S. Akhmetkhanov* Mechanical Engineering Research Institute, RAS, 4,M.Kharitonyevskiy Pereulok, 101990 Moscow, Russian Federation Abstract The report presents a method for analyzing images of thermal fields in the form of a thermogram and the results of an experiment on thermal non-destructive testing by an active thermal method of a sample made of a composite material. Local features of the image of thermal fields are investigated by the method of multiple-scale wavelet transform, in which the original image of the thermal field is converted to a number of image components, which allowed to detect defects and heterogeneity of the material structure, that were not determined by the image of the thermal field. The results of the research were verified using the impedance low-frequency acoustic method of flaw detection. 1st International Conference on Integrity and Lifetime in Extreme Environment (ILEE-2019) Non-destructive control of panel from composition material by active heat method R.

Keywords: thermal non-destructive testing, composite materials, defects, heterogeneity of structure, thermal field, thermogram, wavelet analysis, multiple-scale wavelet transform, impedance acoustic method of flaw detection Keyword : th rmal non-destructive testing, compo ite aterials, defects, he erogeneity of structure, thermal field, thermogram, wavelet analysis, multiple-scale wavelet transform, impedance acoustic method of flaw detection Introduction Currently, the method of thermal non-destructive testing (NDT) has become one of the most popular in thermal power, construction and industrial production. The main advantages of thermal control are: versatility, accuracy, efficiency, high performance and the ability to monitor remotely. In thermal methods of non-destructive testing, thermal energy used in the test object is used as trial energy. The temperature field of the surface of the object is a source of information about the features of the heat transfer Introduction Currently, the method of thermal non-destructive testing (NDT) has become one of the most popular in thermal power, construction and industrial production.
