Definitions
- the discs To resist these shear forces which generate a delamination effect, the discs must be manufactured so as to minimize structural heterogeneities. Indeed, a non-uniform disc has local stress zones with heterogeneous characteristics which considerably increase the risks of tearing.
- the brake discs are made from a reinforcing textile structure, formed by a plurality of superimposed layers and needled by a set of barbed needles penetrating in the z direction, that is to say transversely to the layers.
- the textile structure is carbonized, densified using a material forming a matrix and is then optionally subjected to a heat treatment.
- the layers are superimposed on a support.
- a step-down movement is generally imposed on the support as the different layers are superimposed and needled.
- the mechanical characteristics of the final product thus obtained strongly depend on the actual needling density chosen for the reinforcing textile structure.
- real needling density is meant a function of the number of needle barbs per cm 3 seen by an elementary volume of the textile structure, which therefore includes the density needling per unit area, the penetration rate in z, the step of downward movement and the functional characteristics of the needles.
- Patent application EP 0 695 823 sought to improve knowledge of the penetration depth of the needles by means of feeler rollers measuring the position of the upper surface of the textile structure between the needling operations and arranged laterally relative to the needle working area.
- the present invention therefore proposes a needling machine and its associated method which overcomes this drawback by allowing a measurement of the real penetration of the needles in the textile structure to be needled taking into account its deformation during the needling operations of the different layers which up.
- these means for measuring the position of the upper surface of said textile structure comprise an optical assembly for contactless measurement.
- it is a wide beam type laser transmitter / receiver.
- these measurement means may include a mechanical contact measurement probe.
- a sensor is provided, preferably of the inductive or optical type, for determining said low point of maximum penetration of the needles and processing means for controlling the vertical movement of said needling table as a function of the measurement of the position. of the upper surface of the textile structure performed at said low point of maximum needle penetration by said measuring means.
- the invention also relates to the process implemented in the aforementioned machine as well as the textile structure obtained by this process.
- the measurement of the position of the upper surface of the textile structure is carried out by means of instantaneous measurements taken in real time over the entire length of the textile structure.
- FIG. 1 is a schematic view of a first embodiment of a machine for needling textile structures according to the invention
- FIG. 2 is a schematic view of a second embodiment of a machine for needling textile structures according to the invention.
- FIG. 3 is a side view of the machine of Figure 2, its right part being shown in a position of maximum insertion of the needles.
- FIGS. 1 and 2 Two embodiments of a machine allowing the needling of a flat textile structure are shown in FIGS. 1 and 2.
- the invention is not limited to the sole manufacture of flat structures and that that of forming a structure by winding a fibrous web also finds application with the present invention, whether it is an annular winding of a web or helical fabric in turns superimposed flat, or a winding of a sheet of turns superimposed on a mandrel.
- the machine conventionally comprises a so-called needling table 10 intended to support layers 12 or plies of width and length determined according to the final structure to be produced, and which will be brought one after the other to be superimposed in successive layers .
- the table is placed directly above a needling head 14 comprising, mounted on a needle board 16, a determined number of barbed needles 18 of known type, and which can be driven in a vertical reciprocating movement by one or more connecting rod-crank assemblies 20 motorized by a single motor or not .
- a stripper 22 fixed to a frame 24 of the machine is mounted above the needling table to prevent the textile structure from being entrained when the needles are raised.
- the table as the stripper are respectively drilled with holes 26, 28 for the passage of needles.
- the table is movable vertically by means of a drive device 30 consisting for example of a motorized worm.
- a drive device 30 consisting for example of a motorized worm.
- Several series of drive rollers 32, 34 (also called input / output presses) arranged upstream and downstream of the machine provide horizontal transport of the textile structure towards the needling head.
- means 36 for measuring the position of an upper surface of the textile structure are provided, disposed at the level of the needling head 14 and intended to determine the actual penetration of the needles into this textile structure, a low point of maximum needle penetration.
- the stroke of the needles being constant relative to the frame to which they are connected and the needling table being positioned at a known distance from this frame, it is easy to show that the distance of penetration of the needles into the material textile directly depends on the thickness of material existing between the needling table and the upper surface measured.
- the measuring means 36 are fixed on the frame 24 and it is provided that the needle board 16 (and the stripper 22) is pierced with an orifice 38 (respectively a passage orifice 40) to allow cooperation of these measuring means with the upper surface of the textile structure.
- this cooperation can be carried out without contact (with a remote measurement of the position of the upper surface of the textile structure) or with contact (by the descent of a mechanical probe on the upper surface of the textile structure).
- FIG. 1 illustrates a preferred embodiment of the invention in which these non-contact measurement means consist of an optical measurement assembly such as a laser transmitter / receiver 42.
