Abstract
An acoustic attenuating liner has a non-metallic honeycomb core bonded on a backsheet. A corrosion-insulated perforated sheet is bonded to the honeycomb core by adhesive between the perforated sheet and the core. The mesh is woven to a plurality of different determined weave patterns from material on and affixed to the perforated sheet, whereby the mesh has a plurality of different resistances. The mesh is aligned with the perforated sheet and is bonded to the perforated sheet by additional adhesive between the mesh and the perforated sheet, thereby providing a segmented liner with a plurality of facesheet resistances.
