Description

Faserverstärkter Kunststoff-Verbundwerkstoff Die Er£indun betrifft faserverstärkte Kunststoff-Verbundwerkstoffe. Fiber-reinforced plastic composite material which he £ indun concerns fiber-reinforced plastic composites.

Es sind Werkstoffe der genannten Art bekannt, bei denen die Verstärkungsfasern in einem massiven Kunststoffkörper angeordnet sind. Derartige Verbundwerkstoffe werden durch Tränken des~Veratirkungßmaterials mit flüssigen Kunststoffen und anschlie#endes Aushärten der Kunststoffe hergestellt. Die Dichte dieser bekannten Verbundwerkstoffe liegt im allgemeinen zwischen 1 und 2 g/cm3. Die mechanischen Eigenschaften sind im wesentlichen durch das verwendete Verstärkungsmaterial bestimmt.Materials of the type mentioned are known in which the reinforcing fibers are arranged in a solid plastic body. Such composite materials are made by soaking the processing material with liquid plastics and then Curing the plastics made. The density of these known composites is generally between 1 and 2 g / cm3. The mechanical properties are essentially determined by the reinforcement material used.

Es sind weiter als Werkstoffe geschäuste Kunststoffe, sogenannte Schaumstoffe, bekannt. Schaumstoffe sind in siah homogene, isotrope Werkstoffe mit gleichen Werkatoffeigenschaften in allen Beanspruchungsrichtungen.There are also plastic sheathed as materials, so-called foams, known. Foams are homogeneous, isotropic materials with the same material properties in all directions of use.

Solche Schaumstoffe, die auch mit pulverförmigen Füllstoffen bekannt sind, haben bei sehr niedrigem Raumgewicht auch sehr geringe Festigkeiten. Vor allem haben die elastischen Konstanten sehr niedrige Werte (E-Modul, G-Modul). Dies führt dazu, daß z. B. bei Sandwich-Konstruktionen mit Sohaumstoffkern die Tragfähigkeit durch das Schubversagen des Kerns begrenzt wird.Such foams, also known with powdered fillers are, with a very low density, also have very low strengths. Above all the elastic constants have very low values (modulus of elasticity, modulus of elasticity). this leads to to the fact that z. B. in sandwich constructions with a foam core, the load-bearing capacity is limited by the shear failure of the core.

Aufgabe der Erfindung ist es, Verbundwerkstoffe zu schaffen, die bei einem spezifischen Gewicht in Bereichen erheblich unter 1 g/em3 hohe Festigkeiten aufweisen.The object of the invention is to create composite materials that at a specific weight in areas significantly below 1 g / em3 high strengths exhibit.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die verstärkenden anorganischen oder organischen Fasern in einem aufgeschäumten Kunststoff eingebettet sind.This object is achieved according to the invention in that the reinforcing inorganic or organic fibers embedded in a foamed plastic are.

Die verstärkenden Fasern können dabei als Lang- oder Kurzfasern ungerichtet angeordnet sein. Die Werkstoffeigenschaften sind hierbei in allen Beanspruchungsrichtungen im wesentlichen gleich.The reinforcing fibers can be undirected as long or short fibers be arranged. The material properties are here in all directions of stress essentially the same.

Die Fasern können aber auch gerichtet angeordnet werden, wobei die Fasern etwa gleichmäßig verteilt oder aber in Faserbündeln angeordnet sein können. Die größte Festigkeit liegt hierbei in Längsrichtung der Fasern.However, the fibers can also be arranged in a directional manner, with the Fibers can be distributed approximately evenly or can be arranged in fiber bundles. The greatest strength lies in the longitudinal direction of the fibers.

Bei einer anderen Ausführungsform werden die gerichteten Fasern in zwei oder mehr Vorzugsrichtungen gekreuzt angeordnet, wobei zweckmäßig die Fasern in Bündeln liegen.In another embodiment, the directed fibers are in two or more preferred directions arranged crossed, with the fibers expediently lie in bundles.

The strength and elastic properties are of the proportion the Fiber reinforcement dependent and almost the same in all directions.

Bei der Ausführrngsform nach den Abbildungen 3 und 4 sind die Verstärkungsfasern mit einer Vorzugsrichtung angeordnet, wobei in Abb. 3 die Fasern als Einzelfasern oder Faden im wesentlichen gleichmäßig über den Querschnitt verteilt angeordnet sind, während bei der Ausfühungsform nach Abb. 4 die Verstärkungsfasern als Faserbündel angeordnet sind. Die Festigkeits- und elastischen Eigenschaften der Werkstoffe bzw. Formkörper nach den Abbildungen 3 und 4 erreichen in Richtung der Fasern ihre Höchstwerte.In the embodiment according to Figures 3 and 4, the reinforcing fibers are arranged with a preferred direction, with the fibers in Fig. 3 as individual fibers or thread arranged distributed essentially uniformly over the cross section are, while in the embodiment according to Fig. 4 the reinforcing fibers as fiber bundles are arranged. The strength and elastic properties of the materials or Moldings according to Figures 3 and 4 reach their maximum values in the direction of the fibers.

