Abstract
A method for manufacturing a blade made of a composite material for a turbine engine, in particular a turbine engine of an aircraft, wherein a reinforcing shield is attached to one edge of an airfoil, the shield having a generally elongated shape along an elongation axis of the airfoil. The shield includes at least one excess dimension so as to be able to adjust the moment weight of the blade along the axis according to the position of the shield on the edge of the axis, and the method includes a step for removing a surplus portion of the shield so s to balance the blade.

A method for manufacturing a vane made of composite material for a turbine engine comprising the steps of:
- preparing a blade based on fibres embedded in a resin, the blade comprising a suction side and a pressure side extending between a leading edge and a trailing edge,
- attaching a reinforcing shield to an edge of the blade, said shield having an elongate shape along an axis of elongation of the blade,
- wherein the shield attached in the step of attaching the reinforced shield to the edge of the blade comprises at least one excess dimension so as to be able to adjust the moment weight of the vane along said axis according to the position of the shield on the edge along said axis, and in that the method comprises a subsequent step of removing a surplus portion of the shield.
A method of assembling a turbine engine module comprising the steps of:
- manufacturing a plurality of vanes made of composite material, the manufacturing of the vanes comprising:
- preparing blades based on fibres embedded in a resin, each blade comprising a suction side and a pressure side extending between a leading edge and a trailing edge,
- attaching a reinforcing shield to an edge of each blade, said shield having an elongate shape along an axis of elongation of the blade, wherein the shield attached in the step of attaching the reinforced shield to the edge of the blade comprises at least one excess dimension so as to be able to adjust the moment weight of the vane along said axis according to the position of the shield on the edge along said axis,
- removing a surplus portion of the shield,
- the method of assembling further comprising the step of:
- mounting the vanes on a rotor disc.
