On the effect of flat energy directors thickness on heat generation during ultrasonic welding of thermoplastic composites
Composite interfaces (Print)
This paper presents a detailed experimental assessment of the effect of the thickness of flat energy directors (ED) on heat generation at the interface during ultrasonic welding. Power and displacement data showed clear differences caused by the change of thickness, related to heat concentration at the weld line during the process. The extent of the heat-affected zone was assessed by welding specimens without consolidation at different stages of the process. It was confirmed through opticaldoi:10.1080/09276440.2016.1199149 fatcat:2vysxmz7sbfcnjcmdyig2svly4
