Abstract
Description
L'invention est relative aux éléments de structure, tels que barre, bielle, entretoise, poutre, élément de charpente, et arbre de torsion, réalisés en matériaux composites et destinés à supporter les contraintes mécaniques élevées d'extension, de compression, de flexion ou de cisaillement. The invention relates to structural elements, such as bar, connecting rod, spacer, beam, structural element, and torsion shaft, made of composite materials and intended to withstand the high mechanical stresses of extension, compression, bending. or shear.
De tels éléments sont en général composés d'un tube en matériaux composites dont les extrémités sont rendues solidaires de pièces métalliques de fixation. Such elements are generally composed of a tube made of composite materials, the ends of which are made integral with metal fixing parts.
L'un des procédés de fabrication actuels consiste à fabriquer l'âme tubulaire sur des mandrins, en plusieurs parties ou nonolithique, démontables ou non, puis à coller à l'extrémité de l'âme obtenue, les pièces métalliques de liaison. Dans ce cas, il est nécessaire d'avoir recours b des mandrins de positionnement dérnontables. One of the current manufacturing methods consists in manufacturing the tubular core on mandrels, in several parts or nonolithic, removable or not, and then gluing the metal connecting pieces to the end of the core obtained. In this case, it is necessary to use non-detachable positioning mandrels.
Un autre procédé consiste à fabriquer l'âme tubulaire sur des mandrins en cire, soluble après polymérisation de l'âme, ou sur des mandrins en mousse synthétique. Cette technique nécessite de prévoir, après la polymérisation de l'âme, une phase de fabrication complémentaire consistant à diluer le mandrin pour le faire disparaitre, ou à l'extraire du tube obtenu. Another method consists in manufacturing the tubular core on wax mandrels, soluble after polymerization of the core, or on mandrels made of synthetic foam. This technique requires providing, after the polymerization of the core, a complementary manufacturing phase consisting in diluting the mandrel to make it disappear, or in extracting it from the tube obtained.
De plus, elle exige que l'une des extrémités de l'élément, soit ouverte pour permettre l'élimination du mandrin. In addition, it requires that one end of the element is open to allow the removal of the mandrel.
Il ressort de ce qui précède que les éléments de structure en matériaux composites actuels sont délicats à réaliser, sont onéreux et conduisent à de nombreuses reprises de fabrication qui interfèrent sur leurs caractéristiques mécaniques et ne permettent pas toujours d'obtenir les valeurs de résistance recherchée. It emerges from the above that the structural elements made of current composite materials are difficult to produce, are expensive and lead to numerous manufacturing runs which interfere with their mechanical characteristics and do not always make it possible to obtain the desired resistance values.
La présente invention a pour but de fournir un élément de structure, plus facile à réaliser, pouvant résister à des contraintes élevées, tout en ayant une plus grande légèreté que des pièces métalliques de performances identiques et dont la résistance peut tre adaptée au type de contrainte que doit supporter cet élément. The present invention aims to provide a structural element, easier to produce, able to withstand high stresses, while having greater lightness than metal parts of identical performance and whose resistance can be adapted to the type of stress. that this element has to bear.
A cet effet, dans cet élément de structure, du type comprenant un tube composé d'un enroulement filamentaire et des pièces extrêmes de fixation, les pièces de fixation sont liées mécaniquement à une âme en matière thermo-plastique, de caractéristique mécanique adaptée b l'application, âme sur laquelle est enroulé l'enroulement filamentaire de renfort. To this end, in this structural element, of the type comprising a tube composed of a filament winding and extreme fixing parts, the fixing parts are mechanically linked to a core of thermo-plastic material, of mechanical characteristic suitable for b l 'application, core on which the reinforcing filament winding is wound.
Ainsi, l'élément est composé d'un enroulement filamentaire de renfort et d'un sous-ensemble qui, comprenant les pièces de fixation extrême et leur âme de liaison, assurent la liaison permanente de ses pièces et constituent mandrin pour l'enroulement. Grâce b celas les pièces sont liées l'une a l'autre å la fois par l'âme et par l'enroulement. Thus, the element is composed of a reinforcing filament winding and a sub-assembly which, comprising the extreme fixing parts and their connecting core, ensure the permanent connection of its parts and constitute a mandrel for the winding. Thanks to this, the parts are linked to each other both by the core and by the winding.
L'invention vise également le procédé de fabrication de cet élément de structure. The invention also relates to the method of manufacturing this structural element.
Ce procédé consiste, d'abord, å assurer la liaison des pièces extrêmes de liaison avec une âme en matière thermo-plastique, puis, å utiliser l'ensemble obtenu comme mandrin pour l'enroulage des fibres composant l'enroulement filamentaire du tube de renfort externe en matériaux composites. This process consists, first, in ensuring the connection of the extreme connection pieces with a core of thermoplastic material, then, in using the assembly obtained as a mandrel for winding the fibers composing the filament winding of the tube. external reinforcement in composite materials.

