STATOR VANE FOR 3D COMPOSITE BLOWER

摘要

The invention relates to a method for manufacturing a stator vane. Said method includes: developing, by 3D weaving into a single part, a fibrous preform (1) including a first portion (10) extending along a longitudinal axis (A) and consisting of the preform of the blade of said vane and, on one longitudinal end (11) of said first portion (10), a second portion (20) forming the preform of the platform of said vane, the second portion (20) being developed into a first layer (40) and a second layer (50) facing the first layer and separated from said first layer (40) by releasing without cutting during the development of said preform (1); folding the first layer (40) and the second layer (50) such that each is in a plane perpendicular to said longitudinal axis substantially symmetrical to each other relative to said first portion (10), and such that a first region (Ri) of the first layer (40) covers a second region (R2) of the second layer (50) in front of a front edge (15) of said first portion (10); shaping said preform (1) in a mold; and densifying said preform (1) with a polymer matrix.
