Abstract
A method of fabricating a composite material casing of varying thickness for a gas turbine includes using three-dimensional or multilayer weaving to make a fiber texture in the form of a strip; winding the fiber texture as a plurality of superposed layers onto a mandrel of profile corresponding to the profile of the casing to be fabricated, so as to obtain a fiber preform of shape corresponding to the shape of the casing to be fabricated; and densifying the fiber preform with a matrix. During winding of the fiber texture on the mandrel, a textile strip is interposed between the adjacent turns of the fiber texture, the textile strip presenting a width that is less than the width of the fiber texture and defining a retention zone of the casing.
