Abstract
The present invention relates to a mandrel for manufacturing a part made from a composite material according to the filament winding technique. The mandrel includes a composite material layer whose threads are wound circumferentially round a metallic casing. The overall thermal expansion of the mandrel according to the invention is close to the expansion of the reinforcing fibers of the parts manufactured on the mandrel. The invention further relates to a use of the mandrel for manufacturing curved elongated profiles.
