Potential NASA Commercial Applications: The new insulation's ability to maintain its flexibility at cryogenic temperatures makes it a superior choice for cryogenic expansion joints, designed to absorb expansion/contraction stresses. Some examples of cryogenic applications of these new materials include medical storage/transport units, cryogenic fuel tanks, and wind tunnels. The technology developed under this program can benefit aerospace, marine, aircraft, electronic, electrical, rail, automotive, recreation, building materials, and construction industries. Immediate benefit from the proposed Phase I program is the design and fabrication of a composite-based spray deposition insulation system for thermal protection of aircraft surfaces. The ability to tailor the thermal and mechanical properties of proposed thermal coating system allows it to be a flexible solution to meet a wide range of technological needs. The new composite based materials can be used as thermal insulation on marine vessels. They can also be shaped for easy installation as pipe covering. The new materials are specifically suited for the needs of the aircraft industry. These high performance thermal insulators will provide weight savings, improved handling/installation characteristics and enhanced performance durability in service.
