This proceedings book is based on selected and reviewed contributions from the AUTEX 2025 World Conference, held on June 11–13, 2025, in Dresden, and specifically focuses on structures and composites in textiles. It features research on advanced knitted, woven, and braided structures, hybrid yarns, and high-performance composites for technical, protective, and smart applications. Topics include multiscale and finite element modeling, 3D spacer fabrics, auxetic fiber-reinforced materials, and textile-based sensors for pressure and strain measurement. The volume also addresses ballistic and stabbing resistance of warp interlock textiles, integration of actuators and energy networks into composites, and innovations in moisture management and thermal properties. By combining experimental studies, numerical simulations, and biologically inspired designs, this book provides insights into next-generation textile structures for enhanced functionality and durability.
