Definitions

  • the present invention relates to a woven structure for the production of a piece of composite material, as well as a method and a device for producing such a woven structure.
  • US-A-2,998,030 describes a weaving process, which implements means, such as a roller, to modify the speeds of movement of the different warp threads, in order to obtain a woven structure of curvilinear shape.
  • the object of the present invention is to improve such a process for weaving complex parts does not requiring little or no further treatment.
  • the structure woven fabric obtained can have a variable thickness, which can be freely select.
  • Figure 1 is a schematic top view of a device according to the invention.
  • Figure 2 is a schematic side view of a device according to the invention.
  • Figure 3 shows, in perspective, part of a device according to the invention.
  • Figure 4 schematically shows part of a structure woven according to the invention.
  • Figure 5 is a graphical representation allowing explain the determination of the profile of a cam according to the invention.
  • the weaving device 1 allows for a structure woven 2, of the tablecloth type, formed of FT weft threads and warp threads FC and intended for the production of a piece of composite material.
  • said device 1 further comprises a cam 5 to generate different movement speeds for at least some of said FC chain sons.
  • the set of elements 3A, 3B and 5 and of roller 8 specified below are integral and move together, and the cam 5 rotates regularly by an increment of rotation when the FC chain wires advance.
  • the woven structure 2 obtained by the device 1 has a non-rectangular shape, because although the longitudinal edges 7A and 7B according to the FC chain wires remain parallel, at least the lateral edge 6A is not perpendicular to said longitudinal edges 7A and 7B.
  • the lateral and longitudinal adjectives are defined by in relation to the weft and warp threads, and not in relation to the structure woven 2 final, the latter may have a longer length important according to the weft threads than according to the warp threads.
  • the profiled cam 5 is capable of rotate, at least partially around an axis X-X orthogonal to the direction D, and is arranged upstream of the means 3A and 3B, in the direction E of movement or advancement of the FC chain wires, near said means 3A and 3B.
  • the device 1 further comprises the roller 8 of axis L-L parallel to the X-X axis and arranged at a distance d upstream from the X-X axis, such that shown in Figure 5.
  • Said profiled cam 5 of generally planar shape has a profile adapted to the shape of the lateral edge 6A which it is desired to obtain, as specified below.
  • Said profile is defined by a transverse length h variable, perpendicular to said longitudinal axis X-X, as shown in Figure 5.
  • the length obtained by the product P.n can be determined differently if the displacement or advancement step P of the FC chain wires is not constant, namely by a simple summation of the lengths of the different steps.
  • the parameters h, d, r, ⁇ 1 and ⁇ 2 above are optimized to have the best possible distribution uniformity of the wires of weft FT between the lateral edges 6A and 6B of the woven structure 2.
  • r, h, ⁇ and d are parameters variables to choose, and I and ⁇ are unknowns, which we can calculate, as detailed below.
  • each FC chain wire is wound on a independent coil not shown so as to deliver different lengths of wire as specified and required by said device 1.
  • the device 1 according to the invention also makes it possible to modify the thickness of the woven structure 2, in particular in the case of realization of a multilayer type structure.
  • the device 1 according to the invention is simple to achieve and implement and it is inexpensive.
