Description
Stand der TechnikState of technology
Die Erfindung betrifft ein Verfahren zur Herstellung von Profilformteilen aus Faserverbundkunststoff durch Pultrusion auf der Basis wenigstens einer harzgetränkten Fasermatte, eines Fasergewebes oder Rovings, gemäß dem Oberbegriff von Anspruch 1 sowie ein nach diesem Verfahren hergestelltes Profilformbauteil nach Anspruch 9.The The invention relates to a method for the production of profiled moldings made of fiber composite plastic by pultrusion based on at least a resin-soaked Fiber mat, a fiber fabric or rovings, according to the preamble of claim 1 and a profile molding produced by this process according to claim 9.
Solche Profilformteile aus Faserverbundkunststoff werden beispielsweise für den Außenbereich wie den Innenbereich eines Kraftfahrzeugs, insbesondere bei Nutzfahrzeugen, Reisebussen und Omnibussen als Fahrzeugverkleidungselemente oder als Gebäudeelemente wie Vertäfelungen, Fensterprofile oder als Möbelelemente oder Verkleidungen von. technischen Aggregaten oder von Innenräumen von Flugzeugen eingesetzt.Such Profiled parts made of fiber composite plastic, for example for the outdoors such as the interior of a motor vehicle, especially in commercial vehicles, Coaches and buses as vehicle paneling elements or as building elements like wainscoting, Window profiles or as furniture elements or disguises of. technical units or interiors of Used aircraft.
Als Rovings werden Bündel von endlosen, unverdrehten, gestreckten Fasern (Filiamente) bezeichnet, die häufig in der Fertigung von Faserverbundwerkstoffen und besonders von Faser-Kunststoff-Verbunden eingesetzt werden. Die Einzelfilamente aus Glas, Aramid oder Kohlenstoff werden zuerst zu dickeren Bündeln, dem Roving, zusammengefasst und anschließend auf Spulen aufgewickelt.When Rovings become bundles of endless, untwisted, stretched fibers (filaments), the common in the production of fiber composites and especially of fiber-plastic composites be used. The single filaments made of glass, aramid or carbon become thicker bundles first, the roving, summarized and then wound up on spools.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs erwähnten Art derart weiter zu bilden, dass die Oberflächen von mit dem Verfahren herge stellten Profilformteilen möglichst variabel gestaltet werden können und zugleich vor einem Gebrauch bzw. einer Inbetriebnahme weitgehend geschützt sind.Of the The present invention is based on the object, a method the aforementioned Art to continue to form such that the surfaces of the method Herge profiled moldings as possible can be made variable and at the same time before use or commissioning largely protected are.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale von Anspruch 1 gelöst.According to the invention this Problem solved by the features of claim 1.
Vorteile der ErfindungAdvantages of invention
Im Rahmen eines Pultrusionsverfahrens wird im allgemeinen eine harzgetränkte Fasermatte, ein harzgetränktes Fasergewebe oder ein harzgetränktes Roving durch ein Pultrusionswerkzeug geführt und ein gewünschtes Profil erzeugt, welches nach dem Aushärten des Harzes formstabil bleibt.in the Frame of a pultrusion process is generally a resin-impregnated fiber mat, a resin-soaked Fibrous tissue or a resin-soaked Roving guided by a pultrusion tool and a desired Profile produced, which is dimensionally stable after curing of the resin remains.
Die Erfindung modifiziert das Pultrusionsverfahren derart, dass die harzgetränkte Fasermatte, das harzgetränkte Fasergewebe oder das harzgetränkte Roving in einem Arbeitsgang mit einer Beschichtung stoffschlüssig verbunden wird, welche die harzgetränkte Fasermatte, das harzgetränkte Fasergewebe oder das harzgetränkte Roving wenigstens teilweise und wenigstens einseitig bedeckt, wobei die Beschichtung mit einer nach außen weisenden, von ihr ablösbaren Schutzschicht versehen ist. Die harzgetränkte Fasermatte, das harzgetränkte Fasergewebe oder das harzgetränkte Roving wird folglich zusammen mit der mit der Schutzschicht versehenen Beschichtung unter Einwirkung von Wärme geformt und ausgehärtet.The Invention modifies the pultrusion process such that the resin-impregnated Fiber mat, the resin-impregnated Fibrous tissue or the resin-soaked Roving in one operation with a coating firmly bonded which is the resin-soaked Fiber mat, the resin-impregnated Fibrous tissue or the resin-soaked Roving at least partially and at least unilaterally covered, wherein the coating with an outwardly facing, removable from it protective layer is provided. The resin-soaked Fiber mat, the resin-impregnated Fibrous tissue or the resin-soaked Roving therefore becomes coextensive with the protective layer coating under the influence of heat shaped and cured.
