In this paper, Araldite\u00ae 2012 adhesive was used to bond basalt-fiber-reinforced polymer (BFRP), and the durability of its bonded joints was investigated. Experiments were carried out at 80 \u00b0C\/DI water (deionized water), 80 \u00b0C\/3.5% NaCl solution (3.5% SS), and 80 \u00b0C\/5.0% NaCl solution (5.0% SS) at 0- (unaged), 10-, 20-, and 30-day aging. The specimen and BFRP in the environment of 80 \u00b0C\/DI water, 80 \u00b0C\/3.5% SS, and 80 \u00b0C\/5.0% SS found salt solution under the condition of all sample water absorption decreases, and the activity of salt solution chemistry was weaker compared with deionized water. The load\u2013displacement curve of the joint failure was obtained through quasi-static tensile experiments, and it was found that the adhesive would undergo a post-curing reaction that had a positive impact on the stiffness of the joint in a high-temperature environment. At the same time, it was found that the joint failure strength decreased less in the salt solution environment, and deionized water was more destructive than the salt solution. Referring to the change in water absorption, it was found that the change in the mechanical properties of the joint was mainly related to the permeation effect of the polymer. The change in the Tg of adhesive was measured by differential scanning calorimetry (DSC). It was found that Tg would decrease after aging, and the change in Tg was mainly related to the mobility of the molecular chain. Thermogravimetric analysis (TGA) was used to analyze the thermal behavior of the epoxy resin and some organic matter, and the main weight loss stage was 340\u2013450 \u00b0C, which was the complete degradation of epoxy resin and some organic matter. Macro visual and microscopic scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX) were used to analyze the failure section, and it can be concluded that the failure mode of joint tear failure transitioned to cohesion in the late\u2013mixed interface failure, at the visible interface between the fiber and the resin matrix.<\/jats:p>","DOI":"10.3390\/polym14112250","type":"journal-article","created":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T03:33:18Z","timestamp":1654054398000},"page":"2250","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Study on the Effect of Salt Solution on Durability of Basalt-Fiber-Reinforced Polymer Joints in High-Temperature Environment"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8275-621X","authenticated-orcid":false,"given":"Yisa","family":"Fan","sequence":"first","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450045, China"},{"name":"International Joint Laboratory of Thermo-Fluid Electro-Chemical System for New Energy Vehicle, 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 450045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ye","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhen","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, North China University of Water Resources and Electric Power, Zhengzhou 450045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gaolei","family":"Xi","sequence":"additional","affiliation":[{"name":"Technology Center for China Tobacco Henan Industrial Limited Company, 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 450045, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s00170-014-6197-5","article-title":"Experimental analysis of damage propagation in riveted CFRP-steel structures by thermal loads","volume":"75","author":"Wagner","year":"2014","journal-title":"Int.
