Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung einer flächenförmigen Kernmaterialbahn für Kernschichten von Sandwichverbundbauteilen. The invention relates to a device for producing a sheet-like core material web for core layers of sandwich composite components.
Ein Sandwichverbundbauteil ist eine Verbundplatte, die aus einem steifen oder flexiblen bzw. formbaren und schadenstoleranten Kern und zug- sowie druckfesten, steifen Deckschichten aufgebaut ist. Das Kernmaterial bzw. die Kernschicht wird dabei in der Regel zwischen zwei Deckschichten eingebracht, wodurch ein leichtes und trotzdem steifes Bauteil entsteht. Die Verbindung des Kernmaterials mit den Deckschichten kann, insbesondere mittels eines Vakuums über ein Harzinfusionsverfahren, Harzinjektionsverfahren oder auch über ein Handlaminierverfahren, insbesondere mittels Epoxidharz oder dergleichen erfolgen. A sandwich composite component is a composite panel constructed of a rigid or flexible or malleable and damage tolerant core and tension and compression resistant rigid cover layers. The core material or the core layer is usually introduced between two cover layers, whereby a lightweight, yet stiff component arises. The connection of the core material with the cover layers can be effected, in particular by means of a vacuum, via a resin infusion method, resin injection method or else via a hand lamination method, in particular by means of epoxy resin or the like.
Als Kernmaterialien kommen z. B. Schaumstoffe, Kork und/oder Balsaholz in Betracht. Diese werden üblicherweise auf ein Trägergewebe, beispielsweise ein Glasgewebe oder Glasgelege aufgebracht. Das Kernmaterial kann dazu aus einzelnen zueinander beabstandeten Segmenten mit rechteckigen oder quadratischen Formen mit dazwischen befindlichen Rillen oder dergleichen aufgebaut sein. Dadurch ergibt sich eine entsprechende Verformbarkeit der Sandwichverbundbauteile, z. B. zur Herstellung abgerundeter Formen und Konturen, wie etwa Flügeln von Windkraftanlagen. Der Herstellung derartiger Kernmaterialien ist jedoch relativ aufwändig. As core materials come z. As foams, cork and / or balsa wood into consideration. These are usually applied to a carrier fabric, for example a glass fabric or Glasgelege. The core material may for this purpose be composed of individual spaced-apart segments with rectangular or square shapes with intervening grooves or the like. This results in a corresponding deformability of the sandwich composite components, eg. B. for producing rounded shapes and contours, such as blades of wind turbines. However, the production of such core materials is relatively expensive.
Sandwichverbundbauteile bzw. -elemente finden u. a. Einsatz im Schiff- oder Bootsbau, Flugzeugbau, aber auch beispielsweise bei der Herstellung von Rotorblättern für Windkraftanlagen. Sandwich composite components or elements find u. a. Use in shipbuilding or boatbuilding, aircraft construction, but also, for example, in the manufacture of rotor blades for wind turbines.

Ausgehend davon liegt der vorliegenden Erfindung die Aufgabe zugrunde, eine Vorrichtung zur Herstellung einer flächenförmigen Kernmaterialbahn für Kernschichten von Sandwichverbundbauteilen der eingangs erwähnten Art zu verbessern, insbesondere effektiver und kostengünstiger zu gestalten. Proceeding from this, the present invention has the object to improve a device for producing a sheet-like core material web for core layers of sandwich composite components of the type mentioned above, in particular to make more effective and cost-effective.
Diese Aufgabe wird erfindungsgemäß durch Anspruch 1 gelöst. This object is achieved by claim 1.
Es wird ein Verfahren zur Herstellung einer flächenförmigen Kernmaterialbahn für Kernschichten von Sandwichverbundbauteilen, mit einer Trägergewebeschicht auf welche eine Kernmaterialschicht aufgebracht wird, wobei eine Trägergewebebahn schrittweise zugeführt und synchronisiert weitertransportiert wird, vorgeschlagen, wobei wenigstens:
- a) eine Klebeschicht auf die Trägergewebebahn aufgebracht oder eine bereits vorhandene Klebeschicht auf der Trägergewebebahn aktiviert wird, wonach
- b) wenigstens ein länglicher Kernmaterialblock von einer oberhalb der Trägergewebebahn angeordneten Kernmaterialzuführeinrichtung zugeführt und auf die mit der Klebeschicht versehene Trägergewebebahn aufgebracht wird, wonach
- c) der wenigstens eine aufgebrachte längliche Kernmaterialblock abgelängt wird, um eine vorgegebene Dicke des wenigstens einen aufgebrachten länglichen Kernmaterialblocks zur Bildung der Kernmaterialschicht auf der Kernmaterialbahn senkrecht zu der durch Trägergewebebahn aufgespannten Ebene zu erhalten, und wonach
- d) der wenigstens eine abgelängte, auf die Trägergewebebahn aufgebrachte längliche Kernmaterialblock angepresst wird.
