Carbon fiber reinforced polymer composites inevitably require drilling for mechanical connections during assembly processes in the aviation industry, yet the presence of holes in structural components adversely affects their mechanical properties. The study investigated the failure behavior of T300 and QY8911 carbon fiber composite open-hole laminates under tensile loading through combined experimental and numerical approaches. Open-hole laminate specimens featuring three typical stacking sequences were fabricated and subjected to tensile testing. A representative volume element (RVE) model was established from the mesoscopic perspective, and the macroscopic elastic properties of composite were characterized across scales based on progressive homogenization theory. Concurrently, an extended finite element method (XFEM) model coupled with the LaRC05 failure criterion via the UDMGINI subroutine was developed to establish a damage model accounting for multiple failure modes including fiber fracture and slippage as well as matrix cracking, thereby enabling crack propagation simulation. The results indicated that the numerical predictions agreed well with experimental data. Dominant failure mechanism of composite open-hole laminates with different stacking sequences transitioned from fiber-dominated damage to matrix-dominated damage, and crack trajectories exhibited strong correlation with ply orientations. The findings validated the effectiveness of proposed extended finite element model in predicting damage behavior of open-hole CFRP laminates, providing a reliable methodology for composite structural design and strength assessment.
