The dynamic assembly process of CFRP interference-fit bolted joints under electromagnetic loading was investigated using numerical simulation methods. The impact of interference-fit value on the hole wall was analyzed from both interlaminar and intralaminar damage. The results indicate that no delamination occurs in CFRP laminates at an interference-fit level of 0.5%, while varying degrees of delamination are observed at interference-fit levels of 0.9%, 1.3%, and 1.7%. Additionally, interference-fit levels not exceeding 1.7% do not cause fiber or matrix damage. Furthermore, matrix damage is consistently more extensive and severe than fiber damage under different interference-fit levels, highlighting that the matrix is more susceptible to damage than fibers.
