The invention relates to a method for manufacturing an acoustic panel (20) comprising a first skin (21), a second skin (22) and an intermediate structure (23) enclosed between the skins (21, 22) and forming a cavity (31) inclined relative to the skins. The method is characterized in that it comprises an intermediate polymerization step for fastening the intermediate structure (23) to the first skin (21) in order to increase the compressive strength of the intermediate structure and in particular to support an automated operation covering the second skin (22).
本发明涉及一种用于制造声学面板(20)的方法,所述声学面板包括第一表皮(21)、第二表皮(22)和中间结构(23),中间结构围封在这些表皮(21,22)之间且形成相对于这些表皮倾斜的空腔(31)。该方法的特征在于,该方法包括中间聚合步骤:用于将中间结构(23)紧固到第一表皮(21)上以便增加中间结构的抗压强度且尤其支撑覆盖第二表皮(22)的自动操作。
