The lightning strike process is a complex physical phenomenon involving multiple continuous, time-sequenced lightning current components. Due to variations in the electrical characteristics of each component, their damage effects on CFRP composites differ. The combined effect of sequential lightning components, acting continuously without interruption, forms a cumulative process in which each subsequent component acts on the already-damaged material state created by the preceding ones. As a result, the resulting damage differs significantly from that caused by isolated or time-separated components.

摘要

The lightning strike process is a complex physical phenomenon involving multiple continuous, time-sequenced lightning current components. Due to variations in the electrical characteristics of each component, their damage effects on CFRP composites differ. The combined effect of sequential lightning components, acting continuously without interruption, forms a cumulative process in which each subsequent component acts on the already-damaged material state created by the preceding ones. As a result, the resulting damage differs significantly from that caused by isolated or time-separated components.
