Description
Die Erfindung betrifft einen Dachhimmel aus zwei miteinander verbundenen Schichten aus faserverstärkten Thermoplast-Lagen und Kunststoff-Schaumfolien, zwischen denen sich Bereiche mit Luftpolstern befinden.The invention relates to a headliner made of two interconnected Layers of fiber-reinforced thermoplastic layers and plastic foam foils, between which there are areas with air cushions.
Kraftfahrzeug-Innenteile werden in zunehmendem Maße aus Kunststoffen herge stellt. Für Dachhimmel werden dabei vor allem Schaumstoffbahnen, insbesondere aus Polyurethan oder Polyolefinen verwendet, die an ihrer Unterseite mit einer Kunststoffolie abgedeckt sind. Die genannten Schaumstoffe können zwar schwache Stöße abfedern, bei einem starken Aufprall, z. B. bei einem Unfall oder beim Fahren über ein tiefes Schlagloch, werden sie aber so stark zusammen gedrückt, daß der Kopf des Fahrgasts praktisch direkt an das harte Metallblech des Automobildachs anschlägt.Motor vehicle interior parts are increasingly being made from plastics provides. Foam sheeting, in particular, is used for headliners made of polyurethane or polyolefins used with a Plastic film are covered. The foams mentioned can absorb weak impacts in the event of a strong impact, e.g. B. in an accident or when driving over a deep pothole, they become so strong together pressed that the head of the passenger practically directly against the hard metal sheet of the automobile roof strikes.
Die EP-A 657 281 beschreibt ein Bauelement als Aufprallschutz und zur Schall dämmung im Automobilinnenraum, bestehend aus einer Kunststoff-Schaum schicht, z. B. aus Polyurethan, und einem damit kraftschlüssig verbundenen Trag körper aus einem naturfaserverstärkten Thermoplasten.EP-A 657 281 describes a component as impact protection and for sound Insulation in the automobile interior, consisting of a plastic foam layer, e.g. B. made of polyurethane, and a non-positively connected support body made of a natural fiber reinforced thermoplastic.
In der DE-A 43 11 592 sind Kraftfahrzeug-Innenverkleidungsteile beschrieben, die sich durch eine hohe Steifigkeit auszeichnen. Eine spezielle Ausführungsform besteht aus zwei flächig miteinander verbundenen Lagen aus naturfaserverstärk ten thermoplastischen Kunststoffen, wobei eine Lage Hohlkammern aufweist. Die Verkleidungsteile werden hergestellt, indem man auf ein mit Vertiefungen ver sehenes Unterwerkzeug zunächst ein vorerhitztes, flächiges Vlies aus Thermo plastfasern und Naturfasern auflegt und dieses Vlies durch Verpressen mittels eines mit entsprechenden Erhebungen versehenen ersten Oberwerkzeugs formt und zu einer kompakten Lage konsolidiert. Dann wird das erste Oberwerkzeug entfernt, ein zweites vorerhitzes Vlies wird auf die erste Lage aufgelegt und mittels eines zweiten, nicht mit Erhebungen versehenen Oberwerkzeugs wieder durch Verpressen konsolidiert und an den erhabenen Stellen der ersten Lage mit dieser verbunden. Auf diese Weise bilden sich an den vertieften Stellen der unteren Lage Hohlkammern aus. Um ein Einfallen der Lagen zu verhindern, muß während der Herstellung des Verbundteils durch Düsennadeln Luft unter Druck in die Hohl kammern eingepreßt werden. Hierbei handelt es sich ersichtlich um ein recht kompliziertes Verfahren.In DE-A 43 11 592 automotive interior trim parts are described are characterized by high rigidity. A special embodiment consists of two flat layers of natural fiber reinforced ten thermoplastics, one layer having hollow chambers. The Cladding parts are made by ver on a recessed lower tool first a preheated, flat fleece made of thermo plastic fibers and natural fibers and this fleece by pressing of a first upper tool provided with corresponding elevations and consolidated into a compact location. Then the first top tool removed, a second preheated fleece is placed on the first layer and by means of a second upper tool, which is not provided with elevations Squeeze consolidated and in the raised areas of the first layer with this connected. In this way, the lower parts of the lower layer are formed Hollow chambers. To prevent the layers from collapsing, during the Production of the composite part by means of nozzle needles air under pressure into the hollow chambers are pressed. This is obviously a right complicated procedure.
