Definitions

  • auxetic materials which show exactly the opposite behavior, ie which, when a tensile stress is applied, stretch in the direction of the tensile strain and thicken perpendicularly thereto. Such materials are characterized by a negative Poisson number and are referred to as so-called auxetic materials.
  • auxetic cells that are also suitable as components of layer composites in which several of these flat components are placed one above the other and connected to one another, for example by welding, gluing or other techniques.
  • Layers of conventional materials can be arranged between the components according to the invention. You can also choose materials that show auxetic behavior themselves.
  • Figure 1 Comparison of a conventional honeycomb structure with an auxetic lattice structure
  • FIG. 6 embedded components according to the invention with auxetic
  • FIG. 9 an auxetic network lying between two material webs
  • FIG. 10 a hollow profile with an auxetic structure arranged inside
  • Each of the cell wall areas 2 is preferably designed to be rigid, so that possible loads on the cell structure without deformation of the wall areas 2 into the whole Cell structure are initiated and the cell structure extends by means of a movement of the wall areas 2 against each other over the connection node 3.
  • FIG. 14 shows the equivalent arrangement of a non-auxetic or auxetic structure 6 (e.g. a foam) on the outer auxetic surface of the hollow profile 5 according to FIG. 13 and FIG. 15 shows the arrangement on both sides.
  • a non-auxetic or auxetic structure 6 e.g. a foam
  • FIG. 15 shows the arrangement on both sides.
  • it can be provided with an arrangement on both sides to use the same or different materials on both sides.
