Abstract
Official abstract text for this publication.
A composite vane for a turbine engine, the vane having a pressure side face ( 12 ) and a suction side face ( 14 ) that define the aerodynamic profile of the vane, the vane ( 10 ) comprising: a metallic core ( 20 ) forming the pressure side face ( 12 ) or the suction side face ( 14 ) of the vane; and an organic matrix ( 30 ) associated with the metallic core ( 20 ).
First claim
Opening claim text (preview).
1 . A composite vane for a turbine engine, the vane having a pressure side face and a suction side face that define the aerodynamic profile of the vane, the vane comprising: a metallic core forming the pressure side face or the suction side face of the vane; and an organic matrix associated with the metallic core; Wherein the vane includes at least one platform, the platform being formed by the organic matrix. 2 . A composite vane according to claim 1 , wherein the pressure side and suction side faces extend between a leading edge and a trailing edge of the vane, and wherein the metallic core also forms the leading edge and/or the trailing edge of the vane. 3 . A composite vane according to claim 1 , wherein the organic matrix forms at least part of the suction side face or of the pressure side face of the vane. 4 . A composite vane according to claim 1 , wherein the organic matrix is based on thermoplastic or thermosetting polymer(s). 5 . A fabrication method for fabricating a composite vane according to claim 1 , wherein a resin constituting the organic matrix is injected onto the metallic core, and wherein a vane platform is made by overmolding the platform on the injected assembly including the metallic core by injecting a resin onto said assembly. 6 . A fabrication method for fabricating a composite vane according to claim 1 , including a step of extruding the organic matrix onto the metallic core, and wherein a vane platform is made by overmolding the platform on the extruded assembly including the metallic core by injecting a resin onto said assembly. 7 . A fabrication method according to claim 5 , wherein the resin is injected on the metallic core using an injection-compression technique. 8 . A fabrication method according to claim 5 , wherein the resin includes fillers.
