Abstract

The container walls, made from composite fibre matrix, consist of adjacent mutually intersecting hemispherical segments (1) and the container corners and edges are made up of spherical segments (2) conforming to container surfaces. The opposing sides of the container are interconnected by an appropriate number of fibres (4) at the intervals formed by the intersecting spherical segments. One of the segments has a threaded opening (6) to take one or more valves. In detail, the first layer of the container is made of a required number of half and full segments as a coherent carbon fibre matrix whose opposing intervals (7) are joined by circumferential fibres. This layer is bonded at contact points with a second layer (5) and the two layers are inverted outwards for the valve opening (6).

Description

Druckbehälter kommen z. B. in der Verfahrenstechnik, im Fahrzeugbau und im Haushalt zur Hochdruckspeicherung von Gasen bzw. Flüssigkeiten zum Einsatz. Druckbehälter zur Hochdruckspeicherung sind in der Regel zylindrisch ausgeformt und an ihren Enden mit halbkugelförmigen Böden versehen. Sie bestehen meist aus geeigneten hochlegierten Stählen. In jüngster Zeit ist eine Entwicklung zu ebenfalls zylindrischen aber dünnwandigeren Stahl bzw. Aluminiumdruckbehältern zu beobachten, die mit einer stabilisierenden Wicklung aus Faserverbundwerkstoffen wie Glas- oder Kohlenstoffaser umgeben sind. Beide skizzierten Ausführungsarten verfügen in einem oder beiden Böden über ein Gewinde zur Einschraubung von geeigneten Ventilen.Pressure vessels come e.g. B. in process engineering, in vehicle construction and in the household High pressure storage of gases or liquids for use. Pressure vessel for High-pressure accumulators are usually cylindrical and have ends at them hemispherical bottoms. They usually consist of suitable high-alloy steels. In recent times there has been a development towards also cylindrical but thin-walled steel or aluminum pressure vessels with a stabilizing winding Fiber composite materials such as glass or carbon fiber are surrounded. Both outlined Design types have a thread for screwing in one or both shelves of suitable valves.

Dabei sind aber zylindrische Druckbehälter den Platzverhältnissen ihrer anwendungsbedingten Umgebung oft nur schlecht anzupassen. Das heißt nur über eine entsprechende Anzahl von kleineren Behältern in Verbindung mit einem entsprechend höheren Gewicht läßt sich eine ökonomische Raumausnutzung erreichen. Zur optimalen Raumausnutzung notwendige nichtzylindrische Druckbehälter zur Hochdruckspeicherung sind bis heute auf Grund der ungünstigen statischen Belastungen durch Druck auf Flächen nicht üblich. So lassen sich auf Grund der bereits aufgeführten ungünstigen statischen Verhältnisse nichtzylindrische Druckbehälter nur mit unverhältnismäßig dicken Wandungsstärken betriebssicher auslegen, was ein unverhältnismäßig hohes Gewicht zur Folge hat. Bei der Verwendung von Stahl für solche Behälter kommt es außerdem zu Problemen bezüglich der Verbindung der Flächen untereinander und der Bearbeitung.But cylindrical pressure vessels are the space available for their application Environment often difficult to adapt. That means only over a corresponding number of smaller containers in connection with a correspondingly higher weight can be achieve economical use of space. Necessary for optimal use of space Non-cylindrical pressure vessels for high-pressure storage are still due to the unfavorable static loads caused by pressure on surfaces are not common. So let's get on Due to the unfavorable static conditions already mentioned, non-cylindrical Only design pressure vessels with disproportionately thick walls in a reliable manner, which results in a disproportionate weight. When using steel for such containers also have problems with the connection of the surfaces among themselves and processing.

Der im Patentanspruch angegebenen Erfindung liegt das Problem zu Grunde, einen die optimalen Raumausnutzung ermöglichenden Druckbehälter zu schaffen, der bei gleichbleibend dünner Wandungsstärke und geringem Gewicht hohen Drücken standhält.The invention specified in the claim is based on the problem, the one To create optimal use of space to create pressure vessels that remain the same with thin walls and low weight withstands high pressures.

