Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren zur Wiederverwertung von Faserverbundabfällen aus ungetränkten Verstärkungs- und insbesondere Carbonfasern.The This invention relates to a method of recycling Fiber composite waste from unimpregnated reinforcing and in particular carbon fibers.
Anders
als Faserverbundabfälle aus flexiblen Verstärkungsfasern,
etwa Aramid- oder Kevlarfasern, die sich durch eine repetierende
Schlagkörpereinwirkung, z. B. mit Hilfe einer Hammermühle,
bis zu einer Faservereinzelung weitgehend zerstörungsfrei recyceln
lassen, stellt sich bei Carbonfaserverbundabfällen wegen
der großen Bruchempfindlichkeit des Fasermaterials das
Problem, den Faserverbund auf derart faserschonende Weise in Einzelfasern
zu zerlegen, dass deren Faserstruktur in dem entstehenden Fasergewirr
bruchstellenfrei erhalten bleibt. So werden nach der
Demgegenüber ist es Aufgabe der Erfindung, das Verfahren der eingangs genannten Art so auszubilden, dass sich die Faserverbundabfälle auf technologisch einfache Weise zu mechanisch hochwertigen Faserhalbzeugen mit einer vorbestimmten Faserlängenverteilung recyceln lassen.In contrast, It is an object of the invention, the method of the aforementioned Form such a way that the composite fiber waste on technological easy way to mechanically high-quality semi-finished fiber with a have recycled predetermined fiber length distribution.
Diese Aufgabe wird erfindungsgemäß durch das im Patentanspruch 1, 5 oder 9 gekennzeichnete Recyclingverfahren gelöst.These The object is achieved by the in the claim 1, 5 or 9 marked recycling process solved.
Bei den erfindungsgemäßen Recyclingverfahren nach den Ansprüchen 1 oder 5 lässt sich durch die Zuschnittsform und -größe der aus den Abfällen separierten Teilstücke unter Berücksichtigung der Faserorientierung von Vorneherein eine bestimmte Faserlängenverteilung innerhalb weiter Grenzen auswählen, die dann auch bei der anschließenden Faservereinzelung durch eine speziell auf die Bruchempfindlichkeit von Carbonfasern abgestimmte Schlagkörpereinwirkung unverändert erhalten bleibt, so dass das entstehende Fasergewirr von zufallsbedingten Faserlängenstreuungen freigehalten und demzufolge ein mechanisch vollwertiges Carbonfaserhalbzeug in Form eines Faservlieses nach der ersten oder eines Endlosfadens nach der zweiten Variante der Erfindung wiedergewonnen wird.at according to the recycling method according to the invention The claims 1 or 5 can be defined by the blank shape and size of the separated from the waste Pieces taking into account the fiber orientation from the outset a specific fiber length distribution within continue to select borders, which then also in the subsequent Fiber singulation by a special on the breaking sensitivity Carbon fiber tuned impactor action unchanged is maintained, so that the resulting fiber tangles of random Fiber length scattering kept free and therefore a mechanical full carbon fiber semi-finished in the form of a nonwoven fabric after the first or an endless thread according to the second variant of Invention is recovered.
Der erfindungswesentliche Aspekt, nämlich nicht die gesamten Faserverbundabfälle, sondern aus diesen nur separate Teilstücke mit einer unter Berücksichtigung der Faserorientierung definierten Zuschnittsform und -größe zu recyceln und diese unter Beibehalt der Faserlänge bis zur Faservereinzelung aufzuschließen, um daraus ein Faserhalbzeug mit einer vorbestimmten und nicht mehr sich zufällig ergebenden Faserlängenverteilung zu gewinnen, lässt sich, wie nach Anspruch 9 angegeben, natürlich nicht nur auf Carbonfaserverbundabfälle, sondern auch auf solche aus anderen ungetränkten Verstärkungsfasern anwenden.Of the essential to the invention, namely not the whole Composite fiber waste, but from these only separate cuts with one taking into account the fiber orientation defined blank shape and size to recycle and this while maintaining the fiber length to fiber singulation aufzuschlossen to make a semi-finished fiber with a predetermined and no longer random fiber length distribution can be obtained, as stated according to claim 9, of course, not just on carbon fiber composite waste, but also on those from other unimpregnated reinforcing fibers apply.
