Four specimen types were examined: CFRP\u2013aluminum alloy two-bolt single-lap joints (TBSL), two-bolt double-lap joints (TBDL), two-bolt bonded\u2013bolted hybrid single-lap joints (BBSL), and two-bolt bonded\u2013bolted hybrid double-lap joints (BBDL). The analysis reveals that double-lap joints possess a markedly higher strength than single-lap joints. The ultimate loads of the TBSL (single-lap joints) at temperatures of \u221240 \u00b0C and 25 \u00b0C are 29.5% and 26.20% lower, respectively, than those of the TBDL (double-lap joints). Similarly, the ultimate loads of the BBSL (hybrid single-lap joints) at \u221240 \u00b0C, 25 \u00b0C, and 80 \u00b0C are 19.8%, 31.66%, and 40.05% lower, respectively, compared to the corresponding data of the TBDL. In bolted\u2013bonded hybrid connections, the adhesive layer enhances the joint\u2019s overall stiffness but exhibits significant temperature dependence. At room and low temperatures, the ultimate loads of the BBDL are 46.97 kN at \u221240 \u00b0C and 50.30 kN at 25 \u00b0C, which are significantly higher than those of the TBDL (42.24 kN and 44.63 kN, respectively). However, at high temperatures, the load\u2013displacement curves of the BBDL and TBDL are nearly identical. This suggests that the adhesive layers are unable to provide a sufficient shear-bearing capacity due to their low modulus at elevated temperatures. This research provides valuable insights for designing composite\u2013metal connections in aircraft structures, highlighting the impacts of different joint configurations and temperature conditions on failure modes and load-bearing capacities.<\/jats:p>","DOI":"10.3390\/ma18153467","type":"journal-article","created":{"date-parts":[[2025,7,24]],"date-time":"2025-07-24T10:28:09Z","timestamp":1753352889000},"page":"3467","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Experimental Investigation of Failure Behaviors of CFRP\u2013Al Lap Joints with Various Configurations Under High- and Low-Temperature Conditions"],"prefix":"10.3390","volume":"18","author":[{"given":"Mingzhen","family":"Wang","sequence":"first","affiliation":[{"name":"College of Aerospace Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"},{"name":"China Special Aircraft Research Institute, Jingmen 448035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiaosheng","family":"Huang","sequence":"additional","affiliation":[{"name":"China Energy Science and Technology Research Institute Co., Ltd., Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-6731-3726","authenticated-orcid":false,"given":"Qingfeng","family":"Duan","sequence":"additional","affiliation":[{"name":"School of Mechanical and Aerospace Engineering, Nanyang Technological University, Singapore 639798, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wentao","family":"Yang","sequence":"additional","affiliation":[{"name":"China Special Aircraft Research Institute, Jingmen 448035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yue","family":"Cui","sequence":"additional","affiliation":[{"name":"China Special Aircraft Research Institute, Jingmen 448035, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongqiang","family":"Lyu","sequence":"additional","affiliation":[{"name":"College of Aerospace Engineering, Nanjing University of Aeronautics and Astronautics, Nanjing 210016, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,7,24]]},"reference":[{"key":"ref_1","first-page":"089270572211422","article-title":"Temperature-Dependent modelling of tension, in-Plane shear, and bending behaviour in non-isothermal thermo-Stamping process simulation of unidirectional UHMWPE fibre reinforced thermoplastic TPU composites","volume":"36","author":"Chen","year":"2022","journal-title":"J.
