Abstract The crack damage forms on the tensile properties of carbon fiber composite laminated plates and the effect
of damage by tensile test of nondestructive, containing loss (the crack damage of different the length ) of carbon fibre
composite laminated plate have been studied. The tensile strength of carbon fiber composite laminates is 517.37MPa, and
the tensile properties of carbon fiber composite laminates are significantly reduced. Compared with the tensile properties
of non-destructive laminates, the tensile strength of laminates with a crack of 5mm was reduced by 26.3% and the tensile
strength of laminates with a crack of 15mm was reduced by 23.4%. Tensile numerical simulation analysis was carried out
on the carbon fibre composite laminated plates based on the three-dimensional progressive damage failure criterion subroutines,
including loss of laminated plates at damage initiation and extension stages. A good agreement was found between
the predicted results and the test data.
