要約(英語): The transient distribution of lightning current in a 3-mm-thick multilayer carbon-fiber-reinforced plastic (CFRP) panel is studied using the finite-difference time-domain (FDTD) method. The transient distributions of electric field on the sides of the panel are also analyzed since high-intensity electric field there might cause electrical sparks. The 3-mm-thick CFRP panel is composed of 0.2-mm-thick layers. Each 0.2-mm-thick layer has a fiber direction of 45°, 90°, -45° or 0°. Therefore, it has an anisotropic conductivity: the conductivity is high in the fiber axial direction and low in other directions. It is quite difficult to represent such an anisotropic layered panel using the FDTD method with common rectangular-prism or cubic cells. In this paper, thin triangular-prism cells are employed in the FDTD simulation to represent the anisotropic layered structure of CFRP panel. The computations are performed with a super computer, which allows us to represent the realistic 3-mm-thick CFRP panel composed of 0.2-mm-thick layers.
