VANE MADE OF COMPOSITE MATERIAL HAVING A THREE-DIMENSIONAL WOVEN FIBROUS REINFORCEMENT AND TWO-DIMENSIONAL WOVEN SKIN AND METHOD FOR MANUFACTURING SAME

摘要

A vane (10) for an aeronautical gas turbine engine comprises, in a longitudinal direction (DL), a blade root (11), a shank (12) and a blade body (13), the blade body extending in the longitudinal direction between the shank (12) and a vane tip (14) and in a transverse direction (DT) between a leading edge (40) made of metal material and a trailing edge (131). The vane comprises a vane core (20) made of composite material having a three-dimensional woven fibrous reinforcement forming the vane root, the shank and a part of the blade body (21). The vane also comprises a skin (30) made of composite material having a two-dimensional woven fibrous reinforcement surrounding the blade body part (21) of the vane core (20), the skin being interposed between the leading edge (40) made of metal material and a front edge of the blade body part of the vane core so as to define a thinned leading-edge portion, the skin comprising one or more two-dimensional woven plies, each wound around the blade body part of the vane core, the skin also defining a thinned trailing edge.
