Abstract
A method of making a metal reinforcing member that is to be mounted on a leading edge or a trailing edge of a composite blade of a turbine engine, the method including: shaping two metal sheets, positioning them on either side of a core including at least one recess that is to form a mold for a spacer for positioning the reinforcing member, assembling them together under a vacuum, conforming them against the core by hot isostatic compression, and cutting them to separate the reinforcing member and release the core.

A method of making a metal reinforcing member for mounting on a leading edge or a trailing edge of a composite blade of a turbine engine, the method comprising:
- shaping two metal sheets to approximate a final shape of the reinforcing member that is to be made;
- positioning the two sheets on either side of a core reproducing inside shapes of a suction side and of a pressure side of the reinforcing member and including at least one recess for forming a mold for a spacer for positioning the reinforcing member relative to the leading edge or the trailing edge of the blade;
- assembling the two sheets together around the core in a leaktight manner and in a vacuum;
- conforming the sheets onto the core by hot isostatic compression;
- and
- cutting the sheets to separate the reinforcing member and release the core.
