ABSTRACT

Quasi-optical polarization-frequency reflectometry in subterahertz (sub-THz) frequency band is considered as a nondestructive method for detecting of subsurface damage of composite materials. Such materials are used in modern aerospace industry to create robust lightweight structures using adhesive technology. The present paper relates to studying of the possibility of detecting volumetric moisture and thermal damage of the carbon fiber reinforced plastic (CFRP) structures in order to evaluate a quality of surface preparation before CFRP samples bonding. For this purpose we have used quasi-optical beamguide systems to perform polarization in the sub-THz frequency domain (0.1…0.2 ТHz). The measurements of amplitude-frequency and polarization reflecting characteristics of the CFRP samples showed that the thermal effects and volumetric moisture result in changes of reflecting characteristics of samples in this frequency band. The promising results are obtained to use this method when creating means for nondestructive testing and evaluation of the quality of the surface of the CFRP composites before cement together.
