Bezeichnung: Leichte Naturstoffsandwichplatte Description: Lightweight natural material sandwich panel

BeschreibungDescription

Die Erfindung bezieht sich auf eine kostengünstige und vor allen Dingen umweltfreundliche Bauweise von sehr leichten, flächigen Bauteilen in Sandwichbauweise, bei dem die obere und untere Decklage aus Holz, der Sandwichkern aus parallel geordneten, rechtwinklig mit den Decklagen verklebten Gräserstielen zum Beispiel Stroh, besteht.The invention relates to a cost-effective and, above all, environmentally friendly construction method of very light, flat components in a sandwich construction, in which the upper and lower cover layers are made of wood, the sandwich core is made of grass stalks, for example straw, arranged in parallel and glued at right angles to the cover layers.

Die Anwendungsbereiche leichter Sandwichplatten liegen im Flugzeugbau, Fahrzeugbau aber auch im Möbel und Baubereich. Im Flugzeug- und Fahrzeugbau geht es alleine um die Gewichtsoptimierung der einzelnen Bauteile. Der Sandwich besteht dabei in der Regel aus faserverstärkten Kunststoffdecklagen und einem Kern aus Hartschaum oder Honeycombwaben. In dieser Sandwichplatte werden verschiedene Kunststoffe verarbeitet, die bei der Produktion und Verarbeitung Schadstoffe freisetzen. Wegen des Verbundes verschiedener Kunststoffe ist ein Receycling unmöglich.The areas of application for lightweight sandwich panels are in aircraft construction, vehicle construction, but also in the furniture and construction sectors. In aircraft and vehicle construction, the only thing that matters is optimizing the weight of the individual components. The sandwich usually consists of fiber-reinforced plastic cover layers and a core made of rigid foam or honeycomb. This sandwich panel contains various plastics that release harmful substances during production and processing. Due to the combination of different plastics, recycling is impossible.

Weiterhin sind Sandwichplatten aus Naturstoffen bekannt (DE-OS 31 00 094), bei denen der Kern aus Balsaholz-Klötzchen besteht. Diese Bauweise ist schwerer,von geringerer Festigkeit und teurer als die erfindungsgemäße Sandwichplatte. Die erfindungsgemäße Naturstoffsandwichplatte, mit der auch gewölbte Flachen herstellbar sind, weist außerordentlich große Biegefestigkeit, Biegesteifigkeit und Trittfestigkeit auf. Die hohe Trittfestigkeit beruht auf die jjn Faserrichtung der sich gegenseitig stützenden Stiele wirkenden Kraft und auf die, verglichen mit Kunststoffsandwichplatten gleichen Gewichts, drei bis viermal dickeren Decklagen (geringes spezifisches Gewicht von Holz).Furthermore, sandwich panels made of natural materials are known (DE-OS 31 00 094), in which the core consists of balsa wood blocks. This construction is heavier, less strong and more expensive than the sandwich panel according to the invention. The natural material sandwich panel according to the invention, with which curved surfaces can also be produced, has extraordinarily high bending strength, bending stiffness and impact resistance. The high impact resistance is based on the force acting in the direction of the fibers of the mutually supporting stems and on the cover layers, which are three to four times thicker than plastic sandwich panels of the same weight (low specific weight of wood).

Die große Biegefestigkeit und Biegesteifigkeit beruht auf der hohen spezifischen Festigkeit und dem großen spezifischen &Egr;-Modul von Holzwerkstoffen.The high bending strength and bending stiffness are based on the high specific strength and the large specific ε-modulus of wood-based materials.

Die Erfindung ist anhand einer schematischen Darstellung eines Ausführungsbeispiels in der Zeichnung verdeutlicht.The invention is illustrated by a schematic representation of an embodiment in the drawing.

Die Darstellung zeigt den Naturstoffsandwich mit den beiden Decklagen (1) und (2) aus Holzwerkstoff, die mittels Kleber (4) mit dem Sandwichkern (3) aus Gräserstielen verbunden sind.The illustration shows the natural material sandwich with the two cover layers (1) and (2) made of wood material, which are connected to the sandwich core (3) made of grass stems using adhesive (4).
