Abstract
Description
Sandwichmaterialien zeichnen sich dadurch aus, dass in einer Mittelschicht, die üblicherweise aus Polyurethanschaum oder einer Wabenstruktur, beispielsweise aus Papier- oder Kunststoffwaben besteht, beidseitig Deckschichten aus beispielsweise glasfaserverstärktem Kunststoff, Aluminiumblech oder anderen Materialien aufgebracht werden.sandwich materials are characterized by the fact that in a middle class, usually polyurethane foam or a honeycomb structure, for example Paper or plastic honeycomb consists, on both sides of cover layers for example, glass fiber reinforced Applied plastic, aluminum sheet or other materials become.
Die Herstellung der Deckschichten geschieht üblicherweise in verschiedenen Arbeitsschritten. Beispielsweise werden die Deckschichten aus glasfaserverstärktem Kunststoff in einem separaten Arbeitsschritt gefertigt und kommen dann zum Einsatz als Deckschicht bei der Herstellung von Sandwichmaterial.The Production of the outer layers is usually done in different Steps. For example, the cover layers of glass fiber reinforced plastic manufactured in a separate step and then come to Use as topcoat in the production of sandwich material.
Kommt Polyurethanschaum zum Einsatz, so wirkt sich dies positiv auf die Druckfestigkeit aus. Hierunter leidet die Biegesteifheit.comes Polyurethane foam used, so it has a positive effect on the Pressure resistance. This is where bending stiffness suffers.
Beim Einsatz von Wabenmaterial als Mittelschicht wirkt sich dies positiv auf die Biegesteifheit des Materials aus. Hierbei kommt es zu Nachteilen bei der Druckfestigkeit. Die Erfindung ist für ein Ausführungsbeispiel in der Zeichnung schematisch im Schnitt dargestellt.At the Using honeycomb as a middle layer has a positive effect on the bending stiffness of the material. Here it comes to disadvantages the compressive strength. The invention is for an embodiment in the drawing shown schematically in section.
