“…18 Due to these properties and excellent castability, the AlSi10Mg alloy is often used in the automotive, aerospace, and military industries. 19 The listed properties also allow the aluminum alloy to be used for the production of almost pore-free components with mechanical properties in the range of the material specification. An individual adjustment of the properties can be realized by subsequent heat treatment.…”

“…As soon as the critical value C crit is reached, it is assumed that the forming capacity is exhausted, which leads to a material separation in the numerical simulation. Exemplary applications of the criterion are presented by Silva et al 18 and an overview of the current state of research on the modeling of damage and fractures is summarized by Schramm et al 19 In addition, the modeling of the flow curves in the context of material characterization for AM materials is dependent on the building direction. 20 It was shown there that the mechanical behavior and formability of additive manufactured 316L differs significantly from commercially available sheet materials.…”

Laser additive manufacturing processes are used for the production of highly complex geometric structures due to their high geometric freedom. Additive manufacturing processes, in particular powder-based selective laser melting, are used to produce metallic additive manufactured components for the automotive and aerospace industries. Different materials are often joined together to realize sustainable lightweight construction. The production of such mixed construction joints is often realized using mechanical joining technology (e.g. self-piercing riveting). However, there is currently very little experience with the mechanical joining of metallic additive manufacturing components. Furthermore, there is insufficient knowledge about the effects that occur during the mechanical joining of additive manufacturing components. In this article, a method is presented to investigate the joinability of additively manufactured components with conventionally manufactured components using a numerical simulation of the self-piercing riveting process. For this purpose, the additive manufacturing materials are characterized experimentally, the simulation model is configured, and the joining process with additive manufacturing materials is represented in the numerical simulation. Furthermore, the influence of the building direction on the mechanical properties is shown using miniature tensile specimens. Besides the configuration of the simulation model, the influence of heat treatment on the self-piercing riveting process is presented.

“…The aggregate state of the matrix can also influence the deformation and failure behavior of the composite material. Therefore, when modeling the clinching of CFRP with metal material, considerations should include fiber reorientation, fiber displacement, and the heterogeneous distribution of fibers and matrix [73]. Currently, there are four methods for heating the joining partners during clinching.…”

The extensive use of carbon fiber-reinforced composites and aluminum alloys represents the highest level of automotive body-in-white lightweighting. The effective and secure joining of these heterogeneous materials remains a prominent and actively researched topic within the scientific community. Among various joining techniques, clinching has emerged as a particularly cost-effective solution, experiencing significant advancements. However, the application of clinching is severely limited by the properties of the joining materials. In this work, various clinching processes for the joining of composites and aluminum alloys reported in recent research are described in detail according to three broad categories based on the principle of technological improvement. By scrutinizing current clinching technologies, a forward-looking perspective is presented for the future evolution of clinching technology in terms of composite–aluminum joints, encompassing aspects of tool design, process analysis, and the enhancement of joint quality. This work provides an overview of current research on clinching of CFRP and aluminum and serves as a reference for the further development of clinching processes.
