Systematic Approach for Finite Element Analysis of Thermoplastic Impregnated 3D Filament Winding Structures—Advancements and Validation

This work aims to enhance and validate a systematic approach for the structural finite element (FE) analysis of thermoplastic impregnated 3D filament winding structures (fiber skeletons). The idealized modeling geometrically complex fiber skeletons used in previous publications is refined by considering additional characteristic dimensions investigating their mechanical influence. Moreover, transferred from meso- macro-level order reduce computational effort. properties FE models are compared using example simple loop specimens. Based on results, respective application fields defined. In next step, same applied more complex, three-dimensional specimen—the inclined loop. For its model, material characterization modeling, as well enhancements geometry, proposed. Together with previously determined effective composite skeletons, these results validated experimental tensile tests
