Abstract

The invention discloses composite material tubes, piles, masts subjected to axial compression or bending stresses, produced by an adapted winding of weft-unbalanced woven fabric, such that the main portion of reinforcement fibres is placed parallel to the longitudinal axis of the structure. The tubes, piles and masts are produced by winding on a compressible mandrel to ensure that the tubes are not stressed or subjected to micro-cracking when the mandrel plug is pulled out.

Description

EQUIPEMENT TUBULAIRE EN MATERIAUX COMPOSITES TUBULAR EQUIPMENT IN COMPOSITE MATERIALS
REALISES PAR ENROULEMENT DE TISSUSMADE BY WINDING FABRICS
DESEQUILIBRES EN TRAME SUR UN MANDRIN COMPRESSIBLEWEFT IMBALANCES ON A COMPRESSIBLE CHUCK
i De nombreux équipements, en particulier des pieux et des mâts, sont réalises en acier et présentent, de ce fait, des inconvénients, tels que a) leur masse élevée et dans certains cas des difficultés logistiques de mise en place b) leur sensibilité à la corrosion qu'elle soit aérienne, aquatique ou terrestre c) leur coût d'entretien lo Pour repondre, en particulier a ces inconvénients, de tels équipements ont ete réalises en aluminium ou en matériaux composites Dans le cas de ces équipements en matériaux composites, la technique généralement utilisée est celle de l'enroulement filamentaire de rowingi Many pieces of equipment, in particular piles and masts, are made of steel and therefore have drawbacks, such as a) their high mass and in some cases logistical difficulties in setting up b) their sensitivity to corrosion, whether aerial, aquatic or terrestrial c) their maintenance cost lo To respond, in particular to these drawbacks, such equipment has been made of aluminum or composite materials In the case of such composite material equipment, the technique generally used is that of the filament winding of rowing
Les équipements, tels que les pieux et les mâts, doivent avoir non seulement de l ^ bonnes caractéristiques a la rupture, mais aussi présenter une bonne rigidité sous les effets d'un mouvement fléchissantEquipment, such as piles and masts, must not only have good breaking characteristics, but also have good rigidity under the effects of a bending movement.
Pour cela, il faut que la structure composite profite pleinement, d'une part de la résistance a la rupture en traction et en compression des fibres, et d'autre part, du module de flexion des fibres renforçatπces Ainsi, tl faut que la partie principale de celles-ci soit placée 2<ι selon l'axe du pieu ou du mâtFor this, the composite structure must take full advantage, on the one hand of the tensile and compressive strength of the fibers, and on the other hand, of the flexural modulus of the reinforcing fibers. Thus, the part main of these is placed 2 <ι along the axis of the stake or mast
Selon l'invention, les structures allongées, telles que des mâts pieux, des poutres sont réalisées par enroulement, preferentiellement hélicoïdal, de tissus de verre imprègnes de résine thermodurcissable, telle que epoxyde, polyester, vinylesterAccording to the invention, the elongated structures, such as pious masts, beams are produced by winding, preferably helically, of glass fabrics impregnated with thermosetting resin, such as epoxide, polyester, vinylester
Selon l'invention, ces tissus sont déséquilibres en trame, c'est a dire, ont un 2^ pourcentage plus important de fil en trame qu'en chaîne , de plus, leur tissage admet une déformabihte angulaire qui permet, selon l'invention, de placer les fils de trame parallèlement a l'axe x x' de la structureAccording to the invention, these fabrics are imbalanced in the weft, that is to say, have a 2 ^ higher percentage of yarn in the weft than in the warp, moreover, their weaving admits an angular deformation which allows, according to the invention , to place the weft threads parallel to the axis xx 'of the structure
L'originalité de la conception de ces tubes composites a haute tenue a la flexion objet de la présente invention, ressortira de sa description et de la |ustιfιcatιon technique "o correspondanteThe originality of the design of these composite tubes with high resistance to bending, object of the present invention, will emerge from its description and from the corresponding technical or "technical"
Selon l'invention, on réalise donc le tube par enroulement hélicoïdal d'un tissu de verre déséquilibre c/t avec c<t Conformément aux habitudes, c indique le pourcentage de fibre placées en chaîne et t le pourcentage de fibre placée en trame On prendra preferentiellement c compris entre 10 et 25 % et t entre 90 et 75 % , cette modulante du taux permet, en fonction du rapport diamètre/épaisseur, d'assurer une bonne tenue au flambage radialAccording to the invention, the tube is therefore produced by helical winding of a glass fabric imbalance c / t with c <t In accordance with usual practice, c indicates the percentage of fiber placed in warp and t the percentage of fiber placed in weft On preferentially take c between 10 and 25% and t between 90 and 75%, this modulating rate allows, depending on the diameter / thickness ratio, to ensure good resistance to radial buckling
Selon l'invention, le tube est constitué de couches successives réalisées par enroulement hélicoïdal - aller et retour -. L'enroulement hélicoïdal se fait à l'aller avec un angle de β 1 = (90°- α) par rapport à l'axe longitudinal et au retour avec un angle de β2 = (90° + α).According to the invention, the tube consists of successive layers produced by helical winding - back and forth -. The helical winding is done on the outward journey with an angle of β 1 = (90 ° - α) relative to the longitudinal axis and on the return journey with an angle of β2 = (90 ° + α).
