AbstractThe objective of SBIR topic N112-102 is to develop a vacuum bagging system compatible with deep draw composite structures to support autoclave and vacuum-bag-only curing processes in a more cost effective manner compared with conventional nylon bagging techniques. The Phase I program efforts focused on the development and demonstration of a single-use liquid polyurethane system that could be applied directly on the composite layup using conventional spray equipment. After rapid curing, the liquid polyurethane system produced an impermeable yet conformal vacuum bag (coating) that is more time and cost effective to apply than conventional vacuum bagging materials, thereby reducing manufacturing costs and improving part quality. The Phase II program will focus on optimizing the performance of the single use system and quickly transitioning this technology to the user environment, while METSS shifts focus to the development of a multi-use spray-on system, which may be more compatible with additional manufacturing scenarios.
