The invention relates to a method for producing a vulcanizable composite material which can be dynamically stressed. The material is made of an elastomeric matrix having a reinforcement layer made of a textile fabric embedded therein. The fabric is prepared with an aqueous dispersion of synthetic resin and latex before being embedded in the elastomeric matrix and then dried. An adhesive interface coating is applied to the dried fabric with the coating being vulcanizable polar rubber present in an organic solution. The dried fabric provided with the adhesive interface coating is rubberized with a thin coating of rubber stock and embedded in the elastomeric matrix. An organic solution of toluene which contains chlorosulfonated polyethylene (CSM) as a vulcanizable polar rubber is used to apply the adhesive interface coating in order to produce a composite material which provides a good adhesion between the reinforcement layer and the elastomeric matrix even in the presence of high alternating flexural stresses.
