COMPOSITE MATERIAL TURBOMACHINE ENGINE VANE AND METHOD FOR MANUFACTURING SAME

摘要

A turbomachine blade of composite material comprising fiber reinforcement densified by a matrix is fabricated by a method comprising: .cndot. making a one-piece fiber blank (100) by three-dimensional weaving; .cndot. shaping the fiber blank to obtain a one-piece fiber preform having a first portion forming a blade airfoil and root preform and at least one second portion forming a blade platform preform; and .cndot. densifying the preform with a matrix to obtain a composite material blade having fiber reinforcement constituted by the preform and densified by the matrix, forming a single part with at least one incorporated platform.
