Abstract:
1. A method for manufacturing a panel in a composite material using a tooling including a support, comprising: performing a lay-up on the support of the tooling so as to produce a stack of plies of fiber prepregs; consolidating the stack of plies to obtain the panel using a compacting plate arranged above the stack of plies; arranging a first set of polyimide films in contact with the stack of plies, between the stack of plies and the compacting plate, such that adjacent polyimide films partially overlap along adjacent edges thereof forming overlapping zones between the adjacent polyimide films; arranging a second set of polyimide films in contact with the stack of plies, between the stack and the support of the tooling, such that adjacent polyimide films of the second set of polyimide films partially overlap along adjacent edges thereof forming overlapping zones between the adjacent polyimide films of the second set of polyimide films; and creating a vacuum via a plurality of through orifices disposed within the support across the arranged polyimide films, so as to equalize air evacuation through a plurality of the overlapping zones between the adjacent polyimide films, wherein a width of the overlapping zones is approximately 15 mm.
