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.
Claims7
A process for manufacturing an acoustic panel comprising at least one acoustically resistive layer, at least one cellular structure and a reflective wall, the process comprising successive steps of:
- depositing at least one layer configured in order to form the acoustically resistive layer;
- depositing the cellular structure made of thermosetting composite;
- depositing a film made of thermoplastic resin configured to be miscible with the thermosetting composite at a polymerization temperature of the thermosetting composite;
- polymerizing the thermosetting composite;
- depositing at least one layer made of thermoplastic composite against the film made of thermoplastic resin, the layer being configured to form at least one part of the reflective wall;
- and
- consolidating the layer and the film in order to form the reflective wall.
