Abstract

This is a new method decorating composites. A decorated complex is assembled with a reinforcing structure. This is based on a resin flowing under heat in a later cycle of hot pressing. There are at least two stages to the process. During the first, the decoration is transferred using the ink sublimation printing onto the first face (100) of a layer of transparent or translucent plastic material (1). In the second, novel stage a collage film (3) is adhered under heat and pressure to the assembly, onto the first face (100). This comprises a contrasting metal or metal alloy sheet (5). A mesh (4) may be placed between the contrast sheet (5) and the first face (100). Preferred materials of construction include aluminium and ionomeric polyolefin. Glass fibre reinforcement is included.

Description

L'invention concerne un nouveau procédé de décoration d'un article composite. Elle se rapporte plus particulièrement aux articles se présentant sous la forme de stratifiés regroupant différents matériaux plastiques et composites tels que les skis en général, les surfs, les planches à roulettes, certains composants pour cycle et autres objets de nature similaire.The invention relates to a new method of decorating a composite article. It relates more particularly to articles in the form of laminates grouping together different plastic and composite materials such as skis in general, surfboards, skateboards, some components for cycle and other similar objects.

La sublimation est une technique bien adaptée pour la décoration des skis. Elle permet d'utiliser de nombreux supports plastiques différents et d'imprimer des motifs quelconques sans qu'il soit nécessaire de soumettre le support à une opération préliminaire de préparation spécifique. Le principe de transfert consiste à faire évaporer des encres contenues sur un papier support sous forme d'extraits secs par application de chaleur et de pression contre le support à décorer. Le procédé est propre, rapide et sans émanation de vapeurs ou de solvants nocifs.Sublimation is a technique well suited for decoration of skis. It allows to use many different plastic supports and print patterns any without the need to submit the support to a preliminary specific preparation operation. The transfer principle consists in evaporating inks contained on a backing paper in the form of dry extracts by application of heat and pressure against the support to decorate. The process is clean, fast and without emanation from harmful vapors or solvents.

Le support décoré obtenu peut être solidarisé à une feuille de contraste par un film de collage pour constituer un complexe destiné à être assemblé avec une structure de renfort d'un article à base de résine fluable à chaud, lors d'un cycle de pressage à chaud.The decorated support obtained can be secured to a contrast sheet with a bonding film to form a complex intended to be assembled with a reinforcing structure of an article based on hot-melt resin during a cycle hot pressing.

Un procédé utilisant cette technique est exposé dans la demande française non publiée n° 95 13758. Il consiste à effectuer le transfert d'un décor par la méthode d'impression d'encre(s) sublimable(s) sur une première face d'une couche de matière plastique transparente ou translucide, puis à coller à chaud et sous pression sur la première face ainsi décorée une feuille de contraste.A method using this technique is described in the unpublished French application n ° 95 13758. It consists of transfer a decoration using the printing method sublimable ink (s) on a first face of a layer of transparent or translucent plastic, then stick to hot and pressurized on the first side thus decorated a contrast sheet.

Ce procédé est efficace et permet d'obtenir un complexe dont la décoration est régulière et bien définie.This process is effective and makes it possible to obtain a complex whose decoration is regular and well defined.

Pour obtenir l'article à l'état fini, le complexe est pressé à chaud sur la structure de renfort à une température et à une pression plus élevées que la température et la pression nécessaires pour la réalisation du complexe. Dans les cas où la feuille de contraste est une couche de fibre sèche naturelle ou synthétique, le fluage du film de collage est évité car la fibre sèche absorbe une partie du matériau thermoplastique en fusion en raison de sa porosité. La décoration du complexe reste bien définie.To obtain the article in the finished state, the complex is hot pressed on the reinforcement structure at a temperature and at higher pressure than the temperature and the pressure necessary for the realization of the complex. In the case where the contrast sheet is a layer of dry fiber natural or synthetic, the creep of the bonding film is avoided because the dry fiber absorbs part of the material thermoplastic in fusion due to its porosity. The decoration of the complex remains well defined.

