Abstract The performance of hybrid metal composite parts strongly depends on the properties of the mechanical interface between the two components as well as on the deformation behavior. A combination of different joining mechanisms (e.g. adhesive bonding, mechanical form-fit) offers enhanced interface performance. This paper shows a novel interface concept based on form-fit elements induced by forming. Compared to other joining methods, the forming induced interface structure provides improved strength as well as energy absorption. Shear tests show an increase of up to 40% in shear strength and up to 78% in fracture energy compared to non-structured adhesive bondings.

形成用于制造混合金属复合材料的诱导界面结构

摘要 混合金属复合材料零件的性能在很大程度上取决于两个部件之间机械界面的特性以及变形行为。不同连接机制（例如粘合剂粘合、机械贴合）的组合提供了增强的界面性能。本文展示了一种新的界面概念，它基于由成型引起的形状配合元素。与其他连接方法相比，形成诱导界面结构提供了更高的强度和能量吸收。剪切试验表明，与非结构化粘合剂相比，剪切强度提高了 40%，断裂能提高了 78%。
