Ambient Processing for In-Situ Selective Reinforcement (ISSR) of Near Net Shape Structures

Use AMPB's laboratory-scale rolling mill to simulate the dynamic conditions associated with metallic structure forming and fabrication methods. Use aerospace aluminum alloys and commercially-available aluminum metal matrix composite (MMC) for reinforcement. Assess aluminum flow behavior and the strain fields within the MMC and their effects on the reinforcing fibers. Flow aluminum plate material into grooved die with preplaced MMC to form and reinforce stiffeners at selected processing temperatures. Evaluate bond microstructures and mechanical properties.

The aeronautics mission directorate is interested in this work and has provided funding for technology maturation.

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.
