Abstract:
1. A reusable vacuum bag configured for application of at least one sealant bead, the sealant bead providing vacuum tight sealing of the reusable vacuum bag to a forming tool during fabrication of a composite part on the forming tool, the reusable vacuum bag comprising: at least one elastomeric layer having polymers, the elastomeric layer being sealable to the forming tool and having a sealing flange extending peripherally thereabout; and a fluoroelastomeric strip having polymers and extending substantially along the sealing flange and having first and second surfaces, the polymers of the elastomeric layer cross-linking with the polymers of the fluoroelastomeric strip at an elevated temperature such that a permanent bond is formed between the sealing flange and the fluoroelastomeric strip at the first surface, the fluoroelastomeric strip being releaseably adhered at the second surface to the sealant bead.
