Abstract (en)

[origin: WO2020178500A1] A gas turbine component (10) made of composite material comprises a fibrous reinforcement exhibiting a three-dimensional weave between a plurality of warp threads and a plurality of weft threads, the fibrous reinforcement being densified by a matrix. The densified fibrous reinforcement extends in width between a downstream end and an upstream end in an axial direction and in thickness between an inner surface (11) and an outer surface (12) in a radial direction. The fibrous reinforcement densified by the matrix comprises a recessed portion extending over the entire thickness of the fibrous reinforcement. A filling part made of composite material (50) is present in the free volume of the component defined by the recessed portion, the filling part (50) comprising a fibrous preform exhibiting a three-dimensional weave, the fibrous preform being densified by a matrix.
