BeschreibungDescription
Die Erfindung betrifft einen Werkstoffverbund, bestehend aus einem naturfasergefüllten Thermoplasten in Verbindung mit metallischen Einlegeteilen sowie ein Verfahren zu Herstellung von Bauteilen aus diesem Werkstoffverbund.The invention relates to a material composite consisting of a natural fiber-filled thermoplastic in combination with metallic inserts and a method for producing components from this material composite.
Es ist bekannt, Kunststoffformkörper mit hohem Faseranteil herzustellen. Mittels Extrusion-Press- oder Spritzgießverfahren werden dabei Bauteile aus Polymeren als Matrix in Verbindung mit Fasern als Füllstoff oder zur Verstärkung gefertigt. Für hochfeste Bauteile werden im wesentlichen Glas- oder Kohlefasern eingesetzt. Im Bereich der hochgefüllten naturfaserverstärkten Kunststoffe sind Bauteile für den Automobilinnenraum bekannt, wobei diese häufig aus Duromeren und Naturfasern im Pressverfahren hergestellt werden. Auch der Einsatz von Naturfasern wie Holzfasern in Verbindung mit Thermoplasten im Extrusionsverfahren bei der Fertigung von Platten und Halbzeugen ist Stand der Technik.It is known to produce plastic moldings with a high fiber content. Using extrusion-pressing or injection molding processes, components are manufactured from polymers as a matrix in combination with fibers as fillers or for reinforcement. Glass or carbon fibers are mainly used for high-strength components. In the field of highly filled natural fiber-reinforced plastics, components for automotive interiors are known, although these are often made from duromers and natural fibers using a pressing process. The use of natural fibers such as wood fibers in combination with thermoplastics in the extrusion process in the manufacture of panels and semi-finished products is also state of the art.
Zur Kombination von Bauteilen mit Folien, Textilien oder Verstärkungsfasern sind Verfahren wie Hinterspritzen oder Hinterpressen der Deckschichten bekannt. Häufig werden für hochfeste Bauteile beim Pressprozess Glasfasern oder Glasfaser-Matten eingebracht. Die Haftung zwischen Bauteil und Deckschicht beruht hier auf einer Benetzbarkeit des Deckschichtwerkstoffes. Andere Verfahren zeichnen sich durch Deckschichten aus die auf dem gleichen Material bestehen wie das eigentliche Bauteil, z.B. das Hinterspritzen oder Hinterpressen von Polyolefinfolien mit Polyolefinen. Diese Art der Beschichtungen dienen jedoch in erster Linie als Dekor und nicht zur Verstärkung des Bauteils.Processes such as back-injection or back-pressing of the cover layers are known for combining components with films, textiles or reinforcing fibers. Glass fibers or glass fiber mats are often introduced during the pressing process for high-strength components. The adhesion between the component and the cover layer is based on the wettability of the cover layer material. Other processes are characterized by cover layers that consist of the same material as the actual component, e.g. back-injection or back-pressing of polyolefin films with polyolefins. However, these types of coatings are primarily used as decoration and not to reinforce the component.
Verstärkungen mit Fasern oder Fasermatten können nur reine Zugbelastungen in Faserrichtung aufnehmen. Die Dimensionsstabilität der Bauteile ist von der Faserorientierung abhängig. Kunststoffe mit hohem Füllstoffanteil weisen zwar eine hohe Festigkeit auf, sind aber relativ spröde. Für die Montage der Bauteile oder Anbindung weiterer Komponenten mit Schraub- oder Nietverbindungen sind zusätzliche Arbeitsschritte notwendig und ggf. mit einer Schwächung des Bauteiles an den Verbindungsstellen zu rechnen. Naturfasergefüllte Thermoplaste in Verbindung mit metallischen Einlegern in Form von Armierungen wie Streckmetalle oder Lochbleche sind nicht bekannt.Reinforcements with fibers or fiber mats can only absorb pure tensile loads in the direction of the fibers. The dimensional stability of the components depends on the fiber orientation. Plastics with a high filler content are very strong, but are relatively brittle. Additional work steps are necessary for assembling the components or connecting other components with screw or rivet connections, and a weakening of the component at the connection points may be expected. Thermoplastics filled with natural fibers in combination with metallic inserts in the form of reinforcements such as expanded metal or perforated sheet metal are not known.
Der Erfindung liegt die Aufgabe zugrunde, Bauteile die aus thermoplastischen Kunststoffen in Verbindung mit einem Naturfaseranteil von 60 % bis 98 % bestehen herzustellen, die sich durch einen gute Festigkeitseigenschaften auszeichnen und eine einfache Anbindung weiterer Komponenten erlaubten.The invention is based on the object of producing components which consist of thermoplastics in combination with a natural fibre content of 60% to 98%, which are characterised by good strength properties and allow easy connection of further components.
Dies wird dadurch gelöst, dass naturfasergefüllte Thermoplaste, wobei vorzugsweise Holzfasern als Füllstoff und Polypropylen als Matrix eingesetzt werden mit metallischen Einlegeteilen versehen werden, wobei diese mit dem Thermoplasten eine formschlüssige Verbindung eingehen.This is solved by providing natural fiber-filled thermoplastics, preferably using wood fibers as filler and polypropylene as matrix, with metallic inserts, which form a positive connection with the thermoplastic.
