Abstract:

The discovery of new polymeric materials for sealant and seal applications with inherently wider use temperature range, greater chemical stability and longer operational life than state-of-the-art elastomers has proven to be an unyielding challenge to the Air Force for over a decade. Of particular concern has been the need for new viscoelastic polymers with the requisite chemicalfuel resistance, high-temperature stability, low-temperature flexibility, adhesion to metal substrates and ready process ability for improved aircraft integral fuel tank sealants with broad temperature capability. The background, requirements and status of research programs aimed at this specific materials objective, with an emphasis on filleting sealants, was reviewed recently.
