Distortion simulation and demonstrate of unsymmetrical composite laminates

This paper deals with the simulation of the curing distortion of unsymmetrical composite laminates. The finite element analysis method was used to predict the curing deformations of unsymmetrical 3234/T300 composite laminates with various sizes, ply sequence and thickness. And the unsymmetrical 5224/T300 composite laminates was chose to demonstrate this simulation method. The results indicate that the simulation results of unsymmetrical 3234/T300 composite laminates are in good agreement with the experiments, and the predictions can reflect the effect of parameters on the deformation. The validity of the simulation method was testified by the results of the unsymmetrical 5224/T300 composite laminates.