Dieses Problem wird durch die im Patentanspruch aufgeführten Merkmale gelöst.This problem is solved by the features listed in the claim.

Die Vorteile eines erfindungsgemäßer nichtzylindrischer Verbundstoffdruckbehälters bestehen insbesondere darin, daß durch die Gestaltung der Behälterwandungen in dem jeweiligen Kugelsegment eine gleichmäßige Kräfteverteilung des anstehenden Drucks gewährleistet wird. Dadurch kann die aus Verbundfasermatrix bestehende Wandung der Kugelsegmente gleichmäßig dünn gestaltet und damit das Behältergewicht relativ zur möglichen Druckaufnahme gering gehalten werden. Jeweils zwei gegenüberliegende Kugelsegmente bilden ein Modul, in dem durch die Verbindung der beiden Kugelsegmente mittels der vier Faserstränge ein Kräftegleichgewicht herrscht. Das Kräftegleichgewicht in dem jeweiligen Modul ermöglicht eine beliebige Aneinanderreihung dieser Module und damit eine beliebige Gestaltung der Behälterform und Größe. Damit wird bei geringem Platzbedarf eine optimale Anpassung der Behälterform an die Umgebungsanforderungen ermöglicht. Die lediglich auf Zug belasteten Faserstränge können dementsprechend aufgabengemäß dünn dimensioniert werden und schränken dadurch bei geringem Materialgewicht das nutzbare Behältervolumen nur unwesentlich ein. The advantages of a non-cylindrical composite pressure vessel according to the invention exist especially in that by the design of the container walls in the respective Ball segment a uniform distribution of forces of the pressure is guaranteed. This allows the wall of the spherical segments consisting of a composite fiber matrix designed evenly thin and thus the container weight relative to the possible Pressure absorption can be kept low. Two opposing spherical segments each form a module in which by connecting the two spherical segments by means of the four Fiber strands there is a balance of forces. The balance of forces in the respective Module enables any combination of these modules and thus any one Design of the container shape and size. This makes an optimal one with a small footprint Adaptation of the container shape to the environmental requirements. The only on Accordingly, fiber strands subject to tensile stress can be thinly dimensioned according to the task and thus limit the usable container volume with a low material weight only insignificant.

In Fig. 1 ist ein Teilschnitt durch einen erfindungsgemäßen nichtzylindrischen Druckbehälter in Faserverbundtechnik dargestellt.In Fig. 1 a partial section through an inventive non-cylindrical pressure vessel in fiber composite technology.

Die Behälterwandung besteht aus einer geeigneten Anzahl von Halbkugel- (1) bzw. Eckkugel­ segmenten (2). Die Kugelsegmente bestehen aus einer ersten Lage (3) zusammenhängender Kohlenstoffasermatrix. Dabei sind jeweils die beiden gegenüberliegenden Zwischenräume (7), die sich durch die überschneidenden Kugelsegmente ergeben, durch eine geeignete Anzahl umlaufender Kohlenstoffasern (4) miteinander verbunden. Die erste Lage (3) Kohlenstoff­ fasermatrix, sowie die die gegenüberliegenden Seiten verbindenden Kohlenstoffasern sind mit einer zweiten Lage (5) Kohlenstoffasermatrix an den sich berührenden Flächen durch geeignetes Harz verbunden. In einem der Kugelsegmente ergeben die beiden nach außen gestülpten Lagen (3 u. 5) von Kohlenstoffasermatrix die Gewindebohrung (6) zur Ventil­ aufnahme.The container wall consists of a suitable number of hemisphere ( 1 ) or corner ball segments ( 2 ). The spherical segments consist of a first layer ( 3 ) of connected carbon fiber matrix. The two opposite gaps ( 7 ), which result from the overlapping spherical segments, are connected to one another by a suitable number of circumferential carbon fibers ( 4 ). The first layer ( 3 ) of carbon fiber matrix and the carbon fibers connecting the opposite sides are connected to a second layer ( 5 ) of carbon fiber matrix on the contacting surfaces by a suitable resin. In one of the spherical segments, the two layers ( 3 and 5 ) of carbon fiber matrix turned outwards result in the threaded bore ( 6 ) for the valve holder.