- a) an adhesive layer applied to the carrier web or a already existing adhesive layer is activated on the carrier fabric web, after which
- b) at least one elongated core material block is fed from a core material feed device located above the carrier web and applied to the carrier web provided with the adhesive layer, after which
- c) the at least one deposited elongated core material block is cut to obtain a predetermined thickness of the at least one deposited elongated core material block for forming the core material layer on the core material web perpendicular to the plane defined by the carrier web and then
- d) the at least one cut to length, applied to the carrier fabric web elongated core material block is pressed.
Durch diese Maßnahmen wird die Herstellung einer flächenförmigen Kernmaterialbahn für Kernschichten von Sandwichverbundbauteilen wesentlich vereinfacht. Das Kernmaterial, beispielsweise Schaumstoff oder Balsaholz wird von oben durch eine Kernmaterialzuführeinrichtung auf die Trägergewebebahn aufgesetzt und entsprechend abgeschnitten. Danach wird die Trägerbahn weitertransportiert bzw. vorgetaktet. Anschließend fällt der nächste Bereich an Kernmaterial durch die Schwerkraft nach. Dabei kann es sich in vorteilhafter Weise um Platten oder Profile unterschiedlichster Art handeln. Die Stärke des Kernmaterials auf der Trägergewebebahn wird in einfacher Weise durch den Schnitt bestimmt. Zusätzlich wird eine Klebeschicht auf die Trägergewebebahn aufgebracht oder eine bereits vorhandene Klebeschicht auf der Trägergewebebahn aktiviert. Es können auch entsprechende Konturen auf der Kernmaterialbahn erstellt werden, indem das Kernmaterial modular zugeführt wird. Zudem können unterschiedliche Materialbreiten bei derselben Materialstärke realisiert werden. By these measures, the production of a sheet-like core material web for core layers of sandwich composite components is substantially simplified. The core material, such as foam or balsa wood is placed from above through a Kernmaterialzuführeinrichtung on the carrier web and cut accordingly. Thereafter, the carrier web is transported further or pre-clocked. Subsequently, the next area of nuclear material falls by gravity. This may advantageously be plates or profiles of various types. The thickness of the core material on the carrier web is easily determined by the cut. In addition, an adhesive layer is applied to the carrier web or activates an existing adhesive layer on the carrier web. It can also be created corresponding contours on the core material web by the core material is supplied modular. In addition, different material widths can be realized with the same material thickness.
Es kann ferner vorgesehen sein, dass nach dem Anpressen des wenigstens einen abgelängten, aufgebrachten länglichen Kernmaterialblocks auf die Trägergewebebahn:
- e) eine Trocknung der Kernmaterialbahn durchgeführt wird, wonach
- f) die Kernmaterialbahn seitlich besäumt wird, und wonach
- g) die Kernmaterialbahn aufgewickelt und entsprechend abgelängt wird.
- e) a drying of the core material web is carried out, after which
- f) the core material web is trimmed laterally, and after which
- g) the core material web is wound up and cut to length.
Beim Trocknungsvorgang kann die Klebeschicht aushärten und es entsteht eine feste Verbindung zwischen dem Kernmaterial und dem Trägergewebe. Durch das Besäumen können seitliche Überstände oder Kanten entfernt werden. Anschließend kann das Aufwickeln der Kernmaterialbahn in einer vorgegebenen Länge bzw. Stärke erfolgen. During the drying process, the adhesive layer can harden and there is a firm connection between the core material and the carrier fabric. By trimming lateral projections or edges can be removed. Subsequently, the winding of the core material web can take place in a predetermined length or thickness.
Der wenigstens eine längliche Kernmaterialblock kann von der oberhalb der Trägergewebebahn angeordneten Kernmaterialzuführeinrichtung wenigstens annähernd senkrecht zugeführt werden. The at least one elongated core material block can be supplied from the Kernmaterialzuführe arranged above the carrier web at least approximately perpendicular.
Mehrere längliche Kernmaterialblöcke können von der oberhalb der Trägergewebebahn angeordneten Kernmaterialzuführeinrichtung in einer Reihe oder in mehreren, insbesondere parallel nebeneinander angeordneten Reihen zugeführt werden. A plurality of elongated core material blocks can be supplied from the core material feed device arranged above the carrier fabric web in a row or in a plurality of rows arranged in particular parallel to one another.
Die Trägergewebebahn kann ein Glasgewebe oder Glasgelege aufweisen. The carrier fabric web may comprise a glass fabric or Glasgelege.
Das Kernmaterial kann bzw. die Kernmaterialblöcke können Holz niedriger Dichte, insbesondere Balsaholz, Kork und/oder Schaumstoff aufweisen. The core material or the core material blocks may have low-density wood, in particular balsa wood, cork and / or foam.
Des Weiteren kann die Kernmaterialbahn auch mit einer mitlaufenden Kordel versehen werden. Darüber hinaus könnten auch Versiegelungen oder dergleichen aufgebracht werden. Kernmaterialteile mit einer Schäftung bzw. abgeschrägten Enden können manuell angelegt werden. Furthermore, the core material web can also be provided with a revolving cord. In addition, seals or the like could be applied. Core material parts with a shank or bevelled ends can be created manually.
