Description
Die Erfindung betrifft ein Verfahren zur Erzeugung von dreidimensional drapierfähigen Thermoplast-Funktionselement-Halbzeugen zur Integration in Faser-Thermoplast -Verbunde.The invention relates to a method for the production of three-dimensional drapierfähigen thermoplastic functional element semi-finished products for integration into fiber-thermoplastic composites.
Adaptive Bauteilstrukturen bestehen in der Regel aus passiven Werkstoffen, wie etwa faserverstärkten Kunststoffen oder Leichtmetallen und zusätzlichen aktorischen oder sensorischen Funktionselementen. Derartige Bauteilstrukturen erlauben die zustandsabhängige Anpassung des Strukturverhaltens an betriebsbedingte Belastungen. Die Applikation oder Integration der in separierten Fertigungsteilschritten hergestellten Funktionselemente auf oder in den passiven Werkstoffverbund ist bisher durch einen hohen Montageaufwand sowie durch eine fehlende werkstoffliche Abstimmung zwischen Funktionselementwerkstoff und Verbundwerkstoff gekennzeichnet. Weiterhin besteht die Problematik einer erhöhten Instabilität und unzureichenden Positionier- und Fixierbarkeit der filigranen Funktionselemente in der Bauteilherstellung, d.h. verarbeitungsinduzierte Belastungen wie etwa Verarbeitungsdrücke oder Fließbewegungen von Kunststoffschmelzen führen oft zur Schädigung von einzelnen Funktionselementen oder zur Verwerfung der Faser-Thermoplast-Verbunde. Existierende robuste Funktionselemente sind sowohl durch eine unzureichende werkstoffliche als auch durch eine zu niedrige geometrische Anpassungsfähigkeit an die Faserverbundstruktur gekennzeichnet.Adaptive component structures are usually made of passive materials, such as fiber-reinforced plastics or light metals and additional actuator or sensory functional elements. Such component structures allow the state-dependent adaptation of the structural behavior to operational loads. The application or integration of the functional elements produced in separate production sub-steps on or in the passive material composite has hitherto been characterized by a high assembly cost and by a lack of material coordination between functional element material and composite material. Furthermore, there is the problem of increased instability and insufficient positioning and fixability of the filigree functional elements in the component production, i. Processing-induced stresses such as processing pressures or plastic melt flow motions often lead to damage to individual functional elements or to the rejection of the fiber-thermoplastic composites. Existing robust functional elements are characterized by an insufficient mechanical as well as by a too low geometric adaptability to the fiber composite structure.
Bei der Fertigung adaptiver Bauteilstrukturen aus Verbundwerkstoffen werden derzeit die Funktionselemente (Aktoren oder Sensoren) überwiegend erst nach der Verbundherstellung in einem zusätzlichen Montageschritt klebtechnisch auf die Bauteiloberfläche appliziert. Die zur Verbundanbindung zur Verfügung stehende Moduloberfläche besteht dabei meist aus einer Polyimidträgerfolie, wie in den Druckschriften
Gemäß der
Erste Verfahren zur Herstellung werkstoffkompatibler Funktionselemente sind in den Druckschriften
Nationale und internationale Forschungsansätze zur Integration von Funktionsmodulen in Verbundwerkstoffe zielen insbesondere auf Faserverbundwerkstoffe mit duroplastischen Matrices ab, wobei hier der Fokus auf Einzelfertigungen für Luftfahrtanwendungen liegt und Serienfertigungspakete im Hintergrund stehen. Bei diesem Fertigungsverfahren werden die Funktionselemente weitestgehend einzeln und mit hohem manuellem Aufwand erst während der Fertigung der adaptiven Verbundstruktur derselben zugeführt. Zudem erfolgt keine Anpassung der Funktionselemente auf den Matrixwerkstoff der Verbundstruktur, wie in den Druckschriften
Die Nachteile bestehen in
- - einer werkstofflichen Inkompatibilität zwischen Funktionselement und Verbundwerkstoff, die zu mangelhafter Anbindung und somit verminderter Leistungsfähigkeit der Funktionselemente führt,
- - einem hohen manuellen Strukturfertigungsaufwand durch Aufbau eines Funktionselement-Halbzeuges aus einzelnen Funktionselementen erst während der Bauteilherstellung,
- - einer erhöhten Empfindlichkeit der sensitiven Funktionselemente gegenüber fertigungsprozessinduzierten Belastungen,
- - einer begrenzten geometrischen Anpassungsfähigkeit existierender adaptronischer Systeme an die Faserverbundstruktur,
- - einer schwierigen Positionier- und Fixierbarkeit der Funktionselemente im Verarbeitungsprozess.
