Description
ARMATURE TEXTILE UTILISABLE POUR LA REALISATION DE MATERIAUX COMPOSITES.TEXTILE REINFORCEMENT FOR USE IN THE PRODUCTION OF COMPOSITE MATERIALS.
L'invention concerne un perfectionnement apporté aux armatures textiles utilisées pour la réalisation de matériaux composites, c'est-à-dire d'articles à base d'une résine renforcée par une structure textile.The invention relates to an improvement made to the textile reinforcements used for the production of composite materials, that is to say articles based on a resin reinforced by a textile structure.
A ce jour, en fonction des applications et des caractéristiques recherchées, de très nombreuses structures textiles de renforcement sont utilisées dans le domaine des composites, tels que par exemple tissus, grilles textiles, non tissés ou combinaisons de tels éléments.To date, depending on the applications and the desired characteristics, numerous textile reinforcing structures are used in the field of composites, such as for example fabrics, textile grids, nonwovens or combinations of such elements.
Dans le brevet français 2 646 442, le Demandeur a proposé une armature textile particulièrement adaptée pour réaliser des renforts de forte épaisseur, caractéristique nécessaire lorsque l'on souhaite réaliser des éléments tels que carrosserie de véhicules, coques de bateaux de plaisance, citernes ..., qui doivent présenter une grande rigidité.In French patent 2,646,442, the Applicant proposed a textile reinforcement which is particularly suitable for producing thick reinforcements, a characteristic necessary when it is desired to produce elements such as vehicle bodywork, pleasure boat hulls, tanks, etc. ., which must be very rigid.
Une telle armature 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 audit matériau, ladite couche centrale étant constituée par une nappe à base de fibres synthétiques, de titre unitaire élevé, ayant reçu préalablement à leur mise sous forme de nappe un traitement leur communiquant une ondulation (ou frisure) permanente.Such a frame is constituted by at least two layers of textile reinforcement proper, disposed on either side of a central layer giving the thickness to said material, said central layer being constituted by a ply based on synthetic fibers, high unit strength, having received prior to their tablecloth treatment treating them with a permanent undulation (or crimp).
En d'autres termes, dans l'armature faisant l'objet du brevet précité, la constitution de la nappe fibreuse interne du complexe est à base de fibres présentant un effet "de ressort" qui autorise la production d'une nappe non tissée légère, épaisse et aérée.
Un tel complexe est particulièrement adapté pour réaliser des structures de forme complexe obtenues par moulage par injection selon les techniques dites "par moulage à la presse avec injection" ou "moulage sous vide" par le fait qu'elle permet d'obtenir une répartition très homogène de la résine sur toute l'épaisseur et toutes les directions.In other words, in the reinforcement which is the subject of the aforementioned patent, the constitution of the internal fibrous web of the complex is based on fibers having a "spring" effect which allows the production of a light nonwoven web. , thick and airy. Such a complex is particularly suitable for producing structures of complex shape obtained by injection molding according to techniques known as "by press molding with injection" or "vacuum molding" by the fact that it makes it possible to obtain a very homogeneous resin throughout the thickness and in all directions.
Or on a trouvé, et c'est ce qui fait l'objet de la présente invention, qu'il était possible d'améliorer encore les caractéristiques que permettent d'obtenir de telles armatures constituées par au moins deux couches de renfort textile disposées de part et d'autre d'une couche centrale donnant l'épaisseur audit matériau en réalisant la couche centrale non pas à partir de fibres synthétiques, de titre unitaire élevé, ayant reçu un traitement leur communiquant une ondulation permanente, mais, au lieu et place de telles fibres, des fibres naturelles et plus particulièrement des fibres végétales aptes à être conformées sous la forme d'une nappe non tissée légère, épaisse, aérée en présentant une bonne tenue en compression.However, it has been found, and this is the subject of the present invention, that it was possible to further improve the characteristics which such reinforcements make it possible to obtain, consisting of at least two layers of textile reinforcement disposed of on either side of a central layer giving the thickness to said material by producing the central layer not from synthetic fibers, of high unit strength, having received a treatment imparting to them a permanent undulation, but, instead such fibers, natural fibers and more particularly vegetable fibers capable of being shaped in the form of a light, thick, airy nonwoven web having good compressive strength.
Comme type de fibres végétales pouvant permettre la réalisation d'une telle structure fibreuse interne, on utilisera de préférence des fibres extraites de feuilles telles que par exemple des fibres de sisal ou similaires, ainsi que des fibres extraites de gousses ou fruits, notamment kapok, coco, qui sont des fibres relativement grossières dont les caractéristiques permettent d'obtenir des nappes présentant une très bonne tenue en compression.
