Definitions
- the invention relates to a method and a device for compacting and consolidating a thick composite panel with a thermoplastic matrix.
- the invention is more particularly adapted to the manufacture of a thermoplastic panel used for aeronautical applications, particularly for the structure of an aircraft in areas liable to be subjected to impacts, such as the panel, called cap, located at above the cockpit or for the manufacture of highly stressed structural parts, such as the masts supporting the engines, without these application examples being limiting.
- the invention relates both to the manufacture of a flat panel as that of a panel having a curvature.
- Thermoplastic matrix composites more particularly composites with continuous fiber reinforcement in the form of carbon fibers in a matrix of polyetheretherketone or PEEK, are known for their combination of mechanical characteristics, impact resistance and fire behavior.
- the reinforcement rate in the composite is greater than 50% and can reach 65%.
- the term "thick" means panels whose thickness is greater than 20 mm, that is to say more than 150 folds of reinforcement.
- EP-B-2 064 050 discloses a method and a device for producing a thermoplastic matrix composite board having a thickness of between 2 mm and 20 mm.
- the method which is the subject of the invention is a so-called "off-autoclave" process using only the vacuum drawing of the stack of folds in order to obtain the compacting and consolidation thereof.
- the method which is the subject of the invention is particularly advantageous for the manufacture of a large panel whose matrix consists of a polymer with a high melting point such as PEEK.
- the method of the prior art proves poorly suited to the manufacture of a panel intended for a structural aeronautical application and whose finished thickness is greater than 10 mm, that is to say that said panel comprises a stack Moreover 70 folds. Indeed, the risk that a panel of this thickness and obtained by this method of the prior art has a porosity rate incompatible with the intended application is very significant, leading to scrap rates that increase the cost of manufacturing of this panel.
- the invention aims to solve the disadvantages of the prior art and concerns for this purpose a device for compacting and consolidating a stack of fibrous folds pre-impregnated with a thermoplastic polymer, suitable for being placed in an oven, which device comprises:
- shims said containment shims, resting on the marble and defining the perimeter of the stack, said shims having open grooves opening into the perimeter of the stack;
- a flexible compaction plate with a surface equal to the surface of the stack but capable of being inserted inside the perimeter delimited by the containment shims;
- means for evacuating the thus wrapped volume comprising a plurality of orifices in the marble, said plurality consisting of openings opening out of the perimeter of the stack.
- the device that is the subject of the invention makes it possible to obtain optimum compacting of the stack of folds, by directly draining the gases included in this stack by the periphery thereof.
- This characteristic is obtained by the grooved confinement shims which cooperate with the flexible compacting plate to, firstly, control the volume and thickness of the panel during the melting of the polymer constituting the matrix, and secondly, ensure the uniformity of the compaction pressure on the stack of folds.
- Peripheral drainage is obtained by the cooperation of the grooves in the holds and the position of the vacuum draw holes located outside the perimeter of the stack.
- the invention also relates to a method of compacting - consolidating a stack of fibrous plies pre-impregnated with a thermoplastic polymer, using a device according to the invention, which method comprises the steps of:
- the method which is the subject of the invention draws the stack of folds empty during the entire heating process, and more particularly before the melting of the thermoplastic polymer.
- the arrangement of the suction of the device which is the subject of the invention makes it possible to obtain appropriate levels of compaction thanks to effective degassing of the stack.
- the small surface defects of pre-impregnated and non-tacky folds are enough to achieve the degassing of the stack by the peripheral suction by means of grooves made in the wedges of confinement until the fusion of the polymer constituting the matrix.
- Peripheral suction makes it possible to take advantage of this effect for longer than an aspiration carried out essentially through the thickness of the stack as according to the method of the prior art.
- the application of two vacuum levels makes it possible to carry out this degassing up to the melting temperature of the thermoplastic polymer constituting the matrix, then to compact the assembly by the sheet of compaction at the second level of vacuum, while the resin is at a temperature sufficient to impregnate the fibers of the reinforcement. Since this compacting plate does not rest on the wedges and is flexible, it produces a uniform support on the stack by avoiding localized supports that can generate spinning, crease undulations and compacting defects.
- the containment shims are substantially wedge-shaped, the thickness of a wedge between its top and its bearing surface on the marble being degressive from the face of the shim delimiting the perimeter of the stack, forming a inclined pan, which inclined pan is grooved.
- This characteristic substantially improves the degassing of the stack by the periphery and also ensures a uniform pressure in the direction perpendicular to the stack of the vacuum cover on the compacting plate.
- the bearing face of the containment shims on the marble is grooved.
- the peripheral suction is improved in the lower part of the stack, in contact with the marble.
- the face of the containment shims delimiting the perimeter of the stack is grooved.
- the peripheral suction is improved over the entire thickness of the stack.
- the containment shims are made of steel. Thus, they have the rigidity sufficient to contain the volume of the stack during compaction and consolidation thereof.
- the compacting plate is a titanium sheet having a thickness less than or equal to 0.5 mm.
- the resistance of this material is adapted to maintain an elastic behavior at a temperature corresponding to the melting temperature of the polymer constituting the matrix, including for high melting temperatures of the order of 400 ° C., while retaining the flexibility required given the small thickness of the sheet and the elastic modulus of titanium.

- the marble (120) and the containment shims (130) advantageously consist of steel, preferably a so-called tool steel, comprising 0.4% of carbon, 2% of chromium, manganese and molybdenum, a tensile strength greater than or equal to 1000 M Pa.
- the face of the containment shims (130) delimiting the perimeter of the stack (120) is separated from said stack by a drainage fabric (135) consisting of a fabric of fine glass.
- the marble (120) is pierced with a plurality of suction orifices (125) connected by a suitable circuit to a vacuum pump (150).

- the compaction sheet (240), rigid according to the prior art, is supported on the containment shims (230) which are slightly lower than the final thickness of the piece.
- the compacting plate although maintaining the volume, does not apply uniform pressure to said stack (210) thereby producing defects.
- the consolidation takes place at high temperature, for example 400 ° C., the mechanical characteristics of the material constituting the compacting plate fall, so that said sheet (240) also tends to deform but concavely, amplifying thus the phenomenon of local support.
- a drainage fabric (152) for example in the form a coarse glass cloth is placed over the compacting plate, which fabric (152) extends to the surface of the marble (120).
