Method for manufacturing a part of revolution from composite material with the insertion of an inter-ply anti-stick coating

Abstract

Method for manufacturing a part of revolution in composite material with the insertion of an inter-ply anti-stick coating. The invention relates to a method for manufacturing a part of revolution (100) in composite material for a gas turbine, comprising the following steps: - winding a fibrous texture (140) on several superimposed turns (141, 142, 143, 144) on a mandrel (200) in order to obtain a fibrous preform (300) of a shape of revolution corresponding to that of the part of revolution to be manufactured, said preform extending in width along an axial direction (DA), in thickness along a radial direction (DR) and in length along a circumferential direction (DC), - densification of the fibrous preform (300) by a matrix.During the winding of the fibrous texture (140) onto the mandrel (200), the method further comprises interposing at least one strip of a non-stick material between at least two adjacent turns of the fibrous texture (140), said at least one strip of non-stick material (150) extending in the circumferential direction (DC) along the interface between said at least two adjacent turns, and in that said at least one strip of non-stick material (150) has a width (l150) less than the width of the preform (l140) in the axial direction (DA).
