Composite materials are used for many structures because of its high strong-to-weight ratio and easy formation. Secondary machining processes such as drilling and sawing are required to assemble and join composite materials to other structures. When composite materials are machined, delamination occurs at adhesive layer between laminated layers. Prevention method of delamination at adhesive layer during drilling of composite material using ultrasonic vibration is examined. It is concluded occurrence of delamination is less when ultrasonic vibration is used during drilling. Experimental results are examined by analytical method. Adhesive layer is assumed to be damping component. Condition of occurrence of delamination is demonstrated.
