Definitions

  • the invention relates to the field of floats gliding on water, such as surf floats or windsurfing.
  • a surf float is made from a foam roll, including rigid polyurethane foam, which is formed in a mold.
  • the foam roll is machined by planing and sanding to locally customize its shape and form the float's novan.
  • This core is then coated with a resin-impregnated glass fiber shell which forms an outer reinforcing shell and gives the float its final shape and mechanical strength.
  • a decoration and an icing give the float its final appearance.
  • the core is cut longitudinally into two parts which are then glued against a wooden lath which reinforces its structure.
  • the foam is relatively dense: typically its density is 50 kg / m3. And it is not possible in principle to reduce the density of the foam without affecting the mechanical characteristics of the float.
  • the float In the field of "bodyboard” boards, the float is essentially composed of elastic foam (possibly by combining several layers of different densities and characteristics), without the presence of an envelope with high mechanical characteristics. In some cases, these floats are provided with a lower layer of thermoformed plastic to ensure better glide on the water.
  • these boards are generally relatively flexible because the user must be able to deform them in use to maneuver at best. Unlike surfboards and windsurfers, where the user is standing, boogie boards must not withstand great effort because the user uses them while lying on the surface of the water, with only his bust resting on the board.
  • a rigid foam roll of relatively low density for example an expanded polystyrene foam of 18 kg / m3 that is machined so as to shape it, or mold directly to the shape of the float core.
  • This core is covered with an outer shell, which may comprise a resin-impregnated glass fiber skin, and / or a sheet of thermoformed plastic material, and / or a sandwich structure.
  • Such a construction method can allow weight gain while maintaining good rigidity, especially when using a sandwich structure envelope, that is to say a structure comprising a low density layer (usually PVC foam or extruded polystyrene) between two thinner layers with high mechanical properties (especially resin-impregnated fibers).
  • a sandwich structure envelope that is to say a structure comprising a low density layer (usually PVC foam or extruded polystyrene) between two thinner layers with high mechanical properties (especially resin-impregnated fibers).
  • Such a construction when it makes use of sandwich structures, makes it possible to obtain stiff boards, therefore
  • the float is composed of a central core made of a first cellular material, which is covered with a layer of rigid cellular material, denser and more resistant, itself covered with an outer skin (thermoformed plastic sheet or layer of fibers coated with resin, cf. WO-82/04023 or DE-33.11.734 ).
  • floats which comprise a rigid internal structure covered with an outer layer of flexible foam, which determines the external shape of the float (cf. US 3543315 or US 5489228 ).
  • These floats are generally very comfortable in navigation but, their weight is too important and the flexibility of the outer shell does not give good results in terms of nervousness and precision driving the board.
  • the layer of flexible foam is only covered with a plastic film or a flexible coating having no notable mechanical strength and whose only role is to protect the flexible foam abrasion and improve the slips.
  • floats which have a different structure on the hull and on the deck.
  • a float comprising a foam core which is covered with an envelope.
  • the envelope On the deck, the envelope is a rigid sandwich structure while on the hull, the envelope is a single layer of resin impregnated fibers.
  • the hull of the float In the document FR-2612874 , the hull of the float is covered with a thin layer of elastic material so as to impart shock absorption properties.
  • the document DE-32.06.334 it is the deck of the float which is covered with a layer of elastic material. In the last two cases, the layers of elastic material are directly exposed to the outside.
  • the float envelope comprises a layer of resin-impregnated fibers associated with a layer of damping material.
  • the damping layer is arranged outside with respect to the resin-impregnated fiber layer.
  • the damping layer may be arranged either only on the deck, or on the deck and on the hull. This document does not plan to use a sandwich structure envelope.
  • the object of the invention is to propose a new construction optimized for the production of a gliding float, particularly for the practice of surfing or windsurfing, which is particularly optimized to guarantee ease of implementation suitable for to allow a low cost, a limited float final weight, a sufficient overall stiffness to obtain an adequate level of performance, and a certain comfort of use, without sacrificing either the float's driving precision, or its solidity.
  • the invention proposes a float for sliding on the water, of the type comprising a core covered by an outer shell forming a bridge and a hull, of the type in which the outer envelope comprises at least one bridge portion and one hull portion, of the type in which at least the bridge portion of the envelope comprises a sandwich structure comprising at least a central layer of low density between two layers of finer and high mechanical characteristics, and of the type in which the layers at high Mechanical performances comprise resin-impregnated fiber plies, characterized in that the low density central layer of the sandwich structure of the bridge portion comprises a flexible and elastic cellular material.
