Increase In Accuracy Of Radio Wave Methods Of Diagnostics Of Polymer Composite Materials Defects

Abstract

Issues of the combined radio wave and thermal methods of diagnostics of nondestructive
inspection of the polymer composite materials in the laboratory conditions are considered. The main defect
of the multilayer polymer composite materials is a starved spot between the layers. The paper offers a way
of combining of the processes of measuring and heating the polymer composite materials on the basis of the
radio wave method. As a result, the radiant material heating is obtained, and we judge about the substance
parameters and a presence of defects in the substance by a reflected wave in an indirect method. A
descriptive characteristic of such a problem boils down to describing all the processes in the sample by the
electrodynamic theory. The heating process is described by the electrodynamics equations, but the process
will be described by the thermal equations in the nonstationary heating conditions in the most accurate way
