An experimental study on hole quality and different delamination approaches in the drilling of CARALL, a new FML composite

In this study, the hole quality was investigated in the drilling of CARALL composite. In addition, the delamination factor calculation approaches of Chen, Davim, and Machado were compared in terms of the delamination damage at the hole entrance surface. Chen's approach is based on the conventio...
