Fabrication of higher hierarchical levels of material systems with fluidized bed granulation and discrete-element modeling of the materials (A03)

在TP A3的范围内，更高层次的材料系统在喷淋床上进行喷雾造粒，然后进行温压实步骤。事实证明，喷淋床法非常适合于用聚合物均匀涂覆细铜或陶瓷颗粒。作为这些材料系统的进一步生产方法，喷雾干燥工艺将被研究。为了确定复合材料的力学性能，进行了弯曲试验，并通过热重、扫描电镜和FIB分析了复合材料的组成和结构。此外，涂层过程已经并将使用CFD-DEM进行建模和优化。弯曲试验将使用内部开发的DEM软件工具MUSEN进行建模，以量化成分和颗粒形状对复合材料力学性能的影响。

Within the scope of TP A3, higher hierarchical levels of material systems are assembled with spray granulation in a spouted bed following a warm compaction step. The spouted bed method proved to be very suitable for uniform coating of fine copper or ceramic particles with polymers. As a further production method of these material systems the spray-drying process will be investigated. For the determination of the mechanical properties of the composites, bending test are carried out and their composition and structure are investigated by thermogravimetry, SEM and FIB. In addition, the coating process is and will be modeled and optimized using CFD-DEM. The bending tests will be modeled using the inhouse developed DEM software tool MUSEN to quantify the influence of the composition and the particle shape on the mechanical properties of the composite.
