Method for attaching a metal reinforcement on a leading edge of a turbomachine blade

A method for attaching a metal reinforcement on a leading edge of a composite structure of a turbomachine blade comprising:

• applying adhesive on two opposite surfaces of the leading edge,
• positioning the metal reinforcement on the leading edge, the metal reinforcement comprising two fins each extending along one of the surfaces of the leading edge,
• positioning a first polymer sheet on at least one first face of the blade so as to cover the composite structure of the blade and at least one first fin,
• positioning a pressurising device on the first polymer sheet, the pressurising device being positioned facing the first fin,
• positioning the blade in a vacuum bag,
• placing the vacuum bag under vacuum, such that the pressurising device exerts a pressure on the first fin as a consequence of the pressure exerted by the vacuum bag on the pressurising device, and
• polymerising the adhesive.
