Patent ID: 8414259

Claim:
A method for manufacturing a turbomachine rectifier comprising an outer ring ( 5 ) and a plurality of stator vanes ( 2 ), said vanes comprising a platform ( 9 ) and a blade ( 12 ), wherein said method comprises at least the following steps: a) first folds ( 7 ) are draped over a core comprising perforations and having the shape of the aerodynamic flow; b) the first folds ( 7 ) are either cut to form incisions ( 8 ) placed opposite the perforations of the core or pre-cut with incisions ( 8 ); c) the blades ( 12 ) of the vanes or, alternatively, the blades ( 12 ) of the vane preforms, are inserted through the incisions ( 8 ) of the first folds ( 7 ) and through the perforations of the core; d) last folds ( 10 ) are draped over the platforms ( 9 ) thus forming a rectifier preform; e) a resin is injected into a closed mold with the preform and the resin-impregnated preform is polymerized; f) a molded piece, essentially having the shape and dimensions of said rectifier, is retrieved from the mold.
