Research and test on mechanical properties of adhesive for infrared optical materials

  • 摘要: 胶接是一种较为常用的支撑方式,经常被用于红外透镜和镜框之间的连接,因此研究胶粘剂在各种环境下的力学性能对提高红外光学遥感器的环境适应能力具有极其重要的价值。选择锗和钛合金、硅和殷钢作为两组研究对象,使用环氧胶进行胶接,通过拉伸和剪切测试试验研究其力学性能。首先,介绍了力学性能的测试方法和流程。之后,在仿真分析的基础上,在三种不同环境下对两组测试对象分别进行拉伸和剪切强度测试,试验数据离散性较小,可信度较高。最后,对试验数据进行总结,发现环氧胶拉伸强度是剪切强度的1.4倍,可满足不同材料间胶接固定,具有良好环境适应性。所得到测试数据可作为红外光学遥感器的设计依据使用,应用价值较高。

     

    Abstract: Adhesive bonding is a commonly used support method, which is often used for the connection of infrared lenses and frames. Therefore, it is of great value to research the mechanical properties of adhesive in various environments to improve the environmental adaptability of infrared optical remote sensors. Germanium and titanium alloy, silicon and invar were selected as two groups of research objects, epoxy adhesive was used for bonding, and its mechanical properties were studied by tensile and shear tests. Firstly, the test method and process of mechanical properties were introduced. Then, on the basis of simulation analysis, the tensile and shear strengths of the two groups of test objects were tested in three different environments, and the test data were less discrete and more reliable. At last, the test data were summarized, and it was found that the tensile strength of epoxy adhesive was 1.4 times the shear strength, which could meet the requirements of bonding and fixing between different materials, and had good environmental adaptability. The test data obtained can be used as the basis for the design of infrared optical remote sensing, which has high application value.
