A Delamination Factor Prediction Model for Drilling of Composite Materials

In this paper，according to the shell theory , model are developed to predict delamination damage in the drilling process. Finally, we will get theoretical delamination factor and complete the prediction of the delamination damage area. The known references didn’t find similar model of predicting delamination damage. Therefore, it is new method. With the drilling process experimental contrast，the model is more effective for the prediction of delamination of the carbon fiber composite materials.