Par contre, dans les cas où la feuille de contraste est faite en matériau non absorbant, comme un métal ou un alliage métallique, l'absorption de matériau thermoplastique ne se fait pas. Il s'ensuit que le film de collage flue. Le fluage se traduit par des déplacements de particules de la matière constitutive du film de collage, dans toute direction sensiblement parallèle à la feuille de contraste du complexe. Ainsi le film de collage se déforme de façon aléatoire, et les encres, qui ont migré dans le film à cause des élévations de température et de pression nécessaires au collage, se déplacent avec le fluage du film. Il s'ensuit que la qualité de la décoration est réduite car sa définition est altérée.However, in cases where the contrast sheet is made of non-absorbent material, such as metal or alloy metallic, absorption of thermoplastic material is not don't. It follows that the collage film flows. Creep results in displacements of particles of matter constituting the collage film, in any direction substantially parallel to the contrast sheet of the complex. Thus the collage film deforms randomly, and the inks, which migrated into the film due to the elevations of temperature and pressure required for bonding, move with the creep of the film. It follows that the quality decoration is reduced because its definition is altered.

L'invention a pour but de remédier aux inconvénients ci-avant explicités.The object of the invention is to remedy the above drawbacks clarified.

Pour ce faire, l'invention propose un procédé de décoration d'un article composite comprenant la préparation d'un complexe décoré pour être assemblé avec une structure de renfort de l'article à base de résine fluable à chaud lors d'un cycle ultérieur de pressage à chaud, le procédé comprenant au moins deux cycles, un premier cycle au cours duquel on effectue le transfert d'un décor par la méthode d'impression d'encre(s) sublimable(s) sur la première face d'une couche de matière plastique transparente ou translucide, et un second cycle.To do this, the invention proposes a method of decoration of a composite article including preparation of a complex decorated to be assembled with a structure of reinforcement of the article based on hot-melt resin during of a subsequent hot pressing cycle, the process comprising at least two cycles, a first cycle during from which the decoration is transferred by the method printing sublimable ink (s) on the first side a transparent or translucent plastic layer, and a second cycle.

Le procédé selon l'invention est caractérisé en ce qu'on procède dans le second cycle au moyen d'un film de collage à l'assemblage à chaud et sous pression sur la première face ainsi décorée, d'une feuille de contraste en matériau choisi parmi le groupe constitué par les métaux ou les alliages métalliques, et en ce que, dans une étape préalable à l'assemblage de la feuille de contraste sur la première face, on dispose un treillis entre la feuille de contraste et la première face. Il s'ensuit que le fluage du film de collage est évité lors du cycle de pressage à chaud, et que les encres restent à leur place car la matière constitutive du film de collage est emprisonnée dans les mailles du treillis. L'avantage est que la qualité de la décoration est bonne car sa définition est stable.The method according to the invention is characterized in that proceeds in the second cycle by means of a bonding film to hot assembly and pressure on the first side thus decorated, with a contrast sheet of selected material among the group consisting of metals or alloys metallic, and in that, in a step prior to assembling the contrast sheet on the first side, there is a lattice between the contrast sheet and the first side. It follows that the creep of the bonding film is avoided during the hot pressing cycle, and that the inks remain in their place because the material of the film collage is trapped in the mesh of the trellis. The advantage is that the quality of the decoration is good because its definition is stable.

Le procédé selon l'invention est également caractérisé en ce que la feuille de contraste est une feuille aluminium non anodisée recouverte sur chaque face d'une pellicule d'un copolymère d'oléfine du type ionomère.The method according to the invention is also characterized in what the contrast sheet is an aluminum sheet not anodized covered on each side with a film of ionomer type olefin copolymer.

La pellicule sert d'interface de collage et rend l'aluminium compatible au collage avec la plupart des substrats avec lesquels il est destiné à adhérer. Elle sert aussi de protection contre une oxydation de la feuille d'aluminium lors du stockage de celle-ci.The film acts as a bonding interface and makes aluminum compatible with bonding with most substrates with which it is intended to adhere. She serves also protective against oxidation of the leaf aluminum during storage.

