Description
Faserverstärkter thermoplastischer Verbundwerkstoff Fiber reinforced thermoplastic composite
Die Erfindung betrifft einen faserverstärkten thermoplastischen Verbundwerkstoff, der eine Thermoplast-Matrix und eine Fasermatte oder ein Faservlies aus einem höher schmelzenden thermoplastischen Kunststoff enthält. Derartige Verbundwerkstoffe mit Polyester- oder Polyamid-Fasern sind in der DE-A 19831 124 beschrieben. Diese sogenannten TMT-Verbundwerkstoffe zeichnen sich gegenüber üblichen Verbundwerkstoffen aus glasmattenverstärkten Thermoplasten (GMT) durch eine hohe Bruchdehnung und eine bessere Duktilität aus, darüber hinaus haben sie ein geringeres Flächengewicht. Ihre mechanischen Eigenschaften, insbesondere die Festigkeit und Steifigkeit lassen jedoch zu wünschen übrig.The invention relates to a fiber-reinforced thermoplastic composite material which contains a thermoplastic matrix and a fiber mat or a non-woven fabric made of a higher melting thermoplastic material. Such composite materials with polyester or polyamide fibers are described in DE-A 19831 124. These so-called TMT composites are characterized by a high elongation at break and better ductility compared to conventional composites made of glass mat reinforced thermoplastics (GMT), and they also have a lower basis weight. However, their mechanical properties, especially their strength and rigidity, leave something to be desired.
Der Erfindung lag daher die Aufgabe zugrunde, die guten Eigenschaften von GMT- und TMT-Verbundwerkstoffen zu kombinieren.The object of the invention was therefore to combine the good properties of GMT and TMT composite materials.
Diese Aufgabe wird durch den erfindungsgemäßen Verbundwerkstoff gelöst. Dieser enthält mindestens eine Schicht A aus einer Thermoplast-Matrix und einer gegebenenfalls genadelten Fasermatte oder einem Faservlies aus einem thermoplastischen Polymeren, dessen Schmelzpunkt mindestens 20°C höher ist als der Schmelzpunkt des Matrix-Thermoplasten, und mindestens eine weitere Schicht B aus Fasergewebe oder Fasergelege.This object is achieved by the composite material according to the invention. This contains at least one layer A made of a thermoplastic matrix and an optionally needled fiber mat or a non-woven fabric made of a thermoplastic polymer, the melting point of which is at least 20 ° C. higher than the melting point of the matrix thermoplastic, and at least one further layer B made of fiber fabric or fiber fabric ,
Die Schicht A enthält eine Matrix aus einem Thermoplasten T1. Geeignete Thermoplasten T1 sind Polyolefine, Polyester und Polyamide. Bevorzugt ist Polypropylen. Darunter ist sowohl Homopolypropylen zu verstehen. als auch dessen Mischungen mit untergeordneten Mengen eines mit Maleinsäure oder mit Acrylsäure modifizierten Polypropylens oder mit anderen Polyolefinen, wie Polyethylen oder Polybutylen. Die Schicht A enthält außer der Thermoplast-Matrix vorzugsweise 10 bis 60, insbesondere 20 bis 40 Gew.-% eines Faservlieses oder einer gegebenenfalls genadelten Fasermatte aus einem Thermoplasten T2, dessen Schmelzpunkt mindestens 20°C, vorzugsweise mindestens 40°C höher ist als der Schmelzpunkt des Matrix-Thermoplasten T1. Als Thermoplasten T2 kommen in Frage lineare Polyester, Polyamide, Polyoxymethylen, Polycarbonat, Polyetherimide, Polysulfone Polyethersulfone und Polyphenylenoxid. Bevorzugt sind Polyethylenterephthalat-, Polyamid 6-, Polyamid 46- und Polyamid 66-Fasern. Es versteht sich von selbst, dass die Fasern der Faservliese bzw. Fasermatten ungerichtet sind. Die Faservliese können nach üblichen Krempel- oder Airlay-Verfahren hergestellt worden sein; die Matten können aus Schnittglas oder aus Endlos-Rovings bestehen und ebenfalls nach üblichen Verfahren hergestellt worden sein; sie sind vorzugsweise genadelt. Das Flächengewicht kann in weiten Grenzen zwischen 150 und 6000 g/m2 schwanken.Layer A contains a matrix made of a thermoplastic T1. Suitable thermoplastics T1 are polyolefins, polyesters and polyamides. Polypropylene is preferred. This includes both homopolypropylene. and also mixtures thereof with minor amounts of a polypropylene modified with maleic acid or with acrylic acid or with other polyolefins, such as polyethylene or polybutylene. In addition to the thermoplastic matrix, layer A preferably contains 10 to 60, in particular 20 to 40% by weight of a nonwoven fabric or an optionally needled fiber mat made of a thermoplastic T2, the melting point of which is at least 20 ° C., preferably at least 40 ° C. higher than that Melting point of the matrix thermoplastic T1. Linear thermoplastics, polyamides, polyoxymethylene, polycarbonate, polyetherimides, polysulfones, polyether sulfones and polyphenylene oxide are suitable as thermoplastics T2. Polyethylene terephthalate, polyamide 6, polyamide 46 and polyamide 66 fibers are preferred. It goes without saying that the fibers of the nonwovens or fiber mats are non-directional. The nonwovens can have been produced by conventional carding or airlay processes; the mats can consist of chopped glass or endless rovings and have also been produced by customary methods; they are preferably needled. The weight per unit area can vary between 150 and 6000 g / m 2 .
