Vibration Infrared Thermal Method of Defectoscopy of Non-metallic Heterogeneous Materials

Effective using of non-metallic heterogeneous materials and constructions from them requires accurate determination of parameter values characterizing the internal processes that occur in them throughout the entire life cycle. Particular attention should be paid to reliable, operational measurement that could be performed outside the research laboratory. The complexity of the structure, special physical and mechanical properties, the presence of various defects, as well as complex internal processes, which neglecting leads to significant measurement errors and, accordingly, to incorrect decisions regarding their application. That is, classical measurement methods cannot be used to study heterogeneous structures. It is proposed to use the vibrational infrared thermal method of detecting defects of non-metallic heterogeneous materials, which is based on the phenomenon of thermal energy release in their locations under the influence of mechanical vibrations. This method of thermal energy generation has advantages over classical methods, primarily because it does not lead temperature changes in defect-free zones. This increases the accuracy of detecting the location of the defect. In addition, the signal-to-noise ratio increases. A general system designed for flaw detection of non-metallic heterogeneous materials with the help of infrared technology devices with vibrationally excited thermal energy is proposed.
