  • Patent number: 10239241
    Abstract: A compacting and injection mold for a fiber preform is for use in fabricating a turbine engine guide vane out of composite material. The mold includes a shell forming a trough that is to receive the fiber preform and that is closed in leaktight manner by bottom and top covers, compacting blocks arranged inside the trough each having a surface pressing normally against a surface of the fiber preform that is to be compacted, and closure blocks arranged inside the trough. Each closure block has a surface pressing normally against a surface of a compacting block and does not have a surface in contact with the fiber preform.

  • Patent number: 10040257
    Abstract: The invention relates to a molding device (1) for receiving fibers onto which a resin is injected, including a base (3), side plates (5) confining the base (3), and a cover (7) capable of engaging with a free end (9) of the side plates (5) in order to define an inner space (11) for receiving the fibers and the resin, wherein said device (1) comprises, in the inner space (11), a skin (21) that is configured to be complementary to the inner surface of the cover (7) and to at least a portion of the inner surface of the side plates (5). The invention also relates to a method for manufacturing a resin part using such a device (1).

  • Patent number: 9415549
    Abstract: An impregnation mandrel for production of a gas turbine casing made from composite material, including: a mandrel having a central wall and two side plates; compaction bars, each including (i) a wedge configured to bear against a fibrous reinforcing part covering angles formed between the central wall and the side plates of the mandrel, and (ii) an attachment flange configured to be attached to the corresponding side plate of the mandrel; a flexible casing forming a vacuum bag and configured to be applied at least against the fibrous reinforcing part covering the central wall of the mandrel; and a mechanism for injecting resin into a space defined between the vacuum bag and the mandrel at one of longitudinal ends of the fibrous reinforcement and for extracting the resin at the opposite end.

  • Patent number: 8524026
    Abstract: A former for fabricating a gas composite material casing for a gas turbine, which is obtained by forming fiber reinforcement as superposed layers of a fiber texture and densifying the fiber reinforcement with a matrix, is disclosed. The former has two cheekplates and an annular wall with an outside surface presenting a profile that corresponds to the profile of the inside surface of the casing that is to be fabricated. The annular wall of the former includes a removable fastener device for fastening a fiber texture layer and serving to hold the first layer of the fiber texture mechanically while the fiber texture is being wound on the former.
