In order to study the influence of high temperature and high humidity on the bonding structure between different materials, this paper selects basalt fiber-reinforced resin composite materials (BFRP) and aluminum alloy (Al), and uses Araldite\u00ae 2012 and Araldite\u00ae 2014, two adhesives, to make single lap joints (SLJs). The aging test was carried out for 0 (unaged), 10, 20, and 30 days under the environment of 80 \u00b0C\/95% relative humidity (RH) and 80 \u00b0C\/pure water. In this work, simple Fickian law was used to simulate the hygroscopic change law of dumbbell specimens of two adhesives and BFRP in a pure water environment. It was discovered that Araldite\u00ae 2012 is most affected by moisture, but the time to reach the maximum water absorption in Araldite\u00ae 2014 was shorter than in Araldite\u00ae 2012. The failure strength of the joint was obtained through a quasi-static tensile experiment, and it was found that the Araldite\u00ae 2014 adhesive joint first increased and then decreased in a high temperature environment. The strength increased by 11.63% after 20 days of aging under an 80 \u00b0C\/95%RH environment, and increased by 16.66% after 10 days of aging under an 80 \u00b0C\/pure water environment, which indicates that post-curing reaction occurred. The strength of Araldite\u00ae 2012 joints showed a downward trend. After 30 days of aging, it reduced by 40.38% under an 80 \u00b0C\/95%RH environment and 41.11% under an 80 \u00b0C\/pure water environment. By observing the load-displacement curve, it was found that, as time increased, the slope of the curve decreased, indicating that the stiffness of the bonded joint decreased with time. The failure modes of the joints were analyzed by macroscopic images and microscopic SEM methods, and the results showed that the surface failure transitions from a mixed failure to a complete tear failure over time. The failure of the basalt fiber\/resin interface was because the interaction between the epoxy resin in the adhesive and the epoxy resin in BFRP was greater than the force between the basalt fiber layer and the epoxy resin layer in the BFRP sheet.<\/jats:p>","DOI":"10.3390\/polym13162593","type":"journal-article","created":{"date-parts":[[2021,8,5]],"date-time":"2021-08-05T04:33:29Z","timestamp":1628138009000},"page":"2593","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Comparative Failure Study of Different Bonded Basalt Fiber-Reinforced Polymer (BFRP)-AL Joints in a Humid and Hot Environment"],"prefix":"10.3390","volume":"13","author":[{"given":"Yisa","family":"Fan","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jinzhan","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaopeng","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Xia","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-9684-4038","authenticated-orcid":false,"given":"Peng","family":"Han","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Linjian","family":"Shangguan","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyue","family":"Zhang","sequence":"additional","affiliation":[{"name":"College of Tobacco Science, Henan Agricultural University, Zhengzhou 450002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"74","DOI":"10.1016\/j.compositesb.2014.12.034","article-title":"A review on basalt fibre and its composites","volume":"74","author":"Scalici","year":"2015","journal-title":"Compos.
