Definitions
- the present invention relates to the field of composite material parts, comprising a thermoplastic or thermosetting matrix reinforced with fibers, such as, without limitation, fittings.
- fiber all the forms in which the reinforcing fibers may be presented, and in particular, but not exclusively, reinforcing strands, ribbons or cords of fibers.
- Such composite material parts such as those described in documents DE 29 45 469, FR 3032144, DE 102010025940 and WO 2015/066407 for example, have a lattice structure obtained by winding fibers impregnated with resin on a frame of which protruding studs, so as to allow to walk and stretch the fibers between said pads to orient them preferentially according to the directions of stress.
- the fibers extend in substantially parallel or perfectly parallel planes, as in document WO 2015/066407, with the result that the lattice structure obtained can not respond optimally to solicitations exercised in directions other than those parallel to those plans.
- the reinforcing fibers have shown their effectiveness in the ability to achieve mechanical structures both resistant and light. This efficiency is due to the fact that the bars constituting the lattice are stressed in tension or compression, stresses particularly suited to present uniform stresses in the straight sections of the bars.
- the compressive strength of the fibers is more modest than the tensile strength thereof, particularly because of the problem buckling of the fibers in compression, global or local buckling of the fibers.
- the fibers are arranged in a lattice shape in a first preform, which is compacted to form a second moldable preform.
- the compaction phase induces the non-straightness of the bars forming the lattice.
- the crushing of these bars in their end creates complex shapes to induce parasitic stresses in the bars.
- the fibers are either overstretched, which causes significant internal stresses in the final part, or underlying what generates their pleating.
- the fibers In order to be able to apply thin fibers in compression, the following three conditions must be respected: that the fibers be perfectly rectilinear, that they be locked in their deformation or displacement transverse (e) to their main direction, and that the introduction the mechanical action in the fibers is done without introducing any unwanted stress.
- the compression of the fibers tends to separate the knot.
- the curved shape of the fiber due to the crossing thereof promotes the local bending of the fiber placed in compression and thus the overall buckling of the fiber.
- the object of the present invention is to remedy the various aforementioned drawbacks, by proposing a method of producing a composite material part, and more particularly of producing the lattice structure of a piece of material composite, respecting the three conditions previously defined, and the resulting part, so that the latter has a mechanical strength in compression.
- the method of producing a composite material part consists of adding a thermoplastic or thermosetting matrix around a preform consisting of a reinforcement fiber mesh made by filament winding around the pins or the like. a chassis, and it is characterized in that it consists in winding the fibers further on one or more coils internal to the matrix, the axes of said pins or the like and those of said one or more coils, being of different orientations, so as to confer on said fiber lattice a three-dimensional shape.
- windings are made between pairs of internal coils to form bars constituting the lattice structure.
- the windings between two coils of a pair of coils are made by passing one side or the other of the one and / or the other coil, so that to create, within the bar which connects said two coils, at least one cross fiber.
- one or more complete windings are made around the coil.
- one or more complete consolidation windings are made around the coil between the fibers which form the bars, during and / or after the creation windings of said bars have been produced.
- thermoplastic matrix or thermosetting around the preform is carried out either by dipping, by spraying, or overmolding.
- the coils may also constitute interfaces forms of the final part.
- the internal coil or coils can create intermediate nodes, allowing a change of direction of a plane in another non-parallel, and thus to achieve complex global shapes in three dimensions.
- the winding process can be judiciously robotized, it allows the removal of fibers while maintaining a tension, which is the guarantor of the straightness of these fibers.
- This local winding can be broken down into a phase of preliminary creation of the node shape by an initial winding around the coil serving to give the resistance and the minimum rigidity to the node, then windings of creation of the consolidated bars by consolidation windings. performed during or after the windings creating bars.
- thermoplastic resin for impregnating the fibers
- the winding is carried out with a heating of the fiber, then a cooling of the whole of the preform to give it an overall cohesion.
- thermosetting fiber impregnating resin the winding is carried out with sufficient heating of the fiber and then cooling of the whole of the preform to give it an overall cohesion with, if necessary, a transition to a crosslinking temperature.
- the preform thus formed is then surrounded by a matrix, preferably but not limited to, of the same material that has been used for impregnating the fibers, or by soaking in a bath of material constituting the matrix, at the temperature recommended to have sufficient fluidity to cover the fiber mesh, either by spraying or by molding in a mold, the filling volume of the piece being injected in addition to the lattice previously arranged in the mold.
- a matrix preferably but not limited to, of the same material that has been used for impregnating the fibers, or by soaking in a bath of material constituting the matrix, at the temperature recommended to have sufficient fluidity to cover the fiber mesh, either by spraying or by molding in a mold, the filling volume of the piece being injected in addition to the lattice previously arranged in the mold.
- FIGS. 1 and 2 are diagrammatic views of a planar rod being manufactured by the method according to the invention
- Figure 3 shows a schematic view of a variant of the same rod.
- FIG. 4 represents a partial schematic view in section of a part of the same connecting rod
- Figures 5, 6, 7 and 8 show schematic perspective views of composite material parts manufactured according to the method.
- planar rod 1 made of composite material manufactured by the implementation of the method according to the invention can be seen.
- Figure 1 shows a first step of manufacturing a lattice structure 10 of reinforcing fibers F, made by filament winding.
- the fiber F which may consist, without limitation, in strands, ribbons or strands of reinforcing fibers, is wound between two pulleys 2 and 3 for constituting the two eyecups of the connecting rod 1, and carried by a not shown frame .
- the chassis also carries coils 4, or intermediate pulleys, disposed between the pulleys 2 and 3, and on which the fiber F is also wound.
- These coils 4, or intermediate pulleys, allow the creation between each pair of coils 4, bars 5 which form the lattice structure 10.
- FIG. 2 shows a next step of the method, which consists in molding on the trellis structure 10, a thermosetting or thermoplastic matrix M according to the case, the coils 4 and the bars 5 being embedded in this matrix M.
- the method according to the invention allows multiple possibilities of realization of the lattice structure 10, especially when the coils 4 have a certain diameter.
- the coils 4 make it possible to vary the coils, direct or crossed, single or multiple so as to allow an optimization of the fiber trellis.
- the molding of the matrix M is carried out in a mold, not shown, and that in it may be arranged, before molding, several preforms each consisting of a lattice structure 10.
- the coils 4 may according to the invention, as is not visible in a plan view, not be in the same plane, so that the bars 5 are inclined in planes not perpendicular to the axes of the coils 4.
- This coil 4 comprises, in this non-limiting embodiment, a shaft 40 and two lateral flanges It will be understood that such a coil 4 allows the fibers F to extend in planes not perpendicular to the axis of the shaft 40.
- the winding of the fiber F at such a coil 4 is decomposed into several phases.
- an initial winding 42 is made around the shaft 40 between the flanges 41, in order to give the resistance and the minimum rigidity to the knot to be formed, then a winding is made to another spool 4 for the creation of the bars. 5, and finally, windings 43 around the shaft 40 and between the fibers F which form the bars 5, and made during and / or after the creation of windings for creating the bars 5.
- windings are intended to block the deformation in compression in the wound area, but also to reduce, as necessary, the length of the bars 5 prone to buckling.
- the winding of the fibers can be made between two coils 4 of non-parallel axes.
- the winding thus obtained is generally twisted while respecting the straightness of the beams 50 of fibers constituting the bars 5.
