The invention relates to a device (100) for compacting and consolidating a stack (110) of fibrous plies preimpregnated with a thermoplastic polymer, which is capable of being placed in an oven, characterized in that it comprises: - spaces (130), referred to as containment spaces, resting on the surface plate (120) and delimiting the perimeter of the stack, said spaces (130) comprising open grooves (131, 132, 133) that open into the perimeter of the stack; - a flexible compacting metal plate (140) having a surface area equal to the surface area of the stack (110) but capable of being inserted inside the perimeter delimited by the containment spaces (130); - means (150, 125) for putting the volume thus enveloped under vacuum comprising a plurality of orifices (125) in the surface plate (120), said plurality consisting of orifices that open outside of the perimeter of the stack. The invention also relates to a process implementing this device for the production of a thick composite panel having a thermoplastic matrix. |
