Abstract
When an alternating current is applied to a conductive slab, the induced current impedes the electric current and causes a skin effect. This effect is found in all conductive materials. For laminated carbon fiber reinforced plastics (CFRP), however, the depth of the skin effect has not previously been evaluated. In the present study, therefore, we analytically solve Maxwell’s equations to derive the skin effect depth of unidirectional CFRP. Using this result, the skin effect is analyzed for laminated CFRP, and its depth is then derived. The effect is then compared with a newly defined skin effect of anisotropic conductance. For highly toughened CFRP that have resin rich layers, the skin effect of anisotropic conductance is found to be more important than that of the alternating current.
