Description
Die vorliegende Erfindung betrifft einen Formkörper ge mäß dem Oberbegriff des Anspruchs 1.The present invention relates to a shaped body according to the preamble of claim 1.
Derartige Formkörper sind an sich bekannt. Man nutzt da bei in erster Linie ihre anisotropen Eigenschaften bei gekreuzten Faserorientierungswinkeln, um die Gesamtfestig keit eines mehrlagigen Verbundes und eine Verzugsfreiheit durch Ausgleich der Spannungen zu erreichen. So haben sich zum Beispiel derartige Formkörper aus Glas faserkunststoff seit Jahren bewährt. Hierbei sind kunst harzimprägnierte Glasfasermatten und -gewebe lagenweise aufeinandergelegt und verklebt beziehungsweise verpreßt. Auf die gleiche Weise sind Holzfurniere mittels Verlei mung bei sich kreuzender Faserrichtung zu Sperrholz ver bunden.Shaped bodies of this type are known per se. You use there at primarily their anisotropic properties crossed fiber orientation angles to keep the overall strength multi-layer composite and freedom from distortion by balancing the tensions. For example, such shaped bodies made of glass fiber plastic has proven itself for years. Here are art resin-impregnated glass fiber mats and fabrics in layers placed on top of each other and glued or pressed together. In the same way, wood veneers are leased with crossing fiber direction to plywood bound.
Beide Formkörperarten haben jedoch gegen über monolithischen Gebilden erhebliche Nachteile. So hat zum Beispiel ein Formkörper aus Glasfaserkunststoff den Nachteil des relativ hohen Gewichts bei größerer Laminats dicke und entsprechender Beulsteifigkeit, während zum Beispiel bei Verwendung von Carbonfasern die Beulsteifig keit ausreichend, aber der Faserpreis zu hoch ist. Ein Formkörper aus Holzfurnieren dagegen zu Sperrholz ver preßt läßt eine ausreichende Zug-, Druck-, Biege- und Scherfestigkeit sowie Kerbschlagszähigkeit vermissen. Formkörper der beiden vorgenannten Arten lassen sich so mit bei höheren Festigkeitsanforderungen nicht einsetzen.However, both types of moldings have against significant disadvantages over monolithic structures. So had For example, a molded body made of fiberglass Disadvantage of the relatively high weight with larger laminates thick and corresponding buckling stiffness, while for Example when using carbon fibers the buckling stiff sufficient, but the fiber price is too high. A Molded bodies made of wood veneer, on the other hand, ver to plywood presses a sufficient tensile, compressive, bending and Missing shear strength and impact strength. Shaped bodies of the two types mentioned above can be so do not use with higher strength requirements.
Aus der EP 01 42 906 ist ein gattungsgemäßer Formkörper bekannt, bei dem der Holzwerkstoff aus einem Furnier be steht und bei dem die Laminatschicht durch ein Kunstharz mit dem Holzwerkstoff verbunden ist.EP 01 42 906 is a generic molded article known in which the wood-based material be from a veneer stands and in which the laminate layer by a synthetic resin is connected to the wood material.
Dabei wird das Laminat beispielsweise in Form eines soge nannten Prepregs aufgebracht, wobei das Fasergewebe mit Kunstharz vorimprägniert ist. Nachteilig bei dem bekannten Formkörper ist, daß aufgrund der Beschaffenheit und der daraus resultierenden ungenü genden Verbindung der Laminatschicht mit dem Holzwerk stoff keine optimale Belastungsfähigkeit erzielbar ist.The laminate is for example in the form of a so-called called prepregs applied, the fiber fabric is pre-impregnated with synthetic resin. A disadvantage of the known shaped body is that the nature and the resulting inaccurate connecting the laminate layer with the woodwork optimal load capacity cannot be achieved.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Formkörperder gattungsgemäßen Art so zu gestalten, daß die Belastungsfähigkeit insgesamt verbessert und die Herstellungskosten gesenkt werden.The present invention is based on the object to design a shaped body of the generic type in such a way that the resilience improves overall and the Manufacturing costs can be reduced.
