High-Temperature Integral Tank Sealant

There’s a clear need for an AMS 3277 derivative sealant with improved resistance to the higher temperatures (HT) advanced strike aircraft are being designed. To accomplish this SMRC proposes a clay nanoparticle additive to PR-2001 Class B integral fuel tank (IFT) sealant that will: • Improve thermal stability beyond modern strike aircraft requirements • Improve chemical resistance to JP8 • Be compatible with SAE-AMS-C-27725 coatings and adhere to fuel tank materials • Reduce sealant weight by as much as 10% • Increase cost of PR-2001 by less than 10% • Qualify to a temperature enhanced AMS 3277 • Be packaged in a Semkit with the same application and use guidance as PR-2001 • Qualify and test an OEM supply chain, and be ready to manufacture 1 years’ high temperature modified JSF PR-2001 Class B sealant at the end of Phase II. In addition nanoparticle pre-prototype additives will be developed two other aerospace sealants.
