Lightweight body-in-white is often based on a mix of materials that causes problems in the production process. More specifically, the paint oven process after cathodic dip-coating can lead to damaged adhesive layers due to mismatches in thermal expansion of the materials. The understanding of the curing behavior of the structural adhesive cured in this oven process is of crucial interest to determine the damaging in numerical analyses. Therefore, the curing behavior of a one-component toughened hot curing structural adhesive is modeled using three model-based and a model-free approach as well as experimental data from differential scanning calorimetry. After the parameter identification of the models, the parameters are validated using an oven-process-like temperature profile to compare experimental and numerical data.

模拟增韧热固化环氧粘合剂在油漆干燥过程中的固化行为

轻质白车身通常基于在生产过程中导致问题的材料混合。更具体地说,由于材料热膨胀不匹配,阴极浸涂后的烤漆炉工艺会导致粘合剂层受损。了解在此烘箱过程中固化的结构粘合剂的固化行为对于确定数值分析中的损坏至关重要。因此,使用三种基于模型和无模型的方法以及差示扫描量热法的实验数据对单组分增韧热固化结构粘合剂的固化行为进行建模。在模型的参数识别之后,使用类似烤箱过程的温度曲线来验证参数以比较实验和数值数据。
