摘要

为了给铝合金-玄武岩纤维增强树脂复合材料(BFRP)粘接结构在汽车工业中的应用提供参考和指导，制作了铝合金-BFRP粘接接头，分别在1、50、100mm/min低速加载速率下进行准静态拉伸试验与剪切试验.结合汽车服役中的温度区间，在80℃的高温老化环境下对接头进行0、5、10、15、20d的老化实验.对老化的接头进行加载速率为1、100mm/min的准静态拉伸试验与剪切试验，得到不同老化时间下铝合金-BFRP粘接接头的准静态失效强度.结合宏观模式与扫描电子显微镜分析研究接头失效模式的变化，结果表明：铝合金-BFRP粘接接头失效强度由加载速率和老化时间共同影响.低速加载过程，接头在拉应力和切应力作用下的失效强度均随加载速率的增大而升高；在加载速率范围内，切应力作用下接头失效强度的上升幅度大于拉应力作用下的；3种低速加载速率测试中，拉应力和切应力作用下接头的失效模式分别为纤维撕裂和胶层内聚，未老化接头的宏观失效模式无明显变化.本研究对高温环境下服役的粘接结构准静态的失效预测具有工程意义.

Abstract

In order to provide reference and guidance for the application of bonded structure of aluminum alloy-basalt fiber reinforced polymer composite (BFRP) in the automobile industry, the aluminum alloy-BFRP bonded joints were made, and the quasi-static tensile and shear tests were conducted at the low speed loading rates of 1, 50, and 100mm/min. The aging days of 0, 5,10,15, and 20 at 80℃ was selected in combination with the temperature range in service of automobile. The quasi-static tensile and shear tests at loading rates of 1 and 100mm/min were performed for aged joints, and the quasi-static failure strength on different aging days was obtained. The failure mode of joints was studied by means of macroscopic and SEM analyses. The results show that the failure strength of aluminum alloy-BFRP bonded joints is affected by the loading rate and aging time. In the process of low speed loading, the failure strength at tensile stress and shear stress increases with the increases in loading rate. In the range of loading rate, the increase in failure strength at shear stress is larger than that at tensile stress. In the three low speed loading rate tests, the failure modes at tensile stress and shear stress are fiber tearing and adhesive layer cohesion, respectively. Low speed loading rate has no obvious effect on the macro failure mode of unaged joints. This study is of engineering significance for the quasi-static failure prediction of adhesive structures in high temperature service.

Key words： basalt fiber reinforced polymer composite; adhesive bonding; loading rate; high temperature; aging; failure prediction
