Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector
METHOD FOR DEMOULDING A COMPOSITE MATERIAL WITH AN ORGANIC MATRIX
An injection tooling is configured to inject a polymer resin into a fiber preform for fabricating a part in the form of a body of revolution out of composite material, the part having an internal cavity with back-draft. In order to enable the part to be unmolded after the polymer resin has been injected and polymerized, the tooling includes, arranged at least in the internal cavity, firstly a sectorized ring made up of at least three mutually touching inserts including one forming a keystone, the ring having an outside surface that matches the internal cavity with back-draft and an inside surface that presents natural draft, and secondly a conical drum secured to the inside surface of the sectorized ring to support it and that is withdrawn, once separated from the sectorized ring, relying on the natural draft created by the inside surface of the sectorized ring.
