Abstract Due to the widespread use of carbon fiber reinforced polymer/plastic
(CFRP), the nondestructive structural health monitoring for CFRP is playing an
increasingly essential role. As a nonradiative, noninvasive and nondestructive
detection technique, planar electrical capacitance tomography (PECT) electrodes
array is employed in this paper to reconstruct the damage image according to the
calculated dielectric constant changes. The shape and duty ratio of PECT electrodes are optimized according to the relations between sensitivity distribution and
the dielectric constant of different anisotropic degrees. The sensitivity matrix of
optimized PECT sensor is more uniform as the result shows, More >
