Definitions
- the invention relates to the field of methods of manufacturing gliding boards comprising a foam core. It will find an application in particular in the fields of skis, snowboards (snowboards), water skis, “wakeboards", kitesurf boards, surfboards, and sailboards.
- the invention will here firstly be described on the one hand in the context of its application to a kitesurf board, that is to say a board intended to carry the user on the water when he is tow by a kite, and, on the other hand, in the ski area.
- Kitesurf boards have for example dimensions of the order of 120 to 170 cm in length, for widths of the order of 30 to 60 cm, but they are only a few centimeters thick.
- a common method for manufacturing such a type of board is derived from the traditional construction of surfboards.
- a foam bar, produced by molding, is machined (by hand or with a numerically controlled machine) to obtain the shapes of the final core, which core is then covered with a skin.
- This skin is generally made up of layers of reinforcements (such as fiber fabrics) embedded in a resin.
- reinforcements such as fiber fabrics
- a relatively light and rigid composite structure is thus obtained.
- boards of very different characteristics will be obtained depending on the nature of the materials constituting the skins, which can range from a simple sheet of thermoformed ABS resin to a composite sandwich complex passing through the glass fiber / carbon composites. / kevlar embedded in polyester or epoxy resins.
- the core therefore requires long and complex shaping operations, since it often involves producing a final shape in three dimensions essentially comprising curved surfaces.
- this manufacturing requires a long manual operation of finishing the core by planing and sanding.
- these cores are directly molded to the desired shape, either by injection into a mold, or by expansion in the mold.
- the final core is obtained in a simpler and often faster manner.
- the speed of the molding operation is relative insofar as it is necessary to allow the foam time to distribute itself inside the mold and to crosslink. Such a cycle generally requires at least ten minutes.
- Document FR-2,622,810 describes a method of manufacturing ski cores in which a block of polyurethane foam is cut into a parallelepiped shape, then thermoformed so as to obtain the desired thickness at each point of the ski.
- the final density of the core is therefore variable along the ski, and, at each point of the core, it is necessarily inversely proportional to the final thickness of the core at this point.
- the object of the invention is therefore to propose a new method for manufacturing a board which makes it possible to produce foam cores with variable densities in a simple and economical manner.
- the invention provides a method of manufacturing a gliding board, characterized in that it comprises the distinct steps consisting in: - manufacturing a blank of foam core by at least one shaping step by machining; - Carry out a step of shaping the core by thermoforming with compression of the foam blank material; - cover the core with an external skin.
- the invention also relates to a gliding board comprising at least one foam core covered with an outer skin, characterized in that the foam core has at least a first zone and a second zone, the second zone being both more thicker and denser than the first, with no discontinuity of material between said zones.

- FIG. 1 Illustrated in Figures 1 to 3 is an example of a kitesurf board 10, whose external shapes correspond substantially to what can be found on the market.
- the board is essentially flat and thin. However, as can be seen in the side view of FIG. 2, it has a non-negligible longitudinal curvature.
- the lateral edges 12 of the board are arched and the board also has transverse end edges 14 which are arched.
- the board is slightly thicker in its center than near its edges 12, 14.
- the underside 16 of the board, which forms the hull has for example a slight concave which extends longitudinally in its center , the longitudinal edges of the hull being however substantially planar.
- the board is equipped with accessories such as, on its upper face, fasteners for clamping the feet of the user, and, on its lower face, four fins 18 arranged near the four corners of the board.
- the board On the upper face 20, also called bridge, the board has fasteners 22 in which the user can slide his feet in order to drive the board.
- this example of a gliding board is not limiting, and it could have another geometry or be equipped with other accessories, etc.
- the board includes a foam core 24 which is covered with an outer skin 26 and which has zones of different densities without discontinuity of material.
- the principle of the invention is based on the manufacture, from a blank 23, of a core
- thermoformable foam for example a PNC foam such as those sold under the trade name "AIREX”.
- Other materials can be used, and in particular extruded polystyrene foams, and more generally all cellular materials based on synthetic resins.
- a simple shaping operation has been provided by machining the bread 21 in the direction of its thickness. This leads to the blank 23 of the core illustrated schematically in Figure 5 in which we can distinguish for example that the blank has a reduced thickness Hl at its longitudinal ends. This machining operation remains particularly quick and simple because, over a given width, the thickness of the blank is constant.
- This machining operation can be carried out in various ways, and in particular by cutting with a hot wire or by planing.
- This blank 23 can possibly undergo other shaping operations before the thermoforming step with material compression.
- This thermoforming step according to the invention consists in introducing the core blank 23 into the mold of a press (not shown), preferably a heating press.
- the core blank 23 will have been previously heated and brought to a temperature close to the thermoforming temperature of the foam.
- the mold will have preferences for rigid faces.
