Definitions

  • the present invention relates to an endless ultra-thin carbon fiber, a method for producing such an ultra-thin carbon fiber, the use of such a carbon fiber and a corresponding carbon precursor fiber.
  • Ultrathin fibers also called microfibers, are used in many technological applications. These include, for example, applications in medical technology both for implants and for medical devices, in filter technology for filtering ultrafine dusts or in textile technology for producing textiles.
  • microfibers are used in a variety of applications. Examples include the use of polymer microfibers for functional textiles in the clothing industry and for industrial applications in filter technology, where such textiles are used because of their high specific reactive surface area.
  • microfibers made of glass or carbon or carbon are used for the production of fiber composite components for lightweight structural components that have to provide supporting functions with low weight.
  • carbon fibers are of great importance for the production of highly stable, eg highly rigid fiber composite lightweight components, which will increase in the future.
  • composite components made from carbon-fiber-reinforced plastic (CFRP) are now used in aircraft construction, in automotive engineering and in the manufacture of rotor blades for wind power plants.
  • microfibers with a fineness of 1 dtex or less by means of electrospinning.
  • electrospinning has the disadvantage that it is difficult to control and less productive and is therefore mainly used for special products, especially in the field of filter technology for ultrafine dusts.
  • Another object of the present invention is to provide a method by which such a carbon fiber can be easily and inexpensively manufactured.
  • a carbon fiber which comprises at least one monofilament, wherein at least one of the at least one filament according to DIN EN ISO 1973 certain filament diameter of 4 ⁇ or less.
  • At least one of the at least one filament of the carbon fiber which comprises at least one monofilament, has a filament diameter of 4 ⁇ m or less determined according to DIN EN ISO 1973. If the carbon fiber has two or more filaments, such as 6,000 filaments, therefore, at least one of these 6,000 filaments has a filament diameter of 4 ⁇ or less.
  • At least one of and preferably all of the monofilaments of the carbon fiber has a tensile strength of 50 cN / tex or more, preferably 65 cN / tex or more, and particularly preferably determined according to DIN EN ISO 5079 of 70 cN / tex or more.
  • FIG. 4 shows an SEM cross-sectional image of the carbon precursor fiber shown in FIG. An evaluation of the cross sections reveals that the carbon precursor fiber according to the invention has a length to width ratio L / B of 1.22, i. the individual filaments have a nearly circular cross-sectional area.