Diese Aufgabe wird erfindungsgemäß durch die im kennzeich nenden Teil des Anspruchs 1 genannten Merkmale gelöst. This object is achieved by the in the characterizing solved part of claim 1 mentioned features.
Diese Maßnahmen bringen zunächst eine bessere Verbindung der Faserschicht mit dem Holzwerkstoff, da sich die para llel zueinander verlaufenden und lückenlos nebeneinander liegenden Fasern, die auch als Filamente bezeichnet werden, praktisch eine Vollfläche bilden, in der keine Zwischen räume, wie sie beispielsweise bei Geweben durch Fadenver kreuzungen vorliegen, vorhanden sind.These measures initially bring a better connection the fiber layer with the wood material, since the para ll to each other and seamlessly next to each other lying fibers, which are also called filaments, practically form a full surface in which there are no intermediate spaces spaces, such as those used in fabrics by thread ver there are crossings.
Neben der erheblich verbesserten mechanischen Belastungs fähigkeit des Formkörpers ist auch eine erhebliche Ver besserung der Feuerbeständigkeit hervorzuheben, da das lückenlose Nebeneinanderliegen der einzelnen Fasern den auftreffenden Flammen keine Möglichkeit läßt, auf den darunter liegenden Holzwerkstoff durchzuschlagen.In addition to the significantly improved mechanical stress ability of the molded body is also a considerable Ver improvement of fire resistance, since the seamless juxtaposition of the individual fibers flames hitting no possibility on the to break through underlying wood material.
Durch die Verwendung von unbrennbarem Phenolharz ist der Formkörper sowohl feuer- als auch witterungsbeständig, wobei die Sichtseite mit einer Dekorplatte versehen sein kann.Through the use of incombustible phenolic resin, the Molded bodies both fire and weather resistant, the visible side being provided with a decorative panel can.
Durch die Erfindung wird der Anteil der Fasern am Volumen der Laminatschicht gegenüber dem Stand der Technik we sentlich erhöht, so daß entweder die Belastungsfähigkeit steigt oder bei bleibender Belastungsfähigkeit das Vo lumen und somit die aufzubringende Harzmenge reduziert werden kann. Dies bedeutet eine erhebliche kostenmindernde Material und Gewichtseinsparung.Through the invention, the proportion of fibers in the volume the laminate layer compared to the prior art considerably increased, so that either the resilience increases or the Vo lumen and thus the amount of resin to be applied is reduced can be. This means a significant cost reducing material and weight saving.
Eine besonders vorteilhafte, da preiswerte Herstellung eines Formkörpers ist dann gegeben, wenn der Holzwerk stoff aus einer Spanplatte besteht, die dann als Platten werkstoff für die Bau- und Möbelindustrie eingesetzt wer den kann. Weitere Einsatzmöglichkeiten bieten sich an im Waggon und Fahrzeugbau, Behälter- und Containerbau; als Scha lungsplatten im Bauwesen; Formenbau; Boots- und Schiff bau; Transport- und Lagerbehälter für schwere und scharf kantige Transportgüter; Brückenbeläge; sowie aufgrund der absoluten Wetterbeständigkeit als Bauelemente im Außen bereich und als Fassaden-Großelemente.A particularly advantageous, because inexpensive manufacture a shaped body is given when the woodwork fabric consists of a particle board, which is then used as panels material used in the construction and furniture industries that can. Other possible uses are in the wagon and vehicle construction, container and container construction; as Scha slabs in building; Mold making; Boat and ship construction; Transport and storage containers for heavy and sharp angular transport goods; Bridge coverings; as well as due to the absolute weather resistance as building elements on the outside area and as large facade elements.
