--- _id: '58163' abstract: - lang: eng text: Fibre-reinforced polymers are increasingly used due to their high specific strength, making them suitable for local sheet metal reinforcement. This allows improved overall mechanical properties with reduced wall thickness of the sheet metal part and, thus, lower weight of the components. One of the main focuses of research into such hybrid structures is on the adhesive properties and the respective failure behaviour of the interfaces. Generally, the failure behaviour under the influence of mechanical loads can be divided into adhesive, cohesive and mixed-mode failure. The correlation between observed failure behaviour and adhesion properties of the hybrid composite materials is analysed in detail in this work. The hybrid composite consists of an aluminium sheet of the alloy EN AW‑6082 T6 and thermoset carbon fibre-reinforced plastic (CFRP) prepreg. The aluminium sheet was laser pretreated before hybrid production to improve the adhesion properties. The specimens studied were produced by the prepreg pressing process, in which the components are cured and joined simultaneously. The influences of the thickness of the CFRP part, the layup, the fibre orientation at the boundary layer, and the laser pretreatment parameters on the properties of the hybrid joints were investigated. article_type: original author: - first_name: Shuang full_name: Wu, Shuang id: '48039' last_name: Wu orcid: 0000-0001-8645-9952 - first_name: Alexander full_name: Delp, Alexander last_name: Delp - first_name: Jonathan full_name: Freund, Jonathan last_name: Freund - first_name: Frank full_name: Walther, Frank last_name: Walther - first_name: Jan full_name: Haubrich, Jan last_name: Haubrich - first_name: Miriam full_name: Löbbecke, Miriam last_name: Löbbecke - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Wu S, Delp A, Freund J, et al.

These two components can therefore be joined using the intrinsic joining technique, which is formed by curing the matrix of the FRP component. In this study, for the hybrid joint, unidirectionally pre-impregnated semi-finished products (prepregs) with duromer matrix resin and micro-alloyed HC340LA steel were used. In order to conduct a detailed investigation, the damage mechanisms of intrinsically produced fibre metal laminates (FMLs), a new clamping device, and a novel pressing tool were designed and put into operation. The prepregs were prestressed by applying a preloading force using a specially designed prestressing frame. Hybrid specimens were then produced and subjected to nanoindentation and a shear tensile test. In particular, the effect of the residual stress state by varying the defined prestressing force on the damage mechanisms was studied. The results showed that no fracture patterns occurred in the interface of the specimens without preloading as a result of curing at 120 °C, whereas specimens with preloading failed at the boundary layer in the tensile range. Nevertheless, all specimens cured at 160 °C failed at the boundary layer in the tensile range. Furthermore, it was proven that the force and displacement of the preloaded specimens were promisingly higher than those of the unpreloaded specimens. article_number: '316' article_type: original author: - first_name: Hayrettin full_name: Irmak, Hayrettin id: '75657' last_name: Irmak orcid: https://orcid.org/0009-0009-6267-2957 - first_name: Steffen Rainer full_name: Tinkloh, Steffen Rainer id: '72722' last_name: Tinkloh - first_name: Thorsten full_name: Marten, Thorsten id: '338' last_name: Marten orcid: 0009-0001-6433-7839 - first_name: Thomas full_name: Tröster, Thomas id: '553' last_name: Tröster citation: ama: Irmak H, Tinkloh SR, Marten T, Tröster T.
