  • Patent number: 8574388
    Abstract: A method and device for automated manufacture of an elongated composite material part having at least one layer. The method includes depositing, by unrolling onto a mold, in a first direction, along the mold, an assembly having a composite material layer separably attached to a substrate tape, and forming and compacting part of the assembly onto the mold in the first direction. The assembly is partially shaped to the shape of the mold, and then a remaining portion of the assembly is formed and compacted in a second direction, opposite the first direction, to shape the assembly completely to the shape of the mold. Then the assembly is separated, by peeling the substrate tape from the composite material layer that is secured to the mold, by unrolling the substrate tape in the second direction.

  • Patent number: 8382467
    Abstract: A multiple part mandrel on which a hollow body may be formed includes multiple sectors. Each sector has a skin on an outer face and a pair of opposed side returns at longitudinal sides of the sector. The mandrel formed by the sectors is symmetrical about a central axis of the mandrel. When the sectors are assembled as the mandrel, the side returns of adjacent sectors face each other. Each of the side returns includes a recess in an outside surface of the side return, spaced from the skin of the respective sector, and an inflatable O-ring disposed in the recess. The recesses of adjacent side returns in the mandrel are offset with respect to each other in an axial direction of the mandrel. Inflation of the inflatable O-rings urges adjacent sectors together at the skins of the sectors to seal the adjacent sectors at the skins.

  • Publication number: 20100032862
    Abstract: A tool of a composite material for making a cylindrical part of a composite material. The tool is used for forming a mandrel on which the cylindrical part is to be formed. The tool comprises a set of members, each member defining a cylindrical sector of the tool, each member having a bearing structure of a fiber composite and a skin molded on the bearing structure. The tool further includes a seal located at the junctions between the tool members.
