Abstract
A process for the production of a core that can be used for the manufacturing of a part that is made of composite material, whereby the core consists of at least one powdered and/or granular product (16), includes introducing the at least one powdered and/or granular product (16) by vibrating it in an outer envelope (14) placed in a device (18) having a cavity that is delimited by a wall (20) whose geometry is adapted to that of the core to be produced and flattening the outer envelope (14) against the wall (20), characterized in that vibrations are emitted slightly above the fill level during filling.
