Sandwichartig
aufgebaute Verbundmaterialien werden vielfach als Leichtbaukomponenten
eingesetzt. Aus der
Sandwich-Verbundmaterialien
in Leichtbauweise mit Gesamtdicken kleiner 2 mm lassen sich mit den
obigen Verfahren, beispielweise mit dem aus der
Der Erfindung liegt somit die Aufgabe zugrunde, ein Verfahren zur Verfügung zu stellen, mit welchem sehr dünne, leichte und biegesteife Sandwich-Verbundmaterialien mit einer Kernschicht aus einem Kunststoff-Schaum kostengünstig herstellbar sind.Of the Invention is therefore the object of a method available with which very thin, lightweight and rigid sandwich composite materials can be produced inexpensively with a core layer of a plastic foam.
Gelöst wird die gestellte Aufgabe erfindungsgemäß dadurch, dass die Kernschicht durch mechanisches Schneiden eines Kunststoff-Hartschaumblockes mit einer glatten, ungezackten und ungewellten Schneide bzw. Klinge hergestellt wird und nachfolgend zumindest eine zugsteife Schicht aus einer Folie durch ein Klebeverfahren aufgebracht wird. Bevorzugt werden Schäume mit einer durchschnittlichen Zellgröße kleiner als 0,4 mm verwendet.Is solved the task according to the invention in that the core layer by mechanical cutting of a plastic rigid foam block with a smooth, ragged and uneven edge or blade is produced and subsequently at least one zugsteife layer is applied from a film by an adhesive method. Prefers become foams used with an average cell size smaller than 0.4 mm.
Die Erfindung gestattet die kostengünstige Herstellung von Verbundmaterialien unter Verwendung besonders feinzelliger Hartschaumkernschichten mit hoher Schubsteifigkeit in Kombination mit sehr dünnen leichten zugsteifen Schichten. Erfindungsgemäß hergestellte Verbundmaterialien weisen eine hohe Steifigkeit bei einem geringen Gewicht auf und können sehr dünn ausgeführt werden. Die Erfindung bietet den besonderen Vorteil, dass auch sehr feinzeilige Kunststoff-Hartschäume mit sehr geringen Porengrößen für einen Sandwichverbund erzeugt und als Kernschicht verwendet werden können, welche eine gute Homogenität und damit eine hohe Schubsteifigkeit auch bei geringen Stärken des Sandwichverbundes aufweisen. Der erfindungsgemäß hergestellte Gesamtverbund ist daher biegesteif und gleichzeitig leicht.The Invention allows cost-effective production of composite materials using particularly fine cellular hard foam core layers with high shear stiffness in combination with very thin lightweight tensile layers. Composite materials produced according to the invention have a high stiffness at a low weight and can very thin accomplished become. The invention offers the particular advantage that also very Fine-line plastic rigid foams with very small pore sizes for one Sandwich composite can be produced and used as a core layer, which a good homogeneity and thus a high shear stiffness even at low strengths of sandwich composite exhibit. The inventively produced Overall composite is therefore rigid and light at the same time.
Besonders dünne Kernschichten lassen sich dadurch herstellen, dass beim mechanischen Schneiden des Kunststoff-Hartschaumblockes der Winkel zwischen Schnittkante und Bewegungsrichtung der Schneide bzw. der Klinge maximal 80° beträgt. Alternativ dazu kann die Schneide bzw. Klinge während des Schneidens in Schnittkantenrichtung oszillierend hin- und herbewegt werden.Especially thin core layers can be produced by mechanical cutting of the plastic foam block the angle between the cutting edge and the direction of movement of the blade or the blade is 80 ° maximum. alternative For this purpose, the blade or blade during cutting in the cutting edge direction oscillating be moved back and forth.
