Abstract
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Druckbehälters, insbesondere für ein Kraftfahrzeug, insbesondere als Drucktank für Wasserstoff, nach dem Oberbegriff des ersten Anspruchs.The invention relates to a method for producing a pressure vessel, in particular for a motor vehicle, in particular as a pressure tank for hydrogen, according to the preamble of the first claim.
Es ist bereits bekannt, Wasserstoff als Kraftstoff für Kraftfahrzeuge zu verwenden und diesen dazu in einem Drucktank unter Überdruck zu speichern. Derartige Drucktanks können aus Stahl bestehen. Für einen höheren Fülldruck kann zum Beispiel ein solcher, im wesentlichen zylindrischer Stahltank durch einen Faserverbundwerkstoff mit beispielsweise Glas- und/oder Kohlenstofffasern umwickelt werden.It is already known to use hydrogen as a fuel for motor vehicles and to store this in a pressure tank under pressure. Such pressure tanks can be made of steel. For example, for a higher inflation pressure, such a substantially cylindrical steel tank may be wrapped by a fiber composite with, for example, glass and / or carbon fibers.
Ein solcher Druckbehälter ist aus der
Wird also der Druckbehälter durch seinen Inhalt bedruckt, wird zunächst eine Druckvorspannung im Liner aus der Autofrettage ausgeglichen und erst bei weiter ansteigendem Innendruck die Behälterwandung nach außen hin auf Zug beansprucht.Thus, if the pressure vessel is printed by its contents, first a pressure bias in the liner from the autofrettage is compensated and only when the internal pressure continues to increase does the container wall become stressed towards the outside.
Da es sich beim Innendruck um eine intensive Zustandsgröße handelt, ergibt sich das resultierende Verhältnis von Längs- und Quervorspannung aus dem Lagenaufbau des aufgebrachten Faserverbundes. Da dieser jedoch auf die Betriebslasten Druck und/oder Temperatur und nicht auf den Autofrettageprozess ausgelegt ist, können sich ungünstige Vorspannungsverhältnisse einstellen. Außerdem kann es beim Betrieb unter kryogenen Temperaturen in drucklosen oder -armen Betriebsfällen dazu kommen, dass die Faserverbundarmierung aufgrund mangelnder Vorspannung in Tanklängsrichtung den Kontakt zum metallischen Liner und somit ihre verstärkende Wirkung verliert. Insbesondere können hiervon die Dome des Druckbehälters betroffen sein.Since the internal pressure is an intensive state variable, the resulting ratio of longitudinal and transverse prestress results from the layer structure of the applied fiber composite. However, since this is designed for the operating loads pressure and / or temperature and not on the Autofrettageprozess, unfavorable bias conditions can be adjusted. Moreover, when operating under cryogenic temperatures in non-pressurized or low-operating conditions, it may happen that the Faserverbundarmierung loses contact with the metallic liner and thus their reinforcing effect due to lack of bias in tank longitudinal direction. In particular, this may affect the dome of the pressure vessel.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Druckbehälters der eingangs genannten Art so weiter zu entwickeln, dass dieses obige Nachteile vermeidet und mit dem gezielt die Vorspannungszustände eines Druckbehälters unabhängig vom Aufbau des zur Verstärkung aufgebrachten Faserverbundwerkstoffes beeinflusst werden können.The invention is therefore based on the object to develop a method for producing a pressure vessel of the type mentioned so that this avoids the above disadvantages and can be influenced with the targeted the bias conditions of a pressure vessel regardless of the structure of the applied for reinforcement fiber composite material.
Die Aufgabe wird durch die Merkmale und Verfahrensschritte des ersten Anspruchs gelöst. Bevorzugte Ausgestaltungen der Erfindung beschreiben die abhängigen Ansprüche.The object is achieved by the features and method steps of the first claim. Preferred embodiments of the invention describe the dependent claims.
Bei einem Verfahren nach der Erfindung wird ein Druckbehälter aus einem metallischen Liner hergestellt, indem dieser außen mit Faserverbundwerkstoff verstärkt und nach dem Aushärten des Matrixwerkstoffes einer Autofrettage-Behandlung unterworfen wird. Die Erfindung zeichnet sich dadurch aus, dass vor dem Aufbringen des Faserverbundwerkstoffes auf den Liner, dieser in Längsrichtung bis nach dem Aushärten des Matrixwerkstoffes vorgespannt wird.In a method according to the invention, a pressure vessel is made of a metallic liner by reinforcing it externally with fiber composite material and subjecting it to autofrettage treatment after curing of the matrix material. The invention is characterized in that prior to the application of the fiber composite material to the liner, this is biased in the longitudinal direction until after the curing of the matrix material.
