Enhancement of the Folgar-Tucker model to predict filler orientation of filler blends and its application in the process simulation

不是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地添加填料。非等轴填料（纤维和血小板）导致各向异性的部分属性。这些特性通常通过模拟来预测。这些模拟中的中心模型是Folgar-Tucker模型，该模型描述了取决于工艺的填料取向。如文献所述，Folgar-Tucker模型及其最重要的参数--相互作用系数仅针对纤维状填料进行了验证，目前对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还没有认识。因此，本研究的目的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。这些调整之后将在混凝土塑料部件上进行验证。

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.
