VerbundplatteComposite panel

Es sind verschiedene Arten von Verbundplatten bekannt, die als Leichtbauplatten im Immojbjjj^en- und im Fahrzeugbau eingesetzt werden. Die vorliegende Erfindung bezieht sich auf eine Verbundplatte, bestehend aus zwei Deckschichten und einer zwischen diesen angeordneten Kernschicht aus anorganischen Fasern«Various types of composite panels are known which are used as lightweight panels in real estate and vehicle construction will. The present invention relates to a composite panel consisting of two cover layers and one between this arranged core layer of inorganic fibers «

Es ist bekannt, Matten aus Glasfasern oder anderen, mineralischen Fasern beidseitig mit einer Deckschicht aus un~ oder sohwerbrennbarem Material zu verkleben. Solche Verbundplatten eignen sich für Anwendungen, wo Unbrennbarkeit der Platten verlangt wird. Sie weisen Jedoch den Nachteil auf, dass sie nur geringe Druckbelastungen von wenigen kg/m aushalten, da die nur schwach mit Kunstharz gebundenen Fasermatten, deren Fasern parallel zu den Deckschichten liegen, leicht zusammendrückbar sind«It is known to use mats made of fiberglass or other mineral materials Fibers on both sides with a cover layer made of non-combustible or non-combustible To glue material. Such composite panels are suitable for applications where incombustibility of the panels is required. she However, they have the disadvantage that they only have low pressure loads of a few kg / m, as the fiber mats, which are only weakly bound with synthetic resin and whose fibers are parallel to the Top layers are lying, are easily compressible «

Die erfindungsgemässe Verbundplatte ist dadurch gekennzeichnet, dass die Fasern senkrecht zu den Deckschichten stehen. Es hat sich gezeigt, dass solche Verbundplatten eine wesentlich höhere Druckbelastungsfähigkeit aufweisen und - sich leicht herstellen lassen. Zur Herstellung werden aus Fasermatten senkrecht zu den Fasern geschnittene Streifen, deren Breite der Dicke derThe composite panel according to the invention is characterized in that the fibers are perpendicular to the cover layers. It has it has been shown that such composite panels have a much higher Have compressive strength and - easily produce permit. For production are made of fiber mats perpendicular to the Fibers cut strips, the width of which is the thickness of the

Kernschicht der Verbundplatte entspricht, aneinandergelegt und beidseitig an den Faserenden mit den Deckschichten verklebt. Als aufzuschneidende Fasermatten kommen alle handelsüblichen Fasermatten in Frage, vorzugsweise solche, deren Fasern mittels Kunstharz miteinander verbunden sind. Zusätzlich können zwischen den Deckschichten auch noch feste Abstandhalter angeordnet sein. Als Deckschichten kommen vor allem Metalle, z.B. Aluminiumbleche, oder glasfaserverstärkte Kunststoffplatten, z.B. mit einem Thermoplasten oder mit einem härtbaren Kunstharz imprägnierte Glasfasermatten, in Frage. Bei Verwendung von Deckschichten aus Kunstharzen wird kein Klebstoff zum Verbinden von Kernschicht und Deckschichten benötigt; beim Verpressen unter Erhitzung erweicht das Kunst-; harz der Deckschichten, klebt die Enden der Fasern fest und härtet im Falle eines härtbaren Kunstharzes aus* Die Deckschichten können auch ihrerseits bereits Verbundschichten verschiedener Materialien sein, die als vorgefertigter Verbund" mit der Kernschicht verpresst, oder deren einzelne Schichten gleichzeitig mit dem Verpressen mit der Kernschicht miteinander verbunden werden. Als Verbund-Deckschichten sind besonders solche vorteilhaft, die gegen die Kernschicht aus Kunststoff, und aussen aus Aluminium bestehen. Durch die aussere Aluminiumschicht erhält die Verbundplatte eine hohe Witterungs-. beständigkeit» Zum direkten Verbinden der Kernschicht mit metallischen Deckschichten wird ein Klebstoff benötigt.Corresponds to the core layer of the composite panel, placed one against the other and glued to the outer layers on both sides at the fiber ends. All commercially available fiber mats can be used as fiber mats to be cut open, preferably those whose Fibers are connected to one another by means of synthetic resin. In addition, fixed layers can also be used between the top layers Be arranged spacers. The top layers are mainly metals, e.g. aluminum sheets or glass fiber reinforced Plastic sheets, e.g. with a thermoplastic or with a curable synthetic resin impregnated fiberglass mats, in question. When using top layers made of synthetic resins, no Adhesive for joining the core and top layers needed; when pressed under heating, the artificial material softens; Resin of the outer layers, sticks the ends of the fibers and hardens in the case of a curable synthetic resin * The top layers can for their part already be composite layers of different materials, which are used as a prefabricated composite " pressed with the core layer, or their individual layers simultaneously with the pressing with the core layer with one another get connected. As composite top layers are special those which are made of plastic against the core layer and which are made of aluminum on the outside are advantageous. The outer aluminum layer gives the composite panel a high level of weathering. resistance »An adhesive is required to connect the core layer directly to the metallic cover layers.

Die anorganischen Pasern können Glasfasern oder Fasern aus irgendwelchen anorganischen Stoffen sein.The inorganic fibers can be glass fibers or fibers any inorganic substances.

Beispiel 1example 1

Eine handelsübliche, mit Phenolharz gebundene, 40 mm starke Glasfaser-Isoliermatte wird in 50 mm breite Streifen geschnitten. Der Schnitt wird senkrecht zu den Fasern gelegt. Die Streifen werden um 90 gedreht und eng aneinandergelegt, so dass eine Platte mit stehenden Pasern entsteht. Die Platte wird beidseitig mit einer mit Diallylphthalat-Harz getränkten Glasfasermatte von 1200 g/m mit 50 % Glasgehalt belegt. Dieser "Sandwich" wird in eine auf l40°C geheizte Plattenpresse eingeführt und während 10 min mit 2 kg/cm verpresst. Das Diallylphthalat-Harz erweicht vorerst, klebt die Enden .-.-,< der Glasfasern der Matte-Streifen fest und härtet dann aus. Die fertige Verbund-Platte hält Drucke bis zu 20 t/m aus.A commercially available, phenolic resin-bonded, 40 mm thick glass fiber insulating mat is cut into 50 mm wide strips. The cut is made perpendicular to the fibers. The strips are turned by 90 and placed close together, so that a plate with standing lines is created. The plate is covered on both sides with a glass fiber mat impregnated with diallyl phthalate resin of 1200 g / m 2 with a glass content of 50%. This "sandwich" is introduced into a plate press heated to 140 ° C. and pressed at 2 kg / cm 2 for 10 minutes. The diallyl phthalate resin first softens, sticks the ends.-.-, <of the glass fibers of the mat strips and then hardens. The finished composite panel can withstand pressures of up to 20 t / m.
