Abstract
In this paper, a non-destructive and non-contact measurement system for analysis of glass fiber reinforced plastics (GFRP) is presented. The system is based on a frequency modulated continuous wave (FMCW) radar at W-band (75 GHz to 110 GHz). It is demonstrated, that faults like folds or small objects inside the material can be detected. The measurement principle is similar to ultrasonic measurement systems but without the requirement of any coupling medium.
