Abstract Carbon fiber reinforced polymer matrix composites (CFRP) are widely used in various fields because of their excellent properties such as high specific modulus, high specific strength and fatigue resistance. However, due Carbon fiber reinforced polymer matrix composites (CFRP) are widely used in various fields because of their excellent properties such as high specific modulus, high specific strength and fatigue resistance. However, due to its complex use environment, it is easy to cause damage in the process of service and form a safety hazard. For this reason, scholars at home and abroad have studied the mechanical properties of CFRP laminates. The research progress of mechanical properties simulation of CFRP laminates is systematically reviewed from the four perspectives of impact damage, delamination damage, high and low temperature and damp-heat aging and multi-field coupled damage. The research status of CFRP laminate damage mechanism simulation based on advanced numerical analysis methods such as virtual crack closure technology (VCCT), cohesion zone model (CZM) and progressive damage constitutive model (PDM) is described in detail. By comparing different finite element simulation methods, the advantages and existing problems are pointed out, and the future research direction of the mechanical properties simulation of CFRP laminates is prospected. to its complex use environment, it is easy to cause damage in the process of service and form a safety hazard.
