Abstract
WHIPOX™ (Wound highly porous oxide composite) is an innovative alloxide fiber-reinforced ceramic matrix composite for high-temperature applications. We are reporting inspection results generated using fully electronic terahertz sources running at 0.1 THz respectively 0.3 THz in a mobile unit. The system operates in reflection as a frequency modulated continuous wave (FMCW) radar. A comparison of the measured results with investigations using established NDT methods like Xray microCT, lock-in thermography and air coupled ultrasound inspection show the great potential of the new method.
