Definitions
- the invention relates to the production of homogeneous fibrous plies by spreading cables, such plies being used in particular for the manufacture of reinforcements of parts made of composite material.
- spreading cables such plies being used in particular for the manufacture of reinforcements of parts made of composite material.
- To produce relatively large unidirectional fibrous webs it is well known to spread several wires or cables and to juxtapose the spread wires or cables. Spreading can be achieved by passing over curved bars (or "banana” bars) or by passing in front of an air expander.
- Unidirectional plies thus produced can be superimposed with different directions and linked together, for example by needling, to form multidirectional plies. They can also be linked, for example also by needling with other types of fibrous textures, in particular fabrics, to constitute complex fibrous textures which are essentially bidirectional.
- the invention aims to remedy this drawback and proposes for this purpose a method of producing a homogeneous fibrous web by spreading and juxtaposition of wires or cables, method according to which, after at least one pre-spreading of the wires or cables and the bringing of these side by side substantially in the same plane, their surface is swept by at least one air jet displaced transversely relative to the longitudinal direction of the wires or cables, so as to obtain a substantially homogeneous unidirectional sheet.
- the air jet is moved alternately from one edge to the other of the set of wires or cables arranged side by side, while these are moved in the longitudinal direction.
- the air jet is directed substantially perpendicular to the plane of the wires or cables.
- the method according to the invention gives homogeneity to the unidirectional sheet by causing the filaments making up the wires or cables to vibrate by scanning with an air jet. Additional spreading of the wires or cables can be carried out during this scanning.
- At least temporary maintenance of the sheet in the state it is in after air jet sweeping is carried out.
- This support is advantageously obtained by passing over a roller which, at least in its part in contact with the ply, is made of a material having a coefficient of friction such that it opposes a sliding of the filaments liable to result in a tightening of the tablecloth or by discontinuities.
- a material is for example a rubber or a foam.
- the invention also relates to an installation allowing the implementation of the method, installation of the type comprising at least one device for pre-spreading the wires or cables, and means for driving side by side the wires or cables downstream of the device. pre-sprawl.
- the installation further comprises at least one air jet sweeping device disposed on one side of the path of the wires or cables downstream of the pre-spreading device, a supply line for the nozzle. in pressurized air, and a member for driving the nozzle in a transverse direction relative to said path.
- FIG. 2 is a side elevational view on an enlarged scale of the air jet scanning device of the installation of Figure 1;
- FIG. 3 is an elevational view along the plane III-III of Figure 2;
- FIG. 4 is a partial view showing an alternative embodiment of the installation of Figure 1;
- FIG. 5 is a partial view showing another alternative embodiment of the installation of Figure 1.
- each cable 10 drawn from spools 12 is opened and pre-spread by passing over curved bars 14.
- each cable 10 passes over a succession of bars 14a, 14b, 14c by being in contact with the generatrices of the bars, convex side.
- the pre-spread cables 10 are brought side by side on a roller 16 from which they follow a substantially vertical downward path. On this path, the assembly 18 of the cables 10 placed side by side is exposed to an air jet sweep in a transverse direction relative to the direction of movement D of the cables.
- the scanning direction is advantageously perpendicular to the direction D, that is to say, here, substantially horizontal. Furthermore, the scanning direction is substantially parallel to the plane P formed by the set of cables 10.
- the sweep is produced by means of an air ejection nozzle 22 carried by a support 24.
- the latter is fixed to the end of the rod 25 of a jack 26 and is guided in its horizontal displacement by means fixed horizontal rods 28 (shown only in Figures 2 and 3) parallel to the plane 8 and on which the support 24 is engaged.
- a flexible duct 30 supplies pressurized air to the nozzle 22.
- the cylinder 26 is for example a pneumatic cylinder. It is controlled so as to give the nozzle 22 an alternative linear translational movement, from one edge to the other of the assembly 18 of the cables 10.
- Other embodiments of the driving of the nozzle in its alternative horizontal movement may be used.
