Definitions

  • the present invention relates to a membrane sail hooking device, for a nautical vehicle.
  • the invention also relates to a method of manufacturing such a hooking device as well as a sail equipped with at least one such hooking device. It also relates to a nautical vehicle provided with at least one such attachment device.
  • Sails usually have at their angles (called halyard point, tack point, and clew point in the case of a generally triangular sail) hooking devices formed of a fastening eyelet, for example metallic, intended to receive a "end” (rope) or a shackle.
  • halyard point tack point
  • clew point in the case of a generally triangular sail
  • a sail can include other hooking devices, for example making it possible to take a reef.
  • Boat sails are traditionally made from pieces of sailcloth that are assembled together. These pieces of sailcloth are formed of threads made of twisted fibers, the threads being woven together to form the sailcloth.
  • a second type of laminated sails comprising membranes in which the reinforcing fibers are oriented to measure so as to best take up the forces in order to obtain an efficient shape on the aerodynamic plan, the reinforcing fibers being again coated with glue and deposited between two plastic films.
  • the plastic films in these cases ensure the cohesion of the whole and contribute to the structural strength of the sail in the spaces left free between the fibers.
  • These membranes are then shaped so as to give them a three-dimensional shape by means of the technique known as clamps, in which the membranes are cut into panels each having two edges, each of the edges being able to be curved or straight, one of the edges being subsequently assembled to another of the edges.
  • these laminated webs according to the first or the second type present a high risk of delamination leading to the destruction of the web and a significant heterogeneity in terms of structural strength due to the presence of large gaps between the fibers.
  • the contribution of plastic films to the structural strength of these webs is very low, and the presence of these films brings a very significant additional weight compared to the benefit it provides.
  • these sails can tear quite easily, especially in places with little or no fibers.
  • a third type of web has also been proposed, in which, instead of depositing reinforcing fibers coated with adhesive between the plastic PET films, composite bands are superimposed, each formed of reinforcing filaments embedded in a matrix of resin.
  • the hooking devices such as eyecups, are only added once the sail has been structured, at the different attachment points using sewn straps or blooming fibers glued and sewn. The sail is thus weighed down by the weight of the sewn straps or the open fibers.
  • the membranes are then perforated by seams, which breaks their fibers or filaments and reduces their mechanical properties.
  • the operation carried out in the sailmaker to bring back the attachment devices is long. Indeed, the sail being already structured, it is necessary to unfold it to the less in part, to move it to place the area on which the attachment point is to be attached to a sewing machine. The operation is also expensive.
  • One aim of the invention is in particular to remedy all or part of the aforementioned drawbacks.
  • a fastening device comprising a membrane for a membrane veil, the membrane comprising so-called reinforcing filaments and a resin matrix, which form a surface of membrane work.
  • the attachment device according to the invention is also sometimes called the attachment membrane.
  • a plurality of the reinforcing filaments form a ring arranged outside the work surface, each of the filaments of the plurality of reinforcing filaments having, on the one hand, a part extending outside the work surface.
  • the work surface called the outer part
  • two so-called inner parts each of the inner parts extending at least partially inside the work surface, the outer part being surrounded by two inner parts.
  • the present invention proposes to use fibers present in the membrane and not adding more to form the ring. Good structural strength is thus obtained, weight gain and mechanical stress transmission gain. When we integrate the point of attachment in the membrane, the work is done much more in traction, and it is this stress that we seek to promote because the fibers have high moduli of elasticity.
  • the resin of the matrix can be a thermoplastic resin or a thermosetting resin.
  • the membrane of the attachment device may be in a semi-finished state or else in a finished state after consolidation of the matrix.
  • prepreg is a semi-finished product comprising a resin impregnating a reinforcement. This highly loaded composite is intended for hot molding under pressure by an oven or for being rolled to produce a finished product.
  • the attachment membrane may have a crossing of a portion of the outer part on itself.
  • the fastening membrane can have a crossing of a portion of an interior part over a portion of the other interior part.
  • the attachment membrane may not have a crossing between reinforcing filaments.
  • the fastening membrane may further include a ring reinforcing eyelet.
  • the eyelet is disposed inside the ring formed by the outer portion of the filaments of the plurality of filaments.
  • the eyelet can be metallic, textile or plastic or comprise a plurality of the materials mentioned.
  • the attachment membrane may include means for protecting the exterior part of the plurality of filaments.
  • the means of protection can for example be a sheath, or a very hard resin paint, or else a plastic film.
  • the protection means forms a protective envelope of the outer part of the plurality of filaments.
  • the attachment membrane may include a second outer ring formed of a second plurality of filaments, which extend outside the work surface, between two parts which extend at least partially to the surface. inside the work surface.
  • the second plurality of filaments may include only some, or all, of the filaments of the first plurality of filaments.
  • the second plurality of filaments may not include any of the filaments of the first plurality of filaments.
  • At least one of the filaments of the plurality of filaments extends from an edge of the membrane arranged on the side of the ring to another edge of the membrane. There is then continuity of this at least one filament between the two edges of the membrane.
  • a filament of the plurality of filaments which can extend between two edges of the membrane can further belong to the second plurality of filaments forming the second outer ring when it exists.
  • At least one of the filaments of the plurality of filaments does not extend from an edge of the membrane arranged on the side of the ring to another edge of the membrane.
  • the membrane of the fastening device may be of the type with reinforcing fibers arranged between two plastic films, the reinforcing fibers being at least partially made up of reinforcing filaments.
  • the membranes manufactured by the applicant company are known under the name D4®.
  • the membrane of the attachment device may be of the type of the composite strip type.
  • such membranes are known, manufactured by the applicant company under the trademark DFi®.
  • the filaments of the plurality of filaments of the hooking device may comprise a set of reinforcing filaments, called a primary group, stressed by the primary forces applicable to said web.
  • the reinforcing filaments of the fastening device may comprise a set of reinforcing filaments, called a secondary group, stressed by the secondary forces applicable to said web.
  • the reinforcing filaments of the hooking device comprise a set of reinforcing filaments, called a local group, stressed by the local forces applicable to said web.
  • nautical vehicle provided with at least one membrane sail.

  • a part outside the work surface called the outer part
  • two parts, called interior, inside said work surface each of the interior portions extending at least partially inside the work surface, the exterior portion being surrounded by the two interior portions.
  • a method of manufacturing a membrane sail comprising at least one step of manufacturing a fastening device according to the fourth aspect of the invention.
