Improvement of interface anchoring by ultrasonic vibration for adhesively bonded CFRP/Al joints

Adhesively bonded carbon fiber reinforced polymer (CFRP)/Al joints have been widely used in engineering field. However, the bonding strength still needs to be improved. In this study, ultrasonic vibration was applied during the adhesive bonding to promote the micromechanical anchoring at the interface of CFRP/Al joints. Ultrasonic vibration was exerted on the CFRP laminate to transmit the vibration to the adhesive bonding area once the joint was...
