Description

Die Erfindung bezieht sich auf einen Multiaxialkomplex aus Multifilamentfäden gemäß dem Oberbegriff des Anspruches 1.The invention relates to a multi-axial complex of multifilament yarns according to the preamble of claim 1.

Weiterhin bezieht sich die Erfindung auf eine Vorrichtung zur Herstellung eines Multiaxialkomplexes aus Multifilamentfäden gemäß dem Oberbegriff des Anspruches 2.Furthermore, the invention relates to an apparatus for producing a Multiaxialkomplexes of multifilament yarns according to the preamble of claim 2.

Die Erfindung bezieht sich schließlich auf ein Verfahren zur Herstellung eines Multiaxialkomplexes aus Multifilamentfäden gemäß dem Oberbegriff des Anspruches 3.Finally, the invention relates to a method for producing a multi-axial complex of multifilament threads according to the preamble of claim 3.

Im Stand der Technik ist das Herstellen von Multifilamentkomplexen beispielsweise aus " Multi-Axiale Kettengewirke als textile Verstärkung in Faserverbundwerkstoffen", Melliand Textilberichte, International Textile Reports, DE, Melliand Textilberichte K.G. Heidelberg, Vol. 70, Nr. 2, Page(s) 109-112 XP000026288 ISSN: 0341-0781 bekannt. Vielfach bestehen derartige Multiaxialkomplexe oder Multiaxialgelege aus Multifilamenten aus Endlosfilamenten, die aus sehr biege- und bruchempfindlichen Fasern erstellt sind. Diese Multifilamentfäden aus Endlosfilamenten weisen eine gewisse Torsionstendenz auf, die dazu führt, daß diese Multifilamentfäden nach Ablage auf einer Unterlage nicht lagegesichert sind.For example, in the prior art, the production of multifilament complexes is " Multi-Axial Warp Yarns as Textile Reinforcement in Fiber Composites ", Melliand Textile Reports, International Textile Reports, DE, Melliand Textilberichte KG Heidelberg, Vol. 70, No. 2, Page (s) 109-112 XP000026288 ISSN: 0341-0781 known. In many cases, such Multiaxialkomplexe or Multiaxialgelege of multifilaments of continuous filaments, which are created from very bending and breakage-sensitive fibers. These multifilament filaments of endless filaments have a certain torsion tendency, which leads to these multifilament filaments not being secured in position after being deposited on a support.

Um eine solche Lagesicherung zu erreichen, war es im Stand der Technik üblich, die Multifilamentfäden der 0°-Lagen als oberste Schicht einzeln geführt auf dem Gelege anzuordnen, wobei dann beim Aufwickeln des fertigen Geleges auf einen Warenbaum eine Überbeanspruchung der Fasern dieser Multifilamentfäden eintrat. Bei einem eine Vielzahl von einzelnen Lagen, beispielsweise sechs oder sieben Lagen aufweisendem Multiaxialgelege, wurde deshalb bisher so vorgegangen, daß man Gelege mit beispielsweise zwei oder drei Lagen herstellt, in denen die 0°-Multifilamente in der ober-sten Lage angeordnet waren, dann eines dieser Gelege umdrehte, so daß dann zwei Gelege aufeinandergelegt waren, bei denen die 0°-Multifilamente in der Mitte angeordnet waren, also theoretisch in der sogenannten neutralen Zone. Diese bereits schon einmal vernähten Gelege mußten ein drittes Mal vernäht werden, nämlich wenn die beiden Gelege zusammengeführt wurden. Dies führte dazu, daß durch die Vielzahl von Nähvorgängen Schädigungen der Fasern der Multifilamente eintrat.In order to achieve such a position assurance, it was customary in the prior art to arrange the multifilament threads of the 0 ° layers individually as the topmost layer on the scrim, in which case an overloading of the fibers of these multifilament threads occurred during the winding of the finished scrim onto a fabric. In a multiaxial fabric having a plurality of individual layers, for example six or seven layers, it has hitherto been the case to produce layers of, for example, two or three layers in which the 0 ° multifilaments were arranged in the uppermost layer turned one of these clutches, so that then two clutches were superimposed, in which the 0 ° -multifilaments were arranged in the middle, that is theoretically in the so-called neutral zone. This already already sewn clutch had to be sewn a third time, namely, when the two clutches were brought together. As a result, damage to the fibers of the multifilaments occurred due to the large number of sewing operations.

