The paper focuses on the problems of potential use of the phased antenna arrays (PAA) in radio-frequency methods for tests and diagnostics of the technical characteristics of such polymer composite materials as aeronautical fibre-glass plastics. Multilayer fibre-glass plastics have a major glue-lime defect between their layers due to their porosity. Such defects might be brought under control with identification of their geometrical location for detecting and remedying technological deficiencies at the stages of manufacturing materials. Phased antenna arrays are applied using ultra-sound for diagnosing connections between metallic materials. Phased methods of researches are more convenient for polymer composite materials, since they open new opportunities for their diagnostics. Furthermore, the use of PAA allows varying the conditions of tests and diagnostics, thus, providing a multivariate test method. The sample of interest shall be tested by radio-frequency pulses within the range of super-high frequencies (from 8.0 to 10.5 GHz), according to the technical specifications for operation. The suggested method enables to automate the process of controlling and diagnosing polymer composite materials, as well as to measure their necessary radio-technical characteristics, required to estimate operation parameters of radio-technical equipment.
