Abstract

A composite material turbomachine vane comprising a blade is provided, wherein the vane comprises a first resin reinforced with long fibers and a second resin reinforced with short fibers, the first and second resins being chemically compatible or identical, the long fibers serving to stiffen the vane and the short fibers dispersed in the second resin serving to fill in the parts of the vane that are not reinforced by the long fibers and giving the vane its substantially final shape.
