Abstract
An acoustic attenuation structure comprises a gas permeable composite facesheet, a cellular core, and an impermeable backing. The gas permeable composite facesheet has a designated porosity. The designated porosity causes the permeability of the gas permeable composite facesheet. The gas permeable composite facesheet comprises a carbon fiber fabric. The cellular core is bonded to the gas permeable composite facesheet using a resin of the gas permeable composite facesheet without any additional adhesive. The impermeable backing is connected to the cellular core.