Dans ces dessins, 2 désigne un ensemble composite forme de fibres, telles que fibres d'aramide, de verre, de carbone, de bore ou autres, liées å une matrice, telle que résine époxyde, polyester, vinylester ou thermoplastique. De façon connue, cette partie assure la résistance mécanique de l'élément lorsque celui-ci est soumis à des efforts de traction, de compression, de torsion ou de flexion. In these drawings, 2 denotes a composite assembly formed of fibers, such as aramid, glass, carbon, boron or other fibers, bonded to a matrix, such as epoxy resin, polyester, vinylester or thermoplastic. In known manner, this part ensures the mechanical resistance of the element when the latter is subjected to tensile, compression, torsion or bending forces.
1 désigne l'une des deux pièces métalliques fixée aux extrémités de cet enroulement et réalisée en acier, en alliage d'aluminium, en titane ou autre. 1 designates one of the two metal parts fixed to the ends of this winding and made of steel, aluminum alloy, titanium or the like.
Selon l'invention, les deux pièces extrêmes 1 de chacun des éléments de structure, selon l'invention, sont liées l'une å l'autre par une me en matière thermoplastique 3. According to the invention, the two end pieces 1 of each of the structural elements according to the invention are connected to each other by a core made of thermoplastic material 3.
Comme le montre les figures, chaque pièce extrême 1 est en forme de coupelle, c'est à dire comporte une jupe évasée 5 comportant au moins sur sa face externe un profil en escalier 6. La coupelle est solidaire de moyens de fixation pouvant être constituer par une tige filetée 7 avec écrou 8, fixe ou tournant, par une tête de bielle 9, comme représenté B la figure 5, par une chape de fixation 10 comme montré à la figure 6, par un système å bille à enclenchement rapide ou par tout autre moyen. As shown in the figures, each end piece 1 is in the form of a cup, that is to say has a flared skirt 5 comprising at least on its external face a staircase profile 6. The cup is secured to fixing means which can be constituted by a threaded rod 7 with nut 8, fixed or rotating, by a connecting rod head 9, as shown in FIG. 5, by a fixing yoke 10 as shown in FIG. 6, by a quick-engagement ball system or by any other way.
Dans la forme d'exécution représentée à la figure 1, l'âme 3 est tubulaire et délimite une cavité interne 3a qui peut être utilisée å l'état vide, ou comme montré à la figure 2, remplie par une mousse 4 en matière synthétique renforçant sa rigidité et sa tenue. In the embodiment shown in Figure 1, the core 3 is tubular and defines an internal cavity 3a which can be used in an empty state, or as shown in Figure 2, filled with a foam 4 of synthetic material strengthening its rigidity and its hold.
Dans la forme d'exécution représentée à la figure 3, l'même référencée 3b est monolithique et forme une barre de section pleine.In the embodiment shown in Figure 3, the same referenced 3b is monolithic and forms a solid section bar.
L'âme 3 ou 3b peut présenter toute section circulaire, elliptique ou polygonale, en fonction des besoins et des applications.Un tel élément de structure est fabriqué de la façon suivante. The core 3 or 3b can have any circular, elliptical or polygonal section, depending on needs and applications. Such a structural element is manufactured in the following manner.
Les deux pièces extrêmes de fixation sont préalablement enduites sur leurs faces devant venir en contact avec l' me 3 par une couche de matière thermoplastique de même nature que celle devant constituer l'âme 3. Elles sont ensuite disposées dans un moule de rotomoulage qui, après fermeture, reçoit une quantité dosée de matière thermoplastique a l'état fondu ou à l'état pulvérulent. Après polymérisation et durcissement de la matière thermoplastique et ouverture du moule, les deux pièces de fixation sont liées l'une à l'autre par l'ame 3 et forment ainsi un ensemble ayant la forme générale des mandrins utilisés pour assurer l'enroulement filamentaire des fibres constituant l'ensemble composite 2.Il est alors procédé à l'enroulement filamentaire de ces fibres sur le mandrin ainsi obtenu. The two extreme fixing parts are previously coated on their faces which must come into contact with the core 3 with a layer of thermoplastic material of the same nature as that which constitutes the core 3. They are then placed in a rotational molding mold which, after closing, receives a metered quantity of thermoplastic material in the molten state or in the pulverulent state. After polymerization and hardening of the thermoplastic material and opening of the mold, the two fixing parts are linked to each other by the core 3 and thus form an assembly having the general shape of the mandrels used to ensure the filament winding. fibers constituting the composite assembly 2. It is then proceeded to the filament winding of these fibers on the mandrel thus obtained.
