The aim of the project is to develop basic insights on the influence of morphology on the cyclic dynamic load behaviour of foam injection molded thermoplastics. Cyclic dynamic tensile and bending tests should be carried out on structural foams with process-related compact skin layers and integrally foamed core areas. By the help of new process technology (precision mold-opening), test specimens with different structural characteristics (foaming ratio, cell size, cell density, cell distance, thickness of the compact skin layer, etc.) should be produced specifically for this purpose. To quantify the deformation and failure behaviour, optical measurement technology (ARAMIS, GOM + mobile optical light microscopy) should also be used during the mechanical tests. The results should be correlated with the structure in order to gain fundamental insights into the relationship between deformation and fracture mechanisms and structural parameters.

该项目的目的是发展基本的见解形态的影响，循环动态载荷行为的泡沫注塑成型的热塑性塑料。应对具有与工艺相关的致密表层和整体发泡芯区的结构泡沫进行循环动态拉伸和弯曲试验。借助新的工艺技术（精密开模），可以制备出具有不同结构特征（发泡率、泡孔尺寸、泡孔密度、泡孔间距、致密皮层厚度等）的试样。应专门为此目的而生产。为了量化变形和失效行为，还应在机械试验期间使用光学测量技术（ARAMIS、GOM +移动的光学显微镜）。结果应与结构，以获得变形和断裂机制和结构参数之间的关系的基本见解。
