L'invention concerne un dispositif de stratification et un procédé de stratification permettant de stratifier de manière stable et simple un module à surface incurvée. Le procédé de stratification de la présente invention comprend le positionnement d'un objet de stratification à surface incurvée dans un espace entre un premier et un second diaphragme élastique résistant à la chaleur, et la ventilation de l'espace entre le premier et le second diaphragme tout en appliquant de la chaleur, réalisant ainsi la stratification à une pression appliquée à pression atmosphérique sur le premier et le second diaphragme. Un dispositif de stratification pour ce procédé comprend : des éléments (10, 20) dans lesquels un premier diaphragme (11) et un second diaphragme (21) sont chacun étendus, un premier espace étanche à l'air (14) et un deuxième espace étanche à l'air (24), et un objet de stratification (50) disposé dans un troisième espace scellé (51) entre les diaphragmes ; un moyen de ventilation pour créer un vide dans les espaces étanches à l'air ; et un moyen de chauffage (28) pour chauffer l'objet de stratification.
