<p>In the present article, the effects of punching process parameters such as punching velocity, type of punching machine, and the shape of punch cutting edge are investigated on the damaged area due to punching process and the residual strength of the punched laminates (determined by three-point bending tests carried out on both punch penetration and punch exit sides). Furthermore, the effect of interleaving electrospun Nylon 6.6 nanofiber mats on the delamination is studied. For this purpose, virgin and nanomodified samples are produced and punched. The size of the damaged area is calculated by means of image processing method. The results show that in both reference and nanomodified laminates, decreasing punching velocity and rounding the cutting edge increase the required punching load and the size of the damaged area. The findings show that, in general, rounding the punch cutting edge highly affects the results compared to other process parameters. However, applying Nylon 6.6 nanofibers compensates for the negative effect of this parameter by controlling the damage in the laminate. The residual strength of the laminate is higher for the cases in which the three-point bending tests are carried out on the punch penetration side. Furthermore, applying Nylon 6.6 nanofibers decreases the size of the damaged area up to 50% and increases the residual strength of the laminate up to 37%, regardless of the variation in punching process parameter.</p>
