Definitions

  • the present invention relates to strip-shaped semifinished products which are suitable for producing composite materials, in particular fiber-reinforced thermoplastics.
  • thermoplastics For the production of fiber-reinforced thermoplastics. These generally consist of reinforcing fibers arranged in a band, which are melt-impregnated with thermoplastic material. Such semi-finished products are stiff and do not have the drapability of textile fabrics.
  • DE-C-23 20 133 nonwovens made of unidirectionally arranged carbon fibers are known, which are impregnated with adhesive and which are held together by threads of thermoplastic material arranged perpendicular to the carbon fibers by melting these threads.
  • DE-GBM 85 21 108 describes textile reinforcements for the production of layer structures from longitudinal and transverse thread layers. The number of crossing points between warp and weft threads is kept as low as possible. This is achieved there by an arrangement of superimposed longitudinal and transverse thread layers, which are interconnected by additional longitudinal threads made of thermoplastic material. Further configurations of textile reinforcements are described in EP-B-193 478, EP-B-193 479 and EP-B-198 776.
  • DE-A-18 08 286 discloses nonwovens which consist of statistically stored threads or fibers and which have at least one thermoplastic polymer material. These nonwovens are characterized in that a consolidation has been carried out in part of the nonwoven, a certain number of binding points per unit area having a specific cross-sectional area of the binding point tips being generated in this part.
  • the consolidation is e.g. by treating the fleece with a heated press that has a textured surface.
  • DE-A-34 08 769 discloses a process for the production of fiber-reinforced molded articles made of thermoplastic material, in which flexible textile structures are used which consist of reinforcing fibers that are largely unidirectional or parallel and a matrix composed of thermoplastic yarns or fibers . Essentially knitted fabrics made of these fibers are described, or strands or ribbons. These semi-finished products are then only deformed by heatable profile nozzles when they are finally shaped, with practically all thermoplastic fibers being melted.
  • the semi-finished products according to the invention have an essentially homogeneous distribution between the different types of fibers and the orientation of the reinforcing fibers is largely unidirectional.
  • the drapability of the semifinished product according to the invention corresponds approximately to that of a woven or knitted fabric of the same basis weight made of these fibers and has the advantage over a woven or knitted fabric that the fibers are unidirectionally oriented and thus alignment of the fibers by stretching in the subsequent thermal shaping process can be omitted.
  • the invention relates to a band of essentially unidirectionally oriented reinforcing fibers and thermoplastic matrix fibers. It is characteristic of the tape according to the invention that it is essentially composed of yarns containing reinforcing fibers and / or matrix fibers, the yarn density of the tape is about 5 to 20 yarns / cm width, the titer of the yarns is about 1000 to 3000 dtex and the matrix fibers are locally melted or melted on at least one strip surface, forming solidification points.
  • the term “yarn” is to be understood as meaning multifilament yarns, staple fiber yarns, mixed yarns made of multifilaments and staple fibers and also monofilaments.
  • the term “fiber” is understood to mean both staple fibers and endless filaments.
  • the yarn density of the tape is chosen so that the distance between the yarns making up the tape is not too great, so that it is still possible to form consolidation points between adjacent yarns.
  • the distance between the yarns in the band should be less than about three times the diameter of a monofilament from the titer of the yarns.
  • the titer of the yarns made of reinforcing and / or matrix fibers is generally 1000 to 3000 dtex, preferably 1500 to 2500 dtex.
  • Reinforcing fibers and matrix fibers can be in the form of separate yarns as well as mixed yarns. Bicomponent fibers made of reinforcement and matrix components can also be used. The reinforcing fibers in the yarns are preferably in the form of multifilaments. Mixed yarns made of reinforcing and matrix fibers are very particularly preferably used.
  • Blended yarns can be made using any of the conventional blending techniques such as Ring or 3-cylinder spinning, commingeling techniques, mixed twisting or DREF techniques.
  • multifilament blended yarns made from reinforcing and matrix fibers in which at least part of the yarn consists of high-modulus individual filaments of an initial modulus of more than 50 GPa, in particular more than 80 GPa, which are mixed by means of a mixing medium, preferably air, are available, wherein the high modulus individual filaments have been preheated to a temperature of 0.25 Ts to 0.9 Ts prior to mixing and the mixing takes place at a temperature at which the matrix fibers are essentially retained; in particular, the mixing is carried out in the non-heated mixing medium.
  • Ts means the melting or decomposition temperature of the high modulus single filaments in ° C.
  • These particularly preferred multifilament blended yarns are characterized in that the average mixing distance of the yarn, measured in the needle test, is less than 150 mm and that the number of breaks in the individual filaments, measured in the light barrier method on one side of the yarn, is less than 20 / m .
  • non-meltable or high-meltable, high-modulus and / or high-strength fibers can be considered as reinforcing fibers. These fibers are selected so that they do not yet melt under the processing conditions suitable for the thermoplastic fiber fractions or practically do not deform thermoplastic and are present as reinforcing fibers in the resulting composite material.
  • Such fibers are glass fibers, carbon fibers, fibers of various metals and Metal alloys, from a wide variety of metal nitrides or carbides, metal oxide fibers or fibers from organic polymers, such as from polyacrylonitrile, polyester, aliphatic and aromatic polyamide or polyimide.
  • Glass, carbon, metal or aramid fibers are preferably used.

  • Bicomponent or multicomponent fibers can also be used in particular as thermoplastic fibers, for example of the core / jacket type or of the side / side type or of the matrix / fibril type.
  • the semi-finished product according to the invention is so solidified by local melting of the matrix fibers that it can be handled without problems without losing its tape shape, but at the same time has good drapability, rollability and transportability.
  • the semi-finished product according to the invention can be stored almost indefinitely and indefinitely, since there are practically no curing components.
  • the consolidation points are located at least along one surface of the belt, but can also be along both surfaces. It may be sufficient in individual cases that only a surface fixation of the tape has taken place.
  • the local consolidation points run practically through the cross section of the entire band.

  • the mean free distance between two fastening points is preferably about 1 to 5 cm.
  • the density of the solidification points along the surface will depend, among other things, on the type and amount of the thermoplastic fibers and on the ratio of thermoplastic and reinforcing fibers. It is also possible to apply a pattern of solidification points to the tape, i.e. to provide only parts of the surface of the belt with consolidation points.
  • Usual values for the density of consolidation points are in the range from 40 to 500,000 points / m2 surface, preferably 100 to 40,000 points / m2 surface (with one-sided application of consolidation points to the surface; with two-sided Applying usually half the density per surface is sufficient).
