An acoustic liner has a non-metallic honeycomb core 2 bonded on a backsheet 1. A corrosion-insulated perforated sheet 3 is bonded to the honeycomb core by adhesive 4 between the perforated sheet 3 and the core 2. A mesh 5A, 5B 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 5A, 5B is aligned with the perforated sheet 3 and is bonded to the perforated sheet by additional adhesive 6 between the mesh and the perforated sheet, thereby providing a segmented liner with a plurality of facesheet resistances. This liner avoids the need for splicing common to known liners and thus provides a larger acoustic area and is easier to manufacture. <IMAGE> |