Le procédé selon l'invention est caractérisé encore en ce qu'on dispose une nappe textile à base de fibres non tissées au contact de la feuille de contraste du côté de la feuille de contraste opposé au côté au contact duquel se trouve le treillis. La nappe textile à base de fibres non tissées atténue les déformations de la feuille de contraste liées à la présence du treillis.The method according to the invention is further characterized in that that we have a textile tablecloth based on non-woven fibers in contact with the contrast sheet on the side of the contrast opposite to the side in contact with which the trellis. The textile tablecloth based on non-woven fibers attenuates the deformations of the contrast sheet linked to the presence of the trellis.

Le procédé selon l'invention est caractérisé également en ce qu'un film de collage est disposé entre la feuille de contraste et la nappe textile à base de fibres non tissées. Le film permet une meilleure adhérence entre la feuille de contraste et la nappe textile.The method according to the invention is also characterized in a bonding film is placed between the sheet of contrast and the textile tablecloth based on non-woven fibers. The film allows better adhesion between the sheet of contrast and the textile tablecloth.

Le procédé selon l'invention est caractérisé encore par le fait que le treillis est un agencement de cordelettes en fibres de verre formant une grille à ouvertures carrées. Une telle structure de treillis est facile à fabriquer.The process according to the invention is further characterized by the makes the trellis an arrangement of cords in glass fibers forming a grid with square openings. A such a trellis structure is easy to manufacture.

Le procédé selon l'invention est caractérisé enfin en ce que la couche de matière plastique transparente ou translucide, le premier film de collage, le treillis, la feuille de contraste, le second film de collage, et la nappe textile à base de fibres non tissées, sont solidarisés ensemble au cours d'une seule opération. La fabrication est donc rapide et les coûts sont minimisés.The method according to the invention is finally characterized in that that the transparent plastic layer or translucent, the first collage film, the trellis, the contrast sheet, second collage film, and tablecloth textile based on non-woven fibers, are joined together in one operation. The manufacturing is therefore fast and costs are minimized.

L'invention se rapporte également à un complexe de décoration destiné à être assemblé avec une structure de renfort à base de reste fluable à chaud d'un article composite, ledit complexe comprenant une couche de matière plastique transparente dont une première face porte un décor obtenu par la méthode d'impression d'encre(s) sublimable(s), caractérisé par le fait qu'une feuille de contraste qui recouvre la première face de la couche plastique transparente est assemblée sur la face de la couche plastique au moyen d'un film de collage, en ce que la feuille de contraste est choisie parmi le groupe constitué par les métaux ou les alliages métalliques, et en ce qu'un treillis est disposé entre la feuille de contraste et la première face dans une étape préalable à l'assemblage de la feuille de contraste sur la face interne.The invention also relates to a complex of decoration intended to be assembled with a structure of reinforcement based on a hot-melt remainder of an article composite, said complex comprising a layer of material transparent plastic with a first side decorated obtained by the printing method of sublimable ink (s), characterized by the fact that a contrast sheet which covers the first side with the transparent plastic layer is assembled on the face of the plastic layer by means of a collage film, in that the contrast sheet is chosen among the group consisting of metals or alloys metal, and in that a trellis is arranged between the contrast sheet and the first side in one step prior to assembling the contrast sheet on the internal face.

Le complexe selon l'invention est également caractérisé par le fait qu'une nappe textile à base de fibres non tissées est disposée au contact de la feuille de contraste du côté de la feuille de contraste opposé au côté au contact duquel se trouve le treillis, et par le fait qu'un film de collage est disposé entre la feuille de contraste et la nappe textile à base de fibres non tissées.The complex according to the invention is also characterized by the fact that a textile sheet based on non-woven fibers is arranged in contact with the contrast sheet on the side of the contrast sheet opposite the side in contact with which finds the trellis, and by the fact that a bonding film is placed between the contrast sheet and the textile sheet to base of nonwoven fibers.

L'invention se rapporte, enfin, à un article composite du type ski ou surf des neiges muni d'un complexe de décoration préalablement décrit.The invention relates, finally, to a composite article of the ski or snowboard type with a decoration complex previously described.

