Claim Text:
1. A method of fabricating a turbine engine blade or vane out of composite material comprising fiber reinforcement densified by a matrix, the method comprising: performing three-dimensional weaving to make a single-piece fiber blank; shaping the fiber blank to obtain a single-piece fiber preform having a first portion forming a preform for at least a blade or vane airfoil, at least one second portion forming a preform for an inner part of a blade or vane inner platform or for an outer part of a blade or vane outer platform, and at least one third portion forming a preform for an outer part of the blade or vane inner platform or for an inner part of the blade or vane outer platform, wherein said second and third portions of the single-piece fiber preform each cross the first portion of said single-piece fiber preform; and densifying the fiber preform with the matrix in order to obtain the composite material blade or vane having fiber reinforcement constituted by the preform and densified by the matrix, and forming a single piece with at least one of the inner platform and the outer platform incorporated therein.
