Abstract:
A device for manufacturing a fan casing of a turbomachine made of composite material, in which a mold includes a cylindrical body of lengthways axis and side flanges, and in which a counter-mold includes a cylindrical body and side counter-flanges. The counter-flanges are configured to be attached securely to the flanges, the body of the mold and the body of the counter-mold are concentric, the preform is configured to be positioned between the body of the mold and the body of the counter-mold, and the material of the body of the mold has an appreciably higher expansion coefficient than that of the body of the counter-mold.
