选择80℃/95%RH的湿热老化环境对铝合金-玄武岩纤维增强聚合物复合材料(Al-BFRP)、Al-Al、BFRP-BFRP单搭接接头进行老化试验。分析了对接头失效强度、失效位移和失效模式的影响。采用傅里叶变换红外光谱（FTIR）测试了粘合剂和BFRP化学基团的变化。通过扫描电子显微镜（SEM）观察失效断面的显微组织。结果表明，Al-Al接头的失效位移低于Al-BFRP和BFRP-BFRP接头。 Al-BFRP接头的失效强度低于Al-Al接头，高于BFRP-BFRP接头，且时效过程中Al-BFRP接头的失效强度下降率最高。胶粘剂的力学性能减弱，胶粘表面纤维撕裂比例下降。未老化的Al-Al接头的失效模式是粘结力。时效Al-Al接头的失效模式表现为界面失效从边缘向中心扩展，导致失效强度下降。
The hygrothermal aging environment of 80°C/95%RH was selected to conduct the aging tests on single lap joints of aluminum alloy-basalt fiber reinforced polymer composite(Al-BFRP),Al-Al, and BFRP-BFRP. The effects on the failure strength, failure displacement and failure modes of the joints were analyzed. Fourier transform infrared spectroscopy (FTIR) was used to test the changes of chemical groups of adhesive and BFRP. The microstructure of the failure section was observed by scanning electron microscope (SEM). The results show that the failure displacement of the Al-Al joints is lower than that of the Al-BFRP and BFRP-BFRP joints. The failure strength of Al-BFRP joints is lower than that of Al-Al joints and higher than that of BFRP-BFRP joints, while the decline rate of failure strength of Al-BFRP joints during aging is the highest. The mechanical properties of the adhesive were weakened and the fiber tear proportion on the bonding surface decreased. The failure mode of unaged Al-Al joint is adhesive cohesion. The failure mode of aged Al-Al joint appears the interface failure spreading from the edge to the center, leading to the decrease of the failure strength.