- the blank is subjected to a compressive force which causes, at least in certain areas, a deformation of the foam by crushing, and the fact that this pressure is applied at a temperature at least close to the thermoforming temperature, this deformation becomes permanent.
- the foam will have definitively taken the shape of the core 24.
- the initial foam bar 21 had longitudinal and transverse dimensions much greater than those of the core 24 so that, after the thermoforming operation, it is necessary to carry out an operation of cutting the core 24 along its contour line C.
- the press mold is provided with sharp edges along this contour line, the cutting operation then being carried out simultaneously with that of thermoforming.
- the blank 23 has a contour sufficiently close to that of the core so that no cutting is necessary.
- the core was produced in a press which can move only in one direction, in this case along the direction of the thickness of the blank 23 and of the core 24.
- thermoforming step with compression of material to be carried out in several progressive substeps, these different substeps using for example molds different.
- the different zones of the foam core will thus each have undergone a force and a compression amplitude which depends essentially on the initial thickness of the blank in this zone and on the final thickness imposed by the corresponding faces of the mold in closed position.
- a force and a compression amplitude which depends essentially on the initial thickness of the blank in this zone and on the final thickness imposed by the corresponding faces of the mold in closed position.
- tests have shown that, under the above conditions, it was possible to locally reduce the thickness of the foam to less than a quarter of its initial thickness, that is to say by multiplying its density by at least a factor of 4, without the foam being damaged.
- the foam thus densified is more resistant, both in flexion and in compression.
- thermoforming step according to the invention may very well leave certain areas of the blank of the core perfectly intact, without any deformation. Similarly, it may also impose, in certain areas, geometric deformations which do not cause significant compression of the material. Certain zones can thus be bent only by thermoforming, which, especially for thin parts, hardly involves any compression of the material. As illustrated in FIGS. 10 to 12, the invention will also be particularly useful for locally reinforcing other zones of the board than the peripheral zone, in particular the zones which are intended to receive accessories such as the fixings 22 or the fins. 18.
- the core blank can include extra thicknesses (in the direction of compression provided for the shaping step) corresponding to the zones of the core in which the foam is to be densified.
- extra thicknesses in the direction of compression provided for the shaping step
- it is chosen to densify the areas of the boards intended to receive the fasteners 20.
- these core areas of boards should firstly allow solid anchoring of the fasteners, and secondly they should directly support the pressure forces due to user support. It is therefore particularly interesting to strengthen them. Thanks to the invention, this is achieved in a particularly simple manner.
- extra thicknesses 28 are provided in the blank, in the areas to be densified.
- the core illustrated in FIG. 12 is effectively reinforced in the predefined areas. This local reinforcement will allow the insertion of inserts in the core, which allow the anchoring of the fasteners.
- the same technique of local densification of the core could for example be used to create in the core “stiffening beams”, directly integrated into the core, without discontinuity of material.
- the core For example, if one wishes to increase the rigidity of the torsional board, provision could be made for the core to have diagonal beams, each joining two opposite corners of the board. We can also create in the core a central longitudinal beam, well known in the field of manufacturing surfboards. Finally, the thermoforming technique with material compression can also be used to create simple hollow and / or raised decorative patterns, for example on the upper face of the board. Thanks to the invention, it is therefore possible to densify and locally strengthen the core, exactly where it is necessary. Unlike certain cores of the prior art in which local reinforcements are integrated in the form of inserts made of a material different from the base material of the core, the technology according to the invention makes it possible to maintain continuity of the material of the core between the sparse areas and denser areas.
- the shape of the core 24 can also be corrected after the thermoforming step by a complementary operation, for example by shaping by machining, therefore by removing material.
- the initial density of the core foam will of course be chosen as a function of the final characteristics desired for the gliding board, in particular the desired stiffness and solidity.
- the weight / volume ratio targeted for the board will also be taken into account, especially if precise characteristics in terms of buoyancy are desired.
- the possibility of densifying the foam selectively will make it possible to maintain a low density of foam in the least stressed areas.
- the gliding board has only one core. However, for various reasons, it can be envisaged to use several cores, for example two superimposed cores.
- these two cores can be separated for example by a reinforcing layer such as a sheet of fiber fabrics impregnated with resin, a metal strip, etc.
- a reinforcing layer such as a sheet of fiber fabrics impregnated with resin, a metal strip, etc.
- the manufacture of the board can be continued according to the usual techniques. All the usual materials can be used to make the skin intended to cover the core. This skin to contain, for example, a simple sheet of thermoformed ABS resin, a composite sandwich complex, glass / carbon / kevlar fiber composites embedded in polyester or epoxy resins.
- the skin may also include localized reinforcements such as very high density foams, cellular materials of the honeycomb type, etc.
- the board may also be provided, along its edges, with a peripheral reinforcement 30 made of plastic, for example ABS.
- a metal reinforcement is for example produced in the form of an aluminum alloy sheet that is a few tenths of a millimeter thick.
