Ultrasonic Welding of Novel Carbon/ Elium Thermoplastic Composites with Flat and Integrated Energy Directors: Lap Shear Characterisation and Fractographic Investigation.

The current research work presents a first attempt to investigate the welding attributes of Elium thermoplastic resin and the fusion bonding using ultrafast ultrasonic welding technique. The integrated energy director (ED) polymer-matrix composites (PMCs) panel manufacturing was carried out using the Resin Transfer Moulding (RTM) technique and the scheme is deduced to manufacture a bubble-free panel. Integrated ED configurations and flat specimens with Elium film of different thickness at the interface were investigated for ultrasonic welding optimization.
