Abstract
A device for compacting and consolidating a stack of fibrous plies pre-impregnated with a thermoplastic polymer, configured to be placed in an oven. The device comprises containment blocks, a flexible compacting plate and a vacuum pump. The containment blocks are supported by a board and demarcate the perimeter of the stack. The containment blocks comprise open grooves that open into the perimeter of the stack. The flexible compacting plate has an area equal to that of the stack but is capable of being inserted inside the perimeter demarcated by the containment blocks. The vacuum pump applies a vacuum to the wrapped volume of the stack comprising a plurality of holes in the board that open outside the perimeter of the stack. A method for implementing the device for manufacturing a thick composite panel having a thermoplastic matrix.
