Not any polymer is ready for use after synthesis. Later particular applications usually require a more or less addition of fillers. Anisometric fillers (fibers and platelets) cause anisotropic part properties. These properties are usually predicted by means of simulation. The central model in these simulations is the Folgar-Tucker model, which describes process-depending filler orientation. As described in literature, the Folgar-Tucker model and its most imported parameter, the interaction coefficient, were only validated for fibrous fillers.At the moment, no knowledge about the orientation behavior of filler blends and its interaction mechanisms between different fillers exists. Thus, the goals of this research proposal are to investigate the orientation behavior of filler blends as well as the prevalent interaction mechanisms systematically. Based on this, the Folgar-Tucker model will be adapted to describe the filler orientation of filler blends. These adaptions will afterwards be validated at concrete plastic parts.

并非任何聚合物在合成后就可以使用。后来的特定应用通常需要或多或少添加填料。不等轴填料（纤维和片晶）会导致零件特性各向异性。这些特性通常通过模拟的方式来预测。这些模拟中的核心模型是 Folgar-Tucker 模型，它描述了取决于工艺的填料方向。正如文献中所述，Folgar-Tucker 模型及其最重要的参数（相互作用系数）仅针对纤维填料进行了验证。目前，尚不清楚填料共混物的取向行为及其不同填料之间的相互作用机制。因此，本研究计划的目标是系统地研究填料共混物的取向行为以及普遍的相互作用机制。在此基础上，Folgar-Tucker 模型将适用于描述填料共混物的填料取向。这些调整随后将在混凝土塑料部件上得到验证。
