° und etwa 90° zur Längsachse des Druckbehälters aufgewickelt sind.The single FIGURE shows a section of a pressure vessel for storing a fluid, so a gas or a liquid, in cross section. On a plastic core container 1, which is also referred to as a liner, a peripheral layer 3 wound from first fibers is applied in a peripheral region 2. In the illustrated embodiment, carbon fibers are used as the first fibers, which are wound at an angle between about 60 ° and about 90 ° to the longitudinal axis of the pressure vessel.

Die ersten Fasern der Umfangslage 3 sind in ein Matrixmaterial eingebettet, bei dem es sich um ein thermoplastisches oder duroplastisches Harzsystem handelt. Das Einbetten der gewickelten Fasern in das Matrixmaterial wird auch als Imprägnieren bezeichnet. Für die im Folgenden beschriebenen, weiteren gewickelten Lagen aus Fasern kann ein gleiches oder ein von dem Matrixmaterial der Umfangslage 3 verschiedenes Matrixmaterial eingesetzt werden, wobei auch hier thermoplastische oder duroplastische Harzsysteme zum Einsatz kommen.The first fibers of the peripheral layer 3 are embedded in a matrix material which is a thermoplastic or thermosetting resin system. The embedding of the wound fibers in the matrix material is also referred to as impregnation. For the further wound layers of fibers described below, it is possible to use a matrix material which is the same or different from the matrix material of the circumferential layer 3, wherein thermoplastic or thermosetting resin systems are also used here.

Die Umfangslage 3 ist Bestandteil einer ersten faserverstärkten Armierung 4, die auf den Kunststoffkernbehälter 2 aufgebracht ist. Bei dem dargestellten Ausführungsbeispiel bildet die erste faserverstärkte Armierung 4 zusammen mit einer zweiten faserverstärkten Armierung 5, die auf die erste faserverstärkte Armierung 4 aufgebracht ist, einen Außenmantel 6 auf dem Kunststofflcernbehälter 2.The peripheral layer 3 is part of a first fiber-reinforced reinforcement 4, which is applied to the plastic core container 2.
