A process for the production of a panel with a protective acoustic damping layer. The protective layer includes at least one porous core covered, on the one side, with a porous acoustic damping layer and on the other side with an acoustic reflector. The porous damping layer is emplaced by striping or draping. The porous damping layer consists of parallel strips. Edges of the strips of the porous damping layer are positioned facing a strip deposited by striping or draping and containing a thermoplastic, thermosetting or thermofusible material adapted, by ...
1. Process for the production of a panel with a protected acoustic damping layer, comprising the steps of:emplacing a porous core between a total acoustic reflector and at least a porous acoustic damping layer;emplacing said porous acoustic damping layer by striping or draping, in order to obtain parallel strips that are distant from adjacent ones of said parallel strips;emplacing only astride intervals between said parallel strips, filaments pre-impregnated with a thermosetting or thermoplastic material; andheating said thermosetting or thermoplastic ma...
