Definitions

  • the present invention aims to provide a product which is compact and vacuum-free, and obtained by a simple process, from inexpensive raw materials.
  • the vegetable fibers can be sugarcane, jute, hemp, flax, cotton or kapok fibers. Preferably, however, these are coconut fibers.
  • the binder is a polyurethane adhesive.
  • Another advantage of these fibers is their resistance insects and other parasites that attack wood or bamboo.
  • the packages are placed in a mold, which, in the example chosen, has rectangular faces, the packages being arranged in successive layers, taking care to offset the end faces 6 from one layer to the other, to prevent formation lines of weakness, then pressure is exerted on the mold so as to obtain a homogeneous block, and the assembly is left in the mold until sufficient hardening so that the polymerization can be completed outside the mold.
  • the figure shows a block 1 roughly in the shape of a parallelepiped. It should however be observed that the process makes it possible to obtain blocks of various shapes, and even of very complex shapes. It is enough to provide the mold accordingly.
  • the packages located far from the walls of the mold have roughly the shape of a parallelepiped, while the packages intended to be placed near the walls may have a different shape .
  • the packages are arranged so that the fibers bypass the cores provided for this purpose in the mold, or even wrap around them. It is obviously the same if the block must include inserts, for example metallic. The flexibility of the fibers therefore allows a wide variety of manufacturing.

Claims (8)

  1. Bau- bzw. Konstruktionswerkstoff, das aus pflanzlichen Resten erhalten wurde, dadurch gekennzeichnet, daß es aus pflanzlichen Fasern gebildet ist, die mit einem Bindemittel imprägniert sind und die in Paketen (3) paralleler Fasern gruppiert sind,
    wobei jedes Paket die Form eines schiefen Parallelepipeds besitzt, das vier jeweils zwei parallel zueinander und parallel zu den Fasern verlaufende Seiten (4, 5), und zwei Stirn- oder Endflächen (6) aufweist, welche letztere parallel zueinander verlaufen und mit den Fasern einen Winkel von ungefähr zwischen 30° und 60° bilden,
    wobei die Pakete in übereinanderliegenden Schichten (2) angeordnet sind, deren jede mehrere Pakete aufweist von im wesentlichen der gleichen Größe und die mit ihren Stirnflächen in Kontakt miteinander stehen,
    wobei die Stirnflächen der Pakete einer Schicht bezüglich der Stirnflächen der Pakete einer benachbarten Schicht versetzt sind, und
    wobei die Pakete untereinander mittels des Bindemittels verbunden sind, mit dem die Fasern imprägniert sind, um einen Block zu bilden.
  2. Material nach Anspruch 1, dadurch gekennzeichnet, daß die Fasern Zuckerrohrfasern, Jutefasern, Hanffasern, Leinen- bzw. Flachsfasern, Baumwollfasern oder Kapokfasern sind.
  3. Material nach Anspruch 1, dadurch gekennzeichnet, daß die Fasern Kokosnußfasern sind.

  5. Verfahren zur Herstellung eines Materials nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß das Verfahren die folgenden Schritte aufweist:
    - Eintauchen der Fasern in das Bindemittel,
    - Anordnen der mit dem Bindemittel imprägnierten Fasern in einer Form, wobei die Fasern in Paketen (3) und Schichten (2) grupgiert sind,
    - Pressen der Fasern im Innern der Form bis zur mindestens teilweisen Polymerisation des Bindemittels,
    - gegebenenfalls Beenden der Polymerisation und Vornahme einer Trocknung außerhalb der Form.
  6. Verfahren zur Herstellung eines Materials nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß das Verfahren die folgenden Schritte aufweist:
    - Anordnen der nicht imprägnierten Fasern in einer Form, wobei die Fasern in Paketen und Schichten gruppiert sind,
    - Schließen der Form und Einführen des Bindemittels dorthinein, um die Fasern zu imprägnieren,
    - Pressen der Fasern im Innern der Form bis zur mindestens teilweisen Polymerisation des Bindemittels,
    - gegebenenfalls Beeden der Polymerisation und Vornahme einer Trocknung außerhalb der Form.
  7. Verfahren nach Anspruch 5 oder 6, dadurch gekennzeichnet, daß man zur Erleichterung der Anordnung der Fasern in der Form aufeinanderfolgende Pakete miteinander verbindet, und zwar dadurch, daß Fasern über ihre Verbindungestelle gelegt werden, oder mit einem Kleber.
  8. Verfahren nach einem der Ansprüche 5 bis 7, dadurch gekennzeichnet, daß das Bindemittel, mit dem man die Fasern imprägniert, ein Einkomponenten-Polyurethan-Kleber ist.
