Definitions
- the invention relates to the manufacture of composite material parts obtained by application to a mandrel of one or more layers of braided reinforcing fibers.
- a mandrel which is mainly a support on which the braided reinforcing fiber layers are formed.
- the braided layers conform to the outer shape of this mandrel when applied to it, so that the final link has a geometry corresponding to a desired shape.
- the reinforcing fiber layers are applied to the mandrel with a machine-type braiding machine marked 1 in FIG.
- the mandrel 2 is then installed in the machine 1 which essentially comprises a ring 3 carrying two series of coils of reinforcing fibers.
- the reinforcing fibers 4 join on the mandrel which extends along the axis AX, in a convergence region located at a distance from the ring 3, so that the reinforcing fibers jointly delimit a conical shape.
- the initiation of a braiding cycle causes, on the one hand, the displacement of the mandrel 2 with respect to the ring 3 along the axis AX, and on the other hand the displacement along the circumference of the ring of coils of the first series and coils of the second series which turn in opposite directions.
- the coils of the first series follow a first sinusoidal path extending along the circumference of the ring, and the coils of the second series follow a second sinusoidal path also extending along the circumference of the ring. intersecting the first trajectory.
- the coils of the first series and those of the second series are alternated along the circumference of the ring.
- the coils of the first series and the second series turn in direction reverse by following their sinusoidal trajectories, so that they intercross without interfering with each other to form the braid.
- the mandrel advance speed and the rotational speed of the coils are adjusted so that the fibers are braided by being inclined at a predetermined angular value ⁇ such that thirty or sixty degrees with respect to the axis AX.
- Several passages can be made to form several layers of braided fibers superimposed around the mandrel.
- the assembly consisting of the mandrel and the various layers of braided fibers that it carries, is then placed in a mold. Resin is then injected to impregnate the fiber layers, after which this resin is polymerized, for example by heating, so that the assembly consisting of the fiber layers and the resin is a rigid whole.
- This method makes it possible to manufacture a connecting rod having substantially identical mechanical qualities in its different regions. But this method is insufficient to produce competitively connecting rods such as connecting rods 6 and 7 of Figures 2 and 3, for which the desired mechanical properties are different depending on whether one considers their ends or their main body.
- the ends comprise the yokes which constitute the force introduction zones, and they are thus subjected to very different and higher multidirectional mechanical stresses than those of the connecting rod body in which the mechanical stress is mainly longitudinal.
- the object of the invention is to propose a solution to remedy this drawback.
- the subject of the invention is a method for braiding a layer of reinforcing fibers on a mandrel with a braiding machine comprising a ring carrying at least two sets of reinforcing fiber coils:
- the braid forming on the mandrel at a region of convergence of the reinforcing fibers in the vicinity of which these reinforcing fibers jointly delimit a conical shape; characterized in that it comprises
- a step of reconfiguration in which the displacement of the coils is stopped, and in which the machine is rearranged so that the angle at the apex of the cone delimited by the reinforcing fibers in the vicinity of the convergence region takes on a new value, and which the machine is parameterized with a new speed of advance of the mandrel and a new speed of rotation of the coils;
- a braiding recovery step in which the movement of the coils along the ring and the advance of the mandrel are restored with the new speed of advance and the new speed of rotation. Reconfiguring the machine during a braiding operation, by changing the angle of the cone formed by the fibers and the speed of advance of the mandrel and rotation of the coils, allows to produce a braid with different regions corresponding at different inclinations of fibers.
- the braid thus has different mechanical qualities from one region to another, which makes it possible to produce low-cost rods whose mechanical characteristics differ from one region to another.
- the invention also relates to a method as defined above, in which the rearrangement of the machine to modify the angle of the cone delimited by the reinforcing fibers is ensured by bringing the mandrel closer to or away from the ring to increase or decrease the distance separating the ring from the convergence region of the fibers.
- the invention also relates to a method as defined above, in which the rearrangement of the machine to modify the angle of the cone delimited by the reinforcing fibers is ensured by means of an additional ring of diameter smaller than the diameter of the bearing ring. the coils, and bringing this additional ring of the mandrel closer or further apart to increase or decrease the distance separating the additional ring from the fiber convergence region.
- the invention also relates to a method as defined above, wherein the reinforcing fiber coils carried by the ring are rewound when the convergence region is close to the ring.
- the invention also relates to a method as defined above, in which the new angle value of the cone corresponds to the angle value that this cone takes during a stabilized normal braiding cycle in which the mandrel advances with the new speed of advance and in which the coils rotate with the new speed of rotation.
- the invention also relates to a method as defined above, comprising, before rearrangement of the machine so that the angle at the apex of the cone delimited by the reinforcing fibers in the vicinity of the convergence region takes on a new value, the setting place of means enclosing the fibers on the mandrel at the convergence region to maintain them during the rearrangement.