Die Schicht A kann grundsätzlich auf zwei verschiedene Arten hergestellt werden: Man kann fertige Faservliese oder Fasermatten mit einer Schmelze des Thermoplasten T1 kontinuierlich auf einer Doppelbandpresse oder mittels eines Kalanders imprägnieren. Vorzugsweise wird aber zunächst ein Mischvlies aus Fasern des höherschmelzenden Thermoplasten T2 mit Fasern des niedriger schmelzenden Thermoplasten T1 z.B. durch Krempeln hergestellt und dieses Mischvlies entweder durch Erhitzen über den Erweichungspunkt des Thermoplasten T1 und Ver- pressen konsolidiert oder das nicht konsolidierte Mischvlies direkt für die Herstellung des Verbundwerkstoffs eingesetzt, wobei dann die Fasern des Thermoplasten T1 aufschmelzen und die Matrix bilden. Die Schicht B ist ein Fasergelege oder ein Fasergewebe, das hochschmelzende Fasern, z. B. aus Glas, Kohlenstoff, Aramid, Polyethylenterephthalat oder Polyamid enthält. Auch. Hybridfasern aus diesen hochschmelzenden Fasern und Thermoplast- Fasern, vorzugsweise aus Polypropylen, sind geeignet. Durch diese Kombination der hochschmelzenden Fasern mit Fasern aus Thermoplasten, die mit dem der Matrix identisch sind, erhält man eine sehr gute Imprägnierung der hochschmelzenden Fasern und eine sehr gute Haftung der Schicht A mit der Schicht B.Layer A can basically be produced in two different ways: Finished nonwovens or fiber mats with a melt of the thermoplastic T1 can be impregnated continuously on a double belt press or by means of a calender. Preferably, however, a mixed fleece of fibers of the higher-melting thermoplastic T2 with fibers of the lower-melting thermoplastic T1 is produced, for example, by carding, and this mixed fleece is either consolidated by heating above the softening point of the thermoplastic T1 and pressing, or the non-consolidated mixed fleece is used directly for the production of the Composite material used, in which case the fibers of the thermoplastic T1 melt and form the matrix. Layer B is a fiber scrim or a fiber fabric that contains high-melting fibers, e.g. B. from glass, carbon, aramid, polyethylene terephthalate or polyamide. Also. Hybrid fibers made of these high-melting fibers and thermoplastic fibers, preferably made of polypropylene, are suitable. This combination of the high-melting fibers with fibers made of thermoplastics, which are identical to that of the matrix, results in a very good impregnation of the high-melting fibers and a very good adhesion of layer A with layer B.
In den Fasergeweben können die Fasern auch gemischt als Mischfasergewebe vorliegen, wobei der Schuss aus einem Fasertyp und die Kette aus einem anderen Fasertyp besteht, oder wobei die einzelnen Fasern Hybridfasern aus verschiedenartigen Fasertypen sind. Beispielsweise kann die Schicht A aus Polypropylen als Matrix- Thermoplast T1 und Polyethylenterephthalatfasern bestehen und die Schicht B aus einem Hybridfasergewebe Glas/Polypropylen (z. B. TWINTEX der Fa. Vetrotex).In the fiber fabrics, the fibers can also be mixed as a mixed fiber fabric, the weft consisting of one type of fiber and the warp made of another type of fiber, or the individual fibers being hybrid fibers made of different types of fibers. For example, layer A can consist of polypropylene as matrix thermoplastic T1 and polyethylene terephthalate fibers and layer B can be made of a hybrid fiber fabric glass / polypropylene (e.g. TWINTEX from Vetrotex).
