Abstract: A method for manufacturing an acoustic panel including a first skin, a second skin and an intermediate structure enclosed between these skins and forming oblique cavities with respect to the latter. The method includes an intermediate polymerization step for fastening the intermediate structure to the first skin in order to increase the compressive strength thereof and in particular to support an automated operation of draping the second skin.

Abstract: The disclosure relates in particular to a method of cutting one or more draping elements in a strip of material comprising a fabric layer comprising a film on at least one face. Each draping element is delimited along a determined outline comprising at least one angle, each draping element being cut by means of a cutting blade. At each angle of the outline, the fabric layer and each one film are cut along a curve so as to obtain one or more draping elements without overcutting.