Selon l'invention, l'enroulement hélicoïdal est fait preferentiellement en biaisant le tissu d'un angle α (fig.1) de telle façon que la trame (1) soit parallèle à l'axe longitudinal du tube, la chaîne (2) présentant un angle α par rapport au plan circonférentiel (3), cette disposition améliore le module de flexion.According to the invention, the helical winding is preferably made by biasing the fabric at an angle α (fig. 1) so that the weft (1) is parallel to the longitudinal axis of the tube, the warp (2) having an angle α with respect to the circumferential plane (3), this arrangement improves the flexural modulus.
Selon l'invention, l'enroulement de chaque couche est fait preferentiellement par recouvrement partiel (6) des spires successives (4)(5) (fig.2) Pour éviter les surépaisseurs locales, la largeur du décalage I entre deux spires successives est telle queAccording to the invention, the winding of each layer is preferably made by partial covering (6) of successive turns (4) (5) (fig. 2) To avoid local excess thickness, the width of the offset I between two successive turns is such as
L n avec L largeur de la nappe et n un nombre entier >1L n with L width of the tablecloth and n an integer> 1
Sans sortir de l'invention, l'enroulement hélicoïdal est fait soit avec des lés jointives (7) (fιg.3), soit avec des lés alternées (fig.4). Les lés (8) et (9) sont placés lors du 1er aller Les lés (10) et (1 1) lors du 1 er retour , les lés (12) et (13) lors du 2ème aller. Ce dernier type d'enroulement améliore la tenue aux efforts de cisaillement inter laminaire.Without departing from the invention, the helical winding is made either with contiguous strips (7) (fιg.3), or with alternating strips (fig. 4). The strips (8) and (9) are placed on the 1st outward journey. This latter type of winding improves the resistance to inter-laminar shear forces.
Selon l'invention, dans le cas d'un enroulement à spires jointives, les couches successives seront preferentiellement décalées pour diminuer l'effet de discontinuité provoqué par les lés. Par exemple, dans le cas d'un enroulement hélicoïdal à lés jointives de largeur L et de nombre de couches q, l'implantation de chaque couche (aller + retour) est décalée d'un espace de largeur K tel queAccording to the invention, in the case of a winding with contiguous turns, the successive layers will preferably be offset to reduce the discontinuity effect caused by the strips. For example, in the case of a helical winding with joined strips of width L and number of layers q, the implantation of each layer (go + return) is offset by a space of width K such that
L K = ~ m avec m entier >1 et si possible avecL K = ~ m with integer m> 1 and if possible with
m ≈ 3 r r étant un entier (fig.5).m ≈ 3 rr being an integer (fig. 5).
Les lés (14) (15) (16) sont les lés du 1er aller et les lés (17) (18) (19) sont les lés du 2ème aller Si le tissu preferentiellement utilisé est un tissu en fil de verre, on peut, sans sortir de l'invention, utiliser des tissus en carbone, aramide, polyéthylène haute résistance OnThe tapes (14) (15) (16) are the first tapes and the tapes (17) (18) (19) are the second tapes If the fabric preferentially used is a glass fiber fabric, we can , without departing from the invention, use fabrics made of carbon, aramid, high-resistance polyethylene On
FEUILLE DE REMPLACEMENT (RÈGLE 26) peut aussi utiliser des tissus hybrides (ex : verre + carbone).SUBSTITUTE SHEET (RULE 26) can also use hybrid fabrics (ex: glass + carbon).
