This book addresses key challenges in achieving reliable and cost-efficient manufacturing of carbon fibre composite structures. It leverages automated preforming and forming technologies for unidirectional bindered dry-fibre tapes, enabling scalable production of lightweight components for aerospace and automotive applications. The core is the systematic evaluation of Ultrasonic Spot Welding as a rapid, repeatable, and energy-efficient method for tape fixation. Upon analyzing the influence of material characteristics and processing parameters on...
