Applying Ultrasonic Vibration to Decrease Drilling-Induced Delamination in GFRP Laminates

Delamination is a major problem in drilling of fiber-reinforced composite materials. Thrust force is an important factor leading to propagation of delamination during drilling process. One of effective methods to reduce machining forces is application of ultrasonic vibrations. In this study ultrason...
