Abstract (en)
[origin: WO9426994A1] An acoustic attenuating liner (figs. 6, 7) has a non-metallic honeycomb core (9) bonded on a backsheet (8). At least part of the honeycomb core (9) is at an angle of other than (90) with the backsheet (8). A corrosion-insulated perforated sheet (11) is bonded to the honeycomb core (9) by adhesive (12) between the perforated sheet and the core. A mesh woven (6) from corrosion-resistant metal is bonded to the perforated sheet (11) by additional adhesive (7) between the mesh (6) and the perforated sheet (11) for bonding the mesh (6) to the perforated sheet (11).