La réalisation du procédé selon l'invention requiert tout d'abord l'utilisation d'une feuille plastique monocouche 1 en matériau transparent ou translucide ; cette feuille sera dénommée "couche transparente" dans la description ci-après. Carrying out the method according to the invention requires everything first use of a single layer plastic sheet 1 in transparent or translucent material; this sheet will called "transparent layer" in the description below.

Comme le montre la figure 1 on procède, dans une première étape, à une impression d'un décor par transfert de colorants sublimables sur une face 100 de la couche 1.As shown in Figure 1 we proceed, in a first step, to an impression of a decoration by transfer of dyes sublimable on one side 100 of layer 1.

Cette face 100 est destinée à constituer le côté interne de la couche transparente dans le complexe ; par opposition à la face opposée 101 qui est le côté externe. Le motif de décoration à imprimer est de façon connue en soi contenu dans une feuille de papier support 2 qui est appliquée sous une pression P à une température T pendant un temps t contre la face 100 de la couche transparente. La couche transparente peut être choisie parmi les matières plastiques sublimables de Polyamides tels que les PA11, PA12, PA6.3, PA6.6, etc, les Polycarbonates, les ABS (Acrylonitrile Butadiène Styrène), les AS (Acrylonitrile Styrène) transparents mélangés à un TPU (Elastomère thermoplastique uréthane), les Polyéthylènes Téréphtalates (PET).This face 100 is intended to constitute the internal side transparent layer in the complex; as opposed to the opposite face 101 which is the outer side. The reason for decoration to be printed is in a manner known per se a sheet of backing paper 2 which is applied under a pressure P at a temperature T for a time t against the face 100 of the transparent layer.

L'épaisseur de la couche transparente est comprise entre 0,2 et 1,1 mm. La sublimation est opérée à une température comprise entre 160 et 180°C, et à une pression de 1 à 3 bars pendant un temps compris entre 1mn30sec, et 4mn environ. La profondeur du front de migration des encres au travers de la couche transparente du côté interne est de l'ordre ou légèrement supérieur à 0,20 mm.The thickness of the transparent layer is between 0.2 and 1.1 mm. Sublimation is performed at a temperature between 160 and 180 ° C, and at a pressure of 1 to 3 bars for a time between 1mn30sec, and about 4mn. The depth of the ink migration front across the transparent layer on the inner side is around or slightly greater than 0.20 mm.

Au cours d'une seconde étape montrée à la figure 2, on effectue le rapprochement de la couche transparente 1 avec un film solide de collage 3, un treillis 4 et une couche de contraste 5. Le film de collage 3 est mis en contact avec la face prédécorée 100, le treillis 4 est mis en contact avec le film de collage 3 du côté du film 3 opposé au côté en contact avec la couche transparente 1, et enfin la couche de contraste 5 est mise en contact avec le treillis 4 du côté du treillis 4 opposé au côté en contact avec le film 3.In a second step shown in Figure 2, we reconciles transparent layer 1 with a solid bonding film 3, a trellis 4 and a layer of contrast 5. The bonding film 3 is brought into contact with the predecorated face 100, the trellis 4 is brought into contact with the bonding film 3 on the side of film 3 opposite the contacting side with the transparent layer 1, and finally the contrast layer 5 is brought into contact with the trellis 4 on the side of the trellis 4 opposite the side in contact with the film 3.

On procède ensuite à une phase de plaquage proprement dit par augmentation de pression et température jusqu'au point de ramollissement au moins du film, afin d'obtenir l'adhésion de la couche transparente 1 avec la couche de contraste 5 à travers le treillis 4.We then proceed to an actual plating phase by increasing pressure and temperature to the point of softening at least of the film, in order to obtain the adhesion of the transparent layer 1 with the contrast layer 5 to through the trellis 4.

Dans l'exemple illustré, le film de collage 3 est choisi pour son pouvoir d'adhérence avec la couche transparente 1 et avec la couche de contraste 5. Il s'agit d'un film thermofusible de fine épaisseur comprise entre quelques microns et quelques dixièmes de millimètres, l'épaisseur préférée étant voisine de 50 microns.In the example illustrated, the bonding film 3 is chosen for its adhesion with the transparent layer 1 and with the contrast layer 5. This is a film thin hot melt between a few microns and a few tenths of a millimeter, the thickness preferred being close to 50 microns.

