Abstract
A method for manufacturing a turbine engine vane a root connected to a blade extending in a longitudinal direction includes the steps of providing a root; and providing mold with a first cavity and a second cavity that together define a recess in which the vane is formed. The recess includes a first space in which the blade is formed and a second space in which the root (1), c) is formed. The method further includes the steps of providing aluminum strips; positioning a fibrous reinforcement; arranging the vane root in the second space; and injecting a foam comprising aluminum or injecting an aluminum alloy into the first space of the recess of the mold such that the foam impregnates the fibrous reinforcement.
Claims13
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 vane 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.
