Microgravity Fabrication of Freeze-cast Titanium Foams Testing

Completed TRL 5 (started at 5, targeting 5)

Description

The objective of this research includes creating and examining titanium oxide (first two campaigns) and titanium (third campaign) freeze-cast materials (which are not nanoporous, but rather exhibit directionally aligned macropores) in the microgravity environment provided by parabolic flight. This research is a continuation of T0100.
The research was selected for ISS testing in August 2016.

Benefits
Manufacture of structural materials in space poses numerous advantages for space exploration including decreased launch costs and the capability of constructing structures in a space-based environment that are too large for launching. Continued research on this technology will improve a low-cost, scalable technique for the fabrication of titanium foams with desired architectures which will benefit the commercial space industry and future NASA missions. Future Customers Knowledge gained from the research may aid in the development of lightweight materials for the purpose of improved space systems, launch vehicles and payload systems. This will enhance the ability to extend and sustain human activities beyond low-Earth orbit (LEO) by creating a technology which increases the reliability and safety of access to space while also decreasing the overall costs.

How to get involved

This is early/mid-stage (TRL 5) — 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.
