摘要/Abstract

摘要： 主要对玻璃纤维增强树脂基复合材料碾铆-粘接接头进行了老化和腐蚀试验,通过静拉伸测试,分析了温度和腐蚀介质对混合连接接头力学性能的影响。结果表明:同温下,粘接层失效时的峰值载荷会随保温时间的增加而减小;同保温时间下,粘接层失效时的峰值载荷会随温度的增加而减小;在5%NaCl溶液中腐蚀时,连接件的抗拉伸性能受腐蚀时间延长的影响比较小;而在5%NaOH溶液和5%HNO₃溶液中腐蚀时,连接件的抗拉伸性能受到的影响比较大,样件的峰值载荷下降比较明显。试样的失效主要分为胶层失效和铆钉拉脱失效两个阶段。

Abstract: In this paper, the aging and corrosion tests of the glass fiber reinforced polymer (GFRP) with hybrid joints (rolling riveting/bonding) were carried out. The effects of temperature and corrosion medium on the mechanical properties of the joint were analyzed by static tensile test. The experiment results show that the peak load of the adhesive layer decreases with the increase of holding time at the same temperature, and the peak load of the adhesive layer decreases with the increase of temperature at the same holding time. Furthermore, in 5% NaCl solution, corrosion resistance has little influence on the tensile properties of the connector when the corrosion time is prolonged. But when corrosion was carried out in 5% NaOH solution and 5% HNO₃ solution, the tensile properties of the joints are greatly affected, and the peak load of the samples are decreased obviously. The failure of the sample is mainly divided into two gradations of the adhesive failure and rivet failure.

Key words: GFRP, aging, corrosion, hybrid joints, tensile property
