Definitions

  • the invention relates to a process and an apparatus for the manufacture of a tubular reinforcing fibre material or structure of reinforcing yarns, especially a knitted inlay fabric, more particularly for the reinforcement of a matrix material, in which reinforcing filaments or reinforcing yarns extending in one or more directions of the tube are provided, which are interconnected with binder or stitching yarns by a connecting unit, such as a circular knitting unit. Further, the invention comprises the tubular reinforcing material and uses thereof.
  • Such a tubular reinforcing material in the form of a knitted inlay fabric may be considered known from the paper "A new materials approach for providing transverse strength in pultruded shapes" by Rick Birsa and Paul Taft delivered at the 39th Annual Conference of The Society of the Plastics Industry, Inc. dated 16-19 Janary, 1984.
  • three knitted inlay fabrics manufactured on a circular weft knitting machine are described, viz. WEFTFAB® COFAB®, and WARPFAB®.
  • Each of these three knitted inlay fabrics contains reinforcing yarns of glass.
  • the knitted fabrics WEFTFAB and WARPFAB only contain reinforcing yarns in one single principal direction of the knitted fabric, viz.
  • the knitted fabric of the COFAB type contains reinforcing yarns in two principal directions, viz. in both the warp and weft directions.
  • the various reinforcing yarns are interconnected to form a cohesive circular knitted inlay fabric by the knitting stitches formed by the stitching yarns.
  • the reinforcing yarns extend only in one of the two principal directions of the circular knitted fabric or in both, i.e. in longitudinal direction of the tube and/or transverse to the longitudinal direction of the tube. Consequently, such known tubular knitted inlay fabrics can be used only on a limited scale for the manufacture of the nowadays increasingly used modern fibre-reinforced plastics of composite material.
  • DE-A 33 39 205 describes a flat laminate of reinforcing yarns and a process and a machine for the manufacture of such a laminate.
