摘要：

A novel stitching reinforcement method is applied to the laminates with cut-out for a decrease in the interlaminar stresses. The stitching parameters, such as the distance between edge and stitch line, the thread radius, and the stitch step etc.,are designed,and the three-dimentional models are established for FEM (Finite Element Method). The maximum circumferential shear stress appears in laminates of 0/-45, showing stress distribution similar to analytic solutions. The interlaminar circumferential shear stress of stitched is significantly decreased, and the validity of this method is proved.
