The invention discloses a method for testing anisotropic conductivity and interlaminar contact electrical resistivity of a carbon fiber composite material. The method comprises the following steps: preparing carbon fiber prepreg curing plate; selecting a testing electrode; removing influence of temperature and humidity; and acquiring the anisotropic conductivity and the interlaminar contact electrical resistivity. Resistance values in three directions of the single-layered carbon fiber prepreg curing plate are measured by a frequency scanning method on the basis of an impedance measurement principle, electrical resistivity in the three directions of a test piece is solved by a resistance calculating formula, and conductivity tensor of a unidirectional continuous long fiber composite material is deduced on the basis of a coordinate transformation method. According to structural features of a carbon fiber laminate, a current path in the thickness direction is determined on the basis of tunnel effect and capacitive coupling, and a series circuit model in the thickness of the laminate is established. According to the established circuit model, interlaminar contact electrical resistivity of different laminated plates is calculated by the Ohm's law. By the method, systematic analysis and representation to electrical behaviors of the carbon fiber composite materials can be realized.
