DEVELOPMENT OF A YARN GUIDING AND IMPREGNATION TECHNOLOGY FOR ROBOT-ASISSTED FIBER MANUFACTURING OF 3D TEXTILE REINFORCEMENT STRUCTURES

An innovative technological approach will promote a greenhouse-gas-reduced construction method that utilizes the full potential of high-performance textile-reinforced concrete by means of novel and improved construction strategies. To this end, natural load transfer principles, e.g., from botany, are used to achieve maximum material efficiency. The developed highly flexible robotic manufacturing technology is used to realize spatially branched 3D textile reinforcement structures. The paper presents the fiber-gentle and leakage-free yarn guiding and impregnation technology, which is essential for the realization of freely formed 3D textile reinforcements using the robotic 3D yarn deposition technology.
