Definitions

  • the present invention relates to a process for the production of fiber layers, as well as fiber fabrics and their use.
  • Fiber fabrics are inexpensive to produce compared to fabrics. At the same time, however, fiber fabrics have only a very poor cohesion, which makes processing of fiber layers, especially on an industrial scale, much more difficult.
  • fiber layers can be glued, be linked or forfeited by hot-melt binding threads or joined together by needling.
  • a method for producing a composite based on a fiber structure using a chemical binder is described, for example, in the patent FR 1 394 271.
  • a compound of fiber layers by needling leads only to comparatively low loadable fiber layers, while a compound by gluing or using hot melt binding threads carries the risk that at higher temperatures cohesion of the fiber fabric in sufficient strength is no longer given, as the adhesive or melt or decompose the hot-melt binding yarns.
  • residues may remain on the fiber layer.
  • the object of the present invention is therefore to produce a fabric which avoids local accumulations of fibers and improves the final component properties.
  • filament yarn of carbon, glass, ceramic or polymer eg aramid
  • the scrim according to the invention should consist of laid fiber material in the form of fiber bundles or multifilaments and the binding thread (eg knitting thread) required for joining the individual device layers.
  • This object is achieved by a mechanical consolidation of the fiber bundle, wherein the fiber structure of the submitted fiber is included and used to stabilize the fiber structure.
  • a device for the mechanical consolidation of fiber layers is shown in FIG.
  • the number of submitted filament yarns according to the invention depends on the basis weight to be achieved in the device layer.
  • the sizing content and the fiber surface properties can already be adapted during the fiber production for the purpose of adjustment.
  • the invention therefore relates to a method for producing a fiber layer with a longitudinal direction, wherein the method is based on the fact that parallel guided fiber bundles of equal or different fiber fineness spreads, merged overlapping and thereby mechanically consolidated, wherein at least a sliver is obtained as a Einhechtungslage with a defined width without the application of an additional fixative and / or additional mechanical or physical fixation methods.
  • Different titers of the fiber particularly preferably allow different spread widths of the individual fiber bundles. The higher the titer, the greater the possible spread width.
  • Adhesion forces are interaction forces between molecules of different substances between several phases. Adhesion forces cause the stiction, the adhesion of different substances and the wetting.
  • filament yarns of the present invention are spread parallel to each other in accordance with the required number, wherein the filament yarns can also partially overlap.
  • Filament yarns are endless filaments, usually of synthetic, natural or inorganic raw materials, so-called filaments spun from spinnerets.
  • a fiber bundle consists of slivers, each representing thick, linear formations of many fibers, z. B. preferably 5000 to 400,000 fibers and more preferably 50,000 fibers in the band cross-section.
  • the spreading according to the invention is carried out in several, preferably two to five planes via round and / or angular deflection rollers, which are fixedly mounted.
  • the separately spread levels are then merged overlapping.
  • the course of the spreading is preferably carried out via heated deflection points and various devices that can act on the material with temperature, pressure and humidity.
  • individual deflection points are integrated with air or suction nozzles in the process.
  • an optional overlap of the fibers of at least 1% to a maximum of 100% is possible, preferably from 5% to 50% and particularly preferably from 10% to 20%.
  • a fiber layer is more than 70% by weight, more preferably more than 99% by weight, of fibers selected from the group consisting of carbon fibers, precursor fibers of carbon fibers, ceramic fibers, glass fibers, polymer fibers (e.g. Aramid) and mixtures thereof, based on the total weight of the respective fiber layer.
  • fibers selected from the group consisting of carbon fibers, precursor fibers of carbon fibers, ceramic fibers, glass fibers, polymer fibers (e.g. Aramid) and mixtures thereof, based on the total weight of the respective fiber layer.
  • At least one fiber layer has a weight per unit area in a range of 50 g / m 2 to 800 g / m 2 , particularly preferred is a range of 100 g / m 2 to 300 g / m 2 , with this Particularly preferred range, for example, biaxial scrim with 200 g / m 2 to 600 g / m 2 produce.
  • At least one fiber bundle has a number of filaments in a range of 0.5 K (500 filaments) up to 500 K (500000 filaments), preferably in a range of 1 K (1000 filaments) up to 400 K (400000 filaments) , more preferably in a range of 12 K (12000 filaments) to 60 K (60,000 filaments).
  • the invention further provides a fiber fabric consisting of at least one or more device layers having a different orientation, obtainable by providing an arrangement of at least one fiber layer having a longitudinal direction which has partially or completely superimposed device layers, without an additional fixative and / or additional mechanical or physical fixing methods are required and wherein at least one fiber layer to more than 70 wt .-%, preferably more than 85 wt .-%, more preferably more than 98 wt .-% consists of fibers which are selected from the group consisting of carbon fibers, precursor fibers of carbon fibers, ceramic fibers, glass fibers, polymer fibers (eg aramid) and theirs Mixtures, based on the total weight of the respective fiber layer. Particularly preferably, the device layer is applied without additional transverse adhesion.
  • the fiber layer may also contain random fiber layers.
  • FIG. 2 shows two-ply fiber scrims with a device layer of + 45 ° and -45 ° and with a device layer of + 0 ° and 90 °.
  • Preference may also Wirrfaserlagen, nonwovens, nonwovens, random fiber nonwoven fabrics and other textile structures such as nets or films may be included above, below or in the middle of the fiber layers.
  • the fiber webs are preferably used for wind power plants, for automobiles, ships, for the aerospace industry, for rail vehicles and the other transport sector, sports equipment as well as the construction and construction sector.
  • the finished device layers are preferably stored refrigerated before they are then fed to the subsequent installation process.
