Abstract (en)
[origin: WO2011070279A1] Process for manufacturing an acoustic panel for an aircraft nacelle. The invention relates to a process for manufacturing an acoustic panel (1) for a nacelle of an aircraft, said panel (1) comprising a metallic acoustic absorption structure (7) and an acoustic skin (3) having a multitude of acoustic openings (5), said process comprising: - a step A in which a layer (21) is formed that contains a polymerizable insulating material around the acoustic openings (5) of the acoustic skin (3), said insulating material being configured to protect the acoustic absorption structure (7) from corrosion; - a step B in which the layer (21) thus obtained is solidified by polymerization.
