Abstract
A lightning damage assessment method for the carbon fiber reinforced polymer (CFRP) material considering non-linear impedance characteristic includes steps of: studying various influencing factors of the lightning damage of the CFRP material under the action of the single lightning current component; obtaining the law between the lightning damage of the CFRP material, including the lightning damage area and depth, and various influencing factors, including the peak value, the rising rate, the charge transfer amount, the specific energy of the single lightning current component, and the non-linear impedance characteristic of the CFRP; on the basis of the law, building the multi-factor assessment model of the lightning damage of CFRP material under the action of the single lightning current component; and obtaining mathematical expressions between the lightning damage of the CFRP material and the influencing factors.