Das Verhältnis aus der Vorspannung in Längs- und Umfangsrichtung des Druckbehälters lässt sich hierdurch gezielt beeinflussen und so unabhängig vom Aufbau der Faserverbundummantelung einstellen. Damit ermöglicht das erfinderische Verfahren, die Spannungsverhältnisse am Druckbehälter gezielt zu beeinflussen, indem der Liner bereits vor dem Aufbringen des Faserverbundes in seiner Längsachse gestaucht wird. Dadurch kann die Vorspannung in Tanklängsrichtung zum einen sehr genau eingestellt werden und zum anderen im Betrag höher liegen als durch eine plastische Verformung des Liners. Es lässt sich auch der Effekt des Ablösens der Faserverbundarmierung vermeiden, zu dem es beim Betrieb unter kryogenen Temperaturen in drucklosen oder -armen Betriebsfällen kommen kann. Hier verliert die Faserverbundarmierung aufgrund mangelnder Vorspannung in Tanklängsrichtung den Kontakt zum metallischen Liner und somit ihre verstärkende Wirkung. Der Effekt der Autofrettage wird verstärkt in seiner Wirkung in Längsrichtung durch die Erhöhung der Vorspannung in dieser Richtung.The ratio of the bias in the longitudinal and circumferential direction of the pressure vessel can be selectively influenced and thus set independently of the structure of the fiber composite casing. Thus, the inventive method allows to influence the voltage conditions on the pressure vessel targeted by the liner is already compressed before applying the fiber composite in its longitudinal axis. As a result, the preload in the tank longitudinal direction can be set very precisely for one thing and, on the other hand, are higher in amount than by a plastic deformation of the liner. It can also be the effect of removing the Faserverbundarmierung avoid, which when operating under cryogenic temperatures can come in unpressurized or poor operating conditions. Here the Faserverbundarmierung loses contact with the metallic liner and thus its reinforcing effect due to lack of bias in tank longitudinal direction. The effect of Autofrettage is reinforced in its longitudinal action by increasing the bias in this direction.
Bevorzugte Ausführungen der Erfindung sehen vor, dass der Faserverbundwerkstoff aus Kohlenstofffasern und/oder Glasfasern besteht, dabei kann der Matrixwerkstoff ein duroplastischer oder ein thermoplastischer Kunststoff sein. Und vorteilhafterweise ist der Druckbehälter ein Typ 3 Druckbehälter, das heißt, ein komplett umwickelter metallischer Zylinder mit einem Dom auf jeder Seite. Die Verstärkungsfasern werden bevorzugt mittels aus dem Stand der Technik bekannter Verfahren, dem Wickel- oder dem Flechtverfahren oder auch mittels Resin Transfer Moulding aufgebracht. Beispielsweise kann die benötigte Stauchung des Liners mittels einer zwischen beide Anschlussöffnungen gespannten Gewindestange aufgebracht werden. Wichtig dabei ist, dass die künstlich aufgebrachte Vorspannung auch während des Aushärteprozesses des Faserverbundes aufrecht erhalten bleibt um ein Verrutschen der Fasern und damit den Verlust der Vorspannung zu vermeiden.Preferred embodiments of the invention provide that the fiber composite material consists of carbon fibers and / or glass fibers, while the matrix material may be a thermosetting or a thermoplastic plastic. And advantageously, the pressure vessel is a
Eine weitere bevorzugte Ausführung der Erfindung betrifft ein Kraftfahrzeug, das dadurch gekennzeichnet ist, dass es mit einem Drucktank, insbesondere für Wasserstoff, ausgestattet ist, der nach einem erfindungsgemäßen Verfahren hergestellt ist.A further preferred embodiment of the invention relates to a motor vehicle, which is characterized in that it is equipped with a pressure tank, in particular for hydrogen, which is produced by a method according to the invention.
Das erfindungsgemäße Verfahren ist in der nachfolgenden Beschreibung und der zugehörigen Zeichnung näher dargestellt. Dazu zeigen die schematisch gezeichneten
In
Wird ein Kraftfahrzeug mit einem solchen Druckbehälter für Wasserstoff ausgestattet, besitzt dieser aufgrund der Autofrettage-Behandlung ein vorteilhaft geringes Gewicht und wird durch die Erhöhung der Vorspannung in Längsrichtung mittels gezielter Umwicklung mit Faserverbundwerkstoff im gestauchten Zustand auch bei kryogen-kalten Temperaturen davor bewahrt, dass an den Domen
Vorzugsweise wird ein derartiger Druckbehälter in Kraftfahrzeugen zum Mitführen von Wasserstoff als Kraftstoff eingesetzt. Grundsätzlich können derartig ausgebildete Druckbehälter aber auch auf allen anderen Gebieten der Technik eingesetzt werden, beispielsweise als stationärer Vorratsbehälter zur Energiegewinnung in einer Brennstoffzelle. Auch können bei geeigneter Materialwahl andere Gase eingefüllt werden.Preferably, such a pressure vessel is used in motor vehicles for carrying hydrogen as fuel. In principle, however, pressure vessels formed in this way can also be used in all other fields of technology, for example as a stationary reservoir for the generation of energy in a fuel cell. Also, other gases can be filled with a suitable choice of material.
