Abstract

See full text

A tooling for injecting a polymer resin into a fibrous preform for the manufacture of a revolution part in composite material including a barrel shape with an inside diameter of smaller diameter delimiting the revolution part into an upstream portion and a downstream portion of the inside diameter, the upstream portion including a back-draft intermediate portion, injection tooling wherein, to allow a demolding of the barrel-shaped part once the injection and the polymerization of the polymer resin are carried out, the injection tooling includes on the one hand a frustoconical drum comprising a first drum portion in direct contact with an inner surface of the portion of the revolution part downstream of the inside diameter and a second drum portion and on the other hand a segmented insert whose outer surface matches an inner surface of the portion of the revolution part upstream of the inside diameter.
