Definitions
- the present invention relates to a snowboard on snow comprising a textile reinforcing element.
- This is for example a ski, a monoski, a surf, etc.
- a snowboard on snow usually has a lower set with a sole and possibly edges as well than a reinforcing element which can be fibrous or metallic.
- a reinforcing element which can be fibrous or metallic.
- On this lower set is placed a rigid core that can be realized in various materials. At the height of this core are possibly found on the side edges of the gliding board, reinforcing elements called songs.
- an upper assembly comprising a layer of fibrous or metallic reinforcement and an outer leaf complements the structure of this gliding board.
- the present invention relates more particularly to boards gliding on snow for which the reinforcements used are textile reinforcements.
- the textile reinforcements used generally comprise a tablecloth yarns extending in a direction and a web of yarns extending into another direction. These two directions may be perpendicular but they can also have between them an angle different from 90 °.
- the threads used in this textile reinforcement are generally, but not exclusively, made from glass fibers.
- This polyester veil is for example a nonwoven which is assembled reinforcement plies by binding or sewing.
- a disadvantage of these textile reinforcements is their complexity which involves a relatively high cost price. Moreover, when the reinforcement is glued and that the structure of the gliding board is solicited mechanically, we can cause delamination at the interface between the polyester and the glass or inside the non-woven layer in polyester.
- US-A-5 584 496 discloses a gliding board comprising composite ropes composed of fibers of different natures.
- a board of slide on snow includes at least one textile reinforcement fixed by gluing on a core or other rigid elements such as a metal reinforcement by example, in which the structure of the textile reinforcement is simplified in order to reduce the cost.
- this textile reinforcement will present, at equal performance, a lower density than known textile reinforcements.
- This textile reinforcement will preferably have a better adhesion to the core, or other rigid element, of the gliding board in order to avoid the delamination problems.
- the snowboarding board that she proposes is a board comprising at least one fibrous reinforcement.
- At least one fibrous reinforcement less on an outer face of compound composite voluminous yarns at least two fibers of different natures.
- a voluminized wire is a wire that has been made in such a way that it a relatively large volume in relation to the volume of fibers that constitute it. During its manufacture, we gave the swelling to this thread.
- Resin nesting nests are thus produced which make it possible to obtain good qualities of collage by removing the synthetic intermediate layer. By the way removal of the latter, the effects of shear and damping provided by it are also removed and the board slides as well obtained is less amortized and more lively.
- the voluminized yarns preferably contain reinforcement and adhesion fibers.
- the voluminized wires on the one hand allow a good collage by their structure and by their composition and on the other hand have good mechanical strength thanks to the reinforcing fibers.
- the reinforcing fibers of the voluminized yarns are, for example, glass, carbon or aramid while adhesion fibers are as for them for example polyester.
- the presence of polyester in the son, and having voluminized wires, can achieve a good bonding by obtaining a good adhesion and a good grip.
- other fibers can be used. Those indicated above allow however to obtain a good mechanical resistance for a cost price acceptable.
- the voluminized wires of the fiber reinforcement are composed of glass fibers and polyester fibers, the proportion of polyester fibers being at least 15% on the surface.
- the voluminized threads are woven and constitute the weft threads fabric obtained in a preferred embodiment.
- the voluminized yarns are, for example, textured yarns obtained by simultaneous texturing of a reinforcing thread and a polyester thread. This method of obtaining voluminized wire is well adapted for the wire obtained serve as a reservoir for the glue used and makes a good snap on the core or other rigid element.
- a fibrous reinforcement advantageously comprises, besides a web of composite voluminous threads, a second ply of reinforcing threads.
- This second sheet of son comprises for example aligned rovings son parallel to each other. It can be connected to the wire cloth voluminized by binding.
- the threads of the second ply can be made from fibers selected from the group consisting of glass fibers, carbon and aramid fibers. Of course, this list is not comprehensive.