- the support 22 may be integral with an endless belt passing over a drive roller and a deflection roller at the ends of the stroke of the nozzle 22, the drive roller being coupled to a motor controlled alternately in one way and the other.
- a homogeneous sheet 20 is obtained.
- This passes over at least one roller 32 which, at least in its part in contact with the web, is made of a material having a friction characteristic such that it opposes lateral sliding of the filaments, in order to preserve at the web its width and its homogeneity at least temporarily, until a later fixing.
- This material is for example a rubber or a plastic foam.
- the ply 20 On its path between the roller 16 and the roller 32, the ply 20 is free.
- the tension of the sheet can be defined simply by calling it, downstream of the roller 32, against the weight of the individual coils 12.
- the air jet produced by the nozzle 22 slightly deforms the ply 20 outside of the plane P. This deformation is accompanied by a vibration of the constituent filaments of the cables on the free path of the ply between the rollers 16 and 32, which promotes a substantially homogeneous distribution of these filaments over the width of the ply in combination with the lateral displacement of the nozzle 22.
- FIG. 1 shows pre-spread cables 10 with intervals 11 between cables on the roller 16. The air jet sweep completes the spreading of the cables. he can also make a widening of the ply 20 relative to the total width of the assembly 18.
- the homogenization of the ply 20 by air jet scanning retains its effectiveness even when an effort is made to arrange the cables 10 without intervals between them on the roller 16.
- the passage over the roller 32 contributes to maintaining the filaments of the sheet in their relative positions, therefore to keeping the sheet in its homogeneous distribution.
- the ply 20 can be brought to a topping station 36 supplied with a unidirectional ply 40 which is regularly coated on the ply 20 in continuous movement so that a bidirectional ply 42 is obtained.
- the various constituent layers of the ply 42 can be linked together by light needling in a needling station 44 and the ply obtained can be stored on a take-up roller 46.
- Such an embodiment of multidirectional ply by layering and needling of superimposed unidirectional plies in different directions is well known.
- a pre-spreading or pre-opening of the cables 10, before homogenization and spreading by air jet scanning, may not be necessary, but is most often preferable for separating the filaments of the cables from one another, these which can be more or less mutually bonded by the presence of a size.
- FIG. 4 illustrates an alternative embodiment according to which the pre-spreading of the cables 10 is carried out by passing over a split tube.
- the cables 10 are initially separated into two groups.
- One cable in two passes over a first tube 50, upstream of the roller 16, while the other cables pass over a second tube 52 also upstream of the roller 16.
- Each tube 50, 52 is provided slots 50a, 52a formed through their wall and extending over a limited length parallel to the axis of the tube.
- the slits can be made by laser cutting.
- the tubes 50, 52 are closed at one end and supplied at their other end with pressurized air by means of conduits 54, 56.
- Each cable 10 passes over a slot 50a, 52a, the tubes 50, 52 being oriented perpendicular to the paths of the cables 10.
- the jet of air emitted through each slot causes the cable located opposite to widen. It is possible to pass the cables over a common slotted tube, but the slots, and therefore the pre-spread cables, must be sufficiently spaced so that the air jet for expanding a cable does not disturb the widening of a neighboring cable.
- FIG. 5 illustrates another alternative embodiment according to which the ply 20, after passing between the rollers 32, 34, is superimposed on a fibrous texture 60 fed separately, for example a strip of fabric.
- the complex 62 formed by the sheet 20 and the fabric 60 is wound on a mandrel 64 in order to form an annular cylindrical fibrous preform.
- the fibrous layers superimposed on the mandrel 64 can be bonded together by needling by means of a needle board 66 which extends along a generatrix of the mandrel and which is driven in alternating movement in the radial direction.
- the invention is remarkable in that it allows, by simple and inexpensive means, to obtain a homogeneous sheet from several spread cables.
- the process is preferably carried out with high titer cables.
- homogeneous unidirectional layers of carbon fibers of width varying from 30 to 50 cm have been successfully produced from 48 K carbon cables (48,000 filaments) marketed under the reference “Panex 35-48K” by company of the United States of America "ZOLTEK”.