Der Erfindung lag nun die Aufgabe zugrunde, einen Automobil-Dachhimmel zu entwickeln, der nicht nur schwache Stöße abfedert, sondern zwar steif, aber doch so verformbar ist, daß er auch bei einem stärkeren Aufprall dem Fahrgast noch Schutz bietet. Ferner sollte der Dachhimmel schallschluckend sein, so daß er zur Lärmdämpfung geeignet ist. Der Dachhimmel sollte ferner einfach herstellbar sein. Diese Aufgaben sind bei dem erfindungsgemäßen Automobil-Dachhimmel gelöst.The invention was based on the object of an automotive headliner develop that not only absorbs weak impacts, but stiff, but still is so deformable that it still the passenger even in the event of a stronger impact Offers protection. Furthermore, the headliner should be sound absorbing, so that it can Noise reduction is suitable. The headliner should also be easy to manufacture. These tasks are solved in the automobile headlining according to the invention.
Der Dachhimmel besteht aus zwei Schichten, die beide eine faserverstärkte Thermoplastlage und, mit dieser haftend verbunden, eine geschlossenzellige Schaumfolie enthalten. Die Schaumfolien sind dabei einander gegenüberliegend angeordnet und miteinander verschweißt. Die Thermoplastlage kann alle üblichen faserbildenen Thermoplasten enthalten, vorzugsweise Polyolefine und insbeson dere Polypropylen, weiterhin enthält sie nicht thermoplastische Fasern als Ver stärkung. Geeignet sind bevorzugt solche aus Naturfasern, wie Flachs, Jute, Hanf, Sisal, Kenaf und Baumwolle, aber auch mineralische Fasern z. B. Glasfasern. Die Schaumfolie besteht aus einem vernetzten Polyolefin, vorzugsweise aus Poly propylen oder Polyethylen. Sie sollte möglichst geschlossenzellig sein, ihre Dichte liegt vorzugsweise zwischen 30 und 100 g/cm3. Die Dicke der Thermoplastlage beträgt vorzugsweise 2 bis 10 mm, die der Schaumfolie 1 bis 2 mm. Beide Schichten haben zusammen ein Flächengewicht von vorzugsweise 200 bis 2000, insbesondere von 400 bis 1500 g/m2. The headlining consists of two layers, both of which contain a fiber-reinforced thermoplastic layer and, when adhered to it, a closed-cell foam film. The foam sheets are arranged opposite each other and welded together. The thermoplastic layer can contain all the usual fiber-forming thermoplastics, preferably polyolefins and in particular polypropylene, and it also contains non-thermoplastic fibers as reinforcement. Suitable are preferably those made of natural fibers such as flax, jute, hemp, sisal, kenaf and cotton, but also mineral fibers such. B. glass fibers. The foam sheet consists of a cross-linked polyolefin, preferably made of poly propylene or polyethylene. It should be closed-celled if possible, its density is preferably between 30 and 100 g / cm 3 . The thickness of the thermoplastic layer is preferably 2 to 10 mm, that of the foam sheet 1 to 2 mm. Both layers together have a weight per unit area of preferably 200 to 2000, in particular 400 to 1500 g / m 2 .
Erfindungswesentlich ist, daß die beiden Schichten nur an einer Vielzahl von Teil bereichen miteinander verschweißt sind, so daß sich zwischen den Schichten nicht verschweißte, Luftpolster enthaltende Bereiche befinden, an denen die obere Schicht aufgewölbt ist. Die verschweißten Bereiche können verschiedenartige Gestalt haben, sie können z. B. rund, oval oder rechteckig sein. Sie machen vor zugsweise 10 bis 80% der Fläche des Dachhimmels aus, die Höhe der Aufwöl bung kann 50 bis 300%, bezogen auf die Dicke der oberen Schicht, betragen. Die ein Luftpolster enthaltende Aufwölbung ist bei einem starken Stoß nach innen verformbar und kann dadurch einen Aufprall abpuffern.It is essential to the invention that the two layers only on a large number of parts areas are welded together so that there is between the layers non-welded areas containing air cushions, where the upper Layer is bulged. The welded areas can be of different types Have shape, they can e.g. B. be round, oval or rectangular. You lead the way preferably 10 to 80% of the area of the headliner, the height of the bulge Exercise can be 50 to 300% based on the thickness of the top layer. The a bulge containing air cushions is when there is a strong impact inside deformable and can thus buffer an impact.
