Process for manufacturing a part made of composite material that comprises at least one radius of curvature

A process for the production of a part made of composite material including at least one radius of curvature, includes a stage for deposition of pre-impregnated fiber layers (24) on a device (22) of convex shape on one another and for compacting the layers, characterized in that localized and repeat...

Zusammenfassung:	A process for the production of a part made of composite material including at least one radius of curvature, includes a stage for deposition of pre-impregnated fiber layers (24) on a device (22) of convex shape on one another and for compacting the layers, characterized in that localized and repeated forces are applied in such a way as to cover the zone of the radius of curvature, at a given instant the forces being applied on a zone that is less than half of the zone of the radius of curvature, so as to compact the fiber layers (24) locally during the deposition stage.
