Description
Die Erfindung betrifft eine Vorrichtung zur Herstellung eines faserverstärkten Kunststoffbauteils nach dem Oberbegriff des Patentanspruches 1.The invention relates to a device for producing a fiber-reinforced plastic component according to the preamble of
Für die Herstellung eines faserverstärkten Kunststoffbauteils wird in gängiger Praxis ein faserverstärktes Thermoplast als Faserhalbzeug verwendet, bei dem die Verstärkungsfasern in einer Imprägnieranlage unvollständig mit einem Matrixmaterial vorimprägniert werden. Der vorimprägnierte Thermoplast wird zur Weiterbearbeitung in eine Heizanlage gefördert, in der das Matrixmaterial bis auf eine Schmelztemperatur erhitzt wird. In diesem Zustand wird der faserverstärkte Thermoplast einer Warmumformung unterworfen, in der das Kunststoffbauteil geformt wird.For the production of a fiber-reinforced plastic component, a fiber-reinforced thermoplastic is used as a semi-finished fiber in common practice, in which the reinforcing fibers are incompletely pre-impregnated with a matrix material in an impregnation system. The pre-impregnated thermoplastic is conveyed to a heating system for further processing, in which the matrix material is heated up to a melting temperature. In this state, the fiber-reinforced thermoplastic is subjected to hot forming, in which the plastic component is molded.
Eine gattungsgemäße Vorrichtung zur Herstellung eines solchen faserverstärkten Kunststoffbauteils weist eine Kontaktheizung auf, die zur Erwärmung in direktem wärmeleitendem Kontakt mit dem Faserhalbzeug bringbar ist. Die Kontaktheizung weist im Stand der Technik meist eine metallische Heizfläche auf, die entweder über einen elektrischen Widerstand oder über ein heißes Fluid (etwa Öl) beheizt wird. Durch ein leichtes Anpressen des Faserhalbzeuges auf die Heizfläche wird die Wärmeleitung verbessert.A generic device for producing such a fiber-reinforced plastic component has a contact heater which can be brought into direct, heat-conducting contact with the semi-finished fiber for heating. In the prior art, contact heating usually has a metallic heating surface, which is heated either by an electrical resistor or by a hot fluid (such as oil). The heat conduction is improved by lightly pressing the semi-finished fiber product onto the heating surface.
Derartige metallische Heizflächen weisen eine große Wärmekapazität auf. Jedoch können sich Reste des aufgeschmolzenen Thermoplastpolymers des Faserhalbzeuges an der metallischen Heizfläche ablagern, wodurch sich ein Faserabrieb ergeben kann. Aus diesem Grunde findet bislang eine Kontaktheizung in der Großserienfertigung von Kunststoffbauteilen keine Anwendung.Such metallic heating surfaces have a large heat capacity. However, residues of the melted thermoplastic polymer of the semi-finished fiber can deposit on the metallic heating surface, which can result in fiber abrasion. For this reason, contact heating has so far not been used in the large-scale production of plastic components.

Die Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Herstellung eines faserverstärkten Kunststoffbauteils bereitzustellen, die eine für die Großserienproduktion geeignete Kontaktheizung aufweist.The object of the invention is to provide a device for producing a fiber-reinforced plastic component, which has a contact heater suitable for large-scale production.
Die Aufgabe ist durch die Merkmale des Patentanspruches 1 gelöst. Bevorzugte Weiterbildungen der Erfindung sind in den Unteransprüchen offenbart.The object is solved by the features of
Die Erfindung beruht auf dem Sachverhalt, dass bei herkömmlichen Kontaktheizungen, speziell mit beidseitig des Faserhalbzeugs angeordneten Heizelementen, sich beim Aufheizen Polymerreste an den Heizflächen ablagern. Vor diesem Hintergrund ist auf die Kontaktheizung eine, die Heizfläche bildende Entformungsschicht aufgetragen, mit der ein Anhaften des Faserhalbzeugs an der Kontaktheizung verhindert ist. Auf diese Weise kann der Wärmetransport in das Faserhalbzeug bevorzugt durch Wärmeleitung erfolgen, wobei das oben beschriebene Problem des Anhaftens vollständig beseitigt werden kann. Die Entformungsschicht weist bevorzugt eine im Vergleich zum Matrixmaterial des Faserhalbzeugs größere Oberflächenspannung auf. Als bevorzugte Materialien für die Entformungsschicht kommen insbesondere Galvano-Chemisch-Nickel, Keramiken, eine Carbonpartikelemulsion oder ein Nanolack in Frage. Im Unterschied zum Stand der Technik wird somit nicht mehr eine metallische Heizfläche bereitgestellt, sondern vielmehr die Heizfläche durch die Entformungsschicht gebildet.The invention is based on the fact that in conventional contact heaters, especially with heating elements arranged on both sides of the semi-finished fiber, polymer residues are deposited on the heating surfaces during heating. Against this background, a demolding layer forming the heating surface is applied to the contact heater, with which the semi-finished fiber product is prevented from adhering to the contact heater. In this way, the heat can be transported into the semi-finished fiber preferably by heat conduction, and the problem of adhesion described above can be completely eliminated. The demolding layer preferably has a greater surface tension than the matrix material of the semi-finished fiber product. Preferred materials for the demolding layer are in particular electrochemical nickel, ceramics, a carbon particle emulsion or a nano lacquer. In contrast to the prior art, a metallic heating surface is no longer provided, but rather the heating surface is formed by the demolding layer.
