Ultrasonic welding of CF/epoxy‐CF/PEI joints with enhanced vibration transfer efficiency and optimized welding quality

This study investigated the impact of welding force on the ultrasonic welding quality of epoxy‐based to polyetherimide (PEI)‐based composite joints. PEI film layers were used on the carbon fiber/epoxy (CF/epoxy) composite surface through a co‐curing process, rendering it “weldable.” The ultrasonic w...