Die Einlegeteile erfüllen zwei Aufgaben. Zum einen erfüllen die Einlegeteile die bekannten Verstärkungsfunktionen wie Erhöhung der Zug- und Biege- und Torsionsfestigkeit. Zum andern werden über die Einlegeteile Möglichkeiten zur Anbindung weiterer Elemente über Schraub-, Niet- oder Schweißverbindungen gegeben. Ferner bewirken die metallischen Einlegeteile auch bei Bruch der Kunststoffmatrix einen Zusammenhalt des Bauteiles über die Metalleinleger und eine Splitterwirkung wird vermieden.The inserts fulfill two tasks. Firstly, the inserts fulfill the well-known reinforcement functions such as increasing the tensile, bending and torsional strength. Secondly, the inserts provide options for connecting other elements using screw, rivet or weld connections. Furthermore, the metal inserts ensure that the component is held together via the metal inserts even if the plastic matrix breaks, and splintering is avoided.
Die Verarbeitung der Materialien und Formgebung erfolgt über Extrusions-, Spritzgussverfahren oder Pressverfahren. Im Extrusionsverfahren erfolgt die Formgebung durch ein Extrusionswerkzeug zur Halbzeugherstellung und die Zufuhr der metallischenThe processing of the materials and shaping takes place via extrusion, injection molding or pressing processes. In the extrusion process, the shaping takes place using an extrusion tool for semi-finished product production and the supply of the metallic

Einleger im Düsenbereich. Hierbei wird ein Thermoplast-Granulat oder -pulver mit 60-98 Gewichtsprozent Lignocellulosefasern und gegebenenfalls Haftvermittlern gemischt. Über eine Extrusionswerkzeug werden Halbzeuge gefertigt, deren Querschnitt und Oberflächenstruktur durch die Werkzeuggeometrie des Extrusionswerkzeuges vorgegeben wird.Insert in the nozzle area. Here, a thermoplastic granulate or powder is mixed with 60-98 percent by weight of lignocellulose fibers and, if necessary, adhesion promoters. Semi-finished products are manufactured using an extrusion tool, the cross-section and surface structure of which are determined by the geometry of the extrusion tool.
Bei der Herstellung von Bauteilen im Spritzgießprozess erfolgt zunächst ein manuelles Vormischen der Ausgangsstoffe, die Herstellung von Pellets oder die Compoundierung im Extrusionsprozess. Eine Variante ist auch das direkte Zudosieren der Ausgangsstoffe während des Spritzgießprozesses. Die metallischen Einlegeteile werden ins Spritzgießwerkzeug eingelegt und um-, bzw. hinterspritzt.When manufacturing components using the injection molding process, the starting materials are first manually premixed, then pellets are produced or compounded using the extrusion process. Another option is to directly add the starting materials during the injection molding process. The metal inserts are placed in the injection molding tool and then molded around or behind the mold.
Die Verarbeitung im Pressprozess sieht ein Mischen wie im Extrusionsprozess oder eine Zugabe der Ausgangsmaterialien in ein einfach- oder Mehrfachwerkzeug vor und das um- bzw. hinterpressen der metallischen Einlegeteile.The processing in the pressing process involves mixing as in the extrusion process or adding the starting materials to a single or multiple tool and pressing the metal inserts around or behind them.
Vorteilhaft bei diesem Werkstoffverbund und den Verfahren zu dessen Herstellung ist in erster Linie die Möglichkeit Bauteile mit hohem Anteil an Naturfasern vorzugsweise Holzfasern mit herzustellen, die wesentlich preisgünstiger als reine Holzbauteile oder auch reine Kunststoffbauteile sind. Über die Armierung mit metallischen Einlegern wird eine zusätzliche Festigkeitssteigerung, erreicht, die vor allem die Biegefestigkeit erhöht und Splitterneigung bei Bruch wird reduziert. Die Formgebung der Bauteile ist über die Werkzeuggestaltung nahezu beliebig wählbar, womit im Vergleich zu massiven Holzformteilen eine rationelle Fertigung von Bauteilen ohne Nachbearbeitung ermöglicht wird. Ferner sind Möglichkeiten zur Anbindung weiterer Elemente über Schraub-, Niet- oder Schweißverbindungen an die metallischen Einleger gegeben, was beispielsweise im Möbelbau von Bedeutung sein kann. Die hochgefüllten Kunststoffe zeichnen sich durch ähnliche Eigenschaften wie Holz aus und weisen eine hohe Festigkeit auf und sind vor allem als preiswerte Alternative zu Massivholzteilen zu sehen.The main advantage of this material composite and the process for its production is the ability to manufacture components with a high proportion of natural fibers, preferably wood fibers, which are significantly cheaper than pure wood components or pure plastic components. Reinforcing with metal inserts provides an additional increase in strength, which above all increases the bending strength and reduces the tendency to splinter in the event of breakage. The shape of the components can be selected almost arbitrarily using the tool design, which, in comparison to solid wood molded parts, enables components to be produced efficiently without any post-processing. There are also options for connecting other elements to the metal inserts using screw, rivet or weld connections, which can be important in furniture construction, for example. The highly filled plastics are characterized by properties similar to those of wood and are very strong, and are primarily seen as an inexpensive alternative to solid wood parts.

AusführungsbeispielExample
Einem Gemisch (1) aus Polypropylen-Granulat und 60-98 Gewichtsprozent Holzfasern als Füllstoff wird einer Extrusionseinrichtung (2) zugeführt. Am Düsenausgang (3) des Extruders (2) wird die Armierung (4) beispielsweise in Form eines gelochten Metallbandes zugeführt. Durch die Düsengeometrie wird letztlich die Querschnittsgeometrie extrudierten Profiles (5) bestehend aus holzgefülltem Polypropylen und der Metallarmierung festgelegt.A mixture (1) of polypropylene granulate and 60-98 percent by weight of wood fibers as a filler is fed into an extrusion device (2). The reinforcement (4) is fed into the nozzle outlet (3) of the extruder (2), for example in the form of a perforated metal strip. The nozzle geometry ultimately determines the cross-sectional geometry of the extruded profile (5) consisting of wood-filled polypropylene and the metal reinforcement.
