Research Institution
CRG proposes a spray-on, reusable advanced vacuum bag system based on cyanate ester elastomer (CEE) material. Current vacuum bag systems do not meet the thermal and chemical needs of today"s high performance aerospace composite needs and/or are difficult to use, resulting in high labor costs and high failure rates. CRG"s CEE material offers inherent thermal and chemical stability, as well as processing characteristics conducive to rapid-cure, spray application. CRG"s Smart Tooling technology is a parallel manufacturing process involving shape memory polymer reinforced with high strain fabric used for layup and cure of complex aerospace epoxy composites. The CEE vacuum bag development will take advantage of formulation expertise, high temperature strain and fatigue characterization, release mechanisms, and commercialization approaches used to advance the technology readiness level and manufacturing readiness level of the Smart Tooling product. CRG is confident in its ability to tailor its existing high-performance CEE materials to fit this manufacturing application.
