This study presents a finite-element (FE) model considering intralaminar damage and interlaminar delamination to predict the biaxial compression behavior of carbon fiber–reinforced composites (CFRCs) with low-velocity impact damage. First, the FE model was validated by a uniaxial compression experiment. The FE predictions in terms of compression after impact (CAI) strength and failure patterns were consistent with the experimental results. Then the validated FE model was used to predict the biaxial compression behavior of the CFRCs. It was found that the residual strength of the CFRCs was dependent on the buckling mode of the laminate due to the coupling effect of the longitudinal and transverse compressive loadings. Correspondingly, the CAI strength under biaxial compression was lower than that under longitudinal or transverse compressive loading.