- Figure 1 already described is a schematic overview of a braiding machine
- FIGS. 4A to 4C show schematically in side view a step of reducing the inclination of the fibers according to a first embodiment of the invention
- FIG. 5A to 5C show schematically in side view a step of increasing the inclination of the fibers according to the first embodiment of the invention
- FIGS. 6A to 6C show schematically in side view a step of reducing the inclination of the fibers according to a second embodiment of the invention
- FIG. 7A to 7C show schematically in side view a step of increasing the inclination of the fibers according to the second embodiment of the invention
- FIG. 8 is a side view schematically showing the variations of inclinations of fibers that can be obtained by implementing the method according to the invention.
- the idea underlying the invention is to modify the inclination of the fibers relative to the longitudinal axis during a braiding operation, stopping the machine to reconfigure it by setting a new advance of the mandrel and a new speed of rotation of the coils, but also changing the cone angle formed by the reinforcing fibers in the vicinity of the convergence region of these fibers on the mandrel.
- the angle of the cone formed by the reinforcing fibers is modified by changing the distance separating the mandrel from the ring along the axis AX.
- the angle of the cone formed by the reinforcing fibers is modified by means of a vibrating ring placed inside this cone, and by changing the distance separating this ring from the region. of convergence.
- a mandrel 8 is displaced longitudinally, along an axis AX, in a braiding machine mainly comprising a ring 9 carrying two series of coils of reinforcing fibers, not shown, this ring 9 extending in a normal plane to the AX axis.
- the mandrel 8 is moved along the axis AX according to a first feed speed value Vm1, and the two series of coils are displaced along the ring 9 while turning in direction. reverse around the axis AX at a first speed of rotation oucl predetermined.
- the coils of the first series and the second series are respectively moved by turning in opposite directions, along two sinusoidal paths intersecting along the circumference of the ring, so as to form the braiding of reinforcing fibers.
- the reinforcing fiber braid which is formed on the mandrel 8 is made of fibers which are all inclined relative to the axis AX by a predetermined angle, noted ⁇ 1.
- the rotation of the coils around the axis AX is first stopped, and the mandrel 8 is moved along the axis AX away from the ring 9, so that the fiber convergence region R is separated of the ring by a new distance d2.
- the reinforcing fibers are unwound from the coils in order to allow the mandrel 8 to move away from the ring 9.
- the distance d2 is advantageously determined beforehand, for example empirically or experimentally. It corresponds to the distance at which the ring 9 naturally expands from the convergence region R, when the machine is set so that the braided fibers have a new inclination ⁇ 2 with respect to the axis AX.
- the parameters making it possible to obtain a desired inclination ⁇ 2 ( ⁇ 2 ⁇ 1) are a new value of advance Vm2 and velocity orc2 of the coils determined from the relation given above.
- the machine is parameterized with the new feedrate and the new rotation speed of the coils (Vm2, orc2). It is then activated to cause the advance of the mandrel 8 and the rotation of the coils around the axis AX with these new parameters. This causes the formation of a new portion of braid whose fibers are inclined by the value ⁇ 2 with respect to the axis AX, which is illustrated schematically in Figure 4C.
- the increase of the inclination of the reinforcing fibers with respect to the axis AX is obtained, analogously, by stopping the machine to reconfigure it.
- the rotation of the two series of coils around the axis AX is then stopped, and the mandrel is immobilized along the axis AX.
- the mandrel 8 is then moved along the axis AX, but this time to bring it closer to the ring 9, at the same time as the reinforcing fibers are re-stored on the machine, to allow the approximation of the mandrel 8 without relaxing reinforcing fibers.
- the fibers are re-stored either by rewinding or by any retrofit device of excess length, such a device can be associated with each fiber reel or be a global equipment equipping the machine.
- the mandrel is thus placed in such a way that the fiber convergence region R is spaced from the ring 9 by a new distance d3.
- the new distance d3 has been determined in advance, for example empirically, to correspond to the distance which the convergence region R naturally occupies when the machine is parameterized with values Vm3 and ouc3 corresponding to the new value ⁇ 3 sought for inclination of the fibers with respect to the axis AX.
- the modification of the distance separating the ring 9 from the convergence region R of the fibers makes it possible to modify the angle of the cone C formed by the reinforcing fibers in the vicinity of the convergence region R.
- This angle thus takes the values a1, a2 and a3 when the distance separating the ring 9 from the region R is respectively d1, d2 and d3.
- the angle of this cone C is modified not by varying the distance separating the ring 9 from the convergence region R, but by using a vibrating ring placed at the center of the cone. inside the cone delimited by the reinforcing fibers.
- Such a vibrating ring which is indicated by 1 1 in FIGS. 6A to 7C has a nominal diameter smaller than the internal diameter of the ring 9, and it is placed coaxially with the ring 9 while being spaced from the ring 9 along the AX axis.