- the transmitter directs a laser beam, at through the needle board, towards the upper surface of the textile structure (after having crossed the stripper) which then reflects it towards the receiver. Since the distance from the transmitter to the needling table is assumed to be known by a prior measurement, the determination of the distance from the transmitter to the upper surface of the textile structure, by analyzing the return path of the laser beam, is then sufficient to accurately assess l thickness of the textile structure supported by the needling table.
- this laser assembly is preferably of the wide beam type (because this laser model by allowing measurements over the entire length of the beam ensures an integration effect) .
- this laser model by allowing measurements over the entire length of the beam ensures an integration effect.
- the use of an infrared optical measurement assembly is entirely possible without however being preferred.
- FIG. 2 illustrates an alternative embodiment in which the measuring means consist of a mechanical feeler formed by an internal piston 44 fixed to the frame 24 and on which an external sleeve 46 can slide, the slightly rounded end of which is intended to come into direct contact with the textile structure (after crossing the needle board and the stripper).
- This sliding of the sleeve is ensured by the controlled injection of a fluid, preferably compressed air, into the piston from a control module 48 fixed on the frame 24.
- the pressure of the fluid is adjusted according to the nature of the textile structure to be needled (hardness, rebound reaction) and adjusted so as to avoid any rebound of the sleeve on this textile structure.
- the sleeve also comprises at its upper part a reflective collar 50 intended to cooperate with an optical measurement assembly such as a laser or infrared transmitter / receiver 52 also fixed on the frame.
- the emitter directs its radiation towards the collar of the sleeve which then reflects it towards the receiver.
- the transmitter / receiver distance when the end of the probe is in contact with the needling table, being assumed to be known by a prior measurement, the determination of the transmitter / receiver distance when this end is in contact with the upper surface of the textile structure (by analyzing the return path of the radiated beam) here again suffices to accurately assess the thickness of the textile structure supported by the needling table.
- the measuring means 36 are preferably arranged in a median plane of the needling head 14 perpendicular to a direction of advance of the textile structure (it is of course not prohibited to s '' deviate significantly). They can be split, when this textile structure is in the form of two adjacent plates advancing parallel to one another under the needling head.
- the needling head can comprise two boards with independent needles arranged side by side, the measurement means then being placed substantially in the center of each of these boards.
- this figure 3 shows the machine, in the context of the previous alternative embodiment, in two distinct positions, one (left part of this figure 3) corresponding to a rest position, the head of needling being in the raised position, and the other (right part) corresponding to a position of this head at a low point of maximum needle penetration.
- the determination of the low point of maximum penetration of the needles is carried out in real time by a sensor 54, for example of the inductive or optical type, integral with the frame and cooperating for example with a determined cam profile 56 of the rod-crank assembly 20 control of the vertical reciprocating movement of the needling head.
- This cam profile makes it possible to define a period of time (and not just a single instantaneous measurement instant) during the descent of the needle board, preferably in the vicinity of the low point, during which the measurement means 36 will be active and will be able to acquire several measurements from which will be determined, at the level of a processing module 58 connected on the one hand to the sensor 54 and on the other hand to the measurement means 36, a first average value of the thickness needled layers.
- the needling process implemented in the machine of the invention can be summarized as follows. First of all, superimpose a second layer thickness on a first layer thickness laid on the needling table and bind with barbed needles of a needling head, and according to predetermined conditions, the thicknesses of the two layers thus superimposed, then relatively move the needling table with respect to the needling head by a displacement pitch determined as a function of the position of an upper surface of the two superimposed layers measured at a low point of maximum penetration of the needles by appropriate measurement means, and finally superimpose a third layer thickness on the previous two and link this third layer thickness on the previous two according to the same predetermined conditions. These steps will then be repeated for the following layers until the desired thickness for the textile structure is obtained.
- the method implemented in the machines described above consists in placing on the table 10 first of all one or even two superposed layers which are then linked by needling by means of the needle board 16 while being moved horizontally over the whole length of the textile structure by feed rollers 32, 34.
- the table is then lowered by a determined displacement pitch in order to be able to superimpose a third layer which is in turn needled with the other two and so on until obtain the desired thickness.
- this determined displacement step is not fixed or subject to a predefined law of descent, but it results from the actual penetration of the needles into the preceding layers of the textile structure measured at the low point of maximum penetration of the needles in order to obtain the actual needling density desired for this textile structure, constant or changing density in the thickness of the textile structure.
- the position of the upper surface of this textile structure is measured at the center of the needles to manage the pitch of descent of the needling table, so that these needles penetrate the textile structure from a determined distance.
