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.

子项目6在2021年研究组的过程链末端找到了自己的位置。本文主要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中的研究外，重点不是纯粹的材料层面，而是更复杂的结构的研究。特别研究了几何复杂性的增加对环形纤维增强复合材料的可制造性和性能的影响。我们的目标是研究在几何挑战成分中是否存在影响，例如，改变应力状态或局部不同的纤维压实，这在简单的试片样本中没有观察到。作为一个示例性的结构细节，观察到了支架和作为更复杂的部件的C型框架。重点研究了拆卸后构件的注塑行为、损伤容限(冲击性能)和尺寸稳定性。通过将这项实验工作与其他分项目的结果结合起来，将对纤维复合材料结构中纳米尺度颗粒的潜力进行全面评估。
