METHODS FOR PRODUCING A PART MADE FROM A COMPOSITE MATERIAL, OBTAINED BY DEPOSITING LAYERS OF REINFORCING FIBERS URGED ONTO A MANDREL

摘要

The invention relates to a method for producing a part made from a composite material, wherein one or more layers (17) of braided or woven or even draped reinforcing fibers (4) are applied to a mandrel having an overall rotationally symmetrical shape. After one or more layers (17) have been applied to the mandrel (2), a compacting operation is carried out either using at least one tie (7), which is helically wound around and along the assembly (6) consisting of the mandrel (2) and each layer (17) of reinforcing fibers (4) that said mandrel supports, or using equipment comprising a frame rotating about the mandrel and bearing an urging member that is applied at least partially radially against the assembly formed by the mandrel (2) and each layer (17, 18) borne thereby.
