Abstract
A method for closing an injection mold for manufacturing a revolution part made of composite material, the mold including a mandrel supporting a fiber preform and angular sectors comprising an annular base to come into contact with the fiber texture, the annular base extending between first and second side edges along a circumferential direction. The method includes successive positioning and fixing the angular sectors on the mandrel, the annular base of each sector compacting the fiber preform portion present oppositely, the side edges of the annular base of each angular sector being in contact with the side edges of the annular base of the adjacent sectors. Before the positioning and fixing of the angular sectors on the mandrel, strip s are placed on the exposed surface of the fiber preform, each strip covering an area of the fiber preform located facing a junction area between two adjacent angular sectors.
