METHOD FOR MANUFACTURING A SECTOR OF A TURBINE NOZZLE OR COMPRESSOR STATOR VANE MADE OF A COMPOSITE MATERIAL FOR A TURBINE ENGINE, AND TURBINE OR COMPRESSOR INCLUDING A NOZZLE OR STATOR VANE CONSISTING OF SAID SECTORS

摘要

The invention relates to single-blade vanes, each of which has an inner platform (114), an outer platform (116), and a blade (118), and which are obtained by means of the three-dimensional weaving of an integral fibrous blank, shaping the fibrous blank so as to obtain an integral fibrous preform, and densifying the preform with a matrix so as to obtain a vane made of a composite material forming an integral part with inner and outer platforms. A plurality of vanes are assembled and linked together so as to form a multi-blade sector of a turbine nozzle or compressor stator vane, the linkage being carried out by means of a process including a step of linking by brazing and/or a step of linking by co-densification with a matrix of vanes assembled during an intermediate densification stage.
