Abstract
A fibrous preform (10) of the component to be manufactured is conformed in the desired shape with the desired degree of compacting, prior to densification by chemical vapor deposition. The conformation is achieved by linking the preform (10) onto a rigid shaping device (12) by threads (30) that traverse the preform (10) and pass through holes (14) in the shaping device. The linking threads (30) are made of carbon or ceramic. Prior to the linking, a covering layer (16) may be arranged on the face of the preform (10) opposite to the one turned towards the shaping device.
