Definitions

  • the invention relates to the field of boards for gliding on snow or on water, and in particular alpine, cross-country or touring skis, or else snowboards or wakeboards.
  • the invention relates more particularly to a gliding board including on its visible face a decorated composite material as well as the associated manufacturing method.
  • the invention has the advantage of allowing the production of a decoration on the gliding board without integrating an additional layer supporting the decoration.
  • this embodiment allows in particular an interesting weight saving.
  • a ski is identified by the various markings and patterns present on the visible face of the ski.
  • the decoration makes it possible to give an advantageous aesthetic appearance.
  • the document EP 0 774 365 proposes a process for decorating a gliding board made of hardened composite material.
  • a layer of transparent plastic material is previously decorated on its underside by transfer of sublimable inks, then is thus glued to the surface of the composite material.
  • the product obtained comprises an additional layer which adds to the overall weight of the gliding board.
  • this is not sought in the context of gliding boards, which must be ever lighter in order to improve their behavior on the snow.
  • the document US 6,004,900 describes a sporting article, typically a hockey stick, comprising an outer layer of hardened composite material, the resin of which contains light-colored pigments.
  • the decoration is printed on the article by sublimation of an ink in the surface layer of the composite material. Sublimation takes place when certain pressure and temperature conditions of around 160 to 180°C are applied, allowing the ink to temporarily pass into a gaseous state. However, during its sublimation, the ink in the gaseous state diffuses into the resin so that the contours of the decoration obtained are not clear.
  • An example of ink scattering is shown in figure 1 below, on which a continuous sheet of ink 31 is observed, which gradually melts into the resin 23, a sign that the ink 31 diffuses into the resin 23.
  • the method requires the prior mixing of color pigments clear with resin, otherwise the sublimated ink lacks contrast. However, this additional step complicates the process. It is also impossible to obtain solid white areas directly by sublimation.
  • the document US 5,718,792 presents a method of decorating a ski pole made of hardened composite material.
  • a decoration sheet pre-printed with sublimation ink is applied to the surface of the stick.
  • the assembly is heated, for example, to a temperature of approximately 210° C. for 60 to 80 seconds, to allow the ink to pass directly into the gaseous state. by sublimation of the decoration in the stick.
  • the transferred decoration does not have a clean appearance, because the ink diffuses in the resin, particularly in the case of a curved surface, since the positioning of the pre-printed decoration sheet on the stick is a delicate step. and not very reproducible.
  • the high temperatures applied in the processes implementing sublimation are incompatible with applications on articles including materials sensitive to heat, such as for example the polyethylene gliding soles on a ski.
  • the technical problem that the invention sets out to solve is therefore to develop a method of manufacturing a gliding board for which the decoration printed on the composite material of the gliding board forms the least possible extra thickness, is clean and does not diffuse into the resin, while being resistant to wear and external attacks.
  • the “curable” resin can be a resin commonly qualified as thermosetting, that is to say which hardens by crosslinking when the temperature and pressure conditions are applied.
  • the resin can be a thermoplastic resin, which hardens on cooling, after having been softened by applying appropriate pressure and temperature conditions.
  • the resin therefore has a dual function of stiffening the composite and receiving element of the decoration. It is therefore no longer necessary to add additional layers of decoration, which makes it possible to achieve an interesting gain in thickness and weight.
  • the method makes it possible to transfer a pattern onto a gliding board without changing the state of the ink and therefore without diffusion, and without deformation or loss of sharpness of the pattern.
  • the pattern to be transferred onto the gliding board is printed on a transfer film by screen printing or inkjet printing.
  • the ink used is initially in the liquid state.
  • the method therefore comprises a step of crosslinking the polymer making up the ink.
  • Cross-linking is initiated by an external energy input.
  • the energy input can come from contact with ambient humidity, from an increase in temperature or from exposure to UV light.
  • the ink in solid form obtained has a structure which has no melting point, does not soften but is degraded or carbonized when it is heated above a certain temperature.
  • This degradation or carbonization temperature is higher than the conditions of the gliding board manufacturing process.
  • the transfer film ideally has at least one of the following properties.
  • the transfer film is deformable, that is to say it can bend and/or stretch to adapt to the three-dimensional geometry of the external surface of the composite material.
  • the printed transfer film is positioned by folding it to adapt it to the three-dimensional external surface of the composite material.
  • the transfer film is made of a material chosen from polyolefins. This family of materials has good properties of lightness and resistance to cracking and tearing.
  • the adhesion force between the grains and the film is strong enough for the pattern not to move on the film during the movement and positioning of the transfer film in contact with the resin.
  • the adhesion force between the ink grains and the resin is preferentially greater than the adhesion force between the ink grains and the transfer film.
  • the softening temperature of the transfer film is advantageously higher than the temperature generating the softening and/then the hardening of the resin to avoid deformations of the pattern or the incrustation of a portion of the transfer film in the resin.
  • the process of decorating the gliding board can be carried out in two ways.
