Abstract: 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 17mm bonding width and 4mm sagging structure, polished by 180# emery cloth, owns the best performance. Through the fatigue experiments, it is found that the specimen with 25mm×17mm, 0mm 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.

Key words: Roughness; bonding width; edge structure; fatigue
