Definitions

  • the invention relates to a 3D composite fabric.
  • the present invention relates to an optimized reinforcement fabric, of the multiply bonded type, which can be used for the production of composite material parts which are highly stressed in tension, compression or bending, and / or subjected to impacts. Among such parts, one can for example quote the landing struts.
  • Textile structures known as 1D or 2D are known depending on whether their fibers extend in a single direction or in two different directions. These structures, in general, do not make it possible to respond effectively to the aforementioned requests.
  • the so-called 3D structures comprising fibers extending in three distinct directions in space, are better able to respond to said stresses.
  • 4D, 5D, 9D, 11D ... with fibers extending in a larger number of distinct directions, but these structures are very complex and their production is difficult to automate.
  • the invention therefore relates more particularly to 3D textile structures.
  • 3D structures comprising a plurality of layers linked by connection points. These structures are known to have good linearity when bending the weft fibers, and offer the advantage of having reinforcements. However, this binding method does not give the piece produced from such a fabric good impact resistance.
  • Woven fabric is also known to be woven, the orthogonal 3D fabric (in which the ply-bonding fibers extend substantially orthogonally to the plies) being the one having the best linearity (i.e., a path with small bond angles or inflections) of the weft fibers and the warp fibers , and that resists compression well.
  • this fabric in order for this fabric to have a fiber volume fraction of interest, it must be compressed so that the orthogonal wires at the folds used to connect them acquire sharp inflections giving them a very undulating and therefore not very linear path, which does not does not contribute effectively to the transfer of effort.
  • non-orthogonal 3D fabrics are more interesting, they nevertheless have the drawback of having binding fibers having binding angles or inflections that are too great, that the reinforcement of the fabric is simple, type taffeta, satin or twill multiply, or that the frame is more elaborate, as the frame type 3X.
  • the fabric known as "2,5D”, described in the document FR 2,610,951 , particularly optimized, has low expansion and a high percentage of occupied area, but at the expense of low linearity (i.e. at least some of the fibers have significant inflections or binding angles).
  • the definition of this fabric gives it angular characteristics detrimental to impact resistance and limits reversible textile structures (obtained by rotating the frame at 90 degrees) to low density structures, unless a high number of plies added, which makes it difficult to automate.
  • the subject of the invention is a process for weaving an optimized 3D fabric having good resistance, in particular to impacts, while being easily deformable.
  • the relevant warp fibers A, B, C are represented in solid lines.
  • the warp fiber A passes over the first weft fiber 1 of the first column C1, passes under the second weft fiber 16 of the fifth column C5, passes over the first weft fiber 1 of the first column C1 of the following pattern.
  • the warp fiber B and the warp fiber C are parallel to the warp fiber A, but are shifted according to the fabric thickness of one weft fiber each time.
  • the basic pattern of the fabric reinforcement described here can be easily extended, both in the direction of the thickness of the fabric (hence in the direction of the columns), and in the lateral direction (so in the direction of levels).
