Methods for the utilization of endless fibre reinforced nano-composites for complex structures

子项目6在研究小组2021中位于流程链的末端。研究了纳米颗粒对纤维复合材料结构的影响。除了子项目1-5的研究外，重点不是单纯的材料层面，而是对更复杂结构的研究。重点研究了几何复杂度的增加对无尽纤维增强复合材料工艺性和性能的影响。目的是研究几何上具有挑战性的组件是否存在影响，例如，在简单的优惠券样品中未观察到的改变应力状态或局部不同的纤维压实。作为示例性的结构细节，观察到一个支架和一个更复杂的部件，一个c型框架。特别注意的是注塑行为，损伤容忍度（冲击性能）和部件脱模后的尺寸稳定性。通过将这项实验工作与其他子项目的结果结合起来，将对纳米级颗粒在纤维复合材料结构中的潜力进行全面评估。

Subproject 6 finds its place at the end of the process chain in the research group 2021. The work concentrates on the influence of nano-scaled particles in fiber composites structures. In addition to the research in subproject 1-5 the focus is not on the pure material level but on the investigation of more complex structures. Especially the effects of an increasing geometrical complexity on the manufacturability and properties of endless fiber reinforced composites are investigated. The objective is to study if there are effects in geometrically challenging components, for example by altered stress states or locally different fiber compaction that are not observed in simple coupon samples. As an exemplary structural detail a bracket and as a more complex component a C-frame are observed. Particular attention is laid on the injection behavior, damage tolerance (impact performance) and dimensional stability of the components after demolding. By merging this experimental work with the results from the other subprojects a comprehensive assessment of the potential of nano-scaled particles in fibre composite structures will be performed.