- a material incompatibility between functional element and composite material which leads to poor connection and thus reduced performance of the functional elements,
- a high level of manual structure production expenditure by constructing a functional element semifinished product from individual functional elements only during component production,
- an increased sensitivity of the sensitive functional elements to production-process-induced stresses,
- a limited geometric adaptability of existing adaptronic systems to the fiber composite structure,
- - a difficult positioning and fixability of the functional elements in the processing process.
Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren zur Erzeugung von dreidimensional drapierfähigen Thermoplast-Funktionselement-Halbzeugen zur Integration in Faser-Thermoplast-Verbunde anzugeben. Das Verfahren beinhaltet den Aufbau und die Positionierung vorkonsolidierter dreidimensional drapierfähiger Thermoplast-Funktionselement-Halbzeuge zur nachfolgenden Integration in Faser-Thermoplast-Verbunde als Teil einer Prozesskette zur seriengerechten Fertigung adaptiver Strukturverbunde, die neben strukturellen auch sensorische und aktorische Funktionen besitzen. Es soll dabei ein an den Matrixwerkstoff der passiven Tragstruktur angepasster Aufbau des Funktionselement-Halbzeuges bereitgestellt werden, der direkt, d.h. ohne zusätzlichen Montageaufwand, zur robusten, automatisierten Fertigung adaptiver Faser-Thermoplast-Verbunde verwendet werden kann und parallel den Schutz des Halbzeuges und der einzelnen Funktionselemente vor fertigungsprozessinduzierten Beanspruchungen garantiert. Gleichzeitig soll ein Höchstmaß an Drapierfähigkeit zur Verarbeitung in einfach und mehrfach gekrümmten Verbunden erreicht werden. Zusätzlich soll eine verbesserte Anbindung von Funktionselementen in/an die Faser-Thermoplast-Verbundstruktur sowie eine Erhöhung des elektrischen Isolationsschutzes erreicht werden.The invention is therefore based on the object of specifying a method for producing three-dimensional drapible thermoplastic functional element semifinished products for integration into fiber-thermoplastic composites. The process involves the construction and positioning of preconsolidated three-dimensional drapeable thermoplastic functional element semifinished products for subsequent integration into fiber-thermoplastic composites as part of a process chain for series production of adaptive structural composites, which have structural as well as sensory and actuator functions. It is intended to provide a structure of the functional element semifinished product which is adapted to the matrix material of the passive support structure and which can be used directly, ie without additional assembly effort, for the robust, automated production of adaptive fiber-thermoplastic composites and in parallel the protection of the semifinished product and the individual Function elements before guaranteed by manufacturing process-induced stresses. At the same time, the highest degree of drapability is to be achieved for processing in single and multiple curved composites. In addition, an improved connection of functional elements in / on the fiber-thermoplastic composite structure and an increase in the electrical insulation protection is to be achieved.
Die Aufgaben werden durch die Merkmale des Patentanspruchs 1 gelöst.The objects are achieved by the features of
In dem Verfahren zur Erzeugung von dreidimensional drapierfähigen Thermoplast-Funktionselement-Halbzeugen zur Integration in Faser-Thermoplast-Verbunde werden gemäß dem Kennzeichenteil des Patentanspruchs 1 zumindest folgende Schritte durchgeführt:
- - Bereitstellen einer ersten multifunktionalen thermoplastischen Trägerfolie (Schutz, Stabilisierung, Anbindung, Isolation),
- - Auflegen und Positionieren eines Funktionselement-Netzwerkes aus mit flexiblen Leiterbahnen verbundenen flächigen Funktionselementen auf die erste thermoplastische Trägerfolie,

- - Kontaktschmelzen und Konsolidieren der beiden sich gegenüberliegenden thermoplastischen Trägerfolien mit dem darin befindlichen Funktionselement-Netzwerke in einem Heißpressprozess unter Druck und erhöhter Temperatur,
- - Bereitstellen einer unter der ersten multifunktionalen thermoplastischen Trägerfolie anbringbaren ebenen ersten elastischen Prozesshilfsfolie,
- - Auflegen der unteren ersten thermoplastischen Trägerfolie auf die elastische Prozesshilfsfolie,
- - Abdecken der oberen zweiten multifunktionalen thermoplastischen Trägerfolie mit einer oberen ebenen zweiten elastischen Prozesshilfsfolie, so dass der Aufbau aus Funktionselement-Halbzeug und thermoplastischen Trägerfolien, mit dem Ziel einer Funktionselemente schonenden Verpressung, zwischen elastischen Prozesshilfsfolien angeordnet ist, wobei die thermoplastischen Trägerfolien die einzelnen Funktionselemente und zugehörigen elektrischen Komponenten umgeben, und
- - Entfernen der ebenen Prozesshilfsfolien.
