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.","lang":"eng"}],"status":"public","type":"journal_article","publication":"The Journal of Adhesion","title":"Correlation between interlaminar shear strength of CFRP and joint strength of aluminium-CFRP hybrid joints","main_file_link":[{"open_access":"1","url":"https://www.tandfonline.com/doi/full/10.1080/00218464.2024.2439956?src="}],"doi":"10.1080/00218464.2024.2439956","oa":"1","date_updated":"2026-02-20T12:49:17Z","publisher":"Informa UK Limited","date_created":"2025-01-13T08:16:46Z","author":[{"first_name":"Shuang","id":"48039","full_name":"Wu, Shuang","orcid":"0000-0001-8645-9952","last_name":"Wu"},{"first_name":"Alexander","last_name":"Delp","full_name":"Delp, Alexander"},{"first_name":"Jonathan","last_name":"Freund","full_name":"Freund, Jonathan"},{"first_name":"Frank","last_name":"Walther","full_name":"Walther, Frank"},{"first_name":"Jan","last_name":"Haubrich","full_name":"Haubrich, Jan"},{"first_name":"Miriam","last_name":"Löbbecke","full_name":"Löbbecke, Miriam"},{"full_name":"Tröster, Thomas","id":"553","last_name":"Tröster","first_name":"Thomas"}],"year":"2025","citation":{"ieee":"S.

Comparative linear sweep voltammetry was employed on the first and seventh day of the corrosion experiment. The influence of different laser morphologies and production process parameters on corrosion behavior was compared. The corrosion reaction mainly arises from the aluminum component and shows distinct differences in long-term corrosion morphology between pure EN AW-6082 and the hybrid laminate. Compared to short-term investigations, a strong influence of galvanic corrosion on the interface is assumed. No distinct influences of different laser structuring and process parameters on the corrosion behavior were detected.

Single-lap shear tests were performed on hybrid AW 6082-T6–CFRP specimens pretreated with the same pulsed laser surface parameter sets on the metal surface as previously tested, AW 6082-T6–E320 metal adhesive joints. The fracture surfaces were characterized to determine the type of failure and elucidate differences and commonalities in the link between surface structures and single-lap shear strengths. Digital image analyses of the hybrid specimens’ fractured surfaces were used to quantify remaining CFRP fragments on the metallic joint side. The results indicate that high surface enlargements and the presence of undercut structures lead to single-lap shear strengths exceeding 40 MPa and 35 MPa for unaged and aged hybrid specimens, respectively. Whereas for the metal–polymer joints, the trend from high strength to weakly bonded specimens is largely continuous with the degree of surface structuring, hybrid metal–CFRP joints exhibit a drastic drop in joint performance after aging if the laser-generated surface structures are less pronounced with low surface enlargements and crater depths. Surface features and hydrothermal aging determine whether the specimens fail cohesively or adhesively.</jats:p>"}],"language":[{"iso":"eng"}],"quality_controlled":"1","issue":"10","year":"2023","publisher":"MDPI AG","date_created":"2024-08-26T10:45:05Z","title":"Transferability of the Structure–Property Relationships from Laser-Pretreated Metal–Polymer Joints to Aluminum–CFRP Hybrid Joints"},{"_id":"46495","user_id":"48039","department":[{"_id":"321"},{"_id":"149"},{"_id":"9"}],"article_type":"original","type":"journal_article","status":"public","date_updated":"2025-01-30T12:33:42Z","author":[{"last_name":"Wu","orcid":"0000-0001-8645-9952","full_name":"Wu, Shuang","id":"48039","first_name":"Shuang"},{"first_name":"Alexander","full_name":"Delp, Alexander","last_name":"Delp"},{"first_name":"Jonathan","last_name":"Freund","full_name":"Freund, Jonathan"},{"full_name":"Walther, Frank","last_name":"Walther","first_name":"Frank"},{"last_name":"Haubrich","full_name":"Haubrich, Jan","first_name":"Jan"},{"first_name":"Miriam","last_name":"Löbbecke","full_name":"Löbbecke, Miriam"},{"first_name":"Thomas","last_name":"Tröster","id":"553","full_name":"Tröster, Thomas"}],"doi":"10.1080/00218464.2023.2245758","publication_status":"published","publication_identifier":{"issn":["0021-8464","1545-5823"]},"citation":{"bibtex":"@article{Wu_Delp_Freund_Walther_Haubrich_Löbbecke_Tröster_2023, title={Adhesion properties of the hybrid system made of laser-structured aluminium EN AW 6082 and CFRP by co-bonding-pressing process}, DOI={<a href=\"https://doi.org/10.1080/00218464.2023.2245758\">10.1080/00218464.2023.2245758</a>}, journal={The Journal of Adhesion}, publisher={Informa UK Limited}, author={Wu, Shuang and Delp, Alexander and Freund, Jonathan and Walther, Frank and Haubrich, Jan and Löbbecke, Miriam and Tröster, Thomas}, year={2023}, pages={1–29} }","mla":"Wu, Shuang, et al. “Adhesion Properties of the Hybrid System Made of Laser-Structured Aluminium EN AW 6082 and CFRP by Co-Bonding-Pressing Process.” <i>The Journal of Adhesion</i>, Informa UK Limited, 2023, pp. 1–29, doi:<a href=\"https://doi.org/10.1080/00218464.2023.2245758\">10.1080/00218464.2023.2245758</a>.","short":"S.

The optimal CFRP layer structure was calculated in advance using the finite element method. During the forming process, the curing reaction and the joining of the aluminium sheet and CFRP prepreg will take place simultaneously.

Pristine and hybridized specimens were corroded in aqueous NaCl electrolyte (0.1 mol/l) using a potentiodynamic polarization technique and subsequently analyzed using computed tomography, scanning electron-, light- and laser scanning microscopy. The results show that the corrosive reaction arises mainly from the aluminum component. Surface pretreatment of the aluminum resulted in increasing corrosion rates, but showed no influence on the hybrids corrosion properties. Optical micrographs suggest that the epoxy resin acts as a sealant preventing galvanic corrosion between the aluminum and carbon fibers by hindering the diffusion of the electrolyte into the joints.