Aus der DE 39 10 245 A1 ist ein Verfahren und eine Vorrichtung zur Herstellung eines Fadengitters bekanntgeworden. Um eine weitgehende Isotropie des Fadengitters zu erreichen, wird hier vorgeschlagen, oberhalb, unterhalb oder zwischen den einzelnen Scharen der bereits abgelegten und in Querrichtung sowie in Diagonalrichtung verlaufenden Fäden zusätzliche Fäden in Längsrichtung einzuführen. Die Zuführung der in Längsrichtung, d. h. also der 0°-Multifilamentfäden, unmittelbar vor der Vernähstelle ist dann möglich, wenn die 0°-Fäden zwischen die einzelnen Querfäden verlegt werden sollen. Diese an irgendeiner beliebigen Stelle zugeführten 0°-Fäden behalten aber ihre angestrebte Lage und gewünschte gleichmäßige Verteilung nicht bei, sondern verschieben sich, so daß unterschiedliche Dicken und damit unterschiedliche Festigkeiten in Querrichtung des Geleges gesehen zwangsläufig bedingt werden.From the DE 39 10 245 A1 a method and an apparatus for producing a thread grid has become known. In order to achieve a substantial isotropy of the thread grid, it is proposed here, above, below or between the individual Flock the already deposited and extending in the transverse direction and in the diagonal direction threads introduce additional threads in the longitudinal direction. The feeding of the longitudinal direction, ie the 0 ° -multifilament threads, immediately before the sewing is possible when the 0 ° threads are to be laid between the individual transverse threads. These 0 ° yarns supplied at any point, however, do not retain their desired position and desired uniform distribution, but shift so that different thicknesses and thus different strengths in the transverse direction of the fabric are inevitably caused.

Weiterhin wird hier vorgeschlagen, daß die abgelegten Fäden durch Kaschierung mittels Klebefolien bzw. Klebeflüssigkeiten untereinander verbunden werden. Eine solche zusätzliche Behandlung schränkt natürlich den Einsatzumfang des Fadengitters ein.Furthermore, it is proposed here that the deposited threads are connected by lamination by means of adhesive films or adhesive liquids with each other. Of course, such additional treatment limits the scope of use of the thread grid.

Aus der EP 1 112 400 B1 ist es bekanntgeworden, die Fädern der 0°-Lagen mittels lagesichernden bzw. verteilungssichernden Hilfsmitteln im Bereich vor der Nähwirkmaschine zu führen. Hier ist ein zusätzlicher Aufwand erforderlich. Zwar wird ein vorzügliches Gelege erreicht, aber der zusätzliche Aufwand erhöht die Produktionskosten.From the EP 1 112 400 B1 It has become known to guide the wheels of the 0 ° layers by means of position-securing or distribution-securing aids in the area in front of the stitchbonding machine. Here an additional effort is required. Although an excellent clutch is achieved, but the extra effort increases production costs.

In der DE 199 13 647 A1 wird ein Verfahren und eine Vorrichtung zum Herstellen von verwirkten bzw. vernähten Multiaxialgelegen aus mehreren Lagen beschrieben, wobei mindestens zwei in Arbeitsrichtung nacheinander angeordnete Wirkfonturen vorgesehen sind, welche die vor den Wirkfonturen abgelegten Fadenlagen im wesentlichen unmittelbar nach ihrem Ablegen fixieren. Hierdurch soll die Möglichkeit geschaffen werden, zwischen die Schußfadenlagen Stehfadenlagen einzuziehen, die unmittelbar nach Auflegen auf der Schußfadenlage durch die gesonderte Wirkfontur festgelegt wird. Durch die zusätzlichen Wirkfonturen zwischen Schußeintragssystem ist es möglich, eine hohe Flexibilität bezüglich der Anordnung der 0°-Fadenlagen zwischen den Schichten herkömmlicher Fadenorientierung zu erreichen.In the DE 199 13 647 A1 a method and an apparatus for producing sewn or sewn Multiaxialgelegen is described from a plurality of layers, wherein at least two successively arranged in the working direction Wirkfonturen are provided which the deposited before the Wirkfonturen thread layers substantially immediately after their removal fix. In this way, the possibility should be created to collect between the weft layers Stehfadenlagen, which is determined immediately after placing on the weft thread position by the separate Wirkfontur. Due to the additional Wirkfonturen between weft insertion system, it is possible to achieve a high degree of flexibility with respect to the arrangement of the 0 ° thread layers between the layers of conventional thread orientation.

Aus der DE 101 33 622 C1 ist ein Verfahren und eine Vorrichtung zum Aufbringen einer Faserschicht auf die Unterseite eines textilen Flächengebildes bekanntgeworden. Hier wird das Problem gelöst, eine vorzugsweise aus Faserschnitzeln bestehende Faserschicht an die Unterseite eines textilen Flächengebildes, insbesondere eines Fadengeleges, heranzuführen und diese Faserschicht in einem einzigen Arbeitsschritt gemeinsam mit dem Fadengelege und evtl. mit einer oberen Faserschicht zu verfestigen. Das Einziehen von 0°-Faden an beliebigen Stellen eines Multiaxialgeleges wird in dieser Literaturstelle weder beschrieben noch nahegelegt.From the DE 101 33 622 C1 For example, a method and apparatus for applying a fibrous layer to the underside of a fabric has become known. Here, the problem is solved, introduce a preferably made of fiber chips existing fiber layer to the underside of a fabric, in particular a thread scrim, and solidify this fiber layer in a single step together with the scrim and possibly with an upper fiber layer. The drawing in of 0 ° threads at any points of a multiaxial fabric is neither described nor suggested in this reference.

