Abstract
Description
L'invention concerne un perfectionnement apporté aux armatures textiles utilisées pour la réalisation d'un matériau composite, c'est-à-dire d'articles à base de résine (polyester ou autres), armés d'une nappe textile de renforcement.The invention relates to an improvement made to reinforcements textiles used for the production of a composite material, i.e. resin-based articles (polyester or other), reinforced with a textile tablecloth reinforcement.
Elle a trait plus particulièrement à un perfectionnement apporté aux armatures faisant l'objet du FR-A-2 646 442 au nom du Demandeur, dont le contenu est intégré à la présente demande en tant que de besoin.It relates more particularly to an improvement brought to reinforcements which are the subject of FR-A-2 646 442 in the name of the Applicant, of which the content is integrated into the present request as necessary.
D'une manière générale, l'armature faisant l'objet du brevet précité est constituée par au moins deux couches de renfort textile proprement dites, disposées de part et d'autre d'une couche centrale donnant l'épaisseur dudit matériau et elle se caractérise en ce que ladite couche centrale est constituée par une nappe à base de fibres synthétiques, de titre unitaire élevé et qui ont reçu préalablement à leur mise sous forme de nappe un traitement leur communiquant une ondulation ou frisure permanente conduisant à la formation d'une nappe légère, épaisse et aérée. Avantageusement, les différentes couches sont liées entre elles par couture/tricotage.In general, the frame which is the subject of the aforementioned patent consists of at least two layers of textile reinforcement properly say, arranged on either side of a central layer giving the thickness of said material and it is characterized in that said layer central consists of a tablecloth based on synthetic fibers, of title high unit and which received prior to their formatting tablecloth a treatment communicating to them an undulation or crimp permanent leading to the formation of a light, thick and airy. Advantageously, the different layers are linked together by sewing / knitting.
Par ailleurs, les couches de renfort textile disposées de part et d'autre de la couche centrale donnant l'épaisseur, sont avantageusement constituées de mats fibreux éventuellement associés à d'autres renforts textiles. In addition, the textile reinforcement layers arranged on either side of the central layer giving the thickness, are advantageously consisting of fibrous mats possibly associated with other reinforcements textiles.
Les armatures réalisées conformément au brevet précité sont particulièrement adaptées pour être utilisées dans les techniques du moulage à la presse, du moulage par injection et du moulage sous vide.The reinforcements produced in accordance with the aforementioned patent are particularly suitable for use in the techniques of press molding, injection molding and vacuum molding.
Il a cependant été constaté que dans certaines applications, la liaison des différentes couches par couture/tricotage entraínait parfois des défauts d'aspect de surface, notamment du côté chainette que forment de telles liaisons.However, it has been found that in certain applications, the connection different layers by sewing / knitting sometimes resulted in surface appearance defects, especially on the chain side formed by such links.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, qu'il était possible, non seulement d'améliorer l'état de surface du matériau composite comportant une telle armature, mais également d'adapter certaines caractéristiques techniques telles que stabilité dimensionnelle du produit, possibilité de déformation .. , en fonction des applications dans lesquelles rentre un tel matériau.Now we have found, and this is what is the subject of the present invention, that it was possible not only to improve the surface finish of the composite material comprising such a reinforcement, but also to adapt certain technical characteristics such as stability dimension of the product, possibility of deformation, depending on the applications in which such a material fits.
D'une manière générale, le perfectionnement conforme à l'invention consiste, dans une armature du type faisant l'objet du brevet français précité et qui comporte donc au moins deux couches de renfort textile disposées de part et d'autre d'une couche centrale donnant l'épaisseur audit matériau, lesdites couches étant liées entre elles par couture/tricotage, à rapporter, au moins contre l'une des faces externes du complexe, un voile de fibres synthétiques, la liaison dudit voile étant réalisée soit par collage à l'extérieur du complexe, soit par l'intermédiaire des coutures liant les différentes couches entre elles. Generally speaking, further processing in accordance with the invention consists, in a frame of the type which is the subject of the patent aforementioned French and which therefore comprises at least two layers of reinforcement textile arranged on either side of a central layer giving the thickness of said material, said layers being linked together by sewing / knitting, to be brought back, at least against one of the external faces of the complex, a veil of synthetic fibers, the bond of said veil being produced either by bonding outside the complex, or through seams connecting the different layers together.
