FABRICATION PROCESS FOR DISTRIBUTOR SECTOR IN A TURBINE OR COMPRESSOR STATOR VANE OF A COMPOSITE MATERIAL FOR A TURBINE ENGINE AND TURBINE OR A COMPRESSOR INCORPORATING A DISTRIBUTOR OR A STATOR VANE MADE FROM SUCH SECTORS

摘要

Single-blade vanes each having an inner platform (114), an outer platform (116) and a blade (118) are obtained by three-dimensional weaving of a fibrous blank in one piece, shaped of the blank to obtain a fibrous preform in one piece, densification of the preform by a matrix to obtain a blade of composite material forming a single piece with integrated inner and outer platforms. Several blades are assembled and linked together to form a multi-blade sector of turbine distributor or compressor rectifier made of composite material.
