Die Erfindung stellt weiterhin eine Vorrichtung zur Durchführung dieses Verfahrens zur Verfügung, gemäß dem – jeder zulaufenden α-Materialbahn (2) eine Einrichtung zur Bildung eines permanenten Falzes (23; 32; 40) zugeordnet ist, – die parallel zur Translationsbewegung der Gelegebahn bewegbaren Transportmittel derart ausgebildet sind, dass – der Falz (23; 32; 40) in ihnen fixiert werden kann und – die Transportmittel sowohl parallel zur Bewegungsrichtung der entstehenden Gelegebahn translatorisch bewegbar als auch um ihre eigene Längsachse drehbar sind. Die Erfindung ist bei der Herstellung von multidirektionalen Prepregs anwendbar.The invention is based on the object. to provide a method and an apparatus for producing a multidirectional fabric web as well as a multidirectional fabric web for further processing into semi-finished products and components made of fiber composites. This object is achieved according to the invention by a method according to which a fold (23; 32; 40) is permanently introduced into the α-material web (2) in a predetermined width at least for the period of the jelly formation. The invention further provides an apparatus for carrying out this method, according to which - a means for forming a permanent fold (23; 32; 40) is associated with each inflowing α-material web (2), - the transport means movable in parallel to the translatory movement of the jelly-web are formed such that - the fold (23; 32; 40) can be fixed in them and - the transport means are both parallel to the direction of movement of the resulting tissue web translationally movable and rotatable about its own longitudinal axis. The invention is applicable to the production of multidirectional prepregs.
Description
Faserverbundwerkstoffe sind für den Leichtbau im Fahrzeug-, Maschinen- und Anlagenbau von großer Bedeutung. Zur rationellen Herstellung komplexer Strukturen und Bauteile aus Faserverbunden werden vorgefertigte faserverstärkte Halbzeuge in Form von Prepregs verwendet. Grundlage hierfür sind häufig uni- oder multidirektionale Gelegebahnen, die mit einem Matrixsystem imprägniert werden. Neben duroplastischen Harzsystemen kommen auch thermoplastische Kunststoffe als Matrixsysteme zur Einbettung unterschiedlicher Verstärkungsfasern, wie bspw. Glas-, Aramid- oder Kohlenstofffasern, zur Anwendung. Für die Produktion von Faserverbundbauteilen in Großserien werden derartige Prepregs zum Teil als mehrlagige, in den Einzelfaserlagen bereits vorgefertigte Halbzeuge benötigt.Fiber composite materials are of great importance for lightweight construction in vehicle, machine and plant construction. For the rational production of complex structures and components made of fiber composites, prefabricated fiber-reinforced semi-finished products in the form of prepregs are used. The basis for this is often unidirectional or multidirectional fabric webs which are impregnated with a matrix system. In addition to thermosetting resin systems, thermoplastics are also used as matrix systems for embedding different reinforcing fibers, such as, for example, glass, aramid or carbon fibers. For the production of fiber composite components in large series such prepregs are required in part as multi-layered, already prefabricated in the individual fiber layers semi-finished products.
Die nachfolgende Erfindung beschreibt ein Verfahren und eine Vorrichtung zur Herstellung einer in den Einzelfaserlagen vordefinierten, multidirektionalen Gelegebahn, die zu Herstellung eines Prepregs geeignet ist, bzw. in Form eines Prepregs sowie eine nach diesem Verfahren hergestellte Gelegebahn.The following invention describes a method and a device for producing a predefined in the individual fiber layers, multidirectional fabric web, which is suitable for producing a prepreg, or in the form of a prepreg and a fabricated web according to this method.
Verfahren zur Herstellung multidirektionaler Gelegestrukturen sind aus
In der
Das Führungs- und Transportsystem besteht aus einem in einem Gestellrahmen mit der Rotationsbewegung der Legeebene reversierenden Greifer, der die Bahnkanten des zu bildenden Geleges erfasst und über eine halbe Anlagendrehung mitführt. Die Bahnkanten werden im Moment des Erfassens durch das Führungselement gebildet. Anschließend übernimmt eine Transportvorrichtung die Materialbahn und bringt diese durch die Verfestigungsvorrichtung.The guide and transport system consists of a in a frame frame with the rotational movement of the laying plane reversing gripper, which detects the web edges of the gel to be formed and carries over half a turn of the system. The web edges are formed at the moment of detection by the guide element. Subsequently, a transport device takes over the material web and brings it through the solidification device.
Die Art der Bahnkantenbildung unmittelbar im Führungselement und die Anordnung eines getrennten Führungs- und Transportsystems für Gelegeablage und Verfestigung der Gelegebahn sind für die Herstellung der beschriebenen textilen Verstärkungsfaserstruktur vorteilhaft.The type of web edge formation directly in the guide element and the arrangement of a separate guide and transport system for gel deposit and solidification of the fabric web are advantageous for the production of the described textile reinforcing fiber structure.
Für die Bauteilherstellung aus Faserverbundwerkstoffen werden vorimprägnierte Faserstrukturen als Halbzeuge verwendet und zu mehrlagigen multidirektionalen Schichtaufbauten kombiniert.Prefabricated fiber structures are used as semifinished products for component manufacture from fiber composites and combined to multilayer multidirectional layer structures.
Bei der Verarbeitung vorimprägnierten, unidirektional faserverstärkten Ausgangsmaterials zu multidirektionalen Prepregs bestehen erweiterte Anforderungen an die Anlagentechnik zur Einbringung der Falze in die winklig zulaufende Materialbahn, verbunden mit der Anforderung, den entstehenden multidirektionalen Lagenaufbau verzugsfrei und in hoher Gelegequalität bis zur Verfestigung zu transportieren.When processing pre-impregnated, unidirectionally fiber-reinforced starting material to form multidirectional prepregs, there are additional requirements for the system technology for introducing the folds into the angled material web, combined with the requirement to transport the resultant multidirectional layer structure without warping and in high clutter quality until solidification.
