摩擦压接是一种创新的连接工艺，用于生产无添加剂的塑料-金属搭接结构。为了获得高的结合强度，金属连接件通过激光辐射进行预处理。随后，在连接过程中通过摩擦和压力引起热量，导致热塑性材料熔化并粘附到金属连接伙伴。在这项工作中，在复合材料的过程中的温度分布进行了分析和表征。结果发现，发生的温度和温差不仅取决于转速，而且对进给速度。它还表明，摩擦表面温度可以被用作一个间接的控制变量，基于模型的闭环控制。基于这些发现，各种表面改性的金属连接伙伴进行了调查和分析方面的最大强度的关节。据观察，最高的拉伸剪切强度可以实现与准混沌纳米结构。此外，连接化合物的特点是一个薄的部分，有利于识别特定区域的关节。这些研究表明，塑料和金属的摩擦压力连接的高潜力，并形成基于模型的连接区温度控制的基础。
Friction press joining is an innovative joining process for the production of plastic-metal joints without additives, in an overlap configuration. In order to achieve a high bond strength, the metallic joining partner is pretreated with laser radiation. Subsequently, heat is induced by friction and pressure during the joining process, causing the thermoplastic material to melt and adhere to the metallic joining partner. In this work, the temperature distribution during the process in the composite is analyzed and characterized. It was found that the occurring temperatures and temperature differences are not only dependent on the rotational speed, but also on the feed rate. It is also shown that the friction surface temperature can be used as an indirect control variable for a model-based, closed-loop control. Based on these findings, various surface modifications for the metallic joining partner were investigated and analyzed with regard to the maximum strength of the joint. It was observed that the highest tensile shear strength can be achieved with a quasi-chaotic nano structure. In addition, the joining compound was characterized by a thin section, facilitating the identification of specific zones in the joint. These investigations show the high potential for friction press joining of plastics and metals, and form the basis for a model-based control of the joining zone temperature.