On peut avantageusement utiliser un film 3 à base de polymère ou copolymère greffé par action d'acide carboxylique ou d'anhydride d'acide carboxylique, par exemple par l'acide acrylique, par l'acide méthacrylique, ou par l'anhydride maléique.It is advantageous to use a film 3 based on polymer or copolymer grafted by action of carboxylic acid or carboxylic acid anhydride, for example by acid acrylic, methacrylic acid, or anhydride maleic.

Un tel film 3 peut notamment être réalisé en polyéthylène greffé, par exemple en polyéthylène greffé par l'anhydride maléique.Such a film 3 can in particular be made of polyethylene grafted, for example in polyethylene grafted with anhydride maleic.

Cette nature de film permet le collage de la plupart des matériaux sublimables constituant la couche transparente 1 cités précédemment avec la couche de contraste 5.This type of film allows the bonding of most sublimable materials constituting the transparent layer 1 cited above with the contrast layer 5.

Mais le film 3 peut aussi être constitué d'un copolymère d'éthylène et d'acétate de vinyle (EVA), greffé par action d'acide carboxylique ou d'anhydride d'acide carboxylique.But the film 3 can also consist of a copolymer ethylene and vinyl acetate (EVA), grafted by action carboxylic acid or carboxylic acid anhydride.

Le treillis 4 est une structure alvéolée représentée sur les figures sous la forme d'un filet souple à mailles carrées. La trame du filet est formée par des cordelettes superposées représentées en coupe à la figure 2 par des cercles dans l'épaisseur du treillis 4.The trellis 4 is a honeycomb structure shown on the figures in the form of a flexible square mesh net. The net frame is formed by superimposed cords represented in section in Figure 2 by circles in the thickness of the mesh 4.

Les cordelettes sont réalisées de préférence en fibres telles que des fibres de verre, de carbone ou autre. L'épaisseur du treillis peut être comprise entre quelques dixièmes de microns et quelques dixièmes de millimètres, l'épaisseur préférée étant voisine de 0.1 mm. La largeur des mailles peut être comprise entre quelques dixièmes de millimètres et quelques millimètres, la largeur préférée étant de l'ordre de 2 ou 3 mm.The cords are preferably made of fibers such as glass, carbon or other fibers. The thickness of the trellis can be between a few tenths of a micron and a few tenths of a millimeter, the preferred thickness being close to 0.1 mm. The width of meshes can be between a few tenths of millimeters and a few millimeters, the preferred width being of the order of 2 or 3 mm.

La couche de contraste 5 est une feuille d'aluminium non anodisée de fine épaisseur 51 recouverte sur chaque face d'une pellicule d'un copolymère d'oléfine du type ionomère (nom commercial SURLYN®).The contrast layer 5 is a sheet of aluminum not thin anodized 51 covered on each side with film of an ionomer type olefin copolymer (name SURLYN®).

L'épaisseur de la feuille d'aluminium est comprise entre 15 et 200 µm et l'épaisseur de chaque pellicule comprise entre 10 et 50 µm. The thickness of the aluminum foil is between 15 and 200 µm and the thickness of each film between 10 and 50 µm.

Dans l'exemple illustré, l'utilisation d'un film 3 en polyéthylène greffé à l'anhydride maléique permet le collage d'une couche transparente 1 en polyamide sur une couche de contraste 5 aluminium traité ionomère à travers les mailles du filet. Le treillis 4 est donc emprisonné entre la couche transparente 1 et la couche de contraste 5.In the example illustrated, the use of a film 3 in polyethylene grafted with maleic anhydride allows bonding of a transparent layer 1 of polyamide on a layer of contrast 5 ionomer treated aluminum through the meshes of the net. The trellis 4 is therefore trapped between the layer transparent 1 and the contrast layer 5.

