A method for obtaining a cross-linked fibrous material/silicone elastomer composite and the composite for textile architecture. The method avoids capillary ascension, preserves cohesion of the coated textile, and limits delamination between different silicone layers. The method comprises, in order: 1) coating one face of the textile substrate with a first liquid, silicone composition cross-linkable into an elastomer with a dynamic viscosity before cross-linking of between 5000 and 200000 mPa·s at 25° C.; 2) cross-linking the first liquid silicone composition; 3) coating the other face with a second liquid, silicone composition cross-linkable into an elastomer, said second silicone composition having a dynamic viscosity before cross-linking lower than or equal to 2000 mPa·s at 25° C. for textile core impregnation, and having after cross-linking a number of reactive groups for adhesion of an optional composition subsequently applied onto the second silicone composition; 4) cross-linking the second silicone composition impregnating the textile substrate.
