NONDESTRUCTIVE INSPECTION OF CARBON COMPOSITE STRUCTURES BASED ON MONITORING A POINT CURRENT-SOURCES FIELD
(pp. 46-52)

Abstract. A possibility of nondestructive inspection of the continuity of current-conducting structures using point current sources has been studied. Based on theoretical and experimental studies, electric-current fields in thin-wall elements of structures from electro-conductive material are analyzed. It is shown that the presence of inclusions with less conductivity and continuity disturbances in the material causes distorting the distribution of potential in comparison with field potential in homogeneous element of the structure. The field of potentials is functionally sensitive to characteristics of internal disturbances of continuity that makes it possible to determine quantitative indices of non-continuity characteristics. Advantages and limitations of the proposed testing method in comparison with existing ones are shown. The nondestructive inspection method based on the point current-sources field is suitable for detecting defects similar to continuity dis-turbances and presence of internal inclusions that have an effect on integral conductivity of material in carbon structures (lattice, thin-wall and other structures), even in the case of the one-sided access to a product.It is shown that due to an especial geometric arrangement of sensors (electrodes) on the surface of a product, the method under study allows large-sized structures to be inspected under conditions of the limited two-sided access to the product.The considered method makes it possible to carry out automated nondestructive inspection with automatic determination of a threshold value of a signal for standard-free detection of defects, for example, by cluster analysis methods.

Keywords: nondestructive inspection, current-conducting structures, point current-sources method, carbon composite materials, internal defects, automated inspection.
