Abstract

A composite component for use as an interior wall lining, esp. for aircraft comprises a cork core with faces of a higher modulus material. The cork is saturated in a binder which is fire resistant, prevents heat build up and does not produce toxic gas in a fire, therefore acting as a self-extinguishing agent. The panel comprises a core (1) of cork saturated in a fire resistant binder with low smoke and toxic gas generation. Higher modulus faces (4, 5) are bonded (2, 3) to each side of the core (1) with adhesive e.g. phenol or polyurethane based. The faces (4, 5) may be fibre reinforced plastic e.g. glass reinforced phenol formaldehyde or metal plate e.g. steel, aluminium. USE/ADVANTAGE - The composite panel can be used as a wall lining or partition within passenger aircraft and is fire resistant without increasing cost.

Description

Die Erfindung betrifft ein flächenhaftes Bauelement in Verbund­ bauweise, mit einem Kern aus Korkwerkstoff sowie auf dessen Außenflächen aufgebrachten Deckschichten.The invention relates to a flat component in composite construction, with a core made of cork material and on its outer surfaces applied top layers.

Bauelemente dieser Art werden unter anderem für die Innenausstat­ tung von Verkehrsflugzeugen verwendet. Sie dienen unter anderem als Verkleidungen für Fracht- und Passagierräume und als Trennwände. Der Kern dieser in Verbundbauweise herstellbaren Bauelemente kann aus wabenförmig aufgebauten Platten oder aus Korkwerkstoffen bestehen und wird entsprechend der gewünschten äußeren Form des betreffenden Bauelementes zugeschnitten und auf der Unter- und Oberseite mit Deckschichten, entweder aus faserverstärkten Kunststoff oder Metallblech, versehen. Kerne aus Korkwerkstoffen haben dabei den Vorteil einer homogenen Außenkon­ tur und erfordern für den Randbereich keine zusätzlichen Füllmas­ sen.Components of this type are used, among other things, for interior decoration used by commercial aircraft. They serve among other things as cladding for cargo and passenger compartments and as Partitions. The core of this can be produced in composite construction Components can be made from honeycomb-shaped panels or from Cork materials exist and are made according to the desired tailored outer shape of the component in question and on the bottom and top with top layers, either from fiber-reinforced plastic or sheet metal. Cores out Cork materials have the advantage of a homogeneous outer cone  structure and do not require any additional filling measures for the edge area sen.

Aufgabe der Erfindung ist es, ein Bauelement der eingangs genann­ ten Art so auszubilden, daß es ohne Zusatzaufwand feuerbeständig wird.The object of the invention is to provide a component of the type mentioned ten kind so that it is fire-resistant without additional effort becomes.

Die Erfindung löst diese Aufgabe durch ein Bauelement gemäß dem Kennzeichen des Patentanspruches 1.The invention solves this problem by a component according to the Characteristic of claim 1.

Das erfindungsgemäße Bauelement besitzt neben den bekannten guten Schallschutzeigenschaften auch eine gute Wärmeisolierung und ist aufgrund des feuerhemmenden Bindemittels feuerbeständig. Da Kork ein natürlicher Werkstoff ist, bereitet er bei einer späteren Entsorgung keine zusätzlichen Probleme, was auch durch das keine toxischen Gase entwickelnde Bindemittel begünstigt wird.The component according to the invention has, in addition to the known good ones Soundproofing properties are also good thermal insulation fire-resistant due to the fire-retardant binder. Because cork is a natural material, he prepares for a later one Disposal no additional problems, which is also due to the fact that none toxic gas-developing binder is favored.

Im folgenden soll die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert werden.In the following the invention with reference to one in the drawing illustrated embodiment are explained in more detail.

Die Darstellung zeigt einen Querschnitt durch ein plattenförmiges Bauelement in Verbundbauweise. Das Bauelement setzt sich zusammen aus einem Kern 1, der aus einem Korkwerkstoff, z. B. Preßkork be­ steht. Über eine Schicht eines Haftvermittlers 2 bzw. 3 ist auf die Ober- und Unterseite des Korkkerns jeweils eine Deckschicht 4 bzw. 5 aufgebracht, die im Fall des hier beschriebenen Ausfüh­ rungsbeispiels aus einem faserverstärkten Kunststoff besteht. Die Fasern können dabei aus Glas, Kohlenstoff oder Aramid bestehen, während als Kunststoffe sowohl Duroplaste wie Phenol-Formaldehyd, Polymid, ungesättigte Polyester oder Epoxid, als auch Thermo­ plaste, beispielsweise Polyethersulfon, Polyetherimid, Polyether­ etherketon oder Polyphenylensulfid, geeignet sind. Als Haftver­ mittler können Stoffe auf der Basis von Phenol oder Polyurethan eingesetzt werden, sofern ein solcher Haftvermittler erforderlich ist. Für die Deckschichten können anstelle der genannten faser­ verstärkten Kunststoffe im Rahmen der Erfindung auch Metall­ bleche, beispielsweise aus Aluminium, Titan oder Stahl, Verwen­ dung finden.The illustration shows a cross section through a plate-shaped component in composite construction. The component is composed of a core 1 , which is made of a cork material, for. B. Be cork. Over a layer of an adhesion promoter 2 or 3 , a cover layer 4 or 5 is applied to the top and bottom of the cork core, which in the case of the exemplary embodiment described here consists of a fiber-reinforced plastic. The fibers can consist of glass, carbon or aramid, while plastics are suitable as thermosets such as phenol-formaldehyde, polymide, unsaturated polyester or epoxy, as well as thermoplastics, for example polyether sulfone, polyether imide, polyether ether ketone or polyphenylene sulfide. Substances based on phenol or polyurethane can be used as adhesion promoters if such an adhesion promoter is required. For the outer layers, instead of the fiber-reinforced plastics mentioned, metal sheets, for example made of aluminum, titanium or steel, can also be used in the context of the invention.

Der Korkwerkstoff ist mit einem Bindemittel getränkt, das diesem Werkstoff eine hinreichende Feuerbeständigkeit bei Selbstlöschung verleiht. Dieses Bindemittel ist bei geringer Wärmefreisetzung durchbrandhemmend und es verhindert das Entstehen von Rauch- und Giftgasen.The cork material is soaked in a binder that this Adequate fire resistance when self-extinguishing gives. This binder is with low heat release flame retardant and prevents smoke and smoke from developing Toxic gases.