On provoque l'adhésion du film 3 sur la couche 1 par augmentation de la température jusqu'à une valeur supérieure ou égale à 160°C, et en plaquant à chaud, par calandrage ou pressage, le film 3 contre le premier élément 1 pour assurer leur solidarisation l'un à l'autre.The adhesion of the film 3 is caused on the layer 1 by temperature increase to a higher value or equal to 160 ° C, and by hot pressing, by calendering or pressing, the film 3 against the first element 1 to ensure their joining together.

Dans l'exemple illustré, on procède à l'assemblage des différentes couches 1, 3, 4, 5 dans le cadre d'un seul cycle de chauffage et de mise en pression. Sur le plan mécanique, le cycle de chauffage provoque un ramollissement du film de collage 3. Le treillis 4, par les cordelettes formant les mailles, évite à la matière constitutive du film de collage 3 de fluer dans une direction sensiblement parallèle au côté interne 100 de la feuille 1. Le seul sens de fluage possible pour le film 3 est un sens de traversée du treillis 4, de façon que le film 3 soit au contact à la fois de la couche 1 et de la couche 5.In the example illustrated, the assembly of the different layers 1, 3, 4, 5 in a single cycle heating and pressurizing. Mechanically, the heating cycle causes the film to soften collage 3. The trellis 4, by the cords forming the mesh, avoids the material of the bonding film 3 to flow in a direction substantially parallel to the side internal 100 of sheet 1. The only direction of creep possible for film 3 is a direction of crossing the trellis 4, of so that film 3 is in contact with both layer 1 and layer 5.

Il s'ensuit qu'un colorant qui a pu migrer dans le film 3, lors des montées en température et pression de la seconde étape, ne peut être déplacé dans un sens sensiblement parallèle au côté interne 100 de la feuille 1.It follows that a dye that may have migrated into film 3, during temperature and pressure increases of the second step, can only be moved in one direction substantially parallel to the inner side 100 of the sheet 1.

C'est pourquoi la précision du décor initial n'est pas altérée par un fluage du film de collage 3.This is why the precision of the initial decoration is not altered by creep of the bonding film 3.

Comme le montrent les figures 2, 3, 4 et 5, l'invention prévoit également l'emploi d'un film de collage 6 pour solidariser une couche de fibres non tissées 7 à la couche de contraste 5 pendant la seconde étape ou lors d'une étape ultérieure.As shown in Figures 2, 3, 4 and 5, the invention also provides for the use of a bonding film 6 for securing a layer of nonwoven fibers 7 to the layer of contrast 5 during the second stage or during a stage later.

De préférence, le film 6 et la couche 7 sont assemblés avec les couches 1, 3, 4, 5 dans le cadre du seul cycle de chauffage et de mise en pression de la seconde étape. Le film 6 est similaire au film 3, et la couche 7 est faite à partir de fibres telles que les fibres de verre, de carbone ou autre dans des épaisseurs comprises entre 0,05 et 1 mm. La couche 7 sert à atténuer des déformations apparaissant dans la couche de contraste 5 pendant la seconde étape de par la présence du treillis 4.Preferably, the film 6 and the layer 7 are assembled with layers 1, 3, 4, 5 as part of the single cycle heating and pressurization of the second stage. The film 6 is similar to film 3, and layer 7 is made from fibers such as glass, carbon or other fibers in thicknesses between 0.05 and 1 mm. Layer 7 used to reduce deformations appearing in the layer contrast 5 during the second stage due to the presence of trellis 4.

En effet, les cordelettes du treillis 4 peuvent provoquer localement des déformations de la couche de contraste 5 dans les cas où l'épaisseur de la couche 51 est trop faible, c'est-à-dire comprise entre 15 et 100 µm. En ajoutant la couche 7, les déformations de la couche 5 sont réduites et n'altèrent pas la structure de la couche 5 sur le plan de la résistance mécanique ou de l'effet visuel perçu à travers la couche 1.Indeed, the cords of the mesh 4 can cause locally deformations of the contrast layer 5 in the cases where the thickness of the layer 51 is too small, that is to say between 15 and 100 µm. By adding layer 7, the deformations of layer 5 are reduced and do not alter not the structure of layer 5 in terms of resistance mechanical or visual effect perceived through layer 1.

