Description
Verfahren und Vorrichtung zum Beschichten von Körpern mit faserverstärkten Duroplasten Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Beschichten von Körpern, wie zOBo Schwimm- und Flugkörpern, Tafelelementen, Großbehältern und dergl., mit faserverstärkten Duroplasten.Method and device for coating bodies with fiber-reinforced Thermosetting plastics The invention relates to a method and a device for coating of bodies such as zOBo floating and missiles, panel elements, large containers and the like., with fiber-reinforced thermosetting plastics.
Zur Herstellung bzw. zum Beschichten von derartigen Körpern ist bislang - trotz vielfältiger Versuche - lediglich die Handauflegetechnik bekannt0 Dies trifft insbesondere für Körper mit unregelmäßig gekrümmten Hüllflächen zu. So lassen sich bekannte maschinelle Wickelverfahren lediglich bei rotations+symmetrischen Körpern verwenden; das gleichfalls bekannte Faser-Spritzverfahren ist nur bedingt anwendbar, da dabei infolge des Fehlens einer durchgehenden Faserbahn nur verhältnismäßig geringe Festigkeits werte erreichbar sind0 Der Erfindung liegt die Aufgabe zugrunde, die Nachteile des Bekannten zu vermeiden, insbesondere also ein Verfahren und eine Vorrichtung zum maschinellen und ggf. halbautomatischen Beschichten von Körpern zu schaffen Erfindungsgemäß wird diese Aufgabe in erster Linie dadurch gelöst, daß ein mit eingedicktem Harz imprägniertes Band kontinuierlich und unter Druck auf den Körper aufgewalzt und gleichzeitig erhitzt wird.For the production or for the coating of such bodies, up to now - despite various attempts - only the hand-laying technique is known0 This is true especially for bodies with irregularly curved envelope surfaces. So let yourself known mechanical winding processes only for rotationally symmetrical bodies use; the fiber spray process, which is also known, can only be used to a limited extent, because there is only a relatively small amount due to the lack of a continuous fiber web Strength values are achievable0 The invention is based on the object To avoid disadvantages of the known, in particular a method and a device for the machine and possibly semi-automatic coating of bodies According to the invention, this object is primarily achieved in that a with thickened Resin-impregnated tape is rolled onto the body continuously and under pressure and is heated at the same time.
Durch das kontinuierliche Auftragen und unmittelbare Aushärten des Bandes wird auf optimal einfache Weise eine ununterbrochene Ueschichtung von Körpern ermöglicht, welche sich durch die für Handauflege-Verfahren bekannten hohen Festigkeitswerte kennzeichnet.Due to the continuous application and immediate hardening of the Tape becomes an uninterrupted layering of bodies in an optimally simple way allows which known for the laying on of hands method high strength values.
Die Imprägnierung des Bandes mit eingedicktem harz, das in üblicherweise bereits die Härter-Komponente enthält, und in seiner Rezeptur so eingestellt werden kann, daß unter Druck und Wärme kürzeste Reaktionszeiten erreicht werden, läßt dabei relativ hohe Arbeitsgeschwindigkeiten und damit verbundene wirtschaftliche Serienfertigung zu.The impregnation of the tape with thickened resin, which is commonly used already contains the hardener component and can be set in its recipe can that the shortest reaction times can be achieved under pressure and heat, leaves it relatively high working speeds and the associated economical series production to.
Vorteilhaft läßt sich die Erfindung mit einer Vorrichtung realisieren, welche einen Aufwalzkopf mit Inindestens einer relativ zum Körper bewegbaren und gegen diesen pressbaren Andruckrolle sowie eine Heizeinrichtung aufweist, über we che das auf einer Vorratsrolle- gehaltene fiarzband abziehbar ist.The invention can advantageously be implemented with a device which has a rolling head with at least one movable relative to the body and has against this pressable pressure roller and a heating device, over we that the fiarz tape held on a supply roll can be pulled off.
Die Zusammenfassung von Andrückrolle, Heizeinrichtung und Vorratsrolle in einem Bauteil garantiert dabei einfache Handhabung. Durch das iiiwjittelbare Aushärten des Harzes beim Auftragen läßt sich einerseits die ert indungsgemäße Vorrichtung in jeder beliebigen Relativlage einsetzen und ist andererseits die Güte des Laminats unabhängig von Schwankung der Umgebungstemperatur, bzw. wird ganz allgemein die Herstellung von Duroplast- Laminaten unabhängig von der limgebungstemperatur ermöglicht 0 In weiterer Ausgestaltung läßt sich die erfindungsgemäße Vorrichtung dadurch verbessern, daß die Andrückrolle durch eine Antriebseinrichtung angetrieben wird und somit automatisch konstante Vorschub-Ge schw indigkei t des Beschichtungsvorgangs gewährleistet wird.The combination of pressure roller, heating device and supply roller easy handling is guaranteed in one component. Through the communicable The device according to the invention can be used, on the one hand, to harden the resin during application use in any relative position and on the other hand is the quality of the laminate regardless of fluctuations in the ambient temperature, or is generally the Production of thermoset laminates is made possible regardless of the ambient temperature 0 In a further embodiment, the device according to the invention can be improved by that the pressure roller is driven by a drive device and thus automatically constant feed speed of the coating process is guaranteed.
Vorteilhaft ist es auch, wenn der Andruckrolle eine plattenförmige, federnde, das Harzband gegen den Körper pressende ileizeinriclitung nachgeschaltet wird, welche flächiges Anliegen des Harzbandes am Körper im Moment des Erhitzens und Aushärtens gewährleistet.It is also advantageous if the pressure roller has a plate-shaped, resilient ileizeinriclitung that presses the resin band against the body is connected downstream which surface contact of the resin tape on the body at the moment of heating and hardening guaranteed.
Insbesondere im Hinblick auf schnelles Erhitzen und erhöhte Betriebsgeschwindigkeiten ist es erfindungsgemäß auch vorgesehen, sowohl die Andruckrolle selbst aufzuheizen als auch eine separate Heizeinrichtung nachzuschalten0 Auch kann zur Anpassung der Vorschubgeschwindigkeit des Aufwalzkopfes an die verschiedenen Betriebs-Parameter neben einem Regler für die Heizeinrichtung eine Steuereinrichtung für den Antrieb der Andruckrolle vorgesehen werden. Besonders einfache Handhabung des Aufwalzkopfes wird gewährleistet, wenn dieser an einer höhen-verstellbaren Halterung kardanisch angeleSçt ist, und wenn die lialterung über einen Auslegrm an einer Halteeinrichtung über dein zu beschichtenden Körper längs verschiebbar befestigt ist; ggf. erforderliches seitliches Verschwenken läßt sich dabei erreichen, wenn der Auslegearm um seinen Befestigungspunkt an der Halteeinrichtung vertikal verschwenkbar angeordnet ist.Especially with regard to rapid heating and increased operating speeds it is also provided according to the invention to heat up both the pressure roller itself as well as a separate heating device to be connected downstream0 Can also be used to adapt the Feed rate of the rolling head to the various operating parameters in addition to a controller for the heating device, a control device for the drive the pressure roller are provided. Particularly easy handling of the rolling head is guaranteed if it is gimbaled to a height-adjustable bracket angeleSçt is, and if the storage via an extension arm on a holding device is attached longitudinally displaceably over your body to be coated; possibly required lateral pivoting can be achieved when the extension arm around his Attachment point is arranged vertically pivotable on the holding device.
