Title (EN) COMPOSITE MATERIAL FOR PRODUCING AN ACOUSTIC MEMBRANE
(FR) MATÉRIAU COMPOSITE POUR LA PRODUCTION D'UNE MEMBRANE ACOUSTIQUE
Abstract:
(EN) A composite material for producing an acoustic membrane, wherein the composite material comprises a silicone layer comprising an at least partially uncured silicone rubber and a support layer, wherein the support layer is adjacent to the silicone layer,as well as a method of preparing such a composite material and a process for producing an acoustic membrane from such a composite material.
(FR) L'invention porte sur un matériau composite pour produire une membrane acoustique, le matériau composite comprenant une couche de silicone comprenant un caoutchouc de silicone au moins partiellement non durci et une couche de support, la couche de support étant adjacente à la couche de silicone, ainsi que sur un procédé de préparation d'un tel matériau composite et un procédé de production d'une membrane acoustique à partir d'un tel matériau composite.
