The progress of damage during compression-after-impact (CAI) tests of carbon-fibre reinforced plastics (CFRP) laminates made of nanoparticles-coated carbon fibres and subjected to a simulated lightning strike was monitored by acoustic emission (AE). The effects of nanoparticles coating and the degree of damage induced by the simulated lightning strikes on AE activities were examined, with the relationship between the compressive residual strength and AE behaviour being evaluated in terms of AE event counts and the onset of AE activities during the compressive loading. AE monitoring appeared to be useful to assess the degree of impact-damage hence the structural integrity of laminated CFRP structures damaged by lightning strikes.
