Disclosed is a method for making a membrane for use as a vacuum bag, a natural rubber vacuum bag made using such methods, and methods for using such a natural rubber bag to form a composite article. One method can include providing a substantially non-porous working surface having a desired shape for forming a vacuum bag, spraying at least one layer of a natural rubber liquid over at least a portion of working surface, and solidifying the natural rubber liquid to form a membrane having a shape substantially corresponding to that of the working surface. The membrane formed being elastically deformable and substantially impermeable for functioning as a vacuum bag in Vacuum Assisted Resin Transfer Molding, debulking, compaction, or similar processes.

L'invention concerne un procédé de fabrication d'une membrane destinée à être utilisée en tant que sac sous vide, un sac sous vide en caoutchouc naturel fabriqué en utilisant de tels procédés, et des procédés d'utilisation d'un tel sac en caoutchouc naturel pour former un article composite. Un procédé peut comprendre les étapes consistant à fournir une surface de travail pratiquement non poreuse ayant une forme souhaitée pour former un sac sous vide, pulvériser au moins une couche d'un caoutchouc liquide naturel sur au moins une partie d'une surface de travail, et solidifier le caoutchouc liquide naturel pour former une membrane ayant une forme correspondant sensiblement à celle de la surface de travail. La membrane formée peut se déformer de manière élastique et est pratiquement imperméable pour fonctionner en tant que sac sous vide dans un moulage par transfert de résine par dépression, une réduction de volume, un compactage, ou des procédés similaires.