- the ring 1 1 is advantageously vibrating so as to reduce the friction of the fibers sliding on it. But this ring can also be chosen non-vibrating in the case where the friction it generates are low.
- the reinforcing fibers delimit a single cone extending from the periphery of the ring 9 and having its vertex at the fiber convergence region R on the mandrel 8
- the ring 9 is brought closer to the convergence region R.
- the ring 11 is placed at a distance e1 from the convergence region R, this distance e1 being such that the angle of the cone C formed by the reinforcing fibers in the vicinity of the convergence region R corresponds to a predetermined value, denoted a1.
- the coils carried by the ring 9 turn on themselves to unwind to allow the displacement of the vibrating ring 1 1 along the axis AX.
- the value a1 of the cone angle has been previously determined, for example empirically. It corresponds to the angle value that naturally takes the cone delimited by the reinforcing fibers when the braiding machine normally operates being parameterized to produce a braid whose fibers are inclined relative to the axis AX of a target value noted ⁇ 1.
- the parameters of the machine for obtaining the inclination ⁇ 1 are the feed speed Vm1 of the mandrel 8 and the speed of rotation orc1 of the coils about the axis AX, which are determined in accordance with the relation given above.
- the braiding cycle is activated, thus causing the formation of a first portion of braid in which the reinforcing fibers are inclined at an angle ⁇ 1 relative to the axis AX, as shown in Figure 6C.
- the decrease in the inclination of the fibers relative to the axis AX in the formed braid is obtained by stopping the machine to reconfigure it.
- the vibrating ring 11 is then moved along the axis AX to be away from the convergence region R, as illustrated schematically in FIG. 7A, so as to reduce the angle of the cone C.
- the 1 1 vibrating ring is simply remote from the convergence region R to be placed at a distance e2 from the convergence region R, which corresponds to a position in which it is no longer in contact with the fibers. But it could be moved to a lower value by staying in contact with the reinforcing fibers.
- the coils carried by the ring can be rewound, so as to maintain these reinforcing fibers sufficiently tight.
- the coils can advantageously be equipped with independent motors for rewinding at each reconfiguration of the machine that requires it.
- the reinforcing fibers constitute a cone whose apex angle has a new value, denoted a2, which corresponds to the value that this cone angle naturally takes when the machine is parameterized to form a braid whose fibers are inclined. relative to the axis AX of a new target angular value, noted ⁇ 2 ( ⁇ 2 ⁇ 1).
- the parameters of the machine for obtaining a target inclination equal to ⁇ 2 are a feed speed of the mandrel Vm2 and a rotational speed orc2 of the coils around the axis AX, determined from the given relation upper.
- the machine is parameterized with the new values of advance Vm2 and speed of rotation ⁇ 2, before being activated, which causes the formation of a new section of braid in which the fibers are inclined with respect to the axis AX of a new value ⁇ 2.
- the machine is stopped to be reconfigured to form a third section in which the inclination of the fibers relative to the axis AX is greater than that of the second section.
- the vibrating ring is then brought closer to the convergence region R, so as to be separated from the latter by a distance denoted e3, such that the angle of the cone formed by the reinforcing fibers in the vicinity of the region R takes a new value noted a3.
- This new value of the angle a3 of the cone C has been previously determined, for example empirically: it corresponds to the angular value taken by the cone C when the machine is parameterized to form a braid whose fibers are inclined with respect to the axis AX of an angular value denoted ⁇ 3 ( ⁇ 3> ⁇ 2).
- the parameters for forming a braid whose fibers are inclined at an angle equal to ⁇ 3 with respect to the axis AX are a new value of the feed speed of the mandrel Vm3 and a new value of speed of rotation orc3 of the coils around the axis AX determined from the relation given above.
- the invention makes it possible to modify the inclination of the fibers over a very short distance, within the same braiding of reinforcing fibers.
- the method according to the invention makes it possible to form the same braid comprising several consecutive segments and corresponding to different inclinations of reinforcing fibers.
- the transition zones from one section to the other are extremely short, even point-like.
- the transition zone has a length virtually zero. It is also possible to modify the angle of the cone C to give it a value significantly different from that corresponding to the new values of advance and rotational speed, which gives rise to a transition zone having a longer length.
- the method according to the invention makes it possible, by locally modifying the inclination of the fibers, to vary the density of fibers along the mandrel, the fiber density increasing with their inclination with respect to the axis AX. It is thus possible to manufacture connecting rods such as those of Figures 2 and 3, increasing the inclination of the fibers in the regions where the cross section of these rods increases.
- the inclination of the fibers is reduced at the level of the connecting rod body, which corresponds to the areas marked B in FIGS. 2 and 3, because the mechanical stress in these regions is on the one hand less, and on the other hand distributed much more uniformly.
- the inclination of the fibers relative to the axis AX at the ends A and C is for example sixty degrees, while it is only thirty degrees for the central regions B corresponding to the rod body.
