FIELD: molding.
SUBSTANCE: invention relates to a tool for preforming a fibrous preform, a method for preforming a fibrous preform, as well as to a method of producing a turbine part made from a composite material. Tool for preforming a fibrous preform comprises an inflatable first membrane for receiving a fibrous preform, a second membrane, intended for connection to the first membrane by means of fastening system so that to form an inner cavity impermeable for fluid medium between the first and second membranes. Tool comprises a device for vacuumizing the inner cavity between the first membrane and the second membrane.
EFFECT: group of inventions provides simplification and facilitation of formation of a fibrous preform for a part of a complex shape from a composite material in order to optimize injection of a matrix for its compaction.