Die Weiterverarbeitung des Fasergewirrs zu einem Faservlies oder einem zu einer Endlosfaser versponnenen Faserflorband erfolgt zweckmäßigerweise im Wege einer Trockenvliesherstellung in einer Krempelanlage, und zwar in besonders bevorzugter Weise unter Erzeugung einer mechanisch günstigen Faservorzugsrichtung.The Further processing of the Faserverwirrs to a nonwoven fabric or a to a continuous fiber spun fiber ribbon is advantageously carried out by means of a dry nonwoven production in a carding machine, and Although in a particularly preferred manner to produce a mechanical favorable fiber orientation.
Aus Gründen einer verfahrenstechnisch einfachen Faservereinzelung mit geringem Fertigungsmittelaufwand werden die Teilstücke vorzugsweise in einer Hammermühle aufgeschlossen, welche beim Vereinzeln von Carbonfaserverbundabfällen auf eine nach Verweildauer und/oder Schlagstärke derart reduzierte Schlagkörperwirkung eingestellt wird, dass die Teilstücke zwar vollständig aufgelöst werden, ohne dass dadurch jedoch Einkürzungen oder sonstige Beschädigungen an den bruchempfindlichen Carbonfasern oder Carbonfilamenten entstehen.Out For reasons of simple process technology fiber separation with low production costs, the cuts preferably digested in a hammer mill, which when separating carbon fiber composite waste to one after Dwell time and / or impact strength such reduced impactor effect is set that the cuts though complete but without any shortcuts or other damage to the fracture-sensitive carbon fibers or carbon filaments are formed.
Bei Faserverbundabfällen mit einer uni- oder bidirektionalen Faserorientierung ist es im Rahmen der Erfindung sogar möglich, ein Fasergewirr und daraus ein Faserhalbzeug mit einer durchgehend konstanten Faserlänge zu erzeugen, indem die Abfälle in gleichseitig viereckige Teilstücke mit parallel zu den Faserrichtungen verlaufenden Seitenrändern zerschnitten werden.at Fiber composite waste with a uni- or bidirectional Fiber orientation it is even possible within the scope of the invention a fiber tangle and from it a semi-finished fiber with a constant throughout Fiber length produce by putting the waste in equilibrium quadrangular sections parallel to the grain directions running side edges are cut.
Eine weitere, besonders bevorzugte Maßnahme zur Beeinflussung des Faserlängenprofils in dem recycelten Faserhalbzeug besteht darin, dass die Zuschnittsgröße der Faserverbund-Teilstücke variabel vorgewählt wird.A Another, particularly preferred measure for influencing the fiber length profile in the recycled semifinished fiber product is that the blank size of the fiber composite sections is selected variable.
Die Erfindung wird nunmehr anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der Zeichnung näher erläutert, in deren einziger Figur ein Verfahrensablauf zum Recyceln von Faserverbundabfällen aus ungetränkten Carbonfasern mit einer sich unter 90° kreuzenden Faserorientierung in stark schematisierter Weise dargestellt ist.The invention will now be explained in more detail with reference to a preferred embodiment in conjunction with the drawing, in the sole figure of a process sequence for recycling Faserver bund waste of unimpregnated carbon fibers is shown with a crossing at 90 ° fiber orientation in a highly schematic manner.

Mit dem beschreibenen Verfahren ist es möglich, die Faserlängenanteile in den recycelten Faservliesen oder Endlosfäden durch entsprechende Wahl der Zuschnittsform und -größe der aus den Abfällen unter Berücksichtigung der Faserorientierung ausgeschnittenen Teilstücke gezielt zu beeinflussen und so aus den Faserabfällen wieder mechanisch hochwertige Halbzeuge zu gewinnen und diese erneut der ursprünglichen Prozesskette zuzuführen.With the described method, it is possible, the fiber length proportions in the recycled fiber webs or continuous filaments by appropriate choice the blank shape and size of the waste cut out in consideration of fiber orientation Targeted to influence cuts and so from the fiber waste again to win mechanically high-quality semi-finished products and this again to the original process chain.
