Definitions

  • the invention relates to a fabric according to the preamble of claim 1.
  • Textile structures of this type used for composite materials have a wide range of applications, primarily also in the aerospace industry. For example, they are used in engine chambers. In order to achieve the desired thickness, one usually goes the way of stacking or winding the individual textile layers over one another. The stacking of several fabrics is very complex and requires an additional sewing process to avoid slipping of individual layers, which leads to undesired, partial damage to the same when using high-performance fibers.
  • the object of the invention is to increase the proportion of the reinforcing textile structure, ie. H. the thickness to achieve without having to use the layer addition explained.
  • the desired initial thickness can be realized in one piece with simple means and without the time-consuming and expensive addition of layers.
  • the production can be set up on conventional weaving machines.
  • the fabric maintains a high level of suppleness (compared to a self-locking sewn or otherwise connected laminate).
  • the material accumulation in the third dimension is based on a rich, extremely tightly adjustable fold structure, a kind of pleated fabric.
  • the folds are adjustable in length and can be varied among themselves. Since they originate from a basic level, the fabric is also easy to control in production.
  • the procedure is advantageously such that the fabric consists of two warp systems, the second of which serves to form folds fastened at both ends to the first warp system in cross-section, the two warp systems being connected to one another by means of fixing shots at the fold ends.
  • the weft threads of the first warp system are the fixing wefts. These extend in the plane of the tensioned basic chain, which is practically used as a kind of guide rail for the folding of the folds.
  • the protuberances of the pleated fabric are each on the same side of the base fabric are arranged.
  • the double-legged, comb-like folding structure can turn out in such a way that the folds assume an overlapping structure like a roof shingle.
  • the warp threads for the fixing wefts are made of a thinner material than the warp threads for the pleated fabric.
  • the procedure is further such that the goods take-off roller is turned back to form the folds.
  • it is then rewound onto the warp beam by means of a winding gear motor.
  • the basis for achieving a textile structure of a fabric G of greater thickness is a fold-like structure.
  • at least two warp systems I, II are used.
  • One chain system I forms a basic chain.
  • the other warp system II forms a pleated chain.
  • the warp system I in conjunction with fixation shots 1 and 2, acts as a carrier for the folds F. It forms the real reason.
  • the shots in the fold-forming second warp system II have the reference number 3. They are the so-called fold shots.
  • the pleated chain (warp system II) is attached in the area of the fixing wefts 1 and 2 into the base fabric formed by the threads 4 of the basic chain (warp system I) and the fixing wefts 1 and 2.
  • shots are then only entered in the fold chain; whose threads are labeled 5. They alternate and cross each other.
  • the maximum fold height is determined by the distance between the reed 6 at the blade stop and the take-off roller 7 of the weaving machine and can be more than 10 cm. A goods deduction corresponding to the desired weft density takes place.
  • weft number weft density x fold height x 2
  • the stopping is effected.
  • the base warp threads 4 are blackened and the fold warp threads 5 are left white.
  • Both systems I, II have their own warp beam.
  • the folds F seen in cross section, rooting at both ends in the base fabric, all protrude on the same side of the fabric G in the exemplary embodiment. They are also of the same height. According to variant Fig. 3 they are perpendicular to the plane E-E of the fabric G.
  • the variant according to FIG. 4 shows a parallel orientation outside of said vertical. There they assume a roof shingle-like structure with an acute angle of inclination Alpha of, for example, 45 °.
  • fixation shots 1, 2 can be entered. Is z.
  • a dense, vertical fold level is desired (see FIG. 3)
  • only one or two fixing shots are entered, which may additionally consist of thinner material to reinforce the effect.
  • the embodiment shows the same thread thickness with respect to the wefts.
  • a certain angle of the folds F in the ferti structure can be reached, this angle is controlled by the distance between the folds in the base fabric.
  • folds can be alternately produced from different warp and weft materials.
  • Other mixed forms are also conceivable and should be selected according to the intended purpose.
  • different weft materials can be used by changing the weft in the individual folds F, so that a structure which is particularly suitable for ablation materials can be produced.
  • the basic warp (warp system I) is kept under tension (Fig. 10).
  • the goods take-off roller 7 is rotated back by the amount of the pleated fabric by means of an electronically controlled return device.
  • the base chain which is thereby loosened is wound back onto the warp beam 8 by means of a winding motor.
  • the chain is withdrawn according to the length of the pleats in the direction of the arrow y.
  • the weaving machine automatically starts up again.
  • the subsequent leaf stop pushes the first fixation weft of the new weave repeat into the second fixation weft of the previous weave repeat and thus throws the fabric, formed from the fold chain and the fold weft, to the fold.
  • the fixing section 2 contributes to the further fixing of the fold.
  • the warp deduction according to the weft density takes place in the direction of the arrow z.
  • the warp beam for the pleated chain (warp system II) is designated 9.
  • the shafts 10, like the reed 6 in front of the fabric edge 11, are only shown schematically.
  • high-performance fibers are processed in pure form or in a mixed form, such as glass fiber, aramid fiber, carbon fiber and processed into a composite material using a resin matrix.
  • the illustration in FIG. 1 may suffice as a product reference in this regard. These shows the wrinkled structure on an engine wall.
  • the enclosed chamber 12 is essentially cylindrical, but can also be converted into other shapes using the smoothness of the structure.
  • the direction of flow of the hot gases is indicated by arrow x.
  • the associated combustion chamber wall results from FIG. 1 and is designated by 13; it is made of steel.
  • a roll-in shape is also possible, the folds F pointing outward, for example.
