Abstract (en)
[origin: WO2016030613A1] The invention relates to a diffuser vane (2) for a gas turbine engine, comprising a vane assembly (4) made of a composite material having a fibrous reinforcement densified by a matrix, the fibrous reinforcement being obtained from long fibres pre-impregnated and agglomerated in the form of a mat, the vane assembly being provided on at least one leading edge with a reinforcement strip (10-1), said reinforcement strip being made of a single strip of a unidirectional fabric or a textile, or of a stack of a plurality of pre-impregnated plies of a unidirectional fabric or a textile made of carbon fibres or glass fibres, and at least one platform (6, 8) positioned at a radial end of the vane assembly, the platform being made of a composite material having a fibrous reinforcement densified by a matrix, the fibrous reinforcement being obtained from pre-impregnated long fibres. The invention also relates to a method for manufacturing such a vane.