  • a float glide on water of the type comprising a core covered by an outer casing forming a bridge and a hull, of the type in which the outer casing comprises the at least one bridge portion and one hull portion, both made in the form of a sandwich structure composed for each of the parts of at least one central layer of low density between two layers with finer and high mechanical characteristics, of the type in wherein the high mechanical performance layers comprise resin impregnated fiber plies, characterized in that the low density core layer of the hull portion is made of rigid cellular material while the low density core layer of the bridge portion comprises a flexible and elastic honeycomb material.
  • FIG 1 there is illustrated the general external shape of a float glide on the water 10, for example a surf float.
  • the float comprises a core 14 arranged inside an outer casing 12.
  • the outer casing 12 forms; in its upper part, the bridge 16 of the float on which the user is intended to bear, and in its lower part, the hull 18 which is supported on the water.
  • the peripheral side edge of the outer envelope defines the float rails.
  • this outer envelope defines, in a sealed manner, an internal space of the float which is wholly or partially filled by the core 14.
  • an expanded polystyrene foam of very low density for example of a bulk density of less than 25 kg / m3 or even equal to or less than 18 kg / m3.
  • the core 14 may also include localized reinforcements particularly resistant material, extending over the entire height of the internal space defined by the envelope, or only a portion of this height. An embodiment of such a core will be described below with reference to FIG. 4.
  • the core 14 completely fills the internal space of the float.
  • the presence of hollow zones will of course have a favorable influence on the weight of the float and their distribution will influence the moment of dynamic moment of inertia of the float, which will influence its behavior on the water, notably its response to the different supports and changes of directions. imposed by the user.
  • the core 14 illustrated in the figures is monobloc and composed of a single material. However, it could be expected that the core is composed of several elements, possibly made of different materials.
  • the core is pierced with lightening holes. Similar methods for lightening the core, such as those described in the documents FR-2820712 , FR-2820713 , and FR-2820714 may advantageously be used in the context of the present invention.
  • the two parts (bridge and hull) of the envelope have a sandwich construction in which a layer of low density material, forming the core 24, 25 of the sandwich structure, is imprisoned between two inner and outer layers 26 of reinforcing material which form the skins of the sandwich and which comprise, for example, layers of fibers embedded in a resin, for example an epoxy resin.
  • the nature of the fibers may be identical or different for the inner layer or for the outer layer.
  • it may differ between the hull portion and the bridge portion, that is to say that it may for example be provided that the inner layer of the bridge portion comprises aramid fibers while the inner layer of the hull portion would include carbon fibers.
  • the layers of fibers may be woven or non-woven, unidirectional or multidirectional. For the simplest and most economical constructions, the layers of fibers will be fiberglass fabrics.
  • the two parts of the bridge and hull of the envelope differ in the nature of the material which constitutes the core 24, 25 of their sandwich structure.
  • the layer of low density material 25 consists of one or more materials described as "rigid", while in the bridge portion the The low-density material layer 24 comprises, according to the invention, at least one part made of a flexible cellular material.
  • the low density materials will preferably be cellular materials, including foams of plastics.
  • Rigid foams have a low elasticity in that as soon as the compression force exceeds a certain value, they deform by collapse, irreversibly or very little reversible.
  • Rigid foams include polyurethane foams and extruded polystyrene or expanded polystyrene foam which are generally used in the form of foam bars to form the cores of traditional surfboards.
  • some PVC or polyimide foams commonly used as core in sandwich structures are considered rigid materials. Although called rigid, these foams can, in the lowest densities, be quite easily compressible (and therefore appear soft), but they have a very low elasticity.
  • resilient plastic foams of elastic nature are known, such as foams of expanded polyolefins, especially polypropylene or polyethylene.
  • expanded polypropylene foams it is possible, for example, to use grades having apparent densities of between 20 and 100 kg / m 3. These materials generally have a stress at 25% of compressive strain of the order of 100 to 600 kPa.
  • the principal elements of choice of the material will be its stiffness to the compression, but still more its capacity of elastic deformation (the material will preferably have to recover its initial form after a compression of the order of 25%), and its capacity of restitution of the energy absorbed during compression.
  • the rigid foam 25 may be replaced by a honeycomb structure, or by a light wood layer.
  • the hull portion of the envelope may have another structure. It may be a single layer of fibers impregnated with resin, or an intermediate layer of a light and rigid material (rigid foam, light wood, etc.) covered with a layer of fibers impregnated with resin.
