摘要: 研究了自制中温胶膜J-12和西锐SR20复合材料维修手册提供的AF-163-2M中温胶膜的固化工艺、力学性能及使用温度差异。结果显示:两胶膜在120 ℃~130 ℃时具有较好的固化速率,均能在150 ℃长期使用,满足SR20复合材粘接维修需要;室温下J-12胶膜固化物AF-163-2M胶膜单搭接拉伸剪切强度分别为30.1 MPa、27.4 MPa,J-12胶膜固化物的剪切强度优于AF-163-2M胶膜固化物。综上所述,国产J-12胶膜性能与AF-163-2M胶膜性能相当,可作为替代性产品应用于西锐SR20复合材料粘接维修。

Abstract: The differences between the curing process, mechanical properties and temperature of J-12 medium-temperature adhesive film were compared with those of AF-163-2M which was suggested to use in bonding repair of Cirrus SR20 composites. It was found that those two adhesive films have good curing rate between 120 ℃ and 130 ℃, and both of them could maintain good mechanical properties at 150 ℃ and meet the maintenance needs of Cirrus SR20 composites. The single lap shear tensile strength of cured J-12 adhesive film and AF-163-2M film were 30.1 MPa and 27.4 MPa at room temperature, respectively. The shear strength of cured J-12 film is better than that of cured AF-163-2M film. To sum up, the comprehensive performances of J-12 adhesive film are similar to those of AF-163-2M adhesive film, which could be used as an alternative product used in the Cirrus SR20 composites bonding repairing.
