Polymer-Reinforced, Non-Brittle, Lightweight Cryogenic Insulation for Reduced Lifecycle Costs

The objective of this project was to develop inexpensive structural cryogenic insulation foam that has increased impact resistance for launch and ground-based cryogenic systems. Two parallel approaches were used: a silica-polymer co-foaming technique and a post-foam coating technique. Structures were fabricated using both techniques to formulate insulation for the specified applications. The insulation will survive in space and terrestrial environments, provide a good moisture barrier, and exhibit thermal insulation properties.
