  • the fibers thus produced exhibit different strengths and stiffnesses with a relatively small elongation at break in the axial direction.
  • Common carbon fibers of higher tensile strength are those of polyacrylonitrile (PAN), which are produced by pyrolysis under inert gas. The fibers are then bundled into so-called filament yarns.
  • the number of filaments is given in thousands by the letter “K” and, for example, by their weight in grams per 1000 meters in “tex”.
  • the specification 400tex (6K) stands for a weight of 400 g / 1000 m filament yarn and means that 6000 individual fibers are combined into one yarn.

  • Cords with carbon fibers are also used as tension elements in suspension elements z. B. used for elevator technology. Since the said cords in the prior art usually consist of a multiplicity of very thin carbon filaments which, after carbonization, lie almost parallel in fiber bundles, certain disadvantages arise in the further processing. From the fiber bundles with parallel fibers, yarns for a wide variety of cord constructions are usually produced by twisting, twisting or hitting, as also mentioned in WO 2011/038200 AI in the comprehensive assessment of the state of the art there.

Abstract

L'invention concerne un moyen de transmission de traction et/ou de force en matériau élastomère, en particulier dans une transmission par lien souple. Le moyen de transmission de traction et/ou de force comporte des renforts prenant la forme de câbles incorporés, dans lesquels sont disposés respectivement un ou plusieurs faisceaux de fibres ou fils continus formés et orientés, qui comportent au moins en partie des fibres de carbone comme filaments. Les fibres de carbone, avant leur carbonisation, sont amenées dans la forme et l'orientation qu'elles occupent dans les faisceaux de fibres ou les fils continus du câble.
