Abstract (en)
[origin: WO2021205132A1] The invention relates to a manufacturing method for a component (12) made from composite material, in particular of a turbomachine (1), the method comprising the following steps: producing a preform (20) with a fibrous reinforcement comprising a first fibrous portion (21) and a second fibrous portion (22), injecting a pressurised matrix into an injection chamber (41) of an injection mould (40), in which the preform (20) is arranged, and polymerising the preform (20). According to the invention, the method comprises a step of positioning a flexible pocket (30) that encloses a fluid and that is arranged between the first fibrous portion (21) and the second fibrous portion (22) before the injection step, the fluid being intended to apply an additional pressure to the preform (20) of the fluid during the polymerisation step.
