摘要： A method for forming a preform for a hollow turbomachine component is provided. The method includes positioning a sheet made of woven fibers on a base equipped with a longitudinal impression; positioning a mandrel in the longitudinal impression to clamp the sheet between the base and the mandrel, the mandrel having a thickness that increases between a proximal end and a distal end; locking the distal end of the mandrel into position; placing a proximal block resting on the base; forming two flaps of the sheet around the flanks of the mandrel; resting two lateral blocks on the base on either side of the mandrel; locking the lateral blocks into position to form an assembly; drying the assembly to form a preform including a flat base, from which two flaps extend perpendicularly; and adjusting the flaps to the dimensions of the mandrel by trimming excess material.

摘要： A method for manufacturing a thick turbine engine part in a composite material by injection of resin under pressure. A fiber preform is positioned in a mold, a resin composition is injected into the mold, the resin composition is polymerized in the mold so as to obtain the part, and the part is removed from the mold. Prior to the injection of the resin composition, a mold release shim is inserted between the fibrous preform and a wall of the mold, and between the polymerization of the resin composition and the removal of the part from the mold, the mold release shim is extracted.