L'utilisation de telles fibres grossières, permet d'obtenir, à poids égal, par rapport à des nappes à base de fibres synthétiques frisées, des nappes plus aérées et résistant mieux à la compression, facilitant les opérations de moulage, la répartition de la résine se faisant de manière très homogène sur toute l'épaisseur et toutes les directions du matériau.As a type of vegetable fiber which can allow the production of such an internal fibrous structure, use will preferably be made of fibers extracted from leaves such as for example sisal fibers or the like, as well as fibers extracted from pods or fruits, in particular kapok, coconuts, which are relatively coarse fibers whose characteristics make it possible to obtain plies having a very good resistance to compression. The use of such coarse fibers makes it possible to obtain, with equal weight, compared to plies based on crimped synthetic fibers, more aerated plies and better resistant to compression, facilitating the molding operations, the distribution of the resin being made very homogeneously over the entire thickness and all the directions of the material.
Une telle nappe interne réalisée à partir de fibres naturelles est obtenue par cardage et nappage ou tout autre moyen équivalent.Such an internal layer produced from natural fibers is obtained by carding and coating or any other equivalent means.
De manière connue, conformément aux enseignements du FR-A- 2 646 442, de part et d'autre de cette nappe interne, sont disposés des renforts textiles pouvant être constitués :In known manner, in accordance with the teachings of FR-A-2 646 442, on either side of this internal ply, textile reinforcements can be arranged:
- de fils parallèles jointifs contigus ou espacés les uns des autres,- contiguous parallel wires contiguous or spaced from each other,
- de nappes bidirectionnelles, c'est-à-dire constituées de séries de fils pouvant former entre eux un angle de 90° ;- bidirectional sheets, that is to say made up of series of wires which can form an angle of 90 ° between them;
- de nappes fibreuses telles que par exemple nappes de fibres de verre réparties au hasard de part et d'autre de l'âme précitée, ces nappes fibreuses pouvant être associées à des nappes uni ou bidirectionnelles, voire même à des tissus.- Fibrous sheets such as for example sheets of glass fibers distributed randomly on either side of the aforementioned core, these fibrous sheets can be associated with plain or bidirectional sheets, or even with fabrics.
La liaison des différentes nappes entre elles est réalisée soit par couture/tricotage, soit par liage par aiguilletage mécanique.The connection of the various plies together is carried out either by sewing / knitting, or by binding by mechanical needling.
L'invention et les avantages qu'elle apporte sera cependant mieux comprise grâce à l'exemple de réalisation donné ci-après à titre indicatif mais non limitatif.
ExempleThe invention and the advantages which it brings will however be better understood thanks to the example of embodiment given below by way of indication but not limitation. Example
Sur une machine conventionnelle permettant le complexage de structures textiles planes (machines de couture/ tricotage ou machines d'entrelaçage par aiguilletage), on réalise une armature conforme à l'invention comportant :On a conventional machine allowing the complexing of flat textile structures (sewing / knitting machines or interlacing machines by needling), a frame is produced according to the invention comprising:
- une couche interne constituée par une nappe non tissée, réalisée par cardage et nappage à partir de fibres de sisal, ayant une longueur comprise entre 40 mm et 100 mm ; cette nappe obtenue par cardage/nappage pèse entre 350 et 500 g/m2 et a une épaisseur d'environ 4 mm ;- an internal layer constituted by a nonwoven sheet, produced by carding and topping from sisal fibers, having a length of between 40 mm and 100 mm; this sheet obtained by carding / coating weighs between 350 and 500 g / m2 and has a thickness of approximately 4 mm;
- deux nappes de renfort textile proprement dites sont disposées de part et d'autre de la couche interne précitée, ces nappes de renfort textile étant constituées toutes les deux par un mat de verre pesant 450 g/m2, obtenu par des coupes de fibres de verre et nappage conventionnel par voie sèche ; ces fibres de verre ont un titre de 40 tex, la longueur de coupe étant de 50 mm ; lorsque les couches sont liées par couture, elles le sont au moyen de fils de polyester ayant un titre de 167 dtex ; lors de liaison par aiguilletage mécanique, le traitement est effectué sur les deux faces de l'empilement de textile.- two textile reinforcement plies proper are arranged on either side of the abovementioned internal layer, these textile reinforcement plies being both constituted by a glass mat weighing 450 g / m2, obtained by cutting fibers of glass and conventional dry topping; these glass fibers have a titer of 40 tex, the cutting length being 50 mm; when the layers are linked by sewing, they are linked by means of polyester threads having a count of 167 dtex; during bonding by mechanical needling, the treatment is carried out on both sides of the textile stack.
Après liaison des différentes couches entre elles, la structure a une épaisseur d'environ 4,5 mm.
Un tel matériau peut être utilisé comme structure de renfort d'articles moulés à base de résine thermodurcissable. En général, ce matériau représente 15 à 25 % du poids total de l'article moulé.After bonding the different layers together, the structure has a thickness of around 4.5 mm. Such a material can be used as a reinforcement structure for molded articles based on thermosetting resin. In general, this material represents 15 to 25% of the total weight of the molded article.
Bien entendu, l'invention n'est pas limitée à l'exemple de réalisation donné précédemment, mais elle en couvre toutes les variantes réalisées dans le même esprit.
Of course, the invention is not limited to the embodiment given above, but it covers all the variants produced in the same spirit.
