Definitions

  • the present invention relates to hybrid yarns for composite materials with a thermoplastic matrix, especially in the case where this matrix is made up of thermoplastic fibers as well as their process for obtaining.
  • the reinforcing fibers carbon, aramid or glass
  • the reinforcing fibers which are generally found in the form of multifilaments, are woven alternately with multifilaments of thermoplastic matrix fibers .
  • thermoplastic matrix fibers belong to the conventional families: polyether ether ether ketone (PEEK), polyphenylene sulfide (PPS), polyetherimide (PEI), etc.
  • This manufacturing technique has many disadvantages, among which we can cite: - poor wettability, - a high vacuum rate, - delamination of the reinforcing fibers.
  • Another technique consists of intermingling the multifilament of reinforcing fibers with the multifilament of thermoplastic fiber.
  • the present invention has set itself the aim of proposing hybrid wires for thermoplastic matrix composites making it possible to control and solve these problems.
  • the hybrid yarns according to the invention are characterized in that they consist of an intimate mixture of yarns of reinforcing fibers and yarns of thermoplastic matrix fibers, each of the yarns of fibers having been obtained beforehand by cracking according to a slow drawing and progressive multifilaments.
  • the yarns of reinforcing fibers are chosen from yarns of carbon, aramid or glass fibers.
  • thermoplastic matrix fibers are chosen from yarns of polyether ether ketone fibers (PEEK), of phenylene polysulfide (PPS), polyethersulfone (PES), polyetherimide (PEI), as well as among the other fiber yarns known for this purpose, such as polyamides and polyimides.
  • PEEK polyether ether ketone fibers
  • PES phenylene polysulfide
  • PES polyethersulfone
  • PEI polyetherimide
  • the relative proportions of the reinforcing fibers and of the thermoplastic matrix fibers are situated around 65% for reinforcing fibers and 35% for thermoplastic matrix fibers.
  • the invention also relates to a process for obtaining hybrid wires for composite materials according to the invention.
  • multifilaments of reinforcing fibers and multifilaments of thermoplastic matrix fibers are subjected to a separate process of cracking by slow and progressive drawing, then the ribbons of staple fibers thus obtained are assembled on a drawing machine of intersecting type, the ribbon leaving this stretching machine then being assembled on a second stretching machine with other identical ribbons, this operation being repeated several times so as to produce the most intimate mixture possible, the final ribbon obtained then being subjected in conventional long fiber spinning operations: passage on a spindle bench, actual spinning, winding, assembly and twisting.
  • the yarns thus obtained are capable of being transformed by weaving, knitting or braiding to obtain composite materials having numerous advantages over materials of the same type obtained according to the processes of the prior art.
  • the composite obtained also exhibits very good aptitudes for hot stamping.
  • the reinforcing fibers are generally designated by 2 and the thermoplastic matrix fibers by 3 .
  • the multifilament cables supplied from the coils 10 are subjected to a cracking operation by stretching and controlled breaking, the speeds of the stretching zones 11,12 and of the cracking zones 13,14 gradually increasing so that: V10 ⁇ V12 ⁇ V13 ⁇ V14 which makes it possible to obtain at the outlet a ribbon of staple fibers whose average length is perfectly controlled.
  • This length is moreover illustrated by the diagram of FIG. 1 on which the lengths of fibers in mm are plotted on the ordinate and the abscissa is the population of fibers expressed as a percentage of the number of fibers in this population.
  • This ribbon then undergoes conventional spinning operations in the long fiber technique: - passage on pin benches, - spinning, - winding, - assembly, - twisting, which makes it possible to obtain the hybrid fiber yarn for composite materials with a thermoplastic matrix according to the invention, this fiber yarn being, of course, capable of being subsequently transformed by weaving, knitting or braiding.
  • thermoplastic matrix fiber melts by trapping the reinforcing fibers.
  • the performance of the composite thus obtained therefore depends only on the characteristics of the elementary fibers and their attachment to the thermoplastic matrix.
  • Table I summarizes the properties of three types of hybrid fiber yarns according to the invention in which both the reinforcing fibers and the thermoplastic matrix fibers have been varied.
  • Table II compares the properties of different composite materials produced from hybrid fiber yarns according to the invention, compared to composites produced according to the prior art and described in the literature.