La nappe centrale est de préférence à base de fibres synthétiques de titre élevé et frisées d'une manière similaire au brevet précité, mais peut également être à base d'autres fibres grossières, par exemple de fibres végétales. Cette nappe centrale a de préférence un poids compris entre 150 g/m2 et 400 g/m2. En effet, pour un poids inférieur à 150 g/m2, le complexe manque de tenue et de régularité, alors qu'un poids supérieur à 400 g/m2 conduit à des produits d'épaisseur qui ne se justifient pas dans la pratique. L'épaisseur de cette nappe centrale est en général comprise entre 3 et environ 8 mm.The central ply is preferably based on synthetic fibers of high title and curly in a similar manner to the aforementioned patent, but may also be based on other coarse fibers, for example fibers vegetable. This central tablecloth preferably has a weight of between 150 g / m2 and 400 g / m2. Indeed, for a weight less than 150 g / m2, the complex lack of dress and regularity, while a weight greater than 400 g / m2 leads to thick products which are not justified in the practice. The thickness of this central ply is generally understood between 3 and about 8 mm.
Les couches de renfort textile disposées de part et d'autre de la couche centrale sont avantageusement constituées par un mat de verre, éventuellement renforcé par une grille textile, le poids de ces couches étant en général compris entre 300 et 600 g/m2.The textile reinforcement layers placed on either side of the layer central are advantageously constituted by a glass mat, possibly reinforced by a textile grid, the weight of these layers being generally between 300 and 600 g / m2.
De préférence, on utilisera un voile de fibres synthétiques ayant un grammage compris entre 50 et 150 g/m2, les fibres synthétiques entrant dans la réalisation d'un tel voile étant très fines, et ayant en général un titre compris entre 1 et 7 dtex, c'est-à-dire des fibres beaucoup plus fines que celles entrant dans la composition de l'armature proprement dite. Une telle finesse des fibres de surface permet d'avoir une très bonne homogénéité, favorisant la répartition de la résine lors du moulage. Par ailleurs, ces fibres de surface empêchent le marquage par les fibres grossières de la structure interne. Preferably, a veil of synthetic fibers having a grammage between 50 and 150 g / m2, synthetic fibers entering in the realization of such a veil being very thin, and generally having a titer between 1 and 7 dtex, i.e. much finer fibers than those used in the composition of the reinforcement itself. Such fineness of the surface fibers makes it possible to have a very good homogeneity, favoring the distribution of the resin during molding. By elsewhere, these surface fibers prevent marking by the fibers coarse internal structure.
L'invention et les avantages qu'elle apporte sera cependant mieux comprise grâce aux exemples de réalisation donnés ci-après à titre indicatif mais non limitatif, ces exemples étant illustrés par les figures 1 à 4 annexées correspondant à quatre types de produit réalisés conformément à l'invention.The invention and the advantages which it brings will however be better understood thanks to the exemplary embodiments given below by way of indicative but not limiting, these examples being illustrated by FIGS. 1 to 4 appended corresponding to four types of product produced according to the invention.
Les quatre produits réalisés conformément à l'invention comportent une structure de base réalisée conformément aux enseignements du FR-A-2 646 442 et qui comporte :
- une couche interne (1) constituée par une nappe non tissée, réalisée par cardage, à partir de fibres de polyester ayant un titre unitaire de 40 dtex et une longueur de coupe de 60 mm, les fibres ayant été préalablement frisées avant coupe de manière à présenter des ondulations permanentes (dans le cas présent 2,3 ondulations par centimètre) ; cette nappe pèse environ 250 g/m2 et a une épaisseur d'environ 5 mm ;
- deux nappes de renfort textile proprement dites (2,3) sont disposées de part et d'autre de la couche interne (1) précitée, ces nappes de renfort textile étant constituées toutes les deux par un mat de verre pesant 450 g/m2, obtenu par découpe de fibres de verre et nappage conventionnel par voie sèche; ces fibres de verre ont un titre d'au moins 25 tex, leur longueur de coupe étant de 50 mm.
