Abstract

The technical fabric, designed to be coated with resin, is made in two layers (N,M) based on glass or carbon fibers, woven simultaneously on a loom with double weft insertion, as for silk velvet, with layers linked by warp ties in X-formation. The technical fabric, designed to be coated with resin, is made in two layers (N,M) based on glass or carbon fibers, woven simultaneously on a loom with double weft insertion, as for silk velvet, with layers linked by warp ties in X-formation. The angle of inclination of ties is about 45[deg], adjustable according to length of float loop by increasing or reducing number of weft yarns per section (A) between ties.

Description

La présente invention se rapporte au tissage, chaîne et trame, de tissusThe present invention relates to weaving, warp and weft, of fabrics

techniques doubles nappes, destinés à être enduit de résine époxy ou autre, afin de réaliser des panneaux ou poutres, dont la résistance à la flexion est accrue.  double ply techniques, intended to be coated with epoxy resin or other, in order to produce panels or beams, whose flexural strength is increased.

Exemple d'utilisation, mat de voilier, panneaux entrant dans la construction de remorque de camion. 5 La technique de tissage de ce tissu est similaire à celle du velours soierie tissé sur une machine à double insertion de trame (machine velours à deux navettes ou métiers à doubles lances) La différence entre les armures velours existantes et celles de ce tissu technique, tient à la Liaison des deux nappes textile (le poil sur les métiers 10 velours) Cette liaison s'organise comme le montre la coupe sens chaîne de la figure 1. Dans cette coupe (N) et (M) sont les nappes, (P) le peigne du métier à tisser. Comme dans les armures velours, la partie (B) est la liaison du fil à la nappe tissée, elle peut prendre toutes sortes de formes en fonction de l'armure de la 15 nappe, comme sur les armures velours classiques.  Example of use, sailboat mast, panels entering the truck trailer construction. The weaving technique of this fabric is similar to that of the silkweave velvet woven on a double weft insertion machine (velvet machine with two shuttles or looms with double lances). The difference between the existing velvet armor and that of this technical fabric, It is linked to the two textile plies (the pile on the pile looms). This connection is organized as shown by the chain-cut section of FIG. 1. In this section (N) and (M) are the plies, (P). ) the comb of the loom. As in velvet armor, the part (B) is the bond of the yarn to the woven web, it can take all kinds of shapes depending on the weave of the web, as on conventional velvet armor.

La partie (A) est un long flotté entre les deux nappes, la longueur de ce flotté est définie par: - la réduction du tissu l'angle (Y) que l'on veut donner au fil de liaison 20 - la cote (H) d'écartement des deux nappes Les fils de liage présentent entre deux encrages consécutifs sur les nappes haute et basse un long flotté qui dans le tissu technique terminé se traduit par une inclinaison importante des liaisons entre les deux nappes.  The part (A) is a long float between the two layers, the length of this float is defined by: - the reduction of the fabric angle (Y) that we want to give to the wire 20 - the dimension (H The binder yarns have between two consecutive inking on the high and low plies a long float which in the finished technical fabric results in a significant inclination of the connections between the two plies.

Cet angle (Y) d'environ 45 est réglable à la conception du tissu. 25 En fonction des contraintes subies par la poutre, l'angle (Y) peut être ajusté au mieux en augmentant ou en diminuant le nombre de duites de la partie (A).  This angle (Y) of approximately 45 is adjustable at the design of the fabric. Depending on the stresses experienced by the beam, the angle (Y) may be best adjusted by increasing or decreasing the number of picks of the portion (A).

La répartition de ces fils de liaison dans la largeur du tissu peut être réalisée suivant des armures, taffetas, cannelé, sergé, satin ou autres armures irrégulières. 30 Ainsi tissé et enduit de résine les panneaux ou poutres présentent une résistance accrue à la flexion, dans le sens chaîne, car les fils de liage rigidifiés par la résine forment un X, qui est la forme la plus adapté pour résister aux efforts de flexion de la poutre ou du panneau.  The distribution of these bonding yarns in the width of the fabric can be carried out according to weaves, taffeta, fluted, twill, satin or other irregular weaves. Thus woven and resin-coated panels or beams have an increased resistance to bending, in the warp direction, because the binding threads stiffened by the resin form an X, which is the most suitable shape to withstand the bending forces beam or panel.

C'est la différence importante entre les essais déjà réalisés à partir de velours 35 tricotés sur métier Rachel à double fronture, ou les fils de liage étaient perpendiculaire aux nappes assemblées et donc parallèle entre eux.  This is the important difference between the tests already made from velvet knitted on a Rachel double-sided loom, or the binding yarns were perpendicular to the assembled plies and therefore parallel to each other.

D'autre part, il est possible de tisser de très gros fils de verre ou de carbone ce qui est impossible en tricotage.  On the other hand, it is possible to weave very large glass or carbon threads which is impossible in knitting.

Pour le tissage de ce tissu sur un métier velours: É le système de coupe doit être supprimé É les rouleaux d'appel du régulateur doivent être remplacés. par un seul rouleau à picots.  For the weaving of this fabric on a pile machine: É the cutting system must be removed É the call rollers of the regulator must be replaced. by a single spiked roller.

É Le ou les compensateurs de fils de liaison doivent avoir une plus grande 5 amplitude de façon à maintenir tendu les fils de liage pendant le tissage de la partie (A).  The binding yarn compensator (s) must have a greater amplitude so as to keep the binding yarns taut during the weaving of the part (A).
