Abstract:
A process for manufacturing an acoustic panel including at least one acoustically resistive layer, at least one cellular structure and a reflective wall. The process includes steps of depositing the parts of the acoustic panel made of thermosetting composite, depositing a film made of thermoplastic resin that is miscible with the thermosetting composite at the polymerization temperature of the thermosetting composite, polymerizing the parts of the acoustic panel made of thermosetting composite, and depositing and consolidating at least one layer made of thermoplastic composite against the film made of thermoplastic resin in order to form the reflective wall.