- Providing a first multifunctional thermoplastic carrier film (protection, stabilization, connection, insulation),
- Placing and positioning of a functional element network of planar functional elements connected to flexible conductor tracks onto the first thermoplastic carrier foil,
- Placing a second multifunctional thermoplastic carrier film on the functional element network,
- Contact melting and consolidation of the two opposite thermoplastic carrier films with the functional element networks contained therein in a hot press process under pressure and elevated temperature,
- Providing a planar first elastic process auxiliary film which can be applied under the first multifunctional thermoplastic carrier film,
- Placing the lower first thermoplastic carrier film on the elastic process auxiliary film,
- Covering the upper second multifunctional thermoplastic carrier film with an upper planar second elastic process auxiliary film, so that the structure of functional element semifinished and thermoplastic carrier films, with the aim of a functional elements gentle compression between elastic process auxiliary films is arranged, wherein the thermoplastic carrier films, the individual functional elements and surrounding electrical components, and
- - Remove the flat process auxiliary films.
Für die automatische Prozesseinbindung - Integration - der trägerfoliengeschützten Funktionselement-Halbzeuge in einen Faser-Thermoplast-Verbund wird zumindest folgender weiterer Schritt durchgeführt:
- - Zuführung des Funktionselement-Halbzeuges als dreidimensional verformbare Funktionslage dem Faserverbundfertigungsprozess zur Integration in den Faser-Thermoplast-Verbund.
- - Feeding of the functional element-semifinished product as a three-dimensionally deformable functional position of the fiber composite manufacturing process for integration into the fiber-thermoplastic composite.
Das Funktionselement-Halbzeug kann aufbauseitig mit flächigen Funktionselementen auf der unteren ersten multifunktionalen thermoplastischen Trägerfolie manuell und/oder robotergeführt versehen werden, die mit dem Ziel der Netzbildung über Leiterbahnen kontaktiert werden, wobei danach die obere zweite multifunktionale thermoplastische Trägerfolie manuell oder automatisiert aufgelegt wird und mittels des Heißpressprozesses eine Verbindung der sich gegenüberliegenden angeschmolzenen Thermoplastfolien realisiert.The functional element semifinished product can be manually and / or robotically provided on the construction side with planar functional elements on the lower first multifunctional thermoplastic support film, which are contacted with the aim of mesh formation via conductor tracks, after which the upper second multifunctional thermoplastic support film is applied manually or automatically and by means of the hot pressing process realized a connection of the opposite molten thermoplastic films.
Das Bereitstellen der Prozesshilfsfolien und thermoplastischen Trägerfolien erfolgt sowohl manuell in einem planaren Formwerkzeug als auch automatisiert, etwa mittels eines Rolle-Rolle-Verfahrens.The process auxiliary films and thermoplastic carrier films are provided both manually in a planar molding tool and also automatically, for example by means of a roll-to-roll method.
Die Prozesshilfsfolien sind gekennzeichnet durch eine hohe Temperaturbeständigkeit und Elastizität und dabei insgesamt dicker als das Thermoplast-Funktionselement-Halbzeug, so dass die Prozesshilfsfolien (z.B. Silikon- oder EPDM-Folien) zum einen den Heißpressprozess schädigungsfrei durchlaufen und somit wieder verwendbar sind und zum anderen infolge von Aufdickungen durch Funktionselemente prozessinduzierte Drucküberhöhungen ausgleichen, was zur schonenden Verpressung der Funktionselemente zwischen den thermoplastischen Trägerfolien führt.The process auxiliary films are characterized by a high temperature resistance and elasticity and thereby a total of thicker than the thermoplastic functional element semis, so that the process auxiliary films (eg silicone or EPDM films) on the one hand pass through the hot pressing process without damage and thus reusable and on the other hand compensate for process-induced pressure peaks by thickening by functional elements, which leads to the gentle compression of the functional elements between the thermoplastic carrier films.
