EXPERIENCE OF USING ACOUSTIC FLAW DETECTORS ID-91M AND AD-60K IN ASSESSING THE QUALITY OF MULTILAYER STRUCTURES
(pp. 57-64)

Abstract. The article considers the experience of using acoustic flaw detectors ID-91M and AD-60K for non-destructive control of the continuity of filling gaps with Vixint-K18 sealant, quality control of composite material based on organoplastics and construction of boroaluminium composite materials. The analysis of publications on the issue under consideration is performed. A list of publications from 15 sources is presented. An analysis of the continuity of filling gaps with a sealant was carried out with the construction of diagrams of the distribution of signal amplitudes across the scanning zones. The measurement results are presented in the figures in the form of a color scheme by selected amplitude scale. The effect on the results of changes in the edge effect is shown, insufficient locality of the sensors used is noted. For structures made of composite materials based on organoplastics and boroaluminum material, dependences of signal amplitudes on the depth of imitators of defects of various sizes are constructed. A static analysis of the measurement results from each of the defect simulators is performed. Good reproducibility of the acoustic signal for specific simulators is shown. The dependences of the signal amplitudes on the layer thickness to the defect simulator are constructed for two different transducers (RSP-60 and SP-60). It is proposed that the SP-60 transducer with less sensitivity but with a monotonic characteristic will be used for a rough estimation of measurement results, and the RSP-60 transducer, with a higher sensitivity but with non-monotonic characteristic, will be used to refine the results. Studies have shown the effectiveness of using acoustic flaw detectors ID-91M and AD-60K with non-destructive testing of the quality of manufacturing a number of structures from multilayer composite materials. Based on the results of the studies, the optimal settings for flaw detectors for various types of controlled parts were selected, a non-destructive testing method for structures by the acoustic method was developed and certified, and metrological parameters of the method were evaluated.

Keywords: nondestructive check, acoustic method, impedance, composite materials.
