Ultrasonic welding of thermoplastic composites with flat energy directors: Influence of the thickness of the energy director on the welding process

This paper presents a detailed experimental examination of the influence of the thickness of flat energy directors (ED) on the ultrasonic welding (USW) process for carbon fibre/polyetherimide composites. Three thicknesses of flat ED were compared: 0.06 mm, 0.25 mm and 0.50 mm. Power and displacement data for 0.06 mm-thick EDs did not clearly...
