<p>The material contains a support coated on both faces with a film-forming polymer layer and has a felt cloth layer adhering to the polymer film on one face. The material has the form of a flexible cloth consisting of a support A coated on both faces with layers of polymer and/or plastic film-forming material B, and having a felt layer C adhering to a layer of material B on one of its faces. An Independent claim is also included for the process of production of composite material as claimed, by application of a thin layer of B onto each face of a support A, followed by instant application of felt layer C onto one of the layers of B while the latter is still in a paste-like state, and then subjecting the material to treatment causing solidifying and/or gelation of polymeric and/or plastic material.</p> |