- This metal sheet covering for example the upper surface of the board, is embedded in a resin (preferably thermosetting). To reduce its weight, provision may be made for it to have recesses, for example holes regularly distributed over its entire surface.
- FIG. 13 an embodiment has been illustrated in the invention has been used to create a reinforcement of the density of a ski core 24 in its central part 32 (or platform, that which is intended to receive the system binding), and in zones forming “stiffening beams” 34 in X which, starting from the center of the core of the ski, extend in the direction of the front and rear lateral ends.
- kitesurfing one could choose to strengthen the periphery of the core.
- the core of FIG. 13 is easily obtained thanks to the invention by machining a core blank so that it has extra thicknesses of the shape corresponding to said zones.
- the final core may, as desired, have extra thicknesses in the areas thus densified, or on the contrary have a “smooth” upper face.
- a ski core 24 having a raised and densified central platform 32, as well as, in front and behind this platform 32, two beads 36 semi cylindrical which extend parallel to each other in a substantially longitudinal direction on the upper surface of the core.
- a core illustrated schematically and partially in FIG. 15, can be obtained by starting from a machined blank 23 as shown in FIG. 14.
- This blank 23 has a very thick central portion 38, and, longitudinally from the side and d 'other, front 40 and rear 42 portions having a substantially rectangular section whose height corresponds for example substantially to the height of the beads 36 of the core final.
- the central platform 32 is very dense (FIG.
- the front 40 and rear 42 portions of the core are not very dense at the level of the beads 36, and more dense between the beads 36 and, on either side of these, on the side edges ( Figure 16).
- Figure 18 there is illustrated a core 24 of snowboard having a lateral side 44 where the density of the foam is greater than at the opposite lateral side 46. Thanks to the invention, this can be easily obtained by machining a core blank 23 having the profile illustrated in cross section in Figure 19, where one side is thicker than the other.
- a core is obtained, for example of constant thickness (cf. FIG. 20), which has a density gradient in the direction of its width.
- a core is obtained, for example of constant thickness (cf. FIG. 20), which has a density gradient in the direction of its width.
- a snowboard core it is of course also possible to densify the core at the areas intended to receive the bindings, as seen more in the case of the kite-surfboard.
- the lateral asymmetry described here can of course be declined in longitudinal asymmetry, or others.
- the various variants which have just been mentioned can of course be declined and used whatever the gliding board envisaged, and they can generally be combined with one another.
- a core produced according to the invention can be used with most of the known methods and constructions, in particular in the field of skiing and snowboarding (sandwich construction, “cap” construction, “hull” construction, etc.).
- the method according to the invention could moreover be very advantageously used for the production of foam cores provided with inserts.
- the principle is schematically described in FIGS. 21 to 23. For example, one wishes to integrate, completely or partially, an insert 48 (made of wood, or plastic, composite material, metal, etc.) in a foam core 24.
- This insert 48 may for example be intended to form an anchoring reinforcement intended to receive screws for anchoring a fixing system, and it is intended to be received (at least partially) in a housing 50 of corresponding shape arranged in the foam core 24 (see Figure 22).
- the housing 50 is produced according to the invention by thermoforming with compression of material.
- Housing can be achieved in two ways. First of all, it can be produced by means of an adapted form of the thermoforming mold. In this case, from a blank 23 as illustrated in FIG. 21, the core of FIG. 22 is obtained. Here, the blank the insert and the core have very simple geometric shapes, but the realization housing by thermoforming will be all the more interesting as the shapes of the insert (and therefore of the housing 50) will be complex.
- the insert is placed inside the thermoforming mold (for example by being pressed against the mold cover), and that the insert itself forms the housing in which it should fit.
- This embodiment guarantees a perfect adaptation of the shape of the housing to that of the insert.
- the insert is used as a thermoforming tool to form the housing.
- the insert is itself heated to the thermoforming temperature or to a close temperature (provided that it withstands such a temperature without losing its mechanical characteristics, since it must, in this embodiment, withstand the effort necessary to compress the foam of the core).
- the face or faces of the insert which are in contact with the core is provided with an adhesive, or even with a fiber reinforcement impregnated with resin.
- thermoforming of the foam core with material compression makes it possible to best exploit the great flexibility of use of the foams and to reinforce by the same operation the mechanical characteristics of the core. in the desired location, starting with a foam bar of uniform density.
- the fact of providing a machining step by removing material from the core blank will make it possible to distribute, with great precision and with total freedom of design, the quantity of material of the core. This makes it possible in particular to obtain, in the same core, zones which are both thick and dense or both thin and not very dense, without discontinuity of material.
- skis For example, for the manufacture of skis, it is possible to have a thick and dense central zone, favorable to reliable anchoring of the binding system, and thin and not very dense ends, therefore particularly light, making it possible to reduce the inertia of the skis. rotational movements.
