Definitions

  • the present invention relates to a ski and its manufacturing process.
  • a ski generally has one or more upper layers of decoration and protection against external aggressions, sometimes extending laterally to cover the edges of the ski.
  • the present invention aims to achieve an upper decoration and protection element, of a lower cost, resistant to external aggressions and to hot creep, compatible with the materials generally used in mechanical reinforcements and also making it possible to use all modern printing processes, such as sublimation for example.
  • the invention relates to a ski consisting of an upper decoration and protection sub-assembly characterized in that it comprises a lower layer, consisting of a copolymer of styrene and carboxylic acid or an anhydrous of carboxylic acid or an alloy of this copolymer, on which adheres at least one upper layer consisting of a polyamide.
  • the invention also relates to the method of manufacturing such a ski.
  • FIG. 1 shows in perspective a ski made according to the present invention.
  • This ski comprises, in a traditional manner, an upper face 1, a lower face 2 or sliding surface, two lateral faces 3 and 4, and a front end curved upwards, in the shape of a spatula 5.
  • a decoration 6, schematically represented is visible from the outside on the upper face 1 and the lateral faces 3 and 4.
  • FIG. 2 illustrates an example of skiing in an embodiment according to which there is shown an upper sub-assembly 7 for decoration and protection made up of two layers 71 and 72; one, lower 71, a copolymer of styrene and carboxylic acid or an anhydrous carboxylic acid; the other, upper 72, made of polyamide.
  • the lower layer 71 is an opaque plastic material with a density close to 1, and preferably consists of a copolymer of styrene and maleic anhydride. It can optionally be modified or loaded by any means well known to those skilled in the art so as to increase its mechanical characteristics. Thus, provision can be made for the lower layer 71 to consist of an alloy of a copolymer of styrene and maleic anhydride, and of an elastomer for example. In the type of fillers which may be suitable, mention may be made of green balls, green fiber, carbon fiber or the like.
  • This copolymer has very good adhesion capacities with the upper layer 72.
  • the polyamide which constitutes the latter is preferably chosen from polyamides 11. It is transparent, rigid and has good resistance to external conditions. It is, on the other hand, easily sublimable.
  • Each layer 71 and 72 has a thickness of between 0.1 and 1 mm approximately.
  • FIG. 3 represents a sectional view of the detailed structure of a ski according to another embodiment of the invention in which the upper decoration and protection assembly 7 extends laterally up to the level of the edges 8 and a a section whose shape is substantially that of an inverted U.
  • This construction has the advantage of being able to apply or extend the decoration on the lateral faces 3 and 4 of the ski.
  • the decoration and protection sub-assembly 7 is integral with an upper reinforcement layer of the mechanical sub-assembly 9 by means of a layer of adhesive, for example.
  • the mechanical sub-assembly 9 comprises an upper reinforcing layer 91 consisting of a textile sheet of reinforcement and a thermosetting matrix such as an epoxy, polyester or polyurethane resin or a thermoplastic matrix.
  • the matrix has excellent adhesion properties with the lower layer of copolymer of the decoration sub-assembly, which eliminates the need for an additional adhesive interface.
  • the lower mechanical sub-assembly 9 brings together all the elements necessary for the strength of the ski, including a sliding sole 94, generally made of polyethylene, edges 8, a lower reinforcement 93, a core 92, at least one upper reinforcement layer 91.
  • a sliding sole 94 generally made of polyethylene
  • edges 8 edges 8
  • a lower reinforcement 93 a core 92
  • at least one upper reinforcement layer 91 The example of the structure of FIG. 3 is in no way limiting and is given only by way of example.
  • the invention also resides in the method of manufacturing such a ski, consisting of assembling the upper decoration sub-assembly 7 to the lower mechanical sub-assembly 9 and comprises a prior step of manufacturing the decoration sub-assembly.
  • This step makes it possible to obtain adhesion of the upper layer 72 of polyamide, and the lower layer 71 of a copolymer of styrene and of carboxylic acid or an anhydrous of carboxylic acid.
  • the bilayer obtained meets the normally recognized bonding requirements of a laminate for the manufacture of a ski.
  • this preliminary manufacturing step includes a final decoration phase. This can be achieved by the sublimation process described by patent No. 87 13552 of the applicant for example.
  • the decoration sub-assembly thus formed is applied to the lower mechanical sub-assembly 9 and particularly to at least part of an upper reinforcing layer 91 of the sub-assembly.
  • the polymer layer 71 can extend laterally beyond the reinforcement by adhering to other elements, such as binders, edges, or the like.
  • the assembly step may preferably include an actual molding phase during which the various elements are subjected to high pressures and temperatures. Adhesion is particularly effective when the upper reinforcement layer consists of a textile sheet pre-impregnated with a resin matrix thermosetting, not fully crosslinked, or a matrix of thermoplastic resin.
  • Epoxy, polyester, or polyurethane resin matrices generally give the best results when used with a copolymer of styrene and maleic anhydride, modified or not. It is the molding operation which makes it possible to reactivate the final crosslinking and to cause adhesion in the case of a matrix of thermosetting resin.
  • the implementation of the molding operation can be different depending on the process; an example of a process for manufacturing a ski, the core of which is injected, is described in patent No. 89 15664 of the applicant.
  • the molding phase is not carried out when the elements of the mechanical sub-assembly are produced beforehand and then assembled by gluing.
