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. A mesh woven form corrosion-resistant metal is bonded to the perforated sheet by additional adhesive between the mesh and the perforated sheet for bonding said mesh to said perforated sheet. The additional adhesive has predetermined characteristics including a minimum viscosity of 1000 poises during curing.