Auch in den Fasergelegen können die Fasern aus Hybridfasern bestehen oder gemischt als Mischfasergelege vorliegen, in denen nebeneinander Fasern aus einem Fasertyp und Fasern aus einem anderen Fasertyp abgelegt sind. In den Fasergeweben bzw. -gelegen sind die einzelnen Fasern gerichtet. Das Flächengewicht der Fasergewebe bzw. -gelege kann in weiten Grenzen zwischen 50 und 1800 g/m2 schwanken. Die Schichten A sind vorzugsweise 0,2 bis 5 mm und die Schichten B vorzugsweise 0,1 bis 2 mm dick. Die bevorzugte Schichtenfolge ist BAB, es sind aber auch die Schichtenfolgen BA, BABAB, BABA und ABA möglich. Der erfindungsgemäße Verbundwerkstoff enthält vorzugsweise 10 bis 50 Gew.-% gerichtete Fasern als Gewebe oder Gelege, 10 bis 40 Gew.-% ungerichtete Fasern als Vlies oder Matte und 40 bis 80 Gew.-% des Thermoplasten T1 , wobei die Prozentzahlen sich auf 100 addieren.In the fiber fabrics as well, the fibers can consist of hybrid fibers or can be mixed as a mixed fiber fabric, in which fibers from one fiber type and fibers from another fiber type are stored next to one another. The individual fibers are directed in the fiber fabrics or lay. The weight per unit area of the fiber fabric or scrim can vary widely between 50 and 1800 g / m 2 . Layers A are preferably 0.2 to 5 mm and layers B are preferably 0.1 to 2 mm thick. The preferred layer sequence is BAB, but the layer sequences BA, BABAB, BABA and ABA are also possible. The composite material according to the invention preferably contains 10 to 50% by weight of directional fibers as a fabric or scrim, 10 to 40% by weight of non-directional fibers as a nonwoven or mat and 40 to 80% by weight of the thermoplastic T1, the percentages being 100 add.
Zur Herstellung des erfindungsgemäßen Verbundwerkstoffs wird entweder die Schicht A - wie oben beschrieben - separat hergestellt und anschließend mit dem Fasergewebe bzw. -gelege der Schicht B verpresst; oder es wird schon bei der Herstellung der Schicht A das Gewebe bzw. Gelege der Schicht B zugeführt und mitverpresst. Das Verpressen geschieht vorzugsweise kontinuierlich auf einer Doppelbandpresse oder mittels eines Kalanders, wobei es zweckmäßig sein kann, die Schichten vor dem Einführen in die Presswalzen vorzuerhitzen. Die Temperatur beim Verpressen der Schichten sollte zwischen dem Schmelzpunkt des Matrix- Thermoplasten T1 und dem Schmelzpunkt des Verstärkungsfaser-Thermoplasten T2 liegen. Im Fall von Polypropylen als Thermoplast T1 und Polyethylenterephthalat als Thermoplast T2 verpresst man vorzugsweise bei Temperaturen zwischen 180 und 220°C. Wenn in der Schicht B Polypropylenfasern entweder in einem Mischgewebe oder in Hybridfasern enthalten sind, schmelzen sie beim Verpressen auf und man erhält eine besonders gute Verbindung zwischen den Schichten.To produce the composite material according to the invention, either layer A - as described above - is produced separately and then pressed with the fiber fabric or scrim of layer B; or the fabric or scrim of layer B is fed in and co-pressed during the production of layer A. The pressing is preferably carried out continuously on a double belt press or by means of a calender, it being possible to preheat the layers before introducing them into the press rolls. The temperature during the pressing of the layers should be between the melting point of the matrix thermoplastic T1 and the melting point of the reinforcing fiber thermoplastic T2. In the case of polypropylene as thermoplastic T1 and polyethylene terephthalate as thermoplastic T2, it is preferably pressed at temperatures between 180 and 220 ° C. If polypropylene fibers are contained in layer B either in a blended fabric or in hybrid fibers, they melt when pressed and a particularly good bond between the layers is obtained.
Die erfindungsgemäßen Verbundwerkstoffe eignen sich zur Herstellung hochbelasteter Bauteile mit verbesserten Crasheigenschaften, die beim Aufprall nicht splittern, z. B. Automobilteile und Schallschluckelemente. BeispielThe composite materials according to the invention are suitable for the production of highly stressed components with improved crash properties which do not splinter upon impact, e.g. B. automotive parts and sound absorbing elements. example

An den Laminaten wurden folgende Eigenschaften bestimmt:A laminate 2 made of 23% by weight of a polyethylene terephthalate carded fleece, impregnated with 11% by weight of polypropylene (according to DE-A 198 31 124) with a thickness of 3.8 mm, served as a comparison.
