1. Characteristics of Silicone Rubber
Silicone rubber is a polymer elastomer with a main chain and side chains composed of silicon atoms and organic groups. The side groups are organic groups. Because of its large bond angle, large orientation freedom, and good flexibility, it has excellent low-temperature resistance. Because of its large bond energy (./), it has good high-temperature resistance []. Its glass transition temperature is low (~℃), its performance changes little near room temperature, and the structure of the silicon-oxygen bond makes its mechanical properties relatively stable in a wide temperature range (~℃)
2. Silicone rubber damping material
. Damping material
A material that converts solid mechanical vibration energy into heat energy and dissipates it. It is mainly used for vibration and noise control. The damping performance of a material can be measured according to its ability to dissipate vibration energy. The standard for evaluating the damping size is the damping coefficient. When missiles, launch vehicles and aircraft are flying, due to engine operation and aerodynamic noise, they will cause severe broadband random vibration and noise environment, and will also stimulate numerous resonance peaks in the structure and electronic control instrument system, causing fatigue failure of the structure. and dynamic instability, which reduces the accuracy of electronic control instruments and even causes failure. Statistics show that about one-third of rocket ground and flight test failures are related to vibration, and poor damping performance of structural materials is an important reason for such failures. In order to improve the damping performance of the structure, structural materials and damping materials can be combined into composite materials, that is, the structural materials bear the stress and the damping materials produce a damping effect to achieve the purpose of controlling vibration and reducing noise
