Improving the quality of continuous ultrasonically welded thermoplastic composite joints by adding a consolidator to the welding setup

Continuous ultrasonic welding is a promising high-speed and energy-efficient joining technique for thermoplastic composite structures. However, in the current state-of-the-art research on the topic numerous deconsolidation voids could be identified at the welding interface, which results in a strength knock-down. The aim of this study is,...

Effect of consolidation parameters on (de)consolidation in ultrasonic welding of thermoplastic composites

Thermoplastic composites are gaining prominence in the aerospace industry owing to their higher damage tolerance, cost-efficient means of manufacturing, and the possibility to be recycled. One of the major benefits of thermoplastics compared to thermosets is their ability to be welded, and one of the most promising welding techniques for...
