Abstract
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.
