DAMAGE DETECTION TECHNOLOGY FOR COMPOSITE STRUCTURES USING GRID SENSING APPROACH

摘要

Claims [1] A composite structure including a damage diagnosis sensor, comprising: a plurality of first electrodes formed along a first direction on one surface of a composite structure; A plurality of second electrodes formed along a second direction on opposite surfaces of one surface of the composite structure; A first input section for connecting one end of the plurality of first electrodes, and a first output section for connecting the other ends of the plurality of first electrodes; And a second input unit connecting one end of the plurality of second electrodes and a second output unit connecting the other ends of the plurality of second electrodes. When the first electrode and the second electrode are projected on one surface or the opposite surface, they cross each other to form a grating. The first and second electrodes are formed by printing electroconductive ink on the surface of the composite structure using electrohydrodynamic (EHD) inkjet printing.
