Completed TRL 3 (started at 1, targeting 3)
The objective of this research project was to test a new generation of multi-function alumina-silicate based cementitious binders capable of high reflectance, low ablation rate, elevated corrosion resistance, and high mechanical strength. The present work built on previous research undertaken by the research team in the areas of geopolymer binders, high reflectance materials, and computational chemistry of materials behavior in high temperature environments. Full scale and laboratory controlled tests were performed to compare geopolymer performance to commercial products.
The potential impacts of this technology in a rocket engine testing structural setting, was that geopolymers enabled an improved refractory capability in high temperature and high thrust environments where erosion rates are high
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 3) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