Für ein beschleunigtes Aufheizen des Faserhalbzeuges kann die Kontaktheizung zwei beidseitig des Faserhalbzeugs angeordnete Heizelemente aufweisen. Mit den beidseitig angeordneten Heizelementen kann das zwischengeordnete Faserhalbzeug unter Druckbeaufschlagung erwärmt werden. Durch Ausübung von Druck auf das Faserhalbzeug wird der Wärmetransport durch Reduktion des Übergangswiderstandes wesentlich verbessert.For accelerated heating of the semi-finished fiber, the contact heater can have two heating elements arranged on both sides of the semi-finished fiber exhibit. With the heating elements arranged on both sides, the intermediate semi-finished fiber product can be heated under pressure. By exerting pressure on the semi-finished fiber, the heat transfer is significantly improved by reducing the contact resistance.
In einer technischen Ausführung können die beiden obigen Heizelemente der Kontaktheizung Bestandteile einer Presse mit zwei zusammenwirkenden Presswerkzeugen sein. Die beiden Heizelemente können als lösbar montierte Einsatzteile jeweils an den gegenüberliegenden Werkzeugflächen der beiden Presswerkzeuge angeordnet sein. Auf diese Weise kann eine an sich herkömmliche Presse ohne weiteres mit den Heizelementen nachgerüstet werden.In a technical embodiment, the two heating elements of the contact heater above can be components of a press with two interacting pressing tools. The two heating elements can each be arranged as detachably mounted insert parts on the opposite tool surfaces of the two pressing tools. In this way, a conventional press can be easily retrofitted with the heating elements.
Die Kontaktheizung ist elektrisch betrieben, und zwar als Widerstandsheizung. Zur Bildung der Kontaktheizung sind die elektrischen Heizleiter unmittelbar in der Entformungsschicht integriert.The contact heater is electrically operated as a resistance heater. To form the contact heating, the electrical heating conductors are integrated directly in the demolding layer.
Als elektrische Heizleiter kommen beispielhaft Kohlenstofffasern oder rasterartig angeordnete Metalldrähte (etwa aus Nickel) in Frage, die für eine gleichmäßige Wärmeverteilung zum Beispiel in einer Gitterstruktur in der oben erwähnten Keramikheizplatte oder unmittelbar in der Entformungsschicht integriert sein können.Examples of suitable electrical heating conductors are carbon fibers or metal wires (for example made of nickel) arranged in a grid-like manner, which can be integrated in a grid structure in the ceramic heating plate mentioned above or directly in the demolding layer for uniform heat distribution.
Derartige keramische Heizplatten können bevorzugt aus Nicht-Oxid-Keramik (SiC, SiN4) oder Oxid-Keramik (Al2O3, ZrO2, BeO) gefertigt sein, beispielhaft aus Aluminiumoxid oder Siliziumnitrit gefertigt sein sowie unterschiedliche Bauformen aufweisen. Die Keramikheizplatten können dabei eine Materialstärke im Bereich von 5 mm aufweisen. Bei Verwendung einer Keramikheizplatte ergeben sich aufgrund des Keramikmaterials sowie der vergleichsweise geringen Masse sehr schnelle Aufheizraten, eine homogene Temperaturverteilung sowie eine sehr gute Regelgenauigkeit. Zudem bleibt die Keramik-Oberfläche aufgrund der geringen Wärmedehnung auch im Temperaturwechselbetrieb - im Vergleich zu Metallen - ebenflächig. Die hohe Festigkeit von Keramik erlaubt zudem eine Druckbeanspruchung bei sehr geringem Verschleiß.Such ceramic heating plates can preferably be made of non-oxide ceramic (SiC, SiN 4 ) or oxide ceramic (Al 2 O 3 , ZrO 2 , BeO), for example made of aluminum oxide or silicon nitride, and have different designs. The ceramic heating plates can have a material thickness in the range of 5 mm. When using a ceramic heating plate, the ceramic material and the comparatively low mass result in very fast heating rates, a homogeneous temperature distribution and very good control accuracy. In addition, due to the low thermal expansion, the ceramic surface remains flat even in temperature change operation - in comparison to metals. The high strength of ceramics also allows pressure loads with very little wear.