Durch die Beschichtung kann die Oberfläche optisch und haptisch variabel ge-staltet werden. Die von der Beschichtung ablösbare Schutzschicht sorgt unter anderem dafür, dass die Oberflächenveredelung in Form der Beschichtung nicht vor dem Gebrauch oder einer Inbetriebnahme des Profilformteils beschädigt wird.By The coating can optically surface and haptically variable. The of the coating peelable Protective layer ensures, among other things, that the surface finishing in the form of the coating not before use or commissioning of the profile molding damaged becomes.
Die Schutzschicht kann bei Gebrauch oder einer Inbetriebnahme des Profilformteils oder auch direkt nach Durchführen des Pultrusionsverfahrens von der Beschichtung abgelöst, bevorzugt manuell abgezogen werden. Die lösbare Verbindung zwischen der Beschichtung und der Schutzschicht kann beispielsweise durch einen lösbaren Stoffschluss wie beispielsweise durch Kleben realisiert sein. Bei der Wahl des Klebers ist darauf zu achten, dass seine lösbaren oder dennoch adhäsiven Eigenschaften während des Pultrusionsverfahren nicht derart verändert werden, dass er diese Eigenschaften durch die Einwirkung von Wärme, wie sie bei diesem Verfahren angewandt wird, nicht verliert. Die Schutzschicht kann eine Kunststofffolie und/oder ein Vlies und/oder Papier und/oder ein Drahtgewebe und/oder eine durch das Pultrusionsverfahren aushärtbare Flüssigkeit beinhalten, insbesondere eine Kunststofffolie aus Polyamid.The Protective layer may be during use or commissioning of the profile molding or directly after performing of the pultrusion process detached from the coating, preferably be deducted manually. The detachable For example, connection between the coating and the protective layer through a detachable Material connection such as be realized by gluing. at The choice of glue is to be careful that its soluble or nevertheless adhesive Properties during the pultrusion process are not changed so that he Properties through the action of heat, as applied in this process will not lose. The protective layer may be a plastic film and / or a non-woven and / or paper and / or a wire mesh and / or include a curable by the pultrusion liquid, in particular a plastic film made of polyamide.
Weiterhin kann die Beschichtung mit der Schutzschicht zunächst mit Überstand auf die harzgetränkte Fasermatte, das harzgetränkte Fasergewebe oder das harzgetränkte Roving aufgebracht und der Überstand nach der Pultrusion des Profilformteils dann abschnitten werden.Farther For example, the coating with the protective layer may initially be coated with supernatant on the resin-impregnated fiber mat. the resin-soaked Fibrous tissue or the resin-soaked Roving applied and the supernatant then be cut after the pultrusion of the profile molding.
Gemäß einer ersten Alternative kann die harzgetränkte Fasermatte, das harzgetränkte Fasergewebe oder das harzgetränkte Roving zusammen und parallel mit der Beschichtung und der Schutzschicht in ein Pultrusionswerkzeug ein- und durch dieses hindurchgezogen werden.According to a first alternative, the resin-impregnated fiber mat, the resin-impregnated fiber fabric or the resin-impregnated roving may be combined and in parallel with the coating and the protective layer into a pultrusion tool and pulled through it.
Alternativ könnten wenigstens die harzgetränkte Fasermatte, das harzgetränkte Fasergewebe oder das harzgetränkte Roving und die Beschichtung getrennt voneinander in das Pultrusionswerkzeug eingeführt und erst anschließend zusammen und parallel durch dieses zum Durchführen der Pultrusion hindurch gezogen werden.alternative could at least the resin-soaked Fiber mat, the resin-impregnated Fibrous tissue or the resin-soaked Roving and the coating separately introduced into the pultrusion tool and only afterwards together and in parallel through this for performing the pultrusion to be pulled.
