Problems solved by technology

Because it is made of metal wire, the heat capacity of the material itself is not high, and it cannot absorb a large amount of heat in a small temperature range. Although the vibration damping performance and environmental adaptability are excellent, it cannot meet the dual needs of vibration damping and thermal control at the same time.
[0004] At present, materials with both vibration reduction and heat storage are mainly realized by polymer materials, such as rubber, etc., filled with high latent heat materials inside, but limited by materials, they cannot work in high and low temperature, high vacuum, high pressure, nuclear radiation and other environments. short lifespan or not applicable at all

Abstract

The invention relates to damping and heat energy storage metal rubber and belongs to the field of composite materials. According to the metal rubber, elastic spiral pipes are filled with a phase change material firstly, the two ends of the spiral pipes are welded for sealing, then the spiral pipes are distributed according to the longitude and latitude rule, and compression molding is conducted. The metal rubber has the characteristics of variable damping and high multidirectional stiffness consistency and is particularly suitable for damping vibration attenuation in the violent vibration environment. The metal rubber also has the characteristics of being small in finished product size, low in weight, high in stability and resistant to aging, high temperature and low temperature, high vacuum, high pressure, space radiation, nuclear radiation, sunlight, ozone, corrosion and ionic bombardment, the metal rubber can be applied to the ground as well as spacecrafts, and the problems that an existing material with the damping and heat energy storage functions is poor in environment adaptability and short in working life, and the compatibility of damping and heat energy storage of the metal rubber is poor are solved.

Description

technical field [0001] The invention relates to a vibration-damping and heat-storing metal rubber, which belongs to the field of composite materials. Background technique [0002] Metal rubber is a homogeneous elastic porous substance, which has both the inherent characteristics of metal and the elasticity of rubber, and has the advantages of compact structure, small size, light weight, high stability, variable damping, and high consistency of multi-directional stiffness. characteristics. The vibration damping effect of metal rubber in the high-frequency resonance area is particularly obvious, and it can quickly convert a large amount of vibration energy into the elastic potential energy of the product, thereby effectively suppressing the resonance peak and ensuring the smooth operation of the damped part. Metal rubber also has the characteristics of anti-aging and strong environmental adaptability, and can withstand high and low temperature, high vacuum, high pressure, spa...
