The development of a lightweight, impact resistant composite insulation foam will enable NASA to inexpensively insulate rocket fuel tanks. Composite foams has particular commercial appeal to the aerospace industry to improve fuel efficiency in time of high fuel price and in the public sector for the maintenance of expensive liquid gases. Target markets include gas products and aerospace companies that utilize liquid gases as fuel. Improved insulation techniques would improve gas storage efficiency that would reduce fuel use and transportation costs. NASA requires cryogenic insulation for spacecraft to improve the efficiency in which missions are completed. Fuel tank insulation is required to (1) function reliably in both ambient and high vacuum environments, (2) be a reusable fill material, (3) be robust, impact resistant, (4) it must not appreciably withhold water, and (5) the materials should be fully breathable to surrounding environment or be completely sealed. The proposed aerogel material would meet all these requirements. In addition, the open cell material is desirable for insulation materials, since any debris that becomes entwined in the pore structure may easily be removed. The structures produced will be designed to meet the structural and thermal requirement set forth by NASA.
