Definitions
- the invention relates to an improvement made to the textile reinforcements used for the production of a composite material, that is to say articles based on resin (polyester or others), reinforced with a textile reinforcement ply.
- the reinforcement which is the subject of the aforementioned patent consists of at least two layers of textile reinforcement proper, disposed on either side of a central layer giving the thickness of said material and it characterized in that the said central layer consists of a sheet based on synthetic fibers, of high unitary strength and which have received, prior to their forming in the form of a sheet, a treatment communicating to them a permanent ripple or crimp leading to the formation of a light, thick and airy tablecloth.
- the different layers are linked together by sewing / knitting.
- the textile reinforcement layers placed on either side of the central layer giving the thickness are advantageously made up of fibrous mats possibly associated with other textile reinforcements.
- 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.
- connection of the different layers by sewing / knitting sometimes leads to surface appearance defects, in particular on the chain side that such connections form.
- the improvement according to the invention consists, in a frame of the type which is the subject of the aforementioned French patent and which therefore comprises at least two layers of textile reinforcement arranged on either side of a layer central unit giving the thickness to said material, said layers being linked together by sewing / knitting, to be added, at least against one of the external faces of the complex, a veil of synthetic fibers, the bonding of said veil being carried out either by bonding to outside the complex, either through the seams linking the different layers together.
- the central ply is preferably based on synthetic fibers of high titer and crimped in a manner similar to the aforementioned patent, but can also be based on other coarse fibers, for example vegetable fibers.
- This central ply preferably has a weight of between 150 g / m2 and 400 g / m2. Indeed, for a weight less than 150 g / m2, the complex lacks strength and regularity, while a weight greater than 400 g / m2 leads to thick products which are not justified in practice.
- the thickness of this central ply is generally between 3 and about 8 mm.
- the textile reinforcement layers arranged on either side of the central layer are advantageously constituted by a glass mat, possibly reinforced by a textile grid, the weight of these layers generally being between 300 and 600 g / m2.
- a veil of synthetic fibers having a grammage of between 50 and 150 g / m2 will be used, the synthetic fibers used in the production of such a veil being very fine, and generally having a count of between 1 and 7 dtex , that is to say much finer fibers than those used in the composition of the reinforcement itself.
- Such fineness of the surface fibers makes it possible to have very good homogeneity, promoting the distribution of the resin during molding. Furthermore, these surface fibers prevent marking by the coarse fibers of the internal structure.
- this basic structure is associated, at least against one of the external faces, with a veil of synthetic fibers designated by the reference (4).
- This or these veils (4) can either be glued to the outside of the three-layer complex linked by sewing / knitting, or be attached against one or other of the external faces of the complex before they are linked by sewing / knitting.
- FIG. 2 illustrates an embodiment in which the same polyester veil (4) is attached to the outside of the complex (1,2,3) previously bonded by sewing / knitting.
- two webs (4) are associated on either side of the complex, one disposed against the web (3) being sewn, the other disposed against the web (2) being glued above the seams.
- Such a product makes it possible to obtain a composite material having an excellent surface condition on both sides of the final part.
- FIG. 4 illustrates a fourth variant in which two polyester veils are glued on either side of the complex (1,2,3) linked by sewing. An excellent surface condition is also obtained, 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.
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 the textile reinforcements used for the production of a composite material, that is to say articles based on resin (polyester or others), reinforced with a textile reinforcement ply.
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 made to the reinforcements which are the subject of FR-A-2 646 442 in the name of the Applicant, the content of which is integrated into the present application 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 reinforcement which is the subject of the aforementioned patent consists of at least two layers of textile reinforcement proper, disposed on either side of a central layer giving the thickness of said material and it characterized in that the said central layer consists of a sheet based on synthetic fibers, of high unitary strength and which have received, prior to their forming in the form of a sheet, a treatment communicating to them a permanent ripple or crimp leading to the formation of a light, thick and airy tablecloth. 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.Furthermore, the textile reinforcement layers placed on either side of the central layer giving the thickness, are advantageously made up of fibrous mats possibly associated with other textile reinforcements.
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 entraînait 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 of the different layers by sewing / knitting sometimes leads to surface appearance defects, in particular on the chain side that such connections form.
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.However, it was found, and this is the subject of the present invention, that it was possible not only to improve the surface condition of the composite material comprising such a reinforcement, but also to adapt certain technical characteristics such as dimensional stability 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.In general, the improvement according to the invention consists, in a frame of the type which is the subject of the aforementioned French patent and which therefore comprises at least two layers of textile reinforcement arranged on either side of a layer central unit giving the thickness to said material, said layers being linked together by sewing / knitting, to be added, at least against one of the external faces of the complex, a veil of synthetic fibers, the bonding of said veil being carried out either by bonding to outside the complex, either through the seams linking 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 titer and crimped in a manner similar to the aforementioned patent, but can also be based on other coarse fibers, for example vegetable fibers. This central ply preferably has a weight of between 150 g / m2 and 400 g / m2. Indeed, for a weight less than 150 g / m2, the complex lacks strength and regularity, while a weight greater than 400 g / m2 leads to thick products which are not justified in practice. The thickness of this central ply is generally 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 arranged on either side of the central layer are advantageously constituted by a glass mat, possibly reinforced by a textile grid, the weight of these layers generally being 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 of between 50 and 150 g / m2 will be used, the synthetic fibers used in the production of such a veil being very fine, and generally having a count of between 1 and 7 dtex , that is to say much finer fibers than those used in the composition of the reinforcement itself. Such fineness of the surface fibers makes it possible to have very good homogeneity, promoting the distribution of the resin during molding. Furthermore, these surface fibers prevent marking by the coarse fibers of the 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 embodiments given below by way of indication but not limitation, these examples being illustrated by Figures 1 to 4 appended corresponding to four types of product produced in accordance with 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.In accordance with the invention, this basic structure is associated, at least against one of the external faces, with a veil of synthetic fibers designated by the reference (4). This or these veils (4) can either be glued to the outside of the three-layer complex linked by sewing / knitting, or be attached against one or other of the external faces of the complex before they are 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 embodiment illustrated in FIG. 1, a single veil (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 by means of a polyester thread having a title 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 the complexes produced in accordance with the teachings of FR-A-2 646 442 not comprising polyester fleece, a better surface condition is obtained during the production of the composite material. Furthermore, such a structure has better dimensional stability and deforms less.
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.FIG. 2 illustrates an embodiment in which the same polyester veil (4) is attached to the outside of the complex (1,2,3) previously bonded 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 FIG. 1, a better surface condition is obtained as well as a 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 webs (4) are associated on either side of the complex, one disposed against the web (3) being sewn, the other disposed against the web (2) being glued above the 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 condition 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.FIG. 4 illustrates a fourth variant in which two polyester veils are glued on either side of the complex (1,2,3) linked by sewing. An excellent surface condition is also obtained, 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 embodiments described above, but it covers all the variants produced in the same spirit.