Bei einer bevorzugten Ausführungsform der Erfindung wird beidseitig der Kernschicht eine zugsteife Schicht aufgebracht. Als zugsteife Schicht eignet sich Aluminiumfolie, welche aufgrund ihrer geringen Stärke und ihrer Zugsteifigkeit zur Herstellung sehr dünner Verbundmaterialien besonders gut einsetzbar ist. Ebenso verwendbar sind andere metallische Folienwerkstoffe, beispielsweise Stahlfolien, oder Kunststofffolien sowie Vliese aus Fasern.at a preferred embodiment The invention provides a tension-resistant layer on both sides of the core layer applied. As zugsteife layer is aluminum foil, which because of their low strength and their tensile stiffness for producing very thin composite materials especially is well usable. Likewise usable are other metallic film materials, For example, steel foils, or plastic films and nonwovens Fibers.
Gemäß der Erfindung kann ferner zumindest eine zusätzliche Schicht eingebracht oder aufgebracht werden.According to the invention can also at least one additional Layer introduced or applied.
Als außen aufgebrachte Schichten kommen beispielsweise gummiartige weiche Werkstoffe in Frage, welche der Außenseite des Verbundmaterials einen Softtoucheffekt verleihen, oder Schichten aus Lack oder einem lackähnliche Eigenschaften aufweisenden Material.When Outside Applied layers come, for example, rubbery soft Materials in question, which the outside of the composite material Soft-touch effect, or layers of paint or a paint-like Properties having material.
Eine besonders haltbare Verbindung der Kernschicht mit der zugsteifen Schicht lässt sich durch Verkleben mittels einer Heißklebefolie erzielen. In diesem Zusammenhang ist es ferner vorteilhaft, wenn beheizte Walzen zur Verklebung verwendet werden.A particularly durable connection of the core layer with the zugsteifen Layer leaves to achieve by gluing using a hot-melt adhesive film. In this In connection, it is also advantageous if heated rolls for Bonding can be used.
Gemäß einer bevorzugten Ausführungsform der Erfindung wird das Verbundmaterial in einem nachträglichen Verfahrensschritt geformt, um es dem vorgesehenen Anwendungszweck anzupassen. Zum Formen des erfindungsgemäßen Verbundmaterials eignen sich beispielsweise Tiefziehen oder Prägen. Das geformte oder auch ungeformte Verbundmaterial kann ferner nachträglich im Spritzgussverfahren mit Kunststoff hinterspritzt werden oder es können auf das Verbundmaterial im Spritzgussverfahren Funktionselemente aufgebracht werden.According to a preferred embodiment of the invention, the composite material is formed in a subsequent process step to adapt it to the intended application. For example, thermoforming or embossing are suitable for molding the composite material according to the invention. The molded or unshaped composite material can also be subsequently injected by injection molding with plastic or it can be be applied to the composite material by injection molding functional elements.
Die Erfindung betrifft ferner ein gemäß dem erfindungsgemäßen Verfahren hergestelltes Verbundmaterial.The The invention further relates to a method according to the invention produced composite material.
Auf das Gewicht des Verbundmaterials wirkt es sich besonders günstig aus, wenn die aus Kunststoff-Hartschaum bestehende Kernschicht eine Dichte kleiner als 250 kg/m3, insbesondere kleiner als 150 kg/m3, aufweist. Zur Herstellung besonders dünner und leichter Kernschichten eignen sich Kunststoff-Hartschäume auf der Basis von Polystyrol oder auf der Basis von Polypropylen.On the weight of the composite material, it has a particularly favorable if the core layer consisting of rigid plastic foam has a density of less than 250 kg / m 3 , in particular less than 150 kg / m 3 . Plastic rigid foams based on polystyrene or based on polypropylene are suitable for producing particularly thin and lightweight core layers.
Ein erfindungsgemäßes Verbundmaterial kann eine Kernschichtdicke kleiner als 2 mm, vorzugsweise sogar kleiner als 0,5 mm, und insgesamt eine Dicke kleiner als 3 mm, bei besonders dünnen Kernschichten sogar kleiner als 0,7 mm aufweisen. Dabei ist es von Vorteil, wenn die Dicke jeder zugsteifen Schicht gemeinsam mit ihrer Klebeschicht höchstens 50 μm beträgt.One Composite material according to the invention a core layer thickness less than 2 mm, preferably even smaller than 0.5 mm, and a total thickness less than 3 mm, especially thin core layers even less than 0.7 mm.
