Since the Wright brothers' first aircraft was introduced over 100 years ago, the reduction of structural mass coefficient, extension of lifespan, and improvement of speed and efficiency in each generation of aircraft have all strongly relied on advances in materials science and technology. The first generation of materials and the first generation of aircraft fully reflect the pioneering and fundamental role of new material technology in the development of the aviation industry.

Organic silicon materials have many excellent properties. They are typical semi inorganic and semi organic polymer materials, combining the characteristics of inorganic and organic polymer materials. Therefore, they have unique properties such as high and low temperature resistance, oxygen resistance, light resistance, and weather aging resistance, and have been widely used in the aviation industry.

There are many types of silicone rubber used in the aviation industry, which can be divided into room temperature vulcanized silicone rubber (including condensation type silicone rubber and addition type silicone rubber) and heat vulcanized silicone rubber according to their vulcanization methods. In addition, there are also non vulcanized silicone rubber. According to their functions, they can be divided into fluid sealing materials such as oil tight, air tight, and water tight, vibration damping and noise reduction materials such as vibration isolation and absorption, materials such as thermal conductivity, insulation, and heat insulation, electromagnetic shielding and stealth materials such as conductive, magnetic, and absorbing materials, and safety protection materials such as flame retardant and fireproof materials.

Damping and vibration reducing rubber is a type of material that utilizes the damping characteristics of rubber to improve vibration prevention and reduction effects. It can effectively avoid electronic device failure and instrument failure, greatly increase the service life of mechanical components, and thus improve the accuracy and reliability of aircraft equipment. The glass transition temperature of silicone rubber is relatively low, and there is little change in performance values near room temperature. However, the main chain silicon oxide structure makes its mechanical properties more stable in a wide temperature range (-50-200 ℃).

Traditional damping and vibration reduction materials often have a narrow temperature and frequency range, which cannot adapt to the wide frequency range of low-frequency and high-frequency vibrations during aircraft start-up and operation. They are also difficult to accommodate the wide working temperature range of cold winters in the north and hot summers in the south. Therefore, silicone rubber is often the preferred damping material in the aviation industry, especially in situations where high heat is generated due to high stress and strain.
