The present invention relates to a process for manufacturing a panel made of a composite with the aid of tooling having a support (1) on which a lay-up step is carried out, said step consisting in producing a stack (18) of plies of fibre prepregs (20) followed by a step of consolidating the stack with the aim of obtaining the panel by means of a compacting plate (36) placed on top of this stack. According to the invention, the process is implemented in such a way that a first set (26) of polyimide films (28) partly overlapping one another is placed in contact with the stack of plies (18), between said stack and the compacting plate.
La présente invention se rapporte à un procédé de fabrication d'un panneau en matériau composite à l'aide d'un outillage présentant un support (1) sur lequel on effectue une étape de drapage consistant à réaliser un empilement (18) de nappes de fibres pré-imprégnées (20), suivie d'une étape de consolidation de l'empilement visant à obtenir le panneau à l'aide d'une plaque de compactage (36) agencée au-dessus de cet empilement. Selon l'invention, le procédé est mis en oeuvre de sorte qu'un premier ensemble (26) de films polyimides (28) se recouvrant partiellement les uns les autres soit situé au contact de l'empilement de nappes (18), entre ce dernier et la plaque de compactage.