Bien entendu, ces fibres peuvent être imprégnées ou non de le matière syntétique constituant leur matrice de liaison.Of course, these fibers may or may not be impregnated with the synthetic material constituting their binding matrix.
Il faut noter que grâce b leur forme extérieure en profil d'escalier 6, les coupelles 5 des pièces extrêmes assurent un bon accrochage de l'enroulement filamentaire, ce qui permet la reprise totale des efforts mécaniques en traction entre l'ensemble composite 2 et ses pièces d'extrémité 1. It should be noted that owing to their external shape in the form of a staircase profile 6, the cups 5 of the end pieces ensure good attachment of the filament winding, which allows total recovery of the mechanical tensile forces between the composite assembly 2 and its end pieces 1.
Pour certaines applications nécessitant un enroulement filamentaire sous forte tension, pouvant déformer le mandrin ainsi obtenu, celui-ci est renforcé par la matière synthétique expansé 4, comme montré a la figure 2, ou présente une section pleine comme représenté en 3b à la figure 3. L'injection de mousse 4 est aussi utilisée pour des éléments de structure ayant des sections importantes afin de renforcer la rigidité de ces éléments. For certain applications requiring a high tension filament winding, which can deform the mandrel thus obtained, it is reinforced by the expanded synthetic material 4, as shown in FIG. 2, or has a solid section as shown in 3b in FIG. 3 The injection of foam 4 is also used for structural elements having large sections in order to reinforce the rigidity of these elements.
Enfin, l'ensemble formé par les pièces d'extrémité 1 et l'âme 3 peut être renforcé par un enroulement filamentaire externe imprégné de résine mais sans apport de résine complémentaire. Finally, the assembly formed by the end pieces 1 and the core 3 can be reinforced by an external filament winding impregnated with resin but without the addition of additional resin.
Dans la variante d'exécution représentée h la figure 4, l'âme 3 est elle-même renforcée à coeur par au moins une nappe de renfort 12 conformée tubulairement. Cette nappe, préimprégnée ou non, par la matière synthétique constituant l' me 31 est disposée dans le moule de rotomoulage avant introduction de la matière synthétique et avant chauffage et fusion de celle-ci. De préférence, dans cette application visant la fabrication de barre, la matière thermoplastique constitutive de l'âme 3 est choisie parmi celle présentant une haute résistance et un faible allongement. In the alternative embodiment shown in FIG. 4, the core 3 is itself reinforced to the core by at least one reinforcing ply 12 tubularly shaped. This sheet, pre-impregnated or not, with the synthetic material constituting the me 31 is disposed in the rotational molding mold before introduction of the synthetic material and before heating and melting of the latter. Preferably, in this application for the production of bars, the thermoplastic material constituting the core 3 is chosen from that having a high resistance and a low elongation.
Dans une variante de réalisation, visent la fabrication de barres et d'entretoises, l'élément de structure est réalisé b partir d'un tube en matériau thermoplastique, renforcé ou non par la nappe 12, et dont les extrémités sont fondues, dans un moule de positionnement approprié, sur les pièces d'extrémité 1 préalablement traitées en surface. Après cette opération, l'ensemble obtenu est composé du tube solidaire des deux pièces extrêmes et constitue, comme dans la forme d'exécution précédente, mandrin permettant l'enroulement filamentaire de la couche externe de renfort. In an alternative embodiment, aim at the manufacture of bars and spacers, the structural element is made from a tube of thermoplastic material, reinforced or not by the web 12, and the ends of which are melted, in a suitable positioning mold, on the end pieces 1 previously treated on the surface. After this operation, the assembly obtained is composed of the tube integral with the two extreme parts and constitutes, as in the previous embodiment, a mandrel allowing the filament winding of the external reinforcement layer.
Il ressort de ce qui précède que quelque que soit sa forme de mise en oeuvre, ce procédé de fabrication permet d'obtenir en une seule opération la liaison des deux pièces extrêmes et la constitution d'un mandrin d'enroulage filamentaire permettant de faciliter la réalisation de l'élément de structure, mais aussi d'adapter les caractéristiques mécaniques de cet élément å son application. It follows from the above that whatever its form of implementation, this manufacturing process makes it possible to obtain in a single operation the connection of the two extreme parts and the constitution of a filament winding mandrel making it possible to facilitate the realization of the structural element, but also to adapt the mechanical characteristics of this element to its application.
Un tel élément de structure peut être utilisé pour fabriquer des arbres, des manivelles, des bielles de traction, des barres de torsion, des éléments de construction pour antenne, pilône, hangar, pour couverture démontable, des éléments de structure pour bâtiments et charpente, et tous éléments pour l'industrie. Such a structural element can be used to manufacture trees, cranks, connecting rods, torsion bars, construction elements for antenna, pylon, shed, for removable cover, structural elements for buildings and framework, and all elements for the industry.
