In the process of carbon fiber reinforced plastics (CFRP) drilling

layer is the most important class of defect

which seriously affects the connection performance of the holes and the service life of materials. Rule especially antilayer rule is used for optimization design of laminated composite plate structures. The stacking sequence of composite laminate is optimized by applying Memetic algorithm

and drilling experiment of carbon fiber reinforced plastics is made to check the validity. The result indicates that the stacking sequence has great influence on layer

and the optimized composite laminate can effectively restrain layer and burrs.
