Abstract
Fiber-reinforced composite materials, with their outstanding direction-dependent properties in combination with Tailored Fiber Placement (TFP) technology, enable the realization of lightweight structures with minimal mass. As part of the project, the TFP technology is combined with the established, efficient, and robust filament winding (FW) technology. This makes it possible to overcome the current manufacturing restrictions of winding (geodesic fiber placement), thereby creating isotensoid composite structures with increased design freedom. The use of variable-axial fiber reinforcements is implemented on an aerodynamically conforming ellipsoidal type V hydrogen pressure tank and a doubly curved engine ring structure of an intermediate casing. For this purpose, requirements arising from the application of the components are derived for the technology. Subsequently, design and dimensioning methods are developed that take into account the multitude of adjustable parameters, the structural requirements, and the technological capabilities of TFP and FW. The TFP technology is further developed for the production of curved patches and tested on the engine ring. The winding technology for non-geodesic fiber placement and integration of TFP patches is redesigned for the layout of space-compliant type V hydrogen pressure tanks. A structure validation accompanying the development process is developed, and the structural proof is carried out exemplarily on both components. The development and validation process takes place in a combined virtual-experimental manner. The development process and the data, shaped by advancing digitalization and increasing complexity, are designed within a collaborative development environment. The results are a functional collaborative research data management system (RDM), a process modeler, workflows for data quality control, and automated data processing functions.
