Abstract
A hybrid polythiourethane elastomer is proposed as a new material for high temperature jet fuel cell bladder inner liners. A commercial source of this type of material is not currently available. This material will combine the durability of polysulfides with the processing flexibility of urethanes. This will allow the development of materials that have curing characteristics that allow flexibility during manufacture and that possess outstanding fuel resistance.During the Phase I effort, a number of candidate fuel cell bladder formulations will be evaluated. The most promising formulation will be presented to the sponsor at the end of the effort. The Phase I work encompasses the development of a durable fuel cell bladder material for use on aircraft. The goal is development of fuel cell bladder products that have good retention of mechanical properties after 200 degree F jet fuel exposure and low volume swell in jet fuel. These products will also meet all environmental regulations for volatile organic compounds emission. A more durable fuel bladder will lead to improved performance and safety on aircraft and will therefore reduce maintenance and replacement costs.
