Definitions

  • the invention relates to a ski with an inner construction made of one or more synthetic resin-fiber tubes.
  • the object of the invention is to improve the processing of the synthetic resin-fiber material tubes in the mold cavity.
  • the fibrous structure of a tube is designed as a tube made of textile knitted fabric.
  • the tubular fibrous structure for the synthetic resin-fibrous tubes can preferably consist of knitted knitted fabric, but basically of knitted knitted fabric.
  • the knitted fabric preferably consists of threads made of glass fibers and / or carbon fibers.
  • Fig. 1 shows a manufacturing stage of a ski and Fig. 2 shows a cross section of a finished ski.
  • the components of the ski have been inserted into the mold cavity between the lower mold 10 and the upper mold 14 and the production mold has been closed.
  • the inserted ski components consist of the outsole covering 1, the steel edges 2, the cover film 8 (shell), preferably made of unreinforced plastic, the synthetic resin-fiber material tubes 11 and the inner (and folded) hoses 12 made of airtight plastic material.
  • the also tubular fibrous structure in the synthetic resin-fibrous tubes consists according to the invention of textile knitwear, e.g. a tubular knitted fabric made of threads, preferably made of glass fibers and / or carbon fibers.
  • the tubular fibrous structures made of knitted fabric are covered with a synthetic resin, e.g. Epoxy resin, soaked.
  • the inner tubes 12 are e.g. connected to a compressed air supply at one of the longitudinal ends of the mold cavity.
  • the inner thighs 12 are inflated, whereby they expand and / or expand.
  • the cover sheet 8 lies against the inner mold wall of the upper mold 14 and the synthetic resin-fiber material tubes 11 are deformed such that they - as a hollow body - fill the interior between the cover sheet 8 and the lower assembly 1, 2 of the ski, finally - after the plastic has hardened - a ski with a cross section according to FIG. 2 is produced.
  • tubular fibrous structures of the synthetic resin-fibrous tubes 11 made of knitted fabric, e.g. knitted knitwear, because the height of the interior varies in the course of the longitudinal extent of the ski and therefore a different stretching of the synthetic resin-fibrous tubes 11 is required depending on the longitudinal position.
  • the wall 5,5 ', 6,6' of the hollow chambers consist of fiber-reinforced plastic and consist of the deformed and hardened tube walls of the synthetic resin-fiber material tubes 11 (FIG. 1).
