This study examines the evolution of damage in graphite/epoxy composite laminates due to lightning strikes. To clarify the influence of lightning parameters and specimen size, artificial lightning testing was performed on a series of laminated composite specimens. Damage was assessed using visual inspection, ultrasonic testing, micro X-ray inspection, and sectional observation. The results showed that the damage modes can be categorized into fiber damage, resin deterioration, and internal delamination modes. Damage progression is governed by the strong electrical orthotropic properties of the laminates, and the lightning parameters defining impulse waveform show strong relationship with certain damage modes, though specimen size and thickness variation barely affect damage size.
