Abstract

Presents studies aimed at creating a methodology for assessing the depth of defects in multilayer honeycomb parts made of polymer composite materials during impedance testing with serial flaw detectors with the construction of C-scans. There are methods for estimating depth based on data with two independent parameters, which require special equipment and software. The study is aimed at creating a technique based on the analysis of only one parameter due to the knowledge of the mechanisms of the influence of the depth of defects on the impedance value and understanding the nature of the change in the signal of the flaw detector when the load changes.