Dans l'exemple illustré, on a procédé à l'assemblage des différentes couches 1, 3, 4, 5, 6, 7 en une seule opération.In the example illustrated, the assembly of the different layers 1, 3, 4, 5, 6, 7 in one operation.

Bien entendu, il est envisageable de décomposer cette opération en une série d'opérations intermédiaires. En particulier, on peut procéder au plaquage d'un film de collage sur une couche, puis procéder au plaquage d'une autre couche sur l'autre côté du film de collage.Of course, it is possible to decompose this operation in a series of intermediate operations. In particular, we can proceed with the plating of a bonding film on one layer, then proceed to plating another layer on the other side of the collage film.

Le complexe formé, montré à la figure 3, est ensuite prêt à l'emploi pour servir au recouvrement d'un article composite à décorer.The complex formed, shown in Figure 3, is then ready for use in covering a composite article to decorate.

Par article composite, on entend essentiellement tout objet stratifié possédant une structure de renfort. On pense en particulier, aux skis, surfs des neiges, planches à roulette, etc.By composite article is meant essentially everything laminate object having a reinforcing structure. It is believed in particular, on skis, snowboards, snowboards roulette, etc.

La figure 4 montre schématiquement la coupe d'un ski qui comprend un complexe obtenu selon le procédé de l'invention.Figure 4 shows schematically the section of a ski which comprises a complex obtained according to the method of the invention.

La solidarisation du complexe avec le reste de la structure du ski peut être faite dans le cadre de procédés très différents. Dans tous les cas, on procède généralement à un cycle de pressage à chaud avec la structure de renfort 8 du ski à base de résine thermofluable. Cette structure de renfort 8 peut notamment être constituée d'une nappe textile de renfort pré-imprégnée d'une résine thermodurcissable ou d'une résine thermoplastique.The joining of the complex with the rest of the ski structure can be made as part of processes very different. In all cases, one generally proceeds to a hot pressing cycle with the reinforcement structure 8 of the ski based on thermofluable resin. This reinforcement structure 8 may in particular consist of a textile sheet of reinforcement pre-impregnated with a thermosetting resin or a thermoplastic resin.

On peut notamment utiliser une nappe textile de renfort à base de fibres tissées ou non tissées en verre, en carbone ou en polyaramide, imprégnée d'une résine thermodurcissable humide ou partiellement réticulée choisie dans le groupe constitué par le polyester, les époxydes, les polyuréthanes. One can in particular use a textile reinforcement ply to base of woven or non-woven fibers of glass, carbon or made of polyaramid, impregnated with a thermosetting resin wet or partially crosslinked chosen from the group consisting of polyester, epoxies, polyurethanes.

En alternative, on peut utiliser une nappe textile de renfort à base de fibres tissées ou non tissées en verre ou en carbone imprégnée d'une résine thermoplastique choisie dans le groupe constitué par les polyamides, les polycarbonates, les PEI (Polyéther Imide).Alternatively, a textile tablecloth can be used. reinforcement based on woven or non-woven fibers of glass or carbon impregnated with a thermoplastic resin chosen from the group consisting of polyamides, polycarbonates, PEI (Polyether Imide).

L'invention n'est pas limitée au mode de réalisation ainsi décrit, et comprend tous les équivalents techniques pouvant entrer dans l'étendue des revendications qui vont suivre.The invention is not limited to the embodiment thus describes, and includes all technical equivalents that can to enter into the scope of the claims which will follow.

Notamment, on peut prévoir d'utiliser tout métal ou alliage métallique pour fabriquer la couche de contraste 5.In particular, one can plan to use any metal or metal alloy to make the contrast layer 5.

On peut aussi prévoir toute structure pour réaliser un treillis 4 qui peut comporter des mailles de différentes formes comme des triangles, des hexagones, divers polygones réguliers ou irréguliers.We can also provide any structure to achieve a lattice 4 which may include meshes of different shapes like triangles, hexagons, various polygons regular or irregular.

Le treillis 4 pourrait être une couche uniforme percée par des trous circulaires ou non circulaires.The mesh 4 could be a uniform layer pierced by circular or non-circular holes.
