摘　　要：对J-189胶黏剂使用过程中关于试件打磨砂布目数、试件粘接宽度、边缘结构等方面的力学性能参数进行实验论证,得出180目砂布打磨、17mm粘接宽度、4mm下陷结构试件力学性能最佳的结论。通过疲劳实验,确定25mm×17mm、0mm下陷边缘结构疲劳力学性能最佳。对飞机风挡软连接粘接区表面粗糙度、粘接宽度、边缘结构等边缘连接方面提供关键工艺参数。A series of mechanical property parameters, such as emery cloth mesh number, specimen bonding width, and edge structure during the use of J-189 adhesive were experimentally demonstrated, and it is found that the specimen with the 17 mm bonding width and 4 mm sagging structure,polished by 180# emery cloth, owns the best performance. Through the fatigue experiments, it is found that the specimen with 25 mm ×17 mm, 0 mm sagging edge structure has the best mechanical properties. The key technical parameters of the edge bonding for aircraft windshield soft joint adhesion are provided, such as the surface roughness, bonding width and edge structure.