- FIG. 1 is a cross-sectional view of a ski 2. recognize in this figure a lower assembly comprising a sole 4, edges 6 and a lower reinforcement 8. This ski also comprises a shell 10, a metal upper reinforcement 13 and an upper reinforcement 12 fibrous. The lower reinforcements 8 and upper 12 are textile reinforcements glued with an epoxy resin on a core 14. These reinforcements are described in more detail below.
- Each reinforcement 8, 12 is a textile comprising on the one hand a layer of fabric 16 and secondly a ply 18 of rovings son. Layer of fabric 16 and the ply of threads 18 are connected by means of a binding thread 20. The cloth layer 16 is intended to come against either the core 14 or against the metal reinforcement 13.
- the fabric layer 16 comprises warp yarns 22 and threads frame 24
- the warp yarns are for example made using fiber from glass and are silionne threads of 34 tex.
- the weft yarns 24 are bicomponent and textured yarns, obtained by simultaneous texturing of a glass roving wire of 200 tex and polyester thread of 110 tex. This gives a textured glass / polyester thread of 350 tex.
- FIG. 2 represents a weave in which each weft yarn 24 passes successively under a warp yarn 22 and then on a warp yarn 22, etc. We can of course have a different weave.
- the warp threads 22 are preferably spaced apart from each other. Their main function is to ensure the cohesion between the weft yarns 24.
- the ply 18 of rovings son consists of son rovings of glass of 1200 tex arranged next to each other to form a sheet with a density of 720 g / m 2 . These rovings son extend in the same direction as the warp son 22 of the fabric layer 16.
- the fabric layer 16 and the ply 18 of rovings are assembled by binding. This binding operation can be performed at the same time time as the weaving of the cloth layer 16.
- the weft yarns 24 fulfill the interface function during the bonding reinforcements 8, 12 on the core 14 and on the metal reinforcement 13. for example comprises 50% polyester surface. It is estimated that minimal polyester proportion to allow good adhesion is 15% on the surface. The fact that the weft yarns 24 are voluminized allows to have a good attachment of the layer of fabric 16 on the core 14 and the metal reinforcement 13. In addition, this allows the fabric layer 16 to act as a reservoir for the glue, for example epoxy resin.
- the rovings son of the sheet 18 are arranged longitudinally in the ski 2.
- the weft son 24 are then arranged in the transverse direction.
- the angle between the rovings son of the ply 18 and the weft son 24 is not necessarily a right angle. Another angle is conceivable, for example 60 or 120 °.
- the reinforcement fabrics of the prior art comprised three layers: a first layer of rovings son equivalent to the tablecloth 18 described above, a fabric whose weft threads are rovings threads for to ensure a good resistance and whose son of chain are son to keep in place the weft threads, and a nonwoven web in polyester.
- the textile reinforcement described above has, for identical mechanical strength, a lower surface density and a lower cost price. Indeed, less polyester is needed to achieve the reinforcement of a ski according to the invention.
- the production process is simplified. The cost reduction is also due to a saving on raw materials, mainly polyester, but also on the resin epoxy thanks to a smaller glue reserve while remaining sufficient to ensure a good bond.
- the invention thus makes it possible to obtain a more resistant ski.
- the advantages of the reinforcement shown in the drawing described above make that the ski according to the invention is a ski lighter and more responsive.
- Another advantage of a ski according to the invention is that the reinforcements fibrous lower 8 and upper 12 are less hydrophilic than reinforcements of the prior art comprising a nonwoven. So there is less risk that water penetrates inside the ski and comes, by freezing, damaging ski.
- the invention does not apply only to a ski but can also apply to a monoski, a snowboard, etc.
- the reinforcing textile has been described by way of example. He ... not necessarily a layer of fabric. Voluminized wires used could be simply laid out in sheet as well as the wires of glass rovings described above.
- the reinforcing fibers may be glass fibers but other materials are possible.
- the reinforcing textile described has two layers. Generally, for a ski, we are actually looking for a reinforcement in two directions. However, we would not go beyond the scope of the invention using only one layer of reinforcement. This layer would then include voluminized wires made from polyester and reinforcing fibers. Similarly, we can also consider to use a reinforcement having more than two layers of reinforcing fibers.
