Description

SandwichplatteSandwich panel

Die Erfindung bezieht sich auf eine Sandwichplatte, die aus mehreren, miteinander verbundenen Schichten besteht.The invention relates to a sandwich panel consisting of several interconnected layers.

Sandwichplatten weisen in der Regel eine hohe Biegesteifigkeit und Druckfestigkeit bei gleichzeitig geringem Gewicht auf. Bei einfachen Anwendungen werden jedoch geringere Anforderungen an die Eigenschaften der Sandwichplatte gestellt, so daß für diese Anwendungen solche Sandwichplatte prinzipiell zu aufwendig sind. Entsprechend dem in Relation zu den Anforderungen zu aufwendigen Aufbau fallen infolgedessen auch erhöhte Kosten an.Sandwich panels generally have high flexural rigidity and compressive strength while being lightweight. However, for simple applications, the requirements for the properties of the sandwich panel are lower, so that such sandwich panels are in principle too complex for these applications. As the structure is too complex in relation to the requirements, the costs are also increased.

Aufgabe der vorliegenden Erfindung ist es, eine Sandwichplatte zu schaffen, die für einfachere Anwendungen eine ausreichende Stabilität aufweist und dabei kostengünstig herstellbar ist.The object of the present invention is to create a sandwich panel which has sufficient stability for simpler applications and can be produced cost-effectively.

5 Zur Lösung dieser Aufgabe wird vorgeschlagen, daß die Sandwichplatte einen thermoplastischen Stützkern sowie zumindest auf einer Seite dieses Stützkerns eine über eine Klebeschicht damit verbundene, faserverstärkte Deckschicht aufweist.
Dadurch ist ein leichtes, steifes Sandwich-Verbündteil geschaffen, das für viele Anwendungen ausreichende Eigenschaften hat, beispielsweise für den Einsatz als Abtrennwand. Durch die5 To achieve this object, it is proposed that the sandwich panel has a thermoplastic support core and, on at least one side of this support core, a fibre-reinforced cover layer connected to it by an adhesive layer.
This creates a lightweight, rigid sandwich composite part that has sufficient properties for many applications, for example for use as a partition wall.

faserverstärkte Deckschicht sind die darunterliegenden Materialien vor äußeren Umwelteinflüssen, wie insbesondere UV-Strahlung, Feuchtigkeit, Chemikalien und dergleichen geschützt, so daß ein Einsatz auch unter entsprechenden Umgebungsbedingungen möglich ist. 5The fiber-reinforced top layer protects the materials underneath from external environmental influences, such as UV radiation, moisture, chemicals and the like, so that use is also possible under corresponding environmental conditions. 5

Bei Minimalanforderungen genügt eine auf einer Seite des Stützkerns aufgeklebte Deckschicht, während bei etwas erhöhten Festigkeitsanforderungen oder aber bei Beaufschlagung der Sandwichplatte mit äußeren Einflüssen auf beiden Seiten, eine beidseitig auf dem Stützkern jeweils mittels einer Klebeschicht damit verbundene, faserverstärkte Deckschicht vorgesehen ist.For minimum requirements, a cover layer glued to one side of the support core is sufficient, while for slightly higher strength requirements or when the sandwich panel is exposed to external influences on both sides, a fiber-reinforced cover layer is provided on both sides of the support core, each connected to it by means of an adhesive layer.

Für eine noch weiter erhöhte Steifigkeit der Sandwichplatte kann zumindest eine faserverstärkte Deckschicht mittelbar über eine Zwischenschicht mit dem Stützkern verbunden sein, wobei diese 5 Deckschicht durch eine Klebeschicht mit der Zwischenschicht verbunden ist. Dabei besteht auch die Möglichkeit, zur Festigkeitserhöhung die Zwischenschicht mit einer Faserarmierung zu versehen.
Weiterhin kann die Zwischenschicht aus einer thermisch verdichteten Vliesschicht aus thermoplastischem Material bestehen. Durch Verwendung einer im Ausgangszustand als Vliesschicht vorliegenden Zwischenschicht werden gegebenenfalls von der Zwischenschicht ausgehende, innere Spannungen und damit unerwünschte Verformungen der Sandwichplatte vermieden. Beim Verbinden der Vliesschicht mit dem Stützkern wird die Vliesschicht praktisch vollständig aufgeschmolzen und zu einer homogenen Schicht verdichtet. Bevorzugt erfolgt dabei die Verbindung mit dem Stützkern durch eine stoffliche Schmelzverbindung.To further increase the rigidity of the sandwich panel, at least one fiber-reinforced cover layer can be indirectly connected to the support core via an intermediate layer, with this cover layer being connected to the intermediate layer by an adhesive layer. It is also possible to provide the intermediate layer with fiber reinforcement to increase strength.
The intermediate layer can also consist of a thermally compressed fleece layer made of thermoplastic material. By using an intermediate layer that is initially present as a fleece layer, any internal stresses emanating from the intermediate layer and thus undesirable deformations of the sandwich panel are avoided. When the fleece layer is connected to the support core, the fleece layer is almost completely melted and compressed into a homogeneous layer. The connection to the support core is preferably made using a material melt connection.

Für ein niedriges Gewicht der Sandwichplatte ist es vorteilhaft, wenn der Stützkern durch eine Wabenschicht gebildet ist.To keep the weight of the sandwich panel low, it is advantageous if the supporting core is formed by a honeycomb layer.

Zusätzliche Ausgestaltung der Erfindung sind in den weiteren Unteransprüchen aufgeführt.Additional embodiments of the invention are set out in the further subclaims.

