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

子项目6位于2021研究组过程链的末端。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的研究之外，重点不是在纯材料水平上，而是在更复杂结构的研究上。特别是不断增加的几何复杂性对无端纤维增强复合材料的可制造性和性能的影响进行了研究。其目的是研究几何形状具有挑战性的组件是否存在影响，例如通过改变应力状态或在简单试样中未观察到的局部不同纤维压实。作为示例性结构细节，观察到支架和作为更复杂的部件的C形框架。特别关注注塑行为、损伤容限（冲击性能）和脱模后部件的尺寸稳定性。通过将这项实验工作与其他子项目的结果合并，将对纤维复合材料结构中纳米级颗粒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.
