Abstract
A pair of electrodes is connected to a test specimen in order to apply an electric current to the test specimen in the direction of a conductive fiber of each conductive fiber woven fabric of a plurality of prepregs as targets for verification of the presence or absence of waviness, among a plurality of prepregs constituting the test specimen composed of a conductive composite material, and then a magnetic field sensor is relatively scanned over the test specimen, while applying an electric current between the pair of electrodes, to determine a portion of the test specimen where a magnetic field variation is detected by the scanning of the magnetic field sensor as a portion where waviness of the conductive fibers of the conductive fiber woven fabric of the plurality of prepregs as targets for verification of the presence or absence of waviness is present. Thus, it is possible to grasp, for example, the condition of fibers of the conductive composite material in the test specimen as a whole.
