Abstract: The invention related to a device for making a part of a composite material by resin-transfer molding, that includes a manufacturing mold in which is placed a blank of the part to be impregnated with resin, characterized in that the manufacturing mold is divided into a matrix and one or more mobile structural member to be indexed on the matrix, the whole defining, after assembly, an imprint corresponding to the shape of the part to be manufactured.

Abstract: A method for manufacturing a part in composite material with a hollow core is provided that includes applying at least one adhesive layer on an open surface of the hollow core. The adhesive layer is a blocking polymerizable adhesive layer having, after polymerization, sealing properties relatively to a resin and capable of preventing its diffusion towards an inside of the hollow core. Subsequently, the blocking adhesive layer is polymerized so as to achieve sealing of the hollow core. Additionally, various parts manufactured according to the methods of the present disclosure are also provided.

Abstract: A device for manufacturing a part in composite material by resin transfer moulding and method is provided according to the present disclosure. The device includes a manufacturing mould in which at least one preform is intended to be arranged of the part intended to be impregnated with resin during a resin transfer process. The mould is subdivided into a die and at least one movable structural element intended to be indexed on the die to form an assembly, the assembly forming a cavity corresponding to a shape of the part to be manufactured. The mould is associated with at least one positioning frame having a low coefficient of thermal expansion in at least one dimension, the positioning frame being designed to allow the indexing and holding in position of the at least one movable structural element, corresponding to at least one singularity, on the die.

Abstract: The invention relates to a device (10) for making a part of a composite material by resin-transfer moulding, that includes a manufacturing mould (10) in which is placed a blank (1) of the part to be impregnated with resin, characterised in that the manufacturing mould (20) is divided into a matrix (21) and one or more mobile structural members (22) to be indexed on the matrix (21), the whole defining, after assembly, an imprint corresponding to the shape of the part to be manufactured.
