Definitions

  • the present invention relates to a method and an apparatus for the production of carbon fiber semi-finished carbon fiber yarns.
  • Another object of the invention is a carbon fiber tape obtainable by the method and its use.
  • carbon fiber wefts and / or flakes are processed by a carding process and provided as a card sliver.
  • the purpose of the carding process is the dissolution of the carbon fiber wefts and / or flakes into individual fibers or fiber bundles and their orientation along the fiber axis.
  • the fibers are largely oriented and are suitable for further processing up to the desired end product.
  • the WO 2011/134995 in turn, describes a hybrid yarn for making molded articles consisting of a core of rectilinear staple fibers and a sheath of staple fibers wound around the core.
  • the staple fibers each consist of reinforcing fibers embedded in a thermoplastic matrix.
  • a method for producing a sewing thread from carbon fiber materials is described.
  • the fibers of the sewing thread described are staple fibers of finite length of stretched or cut multifilament yarns which are spun together to form a yarn and coated or impregnated.
  • the recycled carbon fibers can come from different sources and are obtained by cutting a recycled carbon fiber material.
  • the method described comprises separating, digesting, blending, and spinning the carbon fibers into a yarn.
  • the EP 1 854 911 A1 describes a hybrid carbon fiber spun yarn having a core region and an outer region surrounding the core region. At least 20% by mass of the fibers in the core region are "long" carbon fibers having a length of 500 mm or more, and in the outer region at least 80% by mass of the fibers are “short” carbon fibers having a fiber length of less than 500 mm.
  • the EP 1 696 057 describes a method of making a carbon fiber ribbon starting from a mat of stacked, pitch-oriented oriented grain carbon fibers. The obtained carbon fiber ribbon is pulled and twisted to obtain a carbon fiber spun yarn having 50 to 400 primary twist / m and at least 3 wt% of fibers having a fiber length of at least 150 mm.
  • Carbon fibers also known as carbon fibers, are industrially produced fibers from carbonaceous organic feedstocks that are converted to graphitic carbon by pyrolysis. It is possible to distinguish isotropic and anisotropic types of carbon fibers.
  • the isotropic carbon fibers have only low strengths and less technical importance. Due to their chemical structure, the anisotropic carbon fibers show high strengths and stiffnesses with low elongation at break in the axial direction and are of great industrial significance. Due to these properties, carbon fibers are only extensible to a very small extent and are also susceptible to forces acting transversely to the fiber longitudinal axis. Processes known in the prior art for the production of carbon fiber semifinished products therefore usually lead to a significant reduction in the average fiber length and to loss of strength due to the process.
  • the present invention is therefore based on the object to provide an improved process for the processing of carbon fiber entanglements, in which the aforementioned disadvantages are avoided.
  • a fiber-sparing preparation of carbon fiber worms is to be made available in which the structural and mechanical properties of the processed carbon fibers are preserved or only slightly damaged.
  • the average fiber length of the carbon fibers should be largely retained from the carbon fiber entanglements used.
  • the method should be procedurally simple to implement and with little structural effort.
  • carbon fiber worms can be separated in a technologically simple manner in a turbulent air stream into fiber bundles or individual fibers.
  • the thus separated carbon fibers can be stored with a high degree of orientation of the individual fibers or fiber bundles in the fiber longitudinal direction to a band.
  • a fiber band produced in this way can be subjected to a suitable binding agent and thus solidified for the purpose of fixing or connecting separated individual fibers to one another.
  • a sliver produced in this way can be profiled or shaped and provided for further processing steps.
  • the semi-finished carbon fiber products are obtained in or subsequent to step d).
  • processing means a recycling process by recycling for the reuse of Fasergewirren be processed in the defined waste streams or parts of Fasergewirren to recover from it again marketable secondary raw materials.
  • the intention is to exclude the use of energy and the preparation of materials intended for use as fuel or for backfilling.
  • fiber structures are understood to mean flat or spatial structures, such as scrims, woven fabrics, braids, knitted fabrics, knitted fabrics, flakes and any combination thereof.

  • carbon fiber semifinished products are band, line and / or thread-like structures made of carbon fibers.
  • the semi-finished carbon fiber products are obtained in or following step d).
  • they may be subjected to a fabrication in one or more further steps.
  • Carbon fiber semi-finished products obtained in accordance with the invention generally contain carbon fiber constituents of at least 50% by weight, for example in the range from 50 to 100% by weight, preferably at least 60% by weight, for example in the range from 60 to 100% by weight preferably at least 75 wt .-%, for example in the range of 75 to 100 wt .-%, in particular at least 90 wt .-%, for example in the range of 90 to 100 wt .-%.