Auf die obere, dem Blechdach zugewandte Schicht des Dachhimmels kann ein Abdeckvlies, z. B. aus Polyesterfasern oder eine Aluminiumfolie aufgebracht sein; an der unteren, dem Fahrgastraum zugewandten Seite kann eine 1 bis 3 mm dicke Polsterschicht aus Kunststoffschaum, z. B. auf Basis von Polyurethan oder Polypropylen, sowie eine Dekorschicht, z. B. ein Vlies oder eine Folie, angebracht sein.One can on the upper layer of the headliner facing the tin roof Cover fleece, e.g. B. be applied from polyester fibers or an aluminum foil; on the lower side facing the passenger compartment there can be a 1 to 3 mm thick cushion layer made of plastic foam, e.g. B. based on polyurethane or Polypropylene, and a decorative layer, e.g. B. a fleece or a film attached his.
Fig. 1 zeigt einen Querschnitt durch einen Dachhimmel. Mit 1 bzw. 2 sind die Thermoplastlage bzw. die Schaumfolie der oberen Schicht bezeichnet, mit 1' bzw. 2' die Thermoplastlage bzw. die Schaumfolie der unteren Schicht. Die beiden Schichten sind nur an den Teilbereichen 3 miteinander verschweißt, wodurch sich die Hohlräume 4 ergeben. Fig. 1 shows a cross section through a headliner. 1 and 2 denote the thermoplastic layer or the foam sheet of the upper layer, 1 'and 2 ' the thermoplastic layer and the foam sheet of the lower layer. The two layers are only welded to one another at the partial areas 3 , which results in the cavities 4 .
Fig. 2 zeigt den Dachhimmel der Fig. 1 von oben gesehen. Mit 3 sind wieder die verschweißten Teilbereiche bezeichnet, mit 4 die nach oben aufgewölbten Hohl räume. Man sieht, daß diese miteinander verbunden sind. Dadurch ergibt sich die Möglichkeit, Kabelkanäle oder Röhren, z. B. für die Klimaanlage, einzulegen und dadurch unsichtbar in dem Dachhimmel zu integrieren. Fig. 2 shows the headliner of Fig. 1 seen from above. With 3 the welded sections are again designated, with 4 the bulging cavities. You can see that these are connected. This results in the possibility of cable ducts or tubes, for. B. for the air conditioning, insert and thus invisibly integrated into the headlining.
Fig. 3 zeigt einen Querschnitt durch einen Dachhimmel, der Einfachheit halber an einer Stelle, an der sich kein Hohlraum befindet. Hier sind das in einer bevor zugten Ausführungsform angebrachte Abdeckvlies 5 und die Polsterschicht 6 sowie die Dekorschicht 7, eingezeichnet. Fig. 3 shows a cross section through a headliner, for the sake of simplicity at a point where there is no cavity. Here, the covering fleece 5 attached in a preferred embodiment and the cushion layer 6 and the decorative layer 7 are shown.
Bei der Herstellung des erfindungsgemäßen Dachhimmels werden zunächst die Ausgangsmaterialien für die beiden Schichten hergestellt. Dazu werden konti nuierlich Bahnen der Schaumfolie und eines Mischvlieses aus Thermoplastfasern und Naturfasern oder Mineralfasern zusammengeführt. Dabei werden die jeweili gen einander zugewandten Oberflächen der Bahnen auf Temperaturen oberhalb des Erweichungspunktes des Thermoplasten, z. B. durch Anblasen mit Heißluft, erwärmt; dann werden die beiden Bahnen, vorzugsweise mittels Walzen, mit einander verpreßt. Dadurch ergibt sich eine gute Verbindung von Vlies und Schaumfolie und es wird eine Verbundbahn erhalten, die noch flexibel ist.In the manufacture of the headlining according to the invention, the Starting materials for the two layers manufactured. This will be cont layers of foam film and a mixed fleece made of thermoplastic fibers and natural fibers or mineral fibers merged. The respective towards mutually facing surfaces of the webs at temperatures above the softening point of the thermoplastic, e.g. B. by blowing with hot air, heated; then the two webs, preferably by means of rollers, with pressed together. This results in a good bond between fleece and Foam film and a composite sheet is obtained that is still flexible.
