Summary:
The results of detecting impact damage in woven composites using a 3D microwave imaging system are presented. The microwave results are compared to laser scanner results. After demonstrating the system on two composite samples, the multi-functionality of the system is also discussed. The microwave systems ability to detect changes in permittivity of dielectrics is demonstrated by imaging RTV underneath space shuttle tiles, and the detection of sintered regolith simulant when buried in loose regolith simulant. Multifunctionality makes the system applicable to both Space and Aeronautics applications.