Bei der Ausführungsform nach den Abbildungen 5 - 7 sind die Fasern bzw. Faserbündel im Winkel zueinander gekreuzt in zwei Richtungen angeordnet, wobei Abb. 5 eine Anordnung mit verteilt liegenden Fasern mit einem Kreuzungswinkel von 90° zeigt, während bei der Ausführungsform nach Abb. 6 unter 900 gekreuzte Faserbündel zeigt.In the embodiment according to Figures 5-7, the fibers are or fiber bundles arranged at an angle to one another crossed in two directions, wherein Fig. 5 shows an arrangement with distributed fibers with a crossing angle of 90 ° shows, while in the embodiment according to Fig. 6 at 900 crossed fiber bundles shows.

Formkörper Höchstwerte der Festigkeits-und elastischen Eigenschaften in beiden Richtungen der Fasern.In the embodiments according to Figures 5 - 7, the materials or molded body maximum values of strength and elastic properties in both directions of the fibers.

In Werkstoffen bzw. Formkörpern mit gerichteter Anordnung der Verstärkungsfasern, insbesondere bei gebündelter Anordnung der Verstärkungsfasern, können zusätzlich noch regellos eingebraohte Fasern angeordnet werden, durch die eine weitere Verstärkung erzielt wird.In materials or moldings with a directed arrangement of the reinforcing fibers, in particular with a bundled arrangement of the reinforcing fibers, can additionally randomly baked fibers can be arranged, through which a further reinforcement is achieved.

Es ist dabei beispielsweise möglich, Jeweils zwischen swei lagen von gerichteten Faserbündeln eine Schicht regellos gerichteter Verstärkungsfasern anzuordnen. den verbindenden Schaumstoff können alle handelsüblichen schäumbaren Kunststoffe mit den entsprechenden Treibmitteln verwandet werden (z.3. Epoxydharze, Polyurethan, PVC usw.). Durch die Dosierung der Kunststoffkomponenten kann die Porigkeit des Schaumkörpers und damit das spezifische Gewicht des Werkstoffes beeinflußt werden.It is possible, for example, between swei layers of directed fiber bundles to arrange a layer of randomly directed reinforcing fibers. the connecting foam can be all commercially available foamable plastics be used with the appropriate propellants (e.g. epoxy resins, polyurethane, PVC etc.). By dosing the plastic components, the porosity of the Foam body and thus the specific weight of the material can be influenced.

Die Herstellung der Werkstoffe bzw. Formkörper nach den Abbildungen 1 und 2 kann beiapielsweise unter Verwendung von Epoxydharzen erfolgen. Der Faseranteil, z.B. Glasfaser, wird dem vermischten Harz/Härter-Ansatz beigegeben und eingerührt. Dann wird das Treibmittel zugegeben und vermiaht. Der fertige Ansatz wird in die Form gebracht, die offen oder geschlossen sein kann. Die Dichte des Werkstoffes kann bei Verwendung geschlossener Formen durch Anwendung von Druck beeinflußt werden. Bei der Herstellung von Leichtbauteilen in ßandwichbauweise kann der fertige Ansatz auch dinekt zwischen die äußeren Platten eingebracht und dann in Situ aufgeschäumt werden.The production of the materials or moldings according to the illustrations 1 and 2 can, for example, be carried out using epoxy resins. The fiber content, e.g. glass fiber, is added to the mixed resin / hardener mixture and stirred in. Then the propellant is added and mowed. The finished approach is in the Brought shape that can be open or closed. The density of the material can be influenced by the application of pressure when using closed molds. When manufacturing lightweight components in sandwich construction, the finished approach also dinekt placed between the outer panels and then foamed in situ will.

Bei Treibmittelzusätzen, die eine langsame aufschäumende Reaktion bewirken, kann das Treibmittel auch bereits dem Harz/Härter-Ansatz beigegeben werden, bevor der Faseranteil zugemischt wird.In the case of propellant additives, which have a slow foaming reaction effect, the propellant can also be added to the resin / hardener mixture, before the fiber content is added.

Die Fasern können auch in Form von Fasermatten oder Vliesen verwendet werden. Der Werkstoff wird dann durch Tränken der Matten oder Vliese mit dem Harz/Härter/Treibmittel-Ansatz erzeugt werden.The fibers can also be used in the form of fiber mats or fleeces will. The material is then through Soaking the mats or fleeces can be generated with the resin / hardener / blowing agent approach.
