Definitions

  • the invention relates to the field of gliding boards or rolling intended for the practice of a sport, such as surfing on snow or water, skiing on snow or water, skateboard or wheeled board, or other.
  • a board traditionally has a length measured in a longitudinal direction between a first end and a second end, a width measured in a direction transverse between a first edge and a second edge, and a height measured between a bottom and a top.
  • the board In the sense of height, the board traditionally comprises a lower reinforcement, a core, and an upper reinforcement.
  • the term “lower” refers to the reinforcement closest to the ground when the board is slipping or rolling under normal conditions of use.
  • the qualifier “superior” designates the reinforcement farthest from the ground.
  • the core meanwhile, is intended to separate the reinforcements.
  • the board has a sandwich structure, which is both lightweight and mechanically resistant. This is particularly the case in snow surfing, or snowboarding.
  • a user has both feet retained on the board, respectively in a first and a second reception area.
  • the feet are each oriented in a substantially transverse direction of the board. This facilitates lateral support, with the heels or toes of the feet.
  • the board During driving the board is mechanically stressed. In particular, it receives pulses, to make turns, figures, or jumps. In other words efforts are exerted on the board, by the user, to manage the trajectories and changes of direction.
  • each reinforcement is thick enough to give the board the desired mechanical characteristics.
  • the thickness of the reinforcements is not excessive, to avoid unnecessary burdens. It is a question of finding a compromise between mechanical resistance and weight of the board.
  • Fibers or fabrics impregnated with resin are fibers or fabrics impregnated with resin.
  • the fibers may be glass, carbon, aramid, or any equivalent. These composite materials impart both lightness and mechanical characteristics that give a board satisfactory properties.
  • one of the aims of the invention is to reduce the weight of the board, without altering its mechanical properties.

  • the natural fibers of the first layer 40 of the lower reinforcement 22 comprise bamboo
  • the natural fibers of the first layer 41 of the upper reinforcement 24 comprise bamboo. It can be expected that all the natural fibers of the first layers 40, 41 are bamboo. This simplifies the manufacture of the board 1.
  • the bamboo has a density of the order of 0.6 to 0.7 kg / dm 3 .
  • the density of bamboo is much lower than that of an artificial material, such as glass, which has a density of between 1.3 and 1.6 kg / dm 3 .
  • the first layer 40 of the lower reinforcement 22 comprises fibers 42 oriented longitudinally. This means that the fibers 42 extend parallel to the longitudinal axis Lo of the board. In fact, the first layer 40 is unidirectional, in the sense that it exclusively comprises longitudinally oriented fibers.
  • the first layer 41 of the upper reinforcement 24 comprises fibers 43 oriented longitudinally. Again the fibers 43 extend parallel to the longitudinal axis Lo of the board.

  • the transverse fibers 52 give the board 1 good resistance to transverse bending along a longitudinal axis.
  • the upper reinforcement 24 also comprises a first layer 60 of artificial fibers.
  • This layer 60 itself comprises longitudinal fibers 61, oriented along the direction Lo, as well as transverse fibers 62, oriented along the direction Wo. Again the fibers 61,62 can be woven or superimposed, and impregnated with a binder.
  • the layer 60 comprises glass fibers, for example with a density of 300 g / m 2 for the longitudinal fibers 61 and a density of 180 g / m 2 for the transverse fibers 62. A good compromise is obtained between weight and mechanical resistance.
