Description
MATERIAU POUR LE RENFORCEMENT D'ARTICLES STRATIFIES.MATERIAL FOR REINFORCING LAMINATE ARTICLES.
La présente invention concerne un perfectionnement apporté aux matériaux -servant d'armature aux complexes stratifiés. The present invention relates to an improvement made to the materials serving as a reinforcement for laminate complexes.
Les matériaux stratifiés sont des articles bien connus. Schématiquement, les matériaux sont constitués par une pluralité de couches superposées de nappes textiles de renforcement, lesdites nappes étant imprégnées d'une résine appropriée qui, après traitement, notamment de polymérisation, permet de lier les différentes couches entre elles et d'obtenir un ensemble rigide et résistant. Laminate materials are well known items. Schematically, the materials are constituted by a plurality of superimposed layers of textile reinforcement plies, said plies being impregnated with a suitable resin which, after treatment, in particular of polymerization, makes it possible to bond the different layers together and to obtain a set rigid and resistant.
De tels articles stratifiés ont trouvé de nombreuses applications, notamment sous la forme de plaques ou panneaux, ainsi que pour la réalisation d'articles en forme tels que bateaux de plaisance, carrosseries.., voire même d'éléments creux tels que tubes, conduites, citernes ou réservoirs. Such laminated articles have found numerous applications, in particular in the form of plates or panels, as well as for the production of shaped articles such as pleasure boats, bodies, etc., or even hollow elements such as tubes, pipes. , tanks or reservoirs.
L'une des caractéristiques mécaniques recherchées dans les articles stratifiés est la rigidité qui est essentiellement fonction de l'épaisseur de l'armature de renforcement. Depuis fort lonatemps, afin d'une part de limiter le coût de l'armature et, d'autre part et surtout d'abaisser le poids, il a été proposé de réaliser des armatures comportant un noyau constitué d'une couche dé mousse (polyuréthane par exemple) de part et d'autre de laquelle sont disposés les renforts textiles proprement dits, renforts qui sont choisis en fonction des applications souhaitées. Par exemple, de tels renforts textiles peuvent être constitués par des nappes de fils parallèles, longitudinaux et/ou transversaux et/ou en biais par rapport à la longueur du noyau en mousse, éventuellement associés à des tissus, non tissés. One of the mechanical characteristics sought in laminated articles is rigidity which is essentially a function of the thickness of the reinforcing reinforcement. For a long time now, in order on the one hand to limit the cost of the armature and, on the other hand and above all to reduce the weight, it has been proposed to make armatures comprising a core consisting of a foam layer ( polyurethane for example) on either side of which are arranged the actual textile reinforcements, reinforcements which are chosen according to the desired applications. For example, such textile reinforcements can be constituted by plies of parallel, longitudinal and / or transverse yarns and / or at an angle with respect to the length of the foam core, possibly associated with fabrics, non-woven fabrics.
L'un des problèmes qui se posent pour la réalisation de telles armatures de type "sandwich" est celui de la liaison des différentes couches entre-elles, liaision qui, d'une part, doit permettre d'éviter qu'au cours des manipulations que subissent ces articles lors du stockage et du transport, les fils des différentes nappes se déplacement les uns par rapport aux autres et, d'autre part et surtout, n'entraîne pas une diminution ou altération des caractéristiques mécaniques du stratifié proprement dit. One of the problems which arise for the production of such “sandwich” type reinforcements is that of the connection of the different layers to each other, a bond which, on the one hand, must make it possible to avoid that during handling that these articles undergo during storage and transport, the threads of the different plies move relative to one another and, on the other hand and above all, do not cause a reduction or alteration of the mechanical characteristics of the laminate itself.
Or on a trouvé, et c'èst ce qui fait l'objet de la présente invention, qu'il était possible de résoudre ce problème en réalisant un tel complexe selon la technique bien connue dans le domaine de l'industrie textile sous l'appellation "couture/tricotage", technique qui de manière prévisible permet d'obtenir une très bonne liaison des couches entre elles mais qui, dans le cas de l'application conforme à la présente invention, avait été écartée par les techniciens, ce qui peut éventuellement s'expliquer par le fait que l'on aurait pû s'attendre à ce que la couche interne en mousse pouvait être détériorée par la pénétration des aiguilles de couture/tricotage alors que, de manière surprenante, lors d'une telle opération, non seulement dans le produit stratifié final les caractéristiques ne se trouvent pas amoindries mais. Now we have found, and this is what is the subject of the present invention, that it was possible to solve this problem by producing such a complex according to the technique well known in the field of the textile industry under the designation "sewing / knitting", a technique which predictably makes it possible to obtain a very good bond between the layers but which, in the case of the application in accordance with the present invention, had been rejected by the technicians, which can possibly explain by the fact that one could have expected that the internal foam layer could be deteriorated by the penetration of sewing / knitting needles whereas, surprisingly, during such an operation, not only in the final laminated product the characteristics are not reduced but.
au contraire, conduit à des stratifiés très homogènes, la résine étant non seulement parfaitement répartie de part et d'autre de la structure de renforcement mais pénétrant également au coeur du renfort en formant, à l'intérieur des orifices provoqués lors de la pénétration des aiguilles du métier des colonnes reliant les deux couches externes en résine.on the contrary, leads to very homogeneous laminates, the resin not only being perfectly distributed on either side of the reinforcement structure but also penetrating into the heart of the reinforcement by forming, inside the orifices caused during the penetration of the needles in the loom of the columns connecting the two outer resin layers.