Nachstehend ist die Erfindung mit ihren wesentlichen Einzelheiten anhand der Zeichnungen noch näher erläutert.The invention and its essential details are explained in more detail below with reference to the drawings.

Es zeigt etwas schematisiert:It shows something schematic:

Fig. 1 eine dreischichtige Sandwichplatte und eine
Fig. 2 fünfschichtige Sandwichplatte.Fig. 1 a three-layer sandwich panel and a
Fig. 2 five-layer sandwich panel.

Fig. 1 zeigt eine dreischichtige Sandwichplatte 1 , die einen Stützkern 2 sowie beidseitig mit diesem über jeweils eine Klebeschicht 3 verbundene, faserverstärkte Deckschichten 4 und 5 aufweist. Diese Sandwichplatte 1 weist bei geringem Gewicht eine ausreichende Festigkeit auf, so daß sie für Anwendungsbereiche mit keinen all zu hohen Festigkeitsanforderungen gut einsetzbar ist. Eine solche Sandwichplatte läßt sich auch auf einfache Weise herstellen, indem der Stützkern 2, die Klebeschichten 3 sowie die Deckschichten 4 und 5 bahnförmig zusammengeführt und unter Wärmeeinfluß miteinander verbunden werden. Es sind dadurch praktisch "Endlos"-Sandwichplatten 1 herstellbar.Fig. 1 shows a three-layer sandwich panel 1, which has a support core 2 and fiber-reinforced cover layers 4 and 5 connected to it on both sides by an adhesive layer 3. This sandwich panel 1 has sufficient strength despite its low weight, so that it can be used for applications with not too high strength requirements. Such a sandwich panel can also be produced in a simple manner by bringing the support core 2, the adhesive layers 3 and the cover layers 4 and 5 together in a web-like manner and bonding them together under the influence of heat. This makes it possible to produce practically "endless" sandwich panels 1.

Für die faserarmierten Deckschichten 4 und 5 können auch solche verwendet werden, bei denen die Faserarmierung vollständig in die Deckschicht eingebettet ist. Solche Deckschichten können durch eine mittig liegende Gewebearmierschicht und beidseitig damit verbundene thermoplastische Schichten gebildet sein. Dadurch ist auch eine glatte Außenseite vorhanden, die bedarfsweise lackiert werden kann.For the fiber-reinforced cover layers 4 and 5, it is also possible to use those in which the fiber reinforcement is completely embedded in the cover layer. Such cover layers can be formed by a fabric reinforcement layer in the middle and thermoplastic layers connected to it on both sides. This also creates a smooth outer side that can be painted if necessary.

Andererseits besteht auch die Möglichkeit, eine strukturierte Deckschicht 4 und/oder 5 zu verwenden, wobei die Struktur durch die Faserverstärkung hervorgerufen werden kann und wobei über die Textur das Erscheinungsbild der Oberfläche entsprechend gestaltet werden kann. Weiterhin besteht die Möglichkeit, eingefärbte Folien als Deckschicht zu verwenden.On the other hand, it is also possible to use a structured cover layer 4 and/or 5, whereby the structure can be caused by the fiber reinforcement and whereby the appearance of the surface can be designed accordingly via the texture. It is also possible to use colored films as a cover layer.

Figur 2 zeigt eine Sandwichplatte 1a, bei der die äußeren Deckschichten 4 und 5 mittelbar jeweils über eine Zwischenschicht 6 mit dem Stützkern 2 verbunden sind. Im vorliegenden Ausführungsbeispiel sind die Zwischenschichten 6 durch eine stoffliche Schmelz-Figure 2 shows a sandwich panel 1a in which the outer cover layers 4 and 5 are each indirectly connected to the support core 2 via an intermediate layer 6. In the present embodiment, the intermediate layers 6 are connected by a material melt

Verbindung mit dem als Wabenschicht 7 ausgebildeten Stützkern 2 verbunden. Die Zwischenschichten 6 und der Stützkern 2 bestehen dazu aus thermoplastischem Material. Außenseitig auf den Zwischenschichten 6 befinden sich die Klebeschichten 3 zum Verbinden mit den äußeren Deckschichten 4 und 5. Die Zwischenschichten 6 ergeben insgesamt eine höhere Steifigkeit der Sandwichplatte. Bedarfsweise können die Zwischenschichten faserverstärkt sein.Connection with the support core 2 designed as a honeycomb layer 7. The intermediate layers 6 and the support core 2 consist of thermoplastic material. On the outside of the intermediate layers 6 there are adhesive layers 3 for connecting to the outer cover layers 4 and 5. The intermediate layers 6 result in a higher overall rigidity of the sandwich panel. If necessary, the intermediate layers can be fiber-reinforced.

Auch diese Sandwichplatte 1a kann aus mehreren bahnförmig zugeführten Folien quasi endlos hergestellt werden. Die Deckschichten 4 und 5 können aus einer thermoplastischen Folie mit einer Dicke von etwa 0,5 bis etwa 0,7 mm ausgebildet sein, während die Zwischenschichten eine Dicke von wenigstens 0,5 mm aufweisen und je nach Festigkeitsanforderungen auch wesentlich dicker ausgebildet sein können.
15This sandwich panel 1a can also be produced in a virtually endless manner from several films fed in web form. The cover layers 4 and 5 can be made from a thermoplastic film with a thickness of about 0.5 to about 0.7 mm, while the intermediate layers have a thickness of at least 0.5 mm and can also be made significantly thicker depending on the strength requirements.
