一种阻尼消音结构的制造方法，由该方法获取的阻尼消音结构及使用该结构的衬垫
摘要：
本发明涉及一种阻尼消音结构的制造方法，该阻尼消音结构能够应用到蜂窝结构上，从而获得一种消音衬垫。所述阻尼消音结构有至少一个多孔层(34)和至少一个加强结构(36)，它们被粘接组合。本发明的特征在于所述方法包括步骤：在所述至少一个加强结构(36)上涂覆无定形粘胶；对加强结构(36)进行穿孔或微型穿孔；以及紧贴着涂覆有无定形粘胶的加强结构(36)的表面放上至少一个所述的多孔层。
摘要（英）：

The invention relates to a method for producing an acoustically resistive structure which can be mounted on a honeycomb structure such as to produce a skin for acoustical treatment, said acoustically resistive structure including at least one porous layer (34) and at least one reinforcing structure (36) which are glued together. The invention is characterised in that the method comprises the following steps in which: an amorphous adhesive is applied to the at least one reinforcing structure (36), the reinforcing structure (36) is subsequently perforated or micro-perforated, and the at least one porous layer is applied against the surface of the reinforcing structure (36) that was coated with amorphous adhesive.