In der WO 98/10128 wird ein verbesserter kettengewirkter Strukturverbundstoff beschrieben, bei welchem in einem gesonderten Herstellungsverfahren stabilisierte Lagen der 0°-Fäden hergestellt werden, wobei diese vorgefertigten stabilisierten 0°-Fadenlagen an beliebiger Stelle zwischen den in unterschiedlichen Orientierungen geschichteten übrigen Multifilamentlagen angeordnet werden können. Durch die gesonderte Fertigung der 0°-Fadenlagen erfolgt durch mehrfache Vernähen derselben eine Beschädigung der einzelnen Filamente der Multifilamentfäden, eine Einschnürung der Filamente und damit eine Faserdesorientierung und eine größere oder kleinere Spreizung der Filamente, so daß die Fließmöglichkeit der Matrix geändert wird.In the WO 98/10128 there is described an improved warp knit structure composite in which, in a separate manufacturing process, stabilized layers of the 0 ° yarns are produced, these prefabricated stabilized 0 ° yarn layers being able to be placed anywhere between the remaining multifilament layers layered in different orientations. Due to the separate production of the 0 ° thread layers by multiple sewing same damage to the individual filaments of multifilament yarns, a constriction of the filaments and thus a Faserdesorientierung and a larger or smaller spread of the filaments, so that the flowability of the matrix is changed.

In der WO 91 05 896 wird ein flexibles Schleifwerkzeug beschrieben. Hier werden zwar die Multifilamentfäden der 0°-Lagen gespreizt, aber die Spreizung erfolgt durch die Art der Einbindung der 0°-Fäden mittels der Querfäden.In the WO 91 05 896 a flexible grinding tool is described. Although the multifilament threads of the 0 ° layers are spread apart here, the spreading takes place by the type of integration of the 0 ° threads by means of the transverse threads.

Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, einen Multiaxialkomplex aus Multifilamentfäden vorzuschlagen, das ohne zusätzliche chemische Mittel, wie Klebstoff usw. hergestellt werden kann und bei dem die Lagesicherung der Multifilamentfäden in der 0°-Lagen ohne großen maschinellen Aufwand erreichbar ist. Weiterhin bezieht sich die Erfindung auf eine Vorrichtung zur Herstellung eines solchen Komplexes und auf ein Verfahren zur Herstellung eines solchen Komplexes.The present invention is therefore based on the object to propose a Multiaxialkomplex of multifilament yarns, which can be prepared without additional chemical means, such as adhesive, etc. and in which the position assurance of the multifilament yarns in the 0 ° layers can be achieved without great mechanical complexity. Furthermore, the invention relates to an apparatus for producing such a complex and to a method for producing such a complex.

Gelöst wird die erste Aufgabe der Erfindung dadurch, daß die Multifilamentfäden der 0°-Lagen zwischen die in unterschiedlichen Orientierungen geschichteten übrigen Multifilamentlagen eingelegt sind und vor ihrer Auflage gespreizt und torsionsfrei zulaufen, und in dieser Form auf die vorherige Multifilamentlage aufgelegt sind.The first object of the invention is achieved in that the multifilament threads of the 0 ° layers are inserted between the other multifilament layers layered in different orientations and spread before their support and run without torsion, and are placed in this form on the previous multifilament layer.

Die Vorrichtung zur Herstellung eines solchen Geleges kennzeichnet sich durch in die Zuführung der Multifilamentfäden eingeschaltete Spannrollen, über die die Multifilamentfäden geführt werden.The device for producing such a fabric is characterized by tensioning rollers which are switched on in the feed of the multifilament yarns and over which the multifilament yarns are guided.

Das Verfahren zur Herstellung eines solchen Multiaxialkomplexes kennzeichnet dadurch, daß die Multifilamentfäden der 0°-Lage über Spannrollen vor ihrer Ablage auf der vorherigen Multifilamentlage geführt werden, die ein Spreizen der Multifilamentfäden bewirken und diese dadurch torsionsfrei machen.The process for producing such a multi-axial complex is characterized in that the multifilament threads of the 0 ° layer are guided over tension rollers before their deposition on the previous multifilament layer, which cause spreading of the multifilament threads and thereby make them torsionsfrei.

Überraschend wurde gefunden, daß beim Einsatz von torsionsfreien Multifilamentfäden der 0°-Lagen die Lagesicherung ausreichend ist und daß weiterhin die Maßnahme, die Multifilamentfäden torsionsfrei zu erhalten, in einfachster Weise dadurch erreichbar ist, daß die Fäden über Spannrollen geführt werden, die bei Bedarf ein Spreizen der Fäden bewirken und dadurch die Fäden flach ausbreiten, die sonst als Strang zugeführt werden.Surprisingly, it has been found that the use of torsion-free multifilament yarns of the 0 ° layers, the position assurance is sufficient and that continue the measure to obtain the multifilament yarn torsion, in the simplest way achievable that the threads are guided over idlers, the on demand Spreader the threads cause and thereby spread the threads flat, which are otherwise fed as a strand.
