Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung eines Faserverbundbauteils, bei welchem ein löslicher Formkern (9) mit Fasern umgeben wird und danach eine Matrix ausgehärtet wird, wonach der Formkern (9) aus dem Faserverbundkörper (5) entfernt wird. Bei einem Verfahren, mit welchem ein Faserverbundbauteil erzeugt wird, das möglichst überall in seiner Stabilität an die gestellten Anforderungen angepasst und trotzdem gewichtsoptimiert ist, wird der Formkern (9) in einem generativen Verfahren hergestellt, wobei der Formkern (9) derart aus unterschiedlichen Materialien (7, 11) gebildet wird, dass an Stellen des herzustellenden Faserverbundbauteils (1), die eine höhere Stabilität erfordern, ein unlösliches (11) und an Stellen, an denen eine geringere Stabilität erforderlich ist, ein lösliches Material (7) verwendet wird, und dass der Formkern (9) mit Fasern und einer Kunststoffmatrix umgeben wird, wobei anschließend die Kunststoffmatrix ausgehärtet wird und nach der Aushärtung das lösliche Material (7) des Formkerns (9) aus dem Faserverbundkörper (5) heraus gelöst wird.The invention relates to a method for producing a fiber composite component in which a soluble mold core (9) is surrounded by fibers and a matrix is then cured, after which the mold core (9) is removed from the fiber composite body (5). In a method with which a fiber composite component is produced, the stability of which is adapted to the requirements as far as possible and which is nevertheless weight-optimized, the mold core (9) is produced in a generative process, the mold core (9) being made of different materials 7, 11) that an insoluble material (11) is used at points of the fiber composite component (1) to be produced which require greater stability and a soluble material (7) is used at points at which lower stability is required, and that the mold core (9) is surrounded with fibers and a plastic matrix, the plastic matrix then being hardened and, after hardening, the soluble material (7) of the mold core (9) being released from the fiber composite body (5).
Description
Die Erfindung betrifft ein Verfahren zur Herstellung eines Faserverbundbauteils, bei welchem ein löslicher Formkern mit Fasern umgeben wird und danach eine Matrix ausgehärtet wird, wonach der Formkern aus dem Faserverbundkörper entfernt wird.The invention relates to a method for producing a fiber composite component in which a soluble mold core is surrounded with fibers and a matrix is then cured, after which the mold core is removed from the fiber composite body.
Aus der
Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung eines Faserverbundbauteils anzugeben, mit welchem ein Faserverbundbauteil erzeugt wird, das möglichst überall in seiner Stabilität an die gestellten Anforderungen angepasst und trotzdem gewichtsoptimiert ist.The object of the invention is to provide a method for producing a fiber composite component, with which a fiber composite component is produced which, as far as possible, is adapted to the requirements in terms of its stability and is nevertheless weight-optimized.
Die Erfindung ergibt sich aus den Merkmalen der unabhängigen Ansprüche. Vorteilhafte Weiterbildungen und Ausgestaltungen sind Gegenstand der abhängigen Ansprüche. Weitere Merkmale, Anwendungsmöglichkeiten und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, sowie der Erläuterung von Ausführungsbeispielen der Erfindung, die in den Figuren dargestellt sind.The invention results from the features of the independent claims. The dependent claims relate to advantageous developments and refinements. Further features, possible applications and advantages of the invention emerge from the following description and the explanation of exemplary embodiments of the invention which are shown in the figures.
Die Aufgabe ist mit einem Verfahren dadurch gelöst, dass der Formkern in einem generativen Verfahren hergestellt wird, wobei der Formkern derart aus unterschiedlichen Materialien gebildet wird, dass an Stellen des herzustellenden Faserverbundbauteils, die eine höhere Stabilität erfordern, ein unlösliches und an Stellen, an denen eine geringere Stabilität erforderlich ist, ein lösliches Material verwendet wird, und dass der Formkern mit Fasern und einer Kunststoffmatrix umgeben wird, wobei anschließend die Kunststoffmatrix ausgehärtet wird und nach der Aushärtung das lösliche Material des Formkerns aus dem Faserverbundkörper heraus gelöst wird. Dies hat den Vorteil, dass der Formkern nur an den Positionen im Faserverbundkörper verbleibt, wo es die Stabilität des Faserverbundbauteils erfordert. Dadurch wird das Gewicht des Faserverbundbauteils reduziert. Der Formkern verbleibt nur an den Stellen, wo er hinsichtlich der Stabilität des Faserverbundbauteiles in dessen Endnutzung auch wirklich gebraucht wird und die Faserverbundschichten auf Abstand hält.The object is achieved with a method in that the mold core is produced in a generative process, the mold core being formed from different materials in such a way that at points of the fiber composite component to be produced that require greater stability, an insoluble component and at points where a lower stability is required, a soluble material is used, and that the mold core is surrounded with fibers and a plastic matrix, the plastic matrix then being hardened and, after hardening, the soluble material of the molding core is released from the fiber composite body. This has the advantage that the mold core only remains in the positions in the fiber composite body where the stability of the fiber composite component requires it. This reduces the weight of the fiber composite component. The mold core only remains in the places where it is really needed with regard to the stability of the fiber composite component in its end use and where it keeps the fiber composite layers at a distance.
Vorteilhafterweise wird als generatives Verfahren ein 3D-Druckverfahren eingesetzt. Das 3D-Druckverfahren erlaubt einen hybriden Material-Strukturaufbau, z.B. einen SandwichAufbau des Formkerns, wodurch Eigenschaften des Faserverbundbauteils hinsichtlich Gewicht und Stabilität verbessert werden können.A 3D printing process is advantageously used as the generative process. The 3D printing process allows a hybrid material structure, e.g. a sandwich structure of the mold core, whereby properties of the fiber composite component can be improved in terms of weight and stability.
In einer Ausgestaltung wird als lösliches Material ein Kunststoff verwendet. Kunststoff ist leicht, weist aber eine hohe Stabilität auf.In one embodiment, a plastic is used as the soluble material. Plastic is light, but has a high degree of stability.
In einer Variante wird das lösliche Material des Formkerns ausgeschwemmt. Das Ausschwemmen stellt eine prozesstechnisch einfaches Verfahren dar.In a variant, the soluble material of the mold core is flushed out. Flushing out is a simple process in terms of process technology.
Weitere Vorteile, Merkmale und Einzelheiten ergeben sich aus der nachfolgenden Beschreibung, in der - gegebenenfalls unter Bezug auf die Zeichnung - zumindest ein Ausführungsbeispiel im Einzelnen beschrieben ist. Beschriebene und/oder bildlich dargestellte Merkmale können für sich oder in beliebiger, sinnvoller Kombination den Gegenstand der Erfindung bilden, gegebenenfalls auch unabhängig von den Ansprüchen, und können insbesondere zusätzlich auch Gegenstand einer oder mehrerer separater Anmeldung/en sein. Gleiche, ähnliche und/oder funktionsgleiche Teile sind mit gleichen Bezugszeichen versehen.Further advantages, features and details emerge from the following description in which at least one exemplary embodiment is described in detail - possibly with reference to the drawing. Described and / or graphically represented features can form the subject matter of the invention individually or in any meaningful combination, optionally also independently of the claims, and in particular can also be the subject matter of one or more separate applications. Identical, similar and / or functionally identical parts are provided with the same reference symbols.
