Sponge absorbing materialIt is a material used in the fields of acoustics, electromagnetic waves, etc., which can absorb and reduce the propagation of waves. Sponge absorbing materials are widely used in fields such as aviation, aerospace, military, electronics, communication, and construction due to their excellent absorbing properties.
1、 Basic principles of sponge absorbing materials
The absorption principle of sponge absorbing materials is to absorb and consume wave energy through the small porous structure inside the material. When waves pass through sponge absorbing materials, their energy undergoes multiple reflections and scattering within the porous structure of the sponge, resulting in absorption. This absorption effect significantly improves the absorption performance of the material.
2、 Characteristics of Sponge Absorbing Materials
