  • the wedge shape of the intermediate spaces 24, 25 between the leg surfaces 18, 19 of the core element and the inner surfaces 31, 32 of the longitudinal side walls 26, 27 thereby favors the highest possible degree of filling of these intermediate spaces 24, 25.
  • the filler and adhesive 28 which is preferably based on polyurethane, is formed by a flowable in the processing state and low-viscosity and curing under room temperature, two-component mixture of a polyol and an isocyanate. These Components are mixed shortly before processing or in the course of processing and, using an injection process (RIM) in the shaping molds 46, 47 - Fig. 4 - Introduced or pressed between the individual layers or layers of composite body 4 to be produced.
  • RIM injection process
  • the in the original state relatively liquid or easily flowable filling and adhesive 28 in the cured state has a density of between 1000 to 1200 kg / m 3 , preferably of about 1100 kg / m 3 , and a hardness between 60 to 90 Shore-D, preferably from about 70 Shore D.
  • the particularly efficient or economical curing of the filler and adhesive 28 is achieved inter alia by a filler and adhesive 28 based on polyols and isocyanates to be mixed.
  • the sliding board body 3 or the one-piece composite body 4 to be produced after removal from the pressing device 45 is stored stress-free and stress-free at about room temperature, and thereby the curing time of the filling and adhesive 28 before further processing of the multi-layer sandwich element, especially before a grinding or cutting processing of interfaces of the sliding board body 3, is awaited.
  • a grinding, cutting or machining for example, provided the longitudinal side walls 26, 27 of the composite body 4 with respect to the tread surface 11 trapezoidally inclined or slightly inclined towards the core member 7 extending longitudinal side surfaces 14, 15, as in Fig. 2 in full lines or in Fig. 4 illustrated with dashed lines.
  • the inclination of these longitudinal side surfaces 14, 15 of the sliding board body 3 with respect to a vertical plane is preferably between 2 ° and 6 °, preferably approximately 4 °.
  • the exemplary embodiments show possible embodiments of a ski 1, a semi-finished product 40 and related manufacturing method, it being noted at this point that the invention is not limited to the specifically illustrated embodiments thereof, but rather also various combinations of the individual embodiments are possible with each other and this Variability due to the teaching of technical action by objective invention in the skill of those working in this technical field is the expert. So are all conceivable embodiments, which are possible by combinations of individual details of the illustrated and described embodiment variant, includes the scope of protection.