Sans sortir de l'invention, les tissus utilisés peuvent être préimprégnés de résine thermodurcissable.Without departing from the invention, the fabrics used can be pre-impregnated with thermosetting resin.
Sans sortir de l'invention, les tissus utilisés peuvent être préimprégnés de résine thermoplastique.Without departing from the invention, the fabrics used can be pre-impregnated with thermoplastic resin.
Sans sortir de l'invention, les tissus peuvent être enroulés en même temps qu'un film thermoplastique et imprégné par fusion compression.Without departing from the invention, the fabrics can be wound at the same time as a thermoplastic film and impregnated by compression compression.
Dans le cas, où l'on réalise des équipements tels que des pieux ou des mâts de fortes épaisseurs, comportant des parties cylindriques et présentant un déséquilibre de renfort de fibres selon l'axe x x' de l'équipement, on constate, après polymérisation, des forces de serrage importantes de la structure composite sur le mandrin ; ce phénomène peut rendre difficile ou empêcher le démandrinage et créer des micro ruptures dans la structure.In the case where equipment such as piles or masts of large thickness is produced, comprising cylindrical parts and having a fiber reinforcement imbalance along the axis xx 'of the equipment, it is found, after polymerization , large clamping forces of the composite structure on the mandrel; this phenomenon can make it difficult or prevent leaning and create micro-ruptures in the structure.
Pour éviter ces inconvénients majeurs, selon l'invention, on place sur le mandrin une couche régulière de matériaux compressibles, puis on enroule le tissu de verre sur ce mandrin compressible.To avoid these major drawbacks, according to the invention, a regular layer of compressible materials is placed on the mandrel, then the glass cloth is wound on this compressible mandrel.
Selon l'invention, les caractéristiques de compressibilité du matériau seront telles que sa déformabilité restera faible sous l'effort limité d'enroulement du tissu et absorbera le rétreint de la structure composite en ne transmettant au mandrin qu'un faible effort de serrage, facilitant aussi le démandrinage Selon l'invention, le matériau choisi aura un coefficient de frottement faible.According to the invention, the compressibility characteristics of the material will be such that its deformability will remain low under the limited effort of winding the fabric and will absorb the constriction of the composite structure by transmitting to the mandrel only a slight clamping effort, facilitating also the mandrel according to the invention, the chosen material will have a low coefficient of friction.
Selon l'invention, le matériau est preferentiellement une mousse de polyéthylene à cellule fermée avec une peau glacée.According to the invention, the material is preferably a closed cell polyethylene foam with an icy skin.
Sans sortir de l'invention, on pourra utiliser un autre matériau présentant les caractéristiques ci-dessus, par exemple des mousses de polyuréthanne souples. Selon l'invention, afin de faciliter le démandrinage et l'état de surface interne du tube, on revêtira la mousse d'un film de terphane.Without departing from the invention, it is possible to use another material having the above characteristics, for example flexible polyurethane foams. According to the invention, in order to facilitate the mandrel and the internal surface condition of the tube, the foam will be coated with a film of terphane.
Dans le cas où les efforts de flexion seraient préférentiels selon une direction radiale privilégiée, selon l'invention on réalisera des tubes de forme oblong (fig.6). Ce type de tube peut s'appliquer par exemple à la réalisation de brise vague. Sans sortir de l'invention, le tube peut être un tube sandwich (fig .7) constitué par deux tubes concentriques (20,21 ) réalisés selon l'invention et séparés par une paroi (22) en matériau rigide en compression tel que : mousse rigide, nid d'abeille, balsa ... Cette solution permet d'alléger les tubes et d'améliorer la rigidité. Sans sortir de l'invention, pour améliorer la rigidité en cas d'effort de flexion selon tube intérieur pourra être cylindrique et le tube extérieur oblong In the case where the bending forces would be preferential in a preferred radial direction, according to the invention, tubes of oblong shape will be produced (fig. 6). This type of tube can be applied for example to the production of a wave breaker. Without departing from the invention, the tube can be a sandwich tube (fig. 7) constituted by two concentric tubes (20,21) produced according to the invention and separated by a wall (22) made of rigid material in compression such as: rigid foam, honeycomb, balsa ... This solution makes it possible to lighten the tubes and improve rigidity. Without departing from the invention, to improve the rigidity in the event of bending stress according to inner tube may be cylindrical and the outer tube oblong
