Abstract
This study describes the punching behavior of woven carbon fiber reinforced thermoplastic composites. The matrix polymer used is Polyamide 66 (PA66) resin. A circular hole is machined by two types of punch with different tool profiles such as flat edge and wave edge. Load applied at punch which was pushed to laminates with a small servo-pressing unit were measured. The quality of machining was examined by a digital microscope observation of cross-section near hole. It was found that the applied load reduced with increasing the temperature of specimen and working speed of punch. It was also recognized that wave edge tool became lower the applied load than flat edge one.
