With the rapid development of modern science and technology, the selection of aerospace materials is more stringent, launch vehicles, intercontinental missiles, space shuttles and other space launch vehicles are developing in the direction of light weight, good reliability, long life and low energy consumption, and the use of adhesives with excellent performance and their corresponding bonding technology has become one of the effective sections of spacecraft to improve efficiency. The use of adhesives in aerospace products has become more and more widespread, mainly because aerospace products mostly use light alloys, honeycomb structures and conforming materials. In addition, the use environment of aerospace products is harsh, and the requirements for adhesives are also higher, which need to be able to withstand environmental tests such as ultra-high temperature, ultra-low temperature, temperature alternation, high vacuum, thermal cycling, ultraviolet rays, charged particles, micrometeorites, and atomic oxygen
