Definitions

  • the present invention relates to an improvement made to the textile reinforcements used for the production of various complexes, such as laminated articles.
  • nonwovens of fibers unidirectional sheets, that is to say in which the structural filaments are arranged in the same direction, fabrics, bidirectional sheets, such as for example warp and weft fabrics, or even combinations of such materials.
  • the present invention relates to an improvement made to bidirectional structures of the warp and weft fabric type.
  • Warp and weft fabrics have been proposed for a very long time as reinforcements for reinforcing laminated articles. They have the advantages of being able to be manufactured easily, of obtaining good mechanical characteristics both in the long direction and in the transverse direction. On the other hand, for certain applications, they have certain drawbacks which result from the fact that the warp and weft threads undulate with respect to each other as a result of weaving, while we frequently seek to have reinforcements in which the filaments are arranged as straight and as flat as possible in the same longitudinal direction and this, to form a uniform sheet or strip.
  • Such a product is obtained by the implementation of a new operating process which is also the subject of the present invention, a process which consists in producing a warp and weft fabric from continuous filaments (glass, carbon) having the form of wicks, then subjecting the fabric thus formed to a needling operation carried out under conditions such that the threads are spread from one of the directions of the fabric without damaging the filaments which compose them and, on the other apart, that simultaneously breaking part of the filaments in the other direction of said fabric.
  • needles are used whose barbs are not disposed over the entire periphery of the needle, but are oriented parallel to one of the directions of the fabric (warp or weft). These barbs can be arranged either according to a generator of each needle, or symmetrically on either side of the barrel of the needle, for example at the rear and at the front of the barrel if we consider the direction of advancement of the starting fabric inside the needling machine.
  • the invention therefore relates to an improvement made to the warp and weft fabrics used for the reinforcement of laminated articles, said fabrics appearing, before treatment in accordance with the invention and in a well known manner.
  • the fabric in the form of a sheet made up of warp threads (1a, 1b, 1c) crisscrossed with weft threads (2a, 2b, 2c), and arranged orthogonally to each other.
  • the fabric is made according to a conventional weave called "canvas" weave, but it is obvious that other types of weave could also be used.
  • the warp threads designated by the general reference (1) consist of wicks of parallel filaments and are in the form of bundles arranged side by side, the weft threads designated by the general reference (2) also being made up of bundles of parallel filaments (wicks).
  • the weft and warp wicks can be either of the same kind or of a different nature (for example wicks of glass, carbon, synthetic yarns, etc.).
  • the starting fabric is subjected to a needling action by means of an assembly (3), assembly which is constituted by a conventional needle needling machine, adapted, in accordance with the process according to the invention , so that the needles when they act on the fabric, on the one hand cause the separation of either warp threads or weft threads without damaging the filaments and, on the other hand, have an action on the other series of threads (weft threads for example), so as to cause the filaments to rupture and cause disorientation so that these filaments are implanted in the thickness direction of the fabric.
  • assembly (3) assembly which is constituted by a conventional needle needling machine, adapted, in accordance with the process according to the invention , so that the needles when they act on the fabric, on the one hand cause the separation of either warp threads or weft threads without damaging the filaments and, on the other hand, have an action on the other series of threads (weft threads for example), so as to cause the filaments to rupture and cause disorientation so that these
  • needles (4) in which the barbs (5) are not disposed over the entire periphery of the barrel, but are oriented parallel to the wicks either of chain or of frame.
  • the barbs (5) are presented parallel to the warp threads (see Figures 2 and 3).
  • the barbs (5) of the needles can be arranged symmetrically on either side of the barrel of the needle or, possibly on one side, for example behind the barrel if we consider the direction of advance fabric through the needling machine (3).
  • Such a material is particularly advantageous for producing laminated articles in which it is desired to have resistance characteristics in a determined direction.
  • the material according to the invention has, surprisingly, the characteristic of facilitating the impregnation operation with the resin.

Claims (5)

  1. Textilarmierung, die zur Herstellung von verschiedenen Komplexen benutzbar ist und in der Form einer Lage vorliegt, bei der die Mehrzahl der Elementarfäden entlang einer einzigen Richtung angeordnet sind, dadurch gekennzeichnet, daß
    - sie durch ein Gewebe gebildet ist, bei dem die Fäden der Kette und des Schusses in der Form von parallelen Fadenbündeln vorliegen,
    - der Zusammenhalt der Elementarfäden durch eine faserige Struktur (2a, 2b, 2c) sichergestellt ist, die nicht nur mit den unidirektionalen Fäden nach Art eines Gewebes gekreuzt ist, sondern überdies Fasern aufweist, die sich zum Teil rechtwinklig zwischen zwei aufeinanderfolgenden Serien der parallelen Fäden (1a, 1b, 1c) erstrecken und die durch geknickte Fäden, die in die Richtung der Gewebedicke eingebracht sind, gebildet sind.
  2. Verfahren zum Erhalt einer Armierung nach Anspruch 1, das daraus besteht, daß ausgehend von kontinuierlichen Fäden (1a, 1b, 1c..., 2a, 2b, 2c...), die in der Form von groben Vorgespinsten vorliegen, dadurch gekennzeichnet, daß man das so gebildete Gewebe anschließend einer Nadelungsbearbeitung unter solchen Bedingungen unterwirft, daß man die Fäden der einen Vorzugsrichtung (1a, 1b, 1c) des Gewebes voneinander trennt, ohne die sie bildenden Fäden zu zerstören, und daß man andererseits gleichzeitig einen Teil der Fäden der anderen Vorzugsrichtung (2a, 2b, 2c) des Gewebes knickt.
  3. Verfahren nach Anspruch 2, dadurch gekennzeichnet, daß man die während des Nadelungsvorganges benutzten Nadeln Widerhaken aufweisen, die nicht um den gesamten Randbereich der Nadel angeordnet sind, sondern die parallel zu einer der Vorzugsrichtungen des Gewebes (Kette oder Schuß) ausgerichtet sind.
  4. Verfahren nach Anspruch 3, dadurch gekennzeichnet, daß die Widerhaken (5) der Nadeln (4) symmetrisch beiderseits des Schaftes der Nadel (4) angeordnet sind.
  5. Verfahren nach Anspruch 3, dadurch gekennzeichnet, daß die Widerhaken (5) der Nadeln (4) auf einer Seite des Schaftes der Nadel (4) und vorzugsweise auf der Rückseite dieses Schaftes, wenn man die Laufrichtung im Inneren der Nadelungseinheit (3) betrachtet, angeordnet sind.