  • the method may include a step of positioning the composite material in a mould, the pressure and temperature conditions generating the softening and / then the hardening of the resin then being applied to said mold.
  • the mold corresponds for example to the mold in which the gliding board is assembled.
  • the temperature generating the softening and/or hardening of the resin applied during the molding is less than or equal to 120° C., so as not to degrade the heat-sensitive elements, such as for example the polyethylene ski soles.
  • the pressure and temperature conditions are applied only to the layer of composite material, then assembly in a mold is carried out subsequently.
  • the invention relates to a gliding board obtained by the method according to the first aspect of the invention.
  • the gliding board includes on its visible face a decorated composite material, formed of a fibrous layer coated with hardened resin.
  • Such a gliding board is characterized in that said decorated composite material comprises a pattern composed of an arrangement of grains of at least one type of ink, said ink comprising dyes and a crosslinked polymer, these grains being embedded in the surface layer of the cured resin of the composite material.
  • a composite material is composed of a fibrous layer coated with hardened resin.
  • the resin may be a thermoplastic resin, which hardens when it cools, or a thermosetting resin which hardens by chemical reaction phenomena.
  • a thin layer of the resin remains supernatant relative to the fibrous layer and constitutes the surface layer in which the grains can become embedded.
  • “encrusted” means that a portion of the volume of the ink grain is encompassed by the resin.
  • a large portion, ideally a majority, of the outer surface of the grain is in contact with the resin.
  • the grain may be completely embedded and isolated in the resin or else its upper surface may protrude into the open air or even at least one of its lateral zones may be contiguous with another grain.
  • the ink grains do not enter inside the fibrous layer, which makes it possible to preserve the mechanical strength properties of the composite material.
  • the encrusted ink grains are point and non-diffuse elements, like pixels, and it is possible to distinguish them under a microscope. They then appear in isolated form or in the form of aggregates of resin-embedded grains.
  • the decoration is encrusted in a very thin layer of resin.
  • the ink grains are totally covered by the resin, they remain clearly visible by transparency and have clear and precise contours.
  • the decor is protected by the resin that surrounds it and is resistant to mechanical and chemical attack. This also allows better resistance to abrasion and tearing.
  • the gliding board does not have any additional thickness linked to the addition of the decoration, which makes it possible to gain in lightness compared to the gliding boards of the state of the art.
  • the polymer constituting the ink is chosen from the group including polyacrylates, polyacrylics and polyurethanes. Inside the decoration affixed to the gliding board, these polymers are in crosslinked form, so that the ink grains are in the solid state and adopt a three-dimensional configuration. Unlike state-of-the-art gliding boards, any dye color can be used, even white, while maintaining sufficient contrast with the resin to clearly distinguish the decor.
  • the number of grains present per unit area of the surface of the decorated composite is between 2,500 and 640,000 dots per square inch, preferably between 10,000 and 160,000. This corresponds to a linear resolution of between 50 and 800 dpi or dots per inch and 100 and 400 dpi or dots per inch respectively.
  • the appropriate area unit might be a square with a side of 2.54 cm.
  • This resolution value can also be expressed in "dpsi” or number of dots per square inch, which is derived from the unit of measurement dpi or "dots per inch” or “dots per inch”, commonly used to define the resolution of a printer or scanner.
  • the number of grains present per surface unit of the surface of the decorated composite is linked to the resolution of the device used to create the decoration on the gliding board, since the printing of the decoration is carried out with grains at the solid state, which cannot pass either to the liquid state, or to the gaseous state. Consequently, there is no diffusion of the grains in the resin, which contributes to the clean appearance of the decoration.
  • the ratio of the surface occupied by the grains to a unit surface is between 20 and 75%, advantageously between 25% and 50%.
  • This coverage ratio guarantees sufficient maintenance of the grains within the surface layer of hardened resin as well as good protection of the grains against external attacks.
  • the higher the coverage ratio the more the color is concentrated and appears with more intensity and contrast.
  • the ink grains are more firmly embedded when this ratio does not exceed a maximum value.
  • an ink grain has a diameter, or generally a larger dimension, of between 10 and 100 ⁇ m. These dimensions are chosen so that the thickness of the grain is ideally smaller than the supernatant resin thickness, in order to be correctly encompassed by the resin. The diameter is also chosen so that the grain is large enough to be correctly distinguished through the resin layer. Furthermore, the dimensions are also chosen to guarantee the aesthetic appearance of the decor and to obtain the best possible resolution within the limits of the constraints mentioned above.

  • the pattern covers the upper face of the gliding board.
  • the pattern is not limited to the composite material upper of the board, but it can also cover the side surfaces of the composite material of the board, which helps improve the overall aesthetic appearance.

  • the upper face of the composite material 15 is visible and therefore appears decorated.
  • a composite material 15 is typically formed of a fibrous layer 14 of glass, carbon, basalt or natural fibers, long or short, unidirectional or oriented or even consisting of a nonwoven, for example based on of polyester.
  • the fibrous layer 14 is impregnated with thermosetting resin 13 , for example an epoxy resin, or thermoplastic, such as a polyamide resin.
  • the resin 13 has a supernatant portion above the fibrous layer 14. This supernatant portion of resin 13 has a thickness of a few micrometers.
