摘要:
The present invention relates to a device for manufacturing a part made of a composite by resin injection moulding, comprising a manufacturing mould intended to receive at least one preform, the mould being subdivided into a die and one or more indexed movable structural elements on the die, the assembly forming a cavity corresponding to the shape of the part to manufactured, characterized in that the mould is combined with at least one positioning frame, the expansions of which are stable or controlled in at least one direction, the positioning frame being designed so as to allow the indexation and retention of one or more movable structural elements, corresponding to at least one singularity, on the die.

The present invention relates to a process for manufacturing a part made of a composite having a hollow core (1) comprising the following steps: - applying at least one adhesive layer (6) to an open surface of the hollow core, said process being characterized in that the adhesive layer is a polymerizable blocking adhesive layer having, after polymerization, sealing properties with respect to a resin, and capable of preventing the diffusion of a resin into the hollow core; - and polymerizing the blocking adhesive layer so as to seal the hollow core.