Von dieser Verbundbahn werden passende Zuschnitte abgeschnitten. Ein über den Schmelzpunkt des Thermoplasten vorgewärmter Zuschnitt, der im fertigen Dachhimmel die Oberschicht bildet, wird dann, mit der Schaumfolienseite nach oben, in das mit noppenförmigen Erhebungen versehene Unterwerkzeug einer Presse eingelegt. Auf diesen Zuschnitt wird ein weiterer vorgewärmter Zuschnitt, der in dem fertigen Dachhimmel die Unterschicht bildet, mit der Schaumfolienseite nach unten aufgelegt. Gleichzeitig wird die Presse mit einem glatten Oberwerk zeug luftdicht abgeschlossen und durch seitlich angebrachte Düsen wird Luft zwischen die Zuschnitte eingeblasen. Durch die beiden geschlossenzelligen Schaumfolien kann die Luft nicht entweichen, so daß durch den sich aufbauenden Luftdruck der untere Zuschnitt auf das Unterwerkzeug gepreßt wird und sich dort um die Noppen herum dicht anlegt. Die Zuschnitte berühren sich nur an den Auf lagestellen der erhöhten Noppen, dazwischen bildet sich ein zusammenhängender Hohlraum mit einem Luftpolster aus. Die - im Fall von Polypropylen als Thermo plast - 180 bis 200°C heißen Zuschnitte werden dann miteinander verpreßt. Suitable cuts are cut from this composite web. An over the melting point of the thermoplastic pre-heated blank, which in the finished The headliner forms the upper layer, with the foam film side behind above, in the lower tool provided with knob-shaped elevations Press inserted. Another preheated blank is placed on this blank, which forms the lower layer in the finished headlining, with the foam film side hung down. At the same time, the press comes with a smooth upper structure airtight seal and air is created through side-mounted nozzles blown in between the blanks. Through the two closed cells Foam foils cannot escape the air, so that the building up Air pressure the lower blank is pressed onto the lower tool and there tight around the knobs. The cuts only touch on the opening positions of the raised knobs, in between a coherent forms Cavity with an air cushion. The - in the case of polypropylene as thermo plast - hot cuts from 180 to 200 ° C are then pressed together.
Dabei schmelzen die Thermoplastfasern vollständig auf, während das vernetzte Polyolefin der Schaumfolie nicht aufschmilzt, sondern nur erweicht, so daß das Luftpolster formstabil erhalten bleibt. An den Berührungsstellen der beiden Schichten verschweißen die erweichten Schaumfolien miteinander. In der kalten Presse erstarrt dann der Thermoplast wieder, das Vlies konsolidiert und bildet die naturfaserverstärkte Thermoplastlage.The thermoplastic fibers melt completely while the crosslinked Polyolefin of the foam sheet does not melt, but only softens, so that Air cushion remains dimensionally stable. At the point of contact of the two Layers weld the softened foam sheets together. In the cold The thermoplastic then solidifies again, the fleece consolidates and forms the natural fiber reinforced thermoplastic layer.
Vor dem Verpressen können an der Oberseite des oberen Zuschnitts die Polster schicht 6 und die Dekorschicht 7 und an der Unterseite des unteren Zuschnitts das Abdeckvlies 5 angelegt werden. Diese Schichten werden mitverpreßt und werden über die aufschmelzenden Thermoplastfasern des Faservlieses mit den Grund schichten verbunden. Es versteht sich, daß der bei der beschriebenen Herstellung oben liegende Zuschnitt (mit Polster- und Dekorschicht) im eingebauten Zustand die Unterseite des Dachhimmels zum Fahrgastraum hin bildet.Before pressing, the cushion layer 6 and the decorative layer 7 and the cover fleece 5 can be applied to the underside of the lower blank on the top of the upper blank. These layers are pressed together and are connected to the base layers via the melting thermoplastic fibers of the nonwoven fabric. It goes without saying that the blank lying at the top in the manufacture described (with cushion and decorative layer) forms the underside of the headliner towards the passenger compartment when installed.
