Abstract

The paper presents a complex technology of thermal flaw detection of small-size discontinuity type defects of composite structures. The integrated flaw detection technology is based on the identification of internal defects as sources of heat caused by the use of additional sources of stimulation. The use of complex technology makes it possible to identify types of defects that cannot be detected by the existing methods, for example, defects of small sizes, closed cracks, microcracks, etc. and determine their location in the material. It is shown that the error in determining the depth of defects in the material when using the proposed integrated technology does not exceed 10-15%, which is quite acceptable for practical use.
