Abstract
An acoustically resistive layer comprises at least one layer (,) of acoustic damping cloth and a reinforcing material comprising a sheet (,) of filaments (,) secured to the acoustically damping cloth. The filaments (,) are disposed unidirectionally, bidirectionally or multidirectionally. A process for producing such an acoustically resistive layer, comprises positioning an acoustically damping cloth (,) on a mold (,) having the shape of the layer to be obtained, and disposing on this acoustically damping cloth filaments (,) impregnated with a binder by filamentary winding, and then withdrawing the layer thus obtained from the mold, or by laying with application of pressure, and withdrawing the layer thus obtained from the mold.
