Patent ID: 8616853

Claim:
A method of fabricating a guide vane, the method comprising: a) producing a fiber preform by 3D weaving a single piece, the preform comprising a first portion extending along the longitudinal axis and constituting the preform for the airfoil of the vane, and at a longitudinal end of the first portion, a second portion constituting the preform for the platform of the vane, the second portion being produced as a first layer and a second layer facing the first layer and separated from the first layer by unlinking without cutting while producing the preform; b) folding the first and second layers such that each of them lies in a plane perpendicular to the longitudinal axis, substantially symmetrically to each other relative to the first portion, and such that a first region of the first layer covers a second region of the second layer in front of a front edge of the first portion; c) conforming the preform in a mold; and d) densifying the preform with a polymer matrix.
