Based on the research of the failure mode and damage mechanism of the notched domestic carbon fiber composite laminates and the experimental analysis

finite element models were established. Then the effect of different failure criterias on the residual strength of notcked domestic carbor fiber composite laminates was studied in the corresponding finite element model. Through the comparison between experimental data and simulation results

it was found that the two-dimensional model could predict the residual strength of the notched domestic carbon fiber composite laminates accurately

the relative error between numerical simulation result and experimental data of failure load was 7.9%

while the relative error of tensile modulus was 5.6%.
