1. A method for manufacturing a vane for a turbine engine including a root connected to a blade extending according to a longitudinal direction, the method comprising the steps of:
a) providing a root made of a titanium-based alloy, the root being configured to be assembled on a disc;
b) providing a mold comprising a first cavity and a second cavity together defining a recess in which the blade is formed, said recess comprising a first space in which the blade is formed and a second space in which the root is formed,
c) providing aluminum strips including a coating comprising at least one of the hydrophobic and anti-erosion functions and placing them in contact:
with the first cavity in the first space of the recess, and/or
with the second cavity in the first space of the recess;
d) placing a fibrous reinforcement in the first space of the recess and/or in the second space of the recess and at least partially in contact with the aluminum strips;
e) arranging said root in the second space of the recess of said mold; and
f) injecting a compound comprising aluminum into the first space of the recess of the mold so that the compound impregnates the fibrous reinforcement.
