Cyanate Ester Elastomer Reusable Vacuum Bag Navy SBIR FY2011.2 Sol No.: Navy SBIR FY2011.2 Topic No.: N112-102 Topic Title: Cyanate Ester Elastomer Reusable Vacuum Bag Proposal No.: N112-102-0597 Firm: Cornerstone Research Group, Inc. 2750 Indian Ripple Road Dayton, Ohio 45440-3638 Contact: Thomas Barnell Phone: (937) 320-1877 Web Site: www.CRGrp.com Abstract: 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. Benefits: Operational Benefits: (1) Increased composite fabrication efficiency and quality (2) Higher thermal and chemical resistance (3) Increased robustness and longer lifetime Commercial Applications: (1) Aerospace composite parts (2) Marine composite applications (3) Sports and recreation composites Return
