1.Advanced composite materials: BMI, as a high-performance thermosetting resin, is often used as the matrix of advanced composite materials in the aerospace field. It is combined with high-performance reinforcing materials such as carbon fiber and glass fiber to form composite materials with excellent mechanical properties and thermal stability. These composite materials are widely used in the aerospace field for key structural components of aircraft, helicopters and spacecraft, such as wings, fuselages, tails and engine nacelles.
2.High temperature engine components: BMI has excellent high temperature resistance and can withstand extremely high temperatures without thermal decomposition or thermal oxidation. Therefore, it is often used to manufacture key components in aerospace engines, such as combustion chambers, turbine blades and nozzles. These components need to withstand high temperatures and extreme mechanical stress, and the high temperature resistance of BMI ensures the reliability and long life of these components.
3.Thermal protection system: In the aerospace field, thermal protection system is an important part of protecting spacecraft and aircraft from high temperature damage. BMI is widely used in the manufacture of thermal protection systems due to its excellent high temperature resistance and low thermal expansion coefficient. It can be made into thermal insulation tiles, thermal resistance materials and thermal shielding layers, etc., which can effectively reduce heat transfer and protect key components of aerospace vehicles from damage in high-temperature environments.
4.Lightweight structural materials: BMI has the characteristics of low density and high strength, so it is suitable for manufacturing lightweight structural materials. In the aerospace industry, reducing structural weight is a key factor in improving fuel efficiency and performance. The lightweight structural materials made by BMI can replace traditional metal materials, reduce the weight of aerospace vehicles, and improve overall performance.
5.Aerospace electronic equipment: BMI has good electrical insulation and dielectric properties and is suitable for the manufacturing of aerospace electronic equipment. It can be used to manufacture circuit boards, packaging materials, insulation layers, etc. to ensure the normal operation and reliability of aerospace electronic equipment.
N,N'-4,4'-Diphenylmethylene bismaleimide (BMI, CAS No. 13676-54-5), as a thermosetting resin with excellent performance, has been widely used in the aerospace field. Its excellent high temperature resistance, mechanical properties and chemical stability make it an ideal choice for key components in the aerospace field, providing important support for the development of aerospace technology.