  • the outer skin 28 is then stressed both in flexion and in traction along its plane, like a trampoline.
  • the outer skin 28 of composite material allows a much greater energy return than the simple springback of an elastic material that would be disposed on the deck of the float and which would be compressed vertically.
  • the "trampoline” effect with a strong elastic component, can be opposed to a simple "mattress” effect which is essentially damping, and which therefore tends to restore only a small part of the energy that is communicated to it. .
  • the trampoline effect makes driving the float much more lively.
  • this effect of deformation / restitution of the outer skin 28 of the sandwich is perfectly reversible (at least up to a certain limit that can be determined for example by varying the thickness and stiffness of the outer skin 28 and / or by varying the stiffness of the elastic flexible material forming the core 24 of the sandwich structure) and it takes place without causing significant deformation of the core 14, thanks to the presence, under the flexible and elastic layer, of the layers
  • This fiber in addition to its own mechanical strength, makes it possible to distribute over a large area the stresses transmitted to it.
  • the elastic core sandwich construction allows the bridge to better withstand shocks and driving effects.
  • the resin of the outer skin for example an epoxy resin
  • the resin of the outer skin may optionally be mixed with compounds which improves its flexibility.
  • the flexible foam layer 24 which forms the core of the sandwich structure of the bridge extends down along the lateral edges of the float. This allows in particular to benefit from the best impact resistance of this structure in a particularly exposed area.
  • it is the sandwich structure of the hull that rises along the side edges, that the two structures meet at the point of greater width, or that the side edges have a clean structure.
  • the outer casing 12 can be made in the form of two prefabricated half-shells, forming respectively the bridge and the hull, the half-shells being assembled to one another, for example by gluing along their plane of join, to form a sealed outer envelope.
  • the two half-shells can be joined to each other before the outer reinforcing layer is applied to the core-forming layer of the sandwich.
  • Such a process is similar to that described in the document WO-02/10011 , to which we will usefully refer, and has the advantage of allowing the opportunity to rework the layer forming the core of the sandwich, after the assembly of the half-shells, but before the laying of the outer layers of the sandwich, in order to customize the shape of the float, if this is desirable.
  • all the components can be assembled and shaped under pressure in a mold according to the technique usually used for the manufacture of windsurfing floats sandwich type.
  • the outer casing 12 furthermore has an external protection made in the form of a sheet of thermoformed thermoplastic material 30.
  • This protective layer 30 is translucent example and it can be decorated. The decoration will advantageously be arranged on the face of the sheet which is turned towards the inside and it may be made for example by screen printing or by sublimation. It is also conceivable to incorporate a decorative element between the outer skin 28 and the protective sheet.
  • the protective sheet will for example be made of a material comprising a mixture of ABS and polyurethane, and having a thickness of the order of 0.3 mm.
  • the sheets of protections could be different for the deck and for the hull. It can also be envisaged that such a protective layer is disposed only on one side of the float, for example the bridge.
  • FIG. 4 an embodiment of a reinforcement 32 is illustrated.
  • This reinforcement 32 is simply composed of a sheet of resin-impregnated fibers folded on itself to form a T whose vertical leg 34 is inserted in a groove 36 formed in the core 14, and whose horizontal portion 38 rests against an upper face of the core 14.
  • a rectilinear groove 36 substantially perpendicular to the outer face of the core.
  • the sheet of resin impregnated fibers (not yet polymerized, therefore still flexible) is folded in half and inserted at the bottom of the groove 36. The parts of the sheet which protrude outside are then folded against the outer face of the groove. core.
  • the reinforcement 32 forms a rigid T-shaped section that is integrated into the core 14.
  • the vertical portion 34 of the T gives it a very good stiffness in flexion, while the horizontal portion 38 forms a kind of plate that allows to distribute the pressures exerted locally by the outer casing 12 on the core 14.
  • this reinforcement 32 is particularly judicious deck side of the float, because it reinforces the core where the high pressures exerted by the user's support are exerted .
  • Figure 1 there is illustrated a possible arrangement, with two reinforcements 32 disposed on the bridge, each of a median longitudinal axis of the board.
  • the reinforcement 32 is placed on the core 14 naked. However, to facilitate the operation, it may be preferable to set up the reinforcement after The main difference will be that the horizontal portion 38 of the reinforcement T will then be arranged between the inner skin 26 and the low density layer 24, 25.
  • the construction according to the invention therefore makes it possible to produce a float having a perfect compromise between ease and precision of driving, comfort and performance, all with a perfectly industrial process allowing relatively low costs.