- an inner layer (1) consisting of a nonwoven web, produced by carding, from polyester fibers having a unit titer of 40 dtex and a cutting length of 60 mm, the fibers having been crimped before cutting so as to have permanent undulations (in this case 2.3 undulations per centimeter); this sheet weighs approximately 250 g / m2 and has a thickness of approximately 5 mm;
- two textile reinforcement plies proper (2,3) are arranged on either side of the above-mentioned internal layer (1), these textile reinforcement plies being both constituted by a glass mat weighing 450 g / m2, obtained by cutting glass fibers and conventional coating by dry process; these glass fibers have a titer of at least 25 tex, their cutting length being 50 mm.
A cette structure de base, est associé, conformément à l'invention, au moins contre l'une des faces externes, un voile de fibres synthétiques désigné par la référence (4). Ce ou ces voiles (4) peuvent soit être collés à l'extérieur du complexe tricouches liés par couture/tricotage, soit être rapporté contre l'une ou l'autre des faces externes du complexe avant qu'elles ne soient liées par couture/tricotage. According to the invention, this basic structure is associated with the less against one of the external faces, a veil of synthetic fibers designated by reference (4). This or these sails (4) can either be glued to outside the complex three-layer linked by sewing / knitting, either be reported against one or other of the external faces of the complex before they are not linked by sewing / knitting.
Dans l'exemple de réalisation illustré à la figure 1, un seul voile (4) constitué de fibres de polyester ayant un titre compris entre 1 dtex et 7 dtex et pesant entre 50 g et 150 g/m2, est rapporté contre la couche de renfort externe (2), les ensembles des couches étant cousus au moyen d'un fil polyester ayant un titre de 176 dtex.In the exemplary embodiment illustrated in FIG. 1, a single web (4) made of polyester fibers having a count between 1 dtex and 7 dtex and weighing between 50 g and 150 g / m2, is applied against the layer of external reinforcement (2), the sets of layers being sewn using polyester yarn having a titer of 176 dtex.
Par rapport aux complexes réalisés conformément aux enseignements du FR-A-2 646 442 ne comportant pas de voile polyester, on obtient un meilleur état de surface lors de la réalisation du matériau composite. Par ailleurs, une telle structure possède une meilleure stabilité dimensionnelle et se déforme moins.Compared to complexes produced in accordance with lessons from FR-A-2 646 442 not comprising a polyester veil, a better surface condition is obtained during the production of the material composite. Furthermore, such a structure has better stability dimensional and less deformed.
La figure 2 illustre une forme de réalisation dans laquelle le même voile de polyester (4) est rapporté à l'extérieur du complexe (1,2,3) préalablement lié par couture/tricotage.Figure 2 illustrates an embodiment in which the same polyester veil (4) is added to the outside of the complex (1,2,3) previously linked by sewing / knitting.
Par rapport au matériau tel qu'illustré à la figure 1, on obtient un meilleur état de surface ainsi qu'une plus grande possibilité de déformation du produit.Compared to the material as illustrated in Figure 1, we obtain a better surface finish and greater possibility of deformation of the product.
Dans la forme de réalisation illustrée à la figure 3, deux voiles (4) sont associés de part et d'autre du complexe, l'un disposé contre la nappe (3) étant cousu, l'autre disposé contre la nappe (2) étant collé au dessus des coutures.In the embodiment illustrated in Figure 3, two sails (4) are associated on both sides of the complex, one placed against the tablecloth (3) being sewn, the other arranged against the tablecloth (2) being glued to the top seams.
Un tel produit permet d'obtenir un matériau composite présentant un excellent état de surface sur les deux faces de la pièce finale. Such a product makes it possible to obtain a composite material having an excellent surface finish on both sides of the final part.
La figure 4 illustre une quatrième variante dans laquelle deux voiles de polyester sont collés de part et d'autre du complexe (1,2,3) lié par couture. On obtient également un excellent état de surface ainsi que de très bonnes caractéristiques de déformation comparables à celles d'un matériau réalisé conformément aux enseignements du brevet FR-A-2 646 442.Figure 4 illustrates a fourth variant in which two sails of polyester are bonded on either side of the complex (1,2,3) linked by sewing. We also obtain an excellent surface condition as well as very good deformation characteristics comparable to those of a material produced in accordance with the teachings of patent FR-A-2 646,442.
Bien entendu, l'invention n'est pas limitée aux exemples de réalisation décrits précédemment, mais elle en couvre toutes les variantes réalisées dans le même esprit.Of course, the invention is not limited to the examples of realization described above, but it covers all variants carried out in the same spirit.
