Abstract (en)
[origin: EP1355294A1] The panel, comprising a cellular core (1) with a sounddamping layer (2) on one side and a total reflective layer (3) on the other, has the sound-damping layer made from a structural component (4) of resinbound fibres in contact with and parallel to the aerodynamic flow, a dissipating layer (6) of metallic fabric and a second structural component (7) of resin-bound fibres lying orthogonal to the aerodynamic flow. The two structural components have open surfaces and are made from glass, carbon or polymer fibres, and the metallic fabric is preferably of stainless steel.
