Definitions
- the present invention relates to a method for producing a reinforcement for a composite material having a variable resistance profile.
- the invention also covers the reinforcement obtained and the composite product including at least one reinforcement obtained by the implementation of the method.
- This general principle consists in including in a polymer matrix a reinforcement.
- This reinforcement serves to give the composite material the bulk of its mechanical strength.
- These reinforcements are generally fibers of natural material but more generally synthetic and very commonly glass fibers.
- the reinforcements are superimposed and the resistance over the entire length is identical and corresponding at least to the highest resistance required to know the most stressed area of said board. It is possible to have additional layers of reinforcement in the middle of the board in the most stressed area. It is understood that there are several disadvantages to this solution.
- the board obtained does not have optimal characteristics because the transition from the unreinforced area to the reinforced area is not good.
- the method according to the present invention overcomes these problems by proposing the use of continuous fibers in the main direction of stress but with a reinforced resistance in at least one area by a different distribution.
- FIG. 1A a view from above of a simple reinforcement obtained by the method according to the present invention
- FIGS. 1B and 1C two cross-sections of the reinforcement of FIG. 1A respectively along the lines 1B-1B and 1C-1C
- FIGS. 2A and 2B two cross-sectional views of a more complex reinforcement obtained by the same method, following the cut lines identical to those in Figure IA,
- FIGS. 3A and 3B two views of a first pivoting means to enable the process to be carried out in order to obtain a simple reinforcement
- FIGS. 3C and 3B two complementary views of the tops to facilitate the reading of FIGS. 3A
- 3B two views of a first pivoting means to enable the process to be carried out in order to obtain a simple reinforcement
- FIGS. 4A and 4B two views of a second translational embodiment to allow the implementation of the method to obtain a simple reinforcement
- FIGS. 5A and 5B two views of a third embodiment of deployment. to allow the implementation of the method to obtain a simple reinforcement
- - Figure 6 an illustrative schematic view of a snowboard board obtained from the reinforcement obtained according to the method of the invention.
- FIG. 1A a reinforcement 10 is shown composed of a first layer
- the second ply 14 consists of continuous son 16 oriented in the longitudinal direction, in this case indicated by the arrow F.
- the process works continuously and it allows to reproduce modules 18, for example for the realization of a snowboard board.
- Each module comprises three main areas P1, P2 and P3 not including the transition zones T.
- the reinforcing son 16 are continuous, arranged parallel to the longitudinal direction F, and spaced apart from each other.
- next main zone P2 is an area in which the gap of the wires
- a transition zone T is provided since the wires are continuous.
- the arrangement has a total symmetry without it being considered as an obligation.
- zone P2 shown in FIG. 1C, the wires are brought together. It is understood that the figures are schematic and that depending on the products, the son are flattened, especially in case of seams.
- FIGs 1 there is also shown a third layer 20 in the lower part, under the first layer 12 which is a topcoat, for example a veil.
- a topcoat for example a veil.
- the process results in a product which is shown in Figure 6.
- the wires 16 are densified with respect to the narrow and thus reduced surface, which provides a high resistance in this area which is highly mechanically stressed and must have a high rigidity.
- the yarns are spaced apart and the density is lower conferring a lower mechanical strength of this area more weakly solicited but greater flexibility, which is a necessity to confer the board of good qualities.
- the transition zones T can be adapted to be gradual with the desired proportionality.
- the resistance of the assembly is entirely preserved by the continuity of the reinforcement threads. This continuity also makes it possible to transmit the forces and to bind the different front, middle and rear parts. It is also noted that the waste is optimized and that the reinforcing threads are used almost in their entirety. In this embodiment, calculations have shown that there was a saving of 25% of raw material used. The weight of the finished product is also optimized since it was not necessary to densify the reinforcing son 16 in the end zones as in the middle zone.
- the resistance can be improved or modified but this in a known manner by integration of reinforcement threads in the transverse direction, in a regular way, during the manufacture of the first web 12.
- the method is applicable to any product in which it is desirable to modify the mechanical strength of a composite material in a given area, in a given direction.
- the reinforcement 10 obtained by the method according to the invention may also comprise a succession of layers and in FIGS. 2A and 2B, there is shown a superposition of two layers 14 and 14 'of reinforcing threads 16 and 16'. In this case, it is possible to achieve a large number of combinations by intervening diameters, deviations, overlays or not densified zones and all the other parameters already mentioned.
- the manufacture of reinforcements is carried out continuously so that modules such as 18 follow one another.
- FIGS. 3A to 3B A first embodiment is illustrated in FIGS. 3A to 3B.
- This device comprises in a known manner a conveyor 22 on which is positioned a complex consisting of the ply 12 and the ply 20, on which it is appropriate to deposit the ply 14 consisting of the son 16.
- the son 16 from the reels pass through means 24 distribution variable spread.
- These means comprise in the embodiment shown a horizontal guide 26 adapted to take a position transverse to the longitudinal direction F as shown in Figures SA and 3C, in the direction of travel S.
- This guide 26 comprises passages 28 independent one others.
- the number and the gaps between the passages are adapted to the basic differences sought to perform the removal of the son of the web 14 when the guide is perpendicular.
- the guide When the gap must be reduced, as shown in FIGS. 3B and 3D, the guide is oriented to form an incident angle different from 90 °, all the farther from 90 ° that it is desired to reduce the differences between the wires. 16.
- the speed of rotation of the guide for a given forward speed in the direction S conditions the profile of the corresponding transition zone T.
- a disadvantage in certain embodiments that this embodiment poses is that of leading to son deposition offset at the ends of the transition zones. It is therefore possible to tilt the guide to compensate but this can complicate the arrangement.
- FIG. 4A and 4B An alternative shown in Figures 4A and 4B is to use a guide 26-1 which includes spacings with inclined walls, said guide being movable vertically.
- Wire delivery means 16 are associated with said guide.
- the wires are housed in the lower or upper part.
- the relative movement can be obtained either by moving the guide, or by moving the delivery means, or both.
- the guide 26-2 is a support 34 with articulated branches 36 adapted to take different positions causing, as shown in Figures 5A and 5B, different differences depending on whether the branches are spaced apart or constricted.
- the representations are schematic and it is possible to provide other variants and in particular to have the guide pulleys on a support with variable differences by means of cam movements.
