3D terahertz tomography can characterize aging, durability, and flaw conditions in materials for
thermal protection systems and composite overwrap pressure vessels.
NASA has identified the need for
advanced non-destructive evaluation
(NDE) methods to characterize aging
and durability in aircraft materials to
improve the safety of the nation’s airline
fleet. 3D THz tomography can play a
major role in detection and characterization
of flaws and degradation in aircraft
materials, including Kevlar-based composites
and Kevlar and Zylon fabric covers
for soft-shell fan containment where
aging and durability issues are critical.
