Definitions

  • the present invention relates to a woven material that has been reinforced for improved handling during the manufacturing process, a component incorporating the reinforced nonwoven material, and its use.
  • the present invention relates to a carbon fiber nonwoven with a reinforcing grid contained therein.
  • DE 92 07 367 U1 Disclosed in DE 92 07 367 U1 is a laminate whose surfaces were formed using spunbonded fabric, and which consists of at least two layers of spunbonded fabric and at least one scrim layer, preferably a scrim layer made out of reinforcing yarns, wherein the scrim layers or scrim layer lie(s) between a respective two spunbonded fabric layers (DE 92 07 367 U1, page 2, 2 nd complete sentence).
  • DE 10 2006 060 241 A1 discloses a carrier insert comprised of a flat textile structure and a reinforcement, in which the flat textile structure, which already exhibits the reinforcement, was solidified hydrodynamically. Described in particular are spunbonded fabrics, which are generated by randomly depositing freshly melt-spun filaments, and consist of endless synthetic fibers made up of melt-spinnable polymer materials (DE 10 2006 060 241 A1, paragraph [0036]).
  • EP 1 584 737 A1 discloses a strengthened, flat nonwoven, which encompasses at least two layers of endless fiber nonwoven made of polyester and a glass fiber grid secured between the nonwoven layers.
  • carbon fibers in terms of manufacturing technique has to do with the composition of the carbon fiber surface.
  • carbon fibers in flat textile structures exhibit a very weak adhesion between the fibers, and hence lead to a low cohesion between the flat textile structures.
