Die in Fig. 1 dargestellte Leichtbauplatte besitzt eine Kernplatte 1 vorgegebener Dicke, welche in Form einer Wabenstruktur aus Aluminium oder Nomexpapier ausgebildet ist* Beidseitig von dieser Kernplatte 1 sind dünne Aüßenplätten 2 und 3 aufgesetzt, welche beispielsweise aus Aluminiumblech oder einem entsprechend nmpra«*- nierten Nomexpapier bestehen. Die Verbindung der drei Platten 1, 2 und 3 untereinander erfolgt im Rahmen der vorliegenden Erfindung mit Hilfe eines Klebemittels 4 aus einem thermoplastischen Harz, welches beispielsweise aus einem Polyamid, einem Pölyimid, einem Polyäthersulfon (PES) oder einem Polyätherimid (PEI), bestehen kann. Bei diesen Klebemitteln 4 handelt es sich dabei um Klebstoffe, mit welchen eine kohasive Verklebung erreicht werden kann.The lightweight panel shown in Fig. 1 has a core panel 1 of a predetermined thickness, which is designed in the form of a honeycomb structure made of aluminum or Nomex paper. On both sides of this core panel 1 are placed thin outer panels 2 and 3, which consist for example of aluminum sheet or a correspondingly coated Nomex paper. The connection of the three panels 1, 2 and 3 to one another takes place within the scope of the present invention with the aid of an adhesive 4 made of a thermoplastic resin, which can consist for example of a polyamide, a polyimide, a polyethersulfone (PES) or a polyetherimide (PEI). These adhesives 4 are adhesives with which a cohesive bond can be achieved.

Während bei der Ausführungsform in Fig. 1 das eine kohäsive Verklebung bewirkende Klebemittel 4 relativ dick an den Rändern der eine Wabenstruktur aufweisenden Kernplatte 1 aufgebracht ist, ist bei der in Fig. 2 dargestellten Ausführungsform das betreffende Klebemittel 4 dünnflächig auf der gesamten Oberfläche der eine Wabenstruktur aufweisenden Kernplatte 1 aufgebracht, so daß je nach der Art der Aufbringung unterschiedliche mechanische Festigkeiten der jeweiligen Leichtbauplatte erzielbar sind.While in the embodiment in Fig. 1 the adhesive 4 which causes a cohesive bond is applied relatively thickly on the edges of the core plate 1 having a honeycomb structure, in the embodiment shown in Fig. 2 the adhesive 4 in question is applied thinly over the entire surface of the core plate 1 having a honeycomb structure, so that depending on the type of application, different mechanical strengths of the respective lightweight panel can be achieved.

Die Herstellung der in den Figuren 1 und 2 dargestellten Leichtbauplatte wird wie folgt vorgenommen:The lightweight panel shown in Figures 1 and 2 is manufactured as follows:

Bei Verwendung einer Kernplatte 1 aus einem Aluminium-Wabenkörper wird derselbe zuerst entfettet und, falls erforderlich, geätzt. In der Folge wird dann auf den betreffenden Wabenkörper durch Aufsprühen oder örtlichesWhen using a core plate 1 made of an aluminum honeycomb body, the same is first degreased and, if necessary, etched. The honeycomb body in question is then coated with a coating by spraying or local application.

Bei Verwendung von Pölyätherimid (PEI) erweist sich eine Wärmebehandlung von 1500C während zweier Stunden als ausreichend* Schließlich werden dann auf beiden Seiten der auf dieseA layer of thermoplastic resin dissolved in a solvent, such as N-methylpropylone, is applied by immersion. After coating with thermoplastic resin, the solvent is then evaporated during a heat treatment. When using polyetherimide (PEI), a heat treatment of 150 0 C for two hours is sufficient. Finally, the

IQ Weise präparierten Kernplatte die dünnen Außenplatten aufgebracht, welche auf ihrer Innenseite ebenfalls mit einer thermoplastischen Beschichtung versehen sind. Diese Platten werden dabei unter Druck zusammengehalten, wobei gleichzeitig eine Wärmebehandlung vorgenommen wird. Bei Verwendung eines Wabenkörpers aus Aluminium und Einsatz eines Klebemittels in Form von Pölyätherimid (PEI) erweist sich eine Wärmebehandlung von etwa 16O0C als zufriedenstellend, wobei der aufgebrachte Druck auf den halben Werten der maximalen Kompressibilität des betreffenden Wabenkörpers eingestellt ist.IQ The thin outer plates are applied to the core plate prepared in this way, and these are also provided with a thermoplastic coating on the inside. These plates are held together under pressure, and a heat treatment is carried out at the same time. When using a honeycomb body made of aluminum and an adhesive in the form of polyetherimide (PEI), a heat treatment of around 160 0 C has proven to be satisfactory, with the applied pressure set at half the value of the maximum compressibility of the honeycomb body in question.

In Abwandlung des beschriebenen Verfahrens können die beiden Wärmebehandlungen zur Verdampfung des Lösungsmittels und der Erzielung der kohäsiven Verklebung innerhalb eines einzigen Arbeitsganges durchgeführt werden, um auf diese Weise einerseits das verwendete Lösungsmittel zu verdampfen und andererseits die kohäsive Verklebung durchzuführen.In a modification of the process described, the two heat treatments for evaporating the solvent and achieving the cohesive bonding can be carried out within a single operation in order to evaporate the solvent used on the one hand and to carry out the cohesive bonding on the other.

Während bei den beschriebenen Verfahren das Aufbringen des Klebemittels innerhalb eines einzigen Arbeitsganges beschrieben worden ist, besteht im Rahmen der vorliegenden Erfindung ebenfalls die Möglichkeit, die betreffende Kernplatte zuerst mit einem Harz und in der Folge zusätzlieh mit Pölyätherimid (PEI) zu beschichten, wobei die Beschichtung mit Pölyätherimid wahlweise auf der gesamten Oberfläche des Wabenkörpers oder lokal nur an den RändernWhile the described methods describe the application of the adhesive in a single operation, the present invention also provides the possibility of first coating the core plate in question with a resin and then additionally with polyetherimide (PEI), whereby the coating with polyetherimide can be applied either to the entire surface of the honeycomb body or locally only at the edges.

Die auf diese Weise hergestellten Leichtbauplatten. entsprechen dabei weitgehend denen von Figuren 1 und 2, mit der Ausnahme/ daß vor der Aufbringung des die kohäsive Verklebung ergebenden Klebemittels züVör eine Gesämtbehandlung der Oberflache des Wabenkörpers durch Imprägnierung mit einem Harz vorgenommen worden ist, was insbesondere dann zweckmäßig erscheint, falls es sich bei der betreffenden Kernplätte um einen Wäbenkörper aus NomexiÖ nsnier handelt.The lightweight panels produced in this way largely correspond to those in Figures 1 and 2, with the exception that before applying the adhesive that results in cohesive bonding, the entire surface of the honeycomb body is treated by impregnation with a resin, which seems particularly useful if the core panel in question is a honeycomb body made of NomexÖnsnier.
