Polymer Reinforced, Non-Brittle, Light-Weight Cryogenic Insulation for Reduced Life Cycle Costs
Project Description
InnoSense LLC (ISL) proposes to fabricate a composite aerogel foam. This material is designed to be impact resistant, non-brittle, non-water-retaining and insulating for cryogenic propellant storage tanks at a reduced life cycle cost. Since typical liquid rocket fuels consist of liquified hydrogen and oxygen, the proposed material must be able to insulate and maintain cryogenic temperatures. Here, ISL proposes to utilize traditional solvent exchange aerogel protocols to "co-foam" silica and a polymeric additive material. The composite material will maintain the thermal properties of traditional aerogels, and also exhibit an increased flexibility due to the incorporation of a porous polymer additive. The Phase I project will demonstrate that it is feasible to fabricate inexpensive, high performance cryogenic insulation foam through traditional aerogel processing techniques. In addition, this material should exhibit high mechanical performance required for fuel tank applications. Process optimization and field-testing will move forward in Phase II in collaboration with a major NASA prime contractor.

Anticipated Benefits
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. More »