Avantageusement et en pratique dans le matériau conforme à l'invention
- le noyau interne en mousse est constitué par une feuille de mousse à cellules fermées par exemple du type polyuréthane
- les renforts textiles disposés de part et d'autre de la couche interne en mousse sont associés à cette dernière lors de l'opération de couture/tricotage et peuvent être constitués
de fils parallèles, contigus ou espacés
les uns des autres,
de nappes bidirectionnelles, c'est-à-dire
constituées de deux séries de fils formant
entre eux un angle,de 90" par exemple, ces
fils pouvant être comme précédemment soit
contigus soit espacés les uns des autres,
les nappes uni ou bidirectionnelles peuvent
être éventuellement associées à des nappes
fibreuses, voire même à des tissus.Advantageously and in practice in the material according to the invention
the internal foam core consists of a sheet of closed cell foam, for example of the polyurethane type
- the textile reinforcements placed on either side of the internal foam layer are associated with the latter during the sewing / knitting operation and can be formed
parallel, contiguous or spaced wires
one another,
bidirectional sheets, that is to say
made up of two series of wires forming
between them an angle, of 90 "for example, these
son can be as before either
contiguous is spaced from each other,
uni or bidirectional tablecloths can
possibly be associated with tablecloths
fibrous, even tissue.
- par ailleurs, l'armure utilisée pour réaliser la couture/tricotage sera déterminée en fonction du complexe à réaliser. Ainsi, par exemple, dans l'hypothèse où on réalise un matériau comportant, de part et d'autre de la couche de mousse, une seule série de fils parallèles disposés transversalement par rapport à la longueur de l'article, la liaison peut être réalisée par un simple point de chainette. Dans l'hypothèse où les fils sont disposés longitudinalement, ou si les fils longitudinaux sont associés à des fils transversaux, pour obtenir le maintien de ces fils longitudinaux, il est évident qu'on devra utiliser une armure réalisant des jetées sur lesdits fils longitudinaux, par exemple une armure simple tricot
- de préférence, les fils de liage sont très fins par rapport aux autres renforts textiles.
L'invention et les avantages qu'elle apporte seront cependant mieux compris grâce à l'exemple de réalisation donné ci-après à titre indicatif mais non limitatif.- moreover, the weave used to make the sewing / knitting will be determined according to the complex to be made. Thus, for example, in the event that a material is produced comprising, on either side of the foam layer, a single series of parallel wires arranged transversely to the length of the article, the connection can be made with a simple chain stitch. In the hypothesis where the wires are arranged longitudinally, or if the longitudinal wires are associated with transverse wires, in order to obtain the maintenance of these longitudinal wires, it is obvious that we will have to use a weave making throws on said longitudinal wires, for example a simple knit weave
- Preferably, the binding son are very fine compared to other textile reinforcements.
The invention and the advantages which it brings will however be better understood thanks to the embodiment given below for information but not limitation.
Exemple
Sur un métier conventionnel de couture/tricotage, jauge 7, on réalise une armature conforme à ltinvention comportant
- une couche interne (noyau) constituée par une feuille de mousse de polyuréthane à cellule fermée, ayant une épaisseur de deux millimètres
- deux renforts textiles disposés de part et d'autre de la couche de mousse précitée et constitués de deux tissus bidirectionnels comportant
en chaîne : des fils de verre (roving) de
1 200 tex ; la densité de la chaîne : 5 fils/-n ;
en trame : des fils de verre (roving) de
600 tex ; la densité de
trame : 5 fils/c ;
Ces trois couches sont liées entre elles sur le métier même au moyen de fils polyester de 190 Otex. Example
On a conventional sewing / knitting loom, gauge 7, a frame is produced in accordance with the invention comprising
- an internal layer (core) consisting of a sheet of polyurethane foam with closed cell, having a thickness of two millimeters
- two textile reinforcements arranged on either side of the aforementioned foam layer and made up of two bidirectional fabrics comprising
in chain: roving glass
1,200 tex; the chain density: 5 threads / -n;
in weft: glass roving
600 tex; the density of
weft: 5 threads / c;
These three layers are linked together on the loom itself by means of 190 Otex polyester threads.
A la tombée du métier, l'article se présente sous la forme d'un complexe parfaitement homogène dans lequel les nappes textiles tissées sont parfaitement liées à la couche de mousse interne. At the end of the trade, the article is in the form of a perfectly homogeneous complex in which the woven textile sheets are perfectly linked to the internal foam layer.
Un tel matériau peut être utilisé pour la réalisation de tout stratifié, par exemple pour réaliser des plaques présentant de très bonnes caractéristiques de résistance à la flexion. Such a material can be used for the production of any laminate, for example for producing plates having very good flexural strength characteristics.
