摘要： A method of manufacturing a variable-thickness composite-material casing (100) for a gas turbine, comprises: – using three-dimensional or multi-layer weaving to create a fibrous texture (140) in the form of a strip, – winding the fibrous texture (140) in several superposed layers (141, 142, 143, 144) onto a mandrel having a profile corresponding to that of the casing that is to be manufactured, so as to obtain a fibrous preform of a shape corresponding to that of the casing that is to be manufactured, – densifying the fibrous preform using a matrix. During the winding of the fibrous texture (140) onto the mandrel, a textile strip (150) is interposed between the adjacent turns of the fibrous texture, the textile strip (150) having a width smaller than the width of the fibrous texture (140) and delimiting a retention zone of the casing.
