    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.
