The tensile failure analysis of the perforated laminates of domestic T700/double horse resin matrix composite laminates was carried out. The effects of different hole diameter and hole shape on the tensile properties of composite laminates were analyzed. The finite element software ABAQUS was used to establish the tensile failure analysis. The failure model was gradually damaged, and the tensile strength of the composite laminates was numerically simulated. The results show that for composite laminates with different hole diameter, the tensile strength decreases significantly with the increase of the diameter of the circular pores. For composite laminates with different hole shape, the tensile strength of laminates with round holes is the largest, and then the elliptical, square and rhombic holes are in turn, the fracture mode of the laminate is the failure of the via. The intensity value obtained by numerical simulation agrees well with the measured strength value, which provides an effective method for strength prediction of porous composite laminates.