Das Verpressen in einem Heißpressprozess kann sowohl diskontinuierlich in einer stationären Presse mit beheiztem Formwerkzeug als auch kontinuierlich, etwa in einer Doppelbandpresse, erfolgen, so dass ein bei Raumtemperatur hochflexibles aber dennoch maschinell handhabbares flächiges Funktionselement-Halbzeug erreicht wird.The pressing in a hot pressing process can be carried out both discontinuously in a stationary press with a heated mold and continuously, for example in a double belt press, so that a flat functional element semifinished product that is highly flexible at room temperature but nevertheless can be handled by machine.
Nach der Herstellung des Thermoplast-Funktionselement-Halbzeuges werden die Prozesshilfsfolien unmittelbar entfernt. Dies erfolgt manuell oder automatisiert, etwa in Form umlaufender Prozesshilfsfolien in einer Doppelbandpresse und/oder einem Rolle-Rolle-Prozess.After the production of the thermoplastic functional element semifinished product, the process auxiliary films are removed immediately. This is done manually or automatically, for example in the form of circulating process auxiliary films in a double belt press and / or a roll-to-roll process.
Bei der Fertigung der adaptiven Faserverbundstruktur wird das Funktionselement-Halbzeug als dreidimensional verformbare Funktionslage dem Faserverbundfertigungsprozess zugeführt und zur Erweichung während oder kurz vor dem Integrationsprozess trägerfolienaußenseitig angeschmolzen, so dass nach Abschluss der Formgebung die vollständige Anbindung der thermoplastischen Trägerfolien des Funktionselement-Halbzeuges mit dem identischen thermoplastischen Matrixmaterial der Faserverbundstruktur vollzogen ist.When fabricating the adaptive fiber composite structure, the functional element semifinished product is fed to the fiber composite production process as a three-dimensionally deformable functional layer and melted to softening during or just before the integration process carrier film outside, so that after completion of the molding complete connection of the thermoplastic Carrier films of the functional element semifinished product with the identical thermoplastic matrix material of the fiber composite structure is completed.
Die Lagerung des hochflexiblen thermoplastischen Funktionselement-Halbzeuges wird bis zur Verarbeitung in einem adaptiven Faser-Thermoplast-Verbund bei Raumtemperatur durchgeführt.The storage of the highly flexible thermoplastic functional element semifinished product is carried out at room temperature until it is processed in an adaptive fiber-thermoplastic composite.
Im Fall thermoplastisch umhüllter Funktionselement-Halbzeuge und Faser-Thermoplaste-Verbunde erfolgt die Fixierung der beiden sich gegenüberliegenden Thermoplaste durch Anschmelzen.In the case of thermoplastically coated functional element semifinished products and fiber-thermoplastic composites, the fixation of the two opposing thermoplastics takes place by melting.
Das Funktionselement-Halbzeug zur Integration in Faser-Thermoplast-Verbunde, das mittels des vorgenannten Verfahrens hergestellt wird, besteht zumindest aus
- - einem flächenbezogenen, zentral befindlichen Funktionselement-Netzwerk aus Funktionselementen und Leiterbahnen mit elektrischen Anschlüssen und
- - einem das Funktionselement-Netzwerk umgebenden dünnwandigen thermoplastischen Trägerfolienmantel.
- - A surface-related, centrally located functional element network of functional elements and interconnects with electrical connections and
- a thin-walled thermoplastic carrier film jacket surrounding the functional element network.
Im Funktionselement-Netzwerk sind als Komponenten zumindest Sensor(en), Aktor(en) und/oder Ansteuerelemente wie Operationsverstärker, Mikrokontroller vorhanden, die mittels zumindest als elektrisch leitfähige Strukturen ausgebildeten Leiterbahnen miteinander in Verbindung stehen.In the functional element network, at least one sensor (s), actuator (s) and / or control elements such as operational amplifiers, microcontrollers are present as components, which are connected to one another by means of interconnects formed as electrically conductive structures.
