Abstract

Abstract. The detection of flaws in polymer materials like degradation areas in polymer pipelines in chemical industry, moisture distributions and delaminations in composites used in aircraft industry are today’s challenges of NDT of polymers. New imaging technologies based on electromagnetic waves at high frequencies from 0.05 to 2 THz are promising candidates for polymer testing in the next future. A variety of terahertz and millimetre-wave systems have been tested to gain an overview on available equipment and their capabilities for different applications in NDT. Image Quality Indicators (IQI’s) of various polymer materials have been developed to evaluate image quality like contrast, signal to noise ratio and spatial resolution as well as edge detection and penetration depth for materials