Der erfindungsgemäße Formkörper wird aus den beiden Hauptkomponenten Holzfurnier A und Faserkunststoff B vorzugsweise in sich jeweils kreuzender Faserorientierung (0° und 90°) gefertigt, wobei ein wichtiger Erfindungs gedanke ist, daß eine aufwendige Beleimung der Furnier lagen (A1 und A2) entfallen kann. Dieses wird erreicht durch eine lmprägnierung der parallel zueinander verlau fenden Fasern, die auch als unidirektionale Fasergelege (B1 und B2) bezeichnet werden können, mit einer Mengen- Überdosierung des Imprägnierharzes auf der Basis von Epoxid, Polyester, Phenol, Melamin, Harnstoff, Silicon oder dergleichen. Diese unidirektionalen Fasergelege können vorgefertigt sein oder örtlich durch Zulauf von Faserrovings durch Direktabzug von einem Spulenbaum auf den Holzwerkstoff aufgelegt werden.The molded body according to the invention is made from the two main components, wood veneer A and fiber plastic B, preferably in a crossing fiber orientation (0 ° and 90 °), an important idea of the invention being that there was no need for expensive gluing of the veneer (A 1 and A 2 ) can. This is achieved by impregnating the fibers running parallel to one another, which can also be referred to as unidirectional fiber fabrics (B 1 and B 2 ), by overdosing the impregnating resin on the basis of epoxy, polyester, phenol, melamine, urea, Silicone or the like. These unidirectional fiber fabrics can be prefabricated or placed locally on the wood material by feeding in fiber rovings by pulling them off directly from a spool tree.
Je nach den Einsatzanforderungen sind beliebige Zuord nungen der Einzellagen möglich. Es sind auch andere Faser kreuzungswinkel möglich, um zum Beispiel einen erfindungs gemäßen Formkörper mit quasi-isotropen Eigenschaften zu erstellen, der in allen Beanspruchungsebenen gleiche Wi derstandmomente und gleiche mechanische Festigkeiten hat.Any assignment is possible depending on the application requirements Individual layers are possible. There are other fibers too crossing angle possible, for example to create an invention according to shaped bodies with quasi-isotropic properties create the same Wi in all stress levels which has moments of torque and the same mechanical strength.
Ein weiterer Gedanke der Erfindung ist die Verwendung von unidirektionalen Carbonfasergelegen mit hohem Elastizi tätsmodul und zugleich sehr hoher spezifischer Zugfestig keit. lm Einzelfall kann es auch sinnvoll sein, einen solchen Verbund bei Verwendung des Formkörpers zu er stellen, der für Abschirmungen gegen Strahlung oder ex trem leichte und hoch belastbare Formkörper vorgesehen.Another idea of the invention is the use of unidirectional carbon fiber fabric with high elasticity module and at the same time very high specific tensile strength speed. In individual cases it can also make sense to have one such composite when using the molded body to he ask for shielding against radiation or ex Extremely light and heavy-duty molded body provided.
Für viele Bereiche ist der Formkörper mit einem Dekor, aufgedruckt oder als Einzelschicht, versehen.For many areas, the molded body has a decor, printed or as a single layer.
Wie bereits erwähnt, ist eine preiswerte Möglichkeit da durch gegeben, daß eine Spanplatte auf mindestens einer Fläche mit imprägnierten unidirektionalen Fasern be schichtet ist. Falls beide Flächen auf diese Weise be schichtet sind, ergibt sich dadurch ein Sandwicheffekt, wobei die Holzspanplatte die statisch neutrale Zone und die unidirektionalen Faserstofflagen die Ober- und Unter gurte analog zu einem TT-Träger bilden.As already mentioned, there is an inexpensive option given that a chipboard on at least one Surface with impregnated unidirectional fibers is layered. If both surfaces are in this way layered, this results in a sandwich effect, the chipboard is the static neutral zone and the unidirectional fiber layers the top and bottom Form belts analogous to a TT carrier.
