Phase3D Wins Air Force Contract to Inspect Ceramic Matrix Composites in Real Time

Phase3D has won a Department of the Air Force contract to adapt its Fringe Inspection system to ceramic matrix composites, the ultra-hard materials the military wants for hypersonic vehicles, rocket nozzles, and thermal protection tiles. The award puts Phase3D's structured-light scanning technology into one of the most demanding inspection problems in additive manufacturing.

Ceramic matrix composites can survive extreme heat and stress, but they are difficult to make consistently. Defects such as matrix cracking, fiber pull-out, porosity, and delamination can appear at almost every stage of production, from tape fabrication through pyrolysis and final machining. Conventional non-destructive evaluation methods, built mostly for metals and polymer composites, cannot reliably catch these flaws. When a defect is found after the part finishes, the entire piece must be scrapped and rebuilt. That drives up cost and slows delivery for parts the Air Force needs in a hurry.

Fringe Inspection addresses the problem by scanning the build surface during production. The system projects structured light onto the part and generates calibrated height maps that reveal geometry deviations in real time. Phase3D developed the platform for metal additive manufacturing, working with NASA, the Navy, and Air Force sustainment depots. The new contract asks the same question of a completely different material class: is the part you are building actually the part you designed?

The Phase I effort will develop CMC-specific calibration routines and anomaly-classification models. Phase3D will also create validation protocols that let the system identify surface deformation and defect signatures while the part is still on the build plate, rather than waiting for post process CT scanning or destructive sectioning. That shift from inspection after the fact to inspection during printing is the core value proposition, and it mirrors what the company already proved in metal AM.

The immediate end users are the Air Force Life Cycle Management Center's Propulsion Directorate, the Rapid Sustainment Office, and the Air Force Research Laboratory's Materials and Manufacturing Directorate. Phase3D will work with the Oklahoma City Air Logistics Complex and Ellsworth Air Force Base to understand how the system fits into depot and research workflows.

The contract is a meaningful validation for Phase3D. The company has been pushing in situ inspection as a way to move additive manufacturing from prototyping to serial production. Metal AM hit that threshold years ago, but CMCs are still scaling up. If Phase3D can deliver repeatable, real-time quality data for ceramic composites, it will have a unique position in a market where the cost of a late-stage defect is higher than it is in metal.

Ceramic matrix composites are notoriously hard to qualify because so much can go wrong across so many stages. The industry has been trying to solve that with post process CT scans and destructive testing, the same approach that held back metal additive manufacturing in its early days. Real time, layer by layer visibility is exactly what this material needs, and it is exactly what Fringe Inspection already does.
