Ultrasonic welding of lap joints of PEI plates with PEI/CF-fabric prepregs

Vladislav Alexenko, Defang Tian, Sergey Panin, Svetlana Bochkareva, Iliya Panov

In this study, ultrasonic welding (USW) of lap joints of polyetherimide (PEI) plates (adherends) with carbon fiber (CF) prepregs impregnated with PEI was investigated. No energy director (ED) was used, so binder contents were varied in the…
