Clinching continuous fibre reinforced thermoplastic composites and metals is challenging due to the low ductility of the composite material. Therefore, a number of novel clinching technologies has been developed specifically for these material combinations. A systematic overview of these advanced clinching methods is given in the present paper. With a focus on process design, three selected clinching methods suitable for different joining tasks are described in detail. The clinching processes including equipment and tools, observed process phenomena and the resultant material structure are compared. Process phenomena during joining are explained in general and compared using computed tomography and micrograph images for each process. In addition the load bearing behaviour and the corresponding failure mechanisms are investigated by means of single-lap shear tests. Finally, the new joining technologies are discussed regarding application relevant criteria.
由于复合材料的低延展性,将连续纤维增强热塑性复合材料与金属进行压铆连接具有挑战性。因此,已经专门为这些材料组合开发了许多新颖的压铆技术。本文对这些先进的压铆方法进行了系统概述。重点关注工艺设计,详细描述了适用于不同连接任务的三种选定压铆方法。比较了包括设备和工具在内的压铆工艺、观察到的工艺现象以及所得材料结构。总体解释了连接过程中的工艺现象,并使用计算机断层扫描和每个工艺的显微照片进行比较。此外,通过单搭接剪切试验研究了承载行为和相应的失效机制。最后,根据与应用相关的标准对新的连接技术进行了讨论。
