Problems solved by technology

[0003] With the continuous improvement of people's quality of life, sound insulation and sound absorption treatment will be carried out in various places and interior decoration. With the continuous development of sound insulation and sound-absorbing materials, more and more types of sound-absorbing materials have emerged. Achieving a good sound-absorbing effect is usually very heavy, which brings certain difficulties and troubles to construction and decoration. At present, there is no good solution to improve the sound-absorbing effect or reduce the sound-absorbing effect. quality; therefore, a new lightweight sound-absorbing material is needed to solve this problem

Embodiment 1

[0039] can be based on image 3 , 4 As shown, the corresponding selection is made according to the carbon fiber layer 1. Taking the preparation of a hard sound-absorbing material composed of carbon fiber boards as an example, the mesh distribution of the rubber pads 3 is adjusted according to the carbon fiber layer 1, such as image 3 As shown, when the carbon fiber layer 1 is a carbon fiber board, the honeycomb mesh setting is adopted; the diameter of the composite fiber hollow pipeline is selected as d=10mm, the wall thickness s=2mm, and the inner down filling density ρ=80%, according to the following formula:

[0040]

[0041] Among them, n-number of arrangement, d-outer diameter of composite fiber hollow pipeline, ρ-down filling density, s-wall thickness of composite fiber hollow pipeline;

[0042] It is calculated that n=8.

[0043] like figure 1 As shown in the figure, an ultra-light and high-performance sound-absorbing material with a carbon fiber and down layered s...

Embodiment 2

[0057] This embodiment is basically the same as Embodiment 1, except that the gaps of the rubber pads are filled with down with a filling density of 30%.

Abstract

The invention discloses an ultra-light and high-performance sound-absorbing material with a carbon fiber and down layered structure. The cross section of the rubber pad is I-shaped, and the two ends of the rubber pad are used for bonding with the carbon fiber layer and the down sound-absorbing layer with adhesive, and the gap of the rubber pad is filled with down with a filling density of 30-50%; the down sound-absorbing layer The down sound-absorbing layer is composed of a composite fiber hollow pipeline group filled with down in a horizontal and vertical direction. The composite fiber hollow pipeline group is composed of a certain number of composite fiber hollow pipelines arranged side by side. The composite fiber hollow pipelines are bonded by adhesive. And each composite fiber hollow pipeline is filled with down with a filling density of 70-85%. The invention utilizes the laminated structure design of the carbon fiber layer and the down sound-absorbing layer, so that the sound-absorbing material has ultra-light weight and strong sound-absorbing effect at the same time.

Description

technical field [0001] The invention relates to the technical field of sound-absorbing materials, in particular to an ultra-light and high-performance sound-absorbing material with a laminated structure of carbon fiber and down. Background technique [0002] Noise is also a kind of sound, which originates from the vibration of objects. It causes the vibration of adjacent air to form sound waves, and spreads around in the air medium. When the sound is transmitted to the surface of the component material, part of the sound energy is reflected. Part of it penetrates the material, and another part is due to the vibration of the component material or the friction with the surrounding medium when the sound propagates in it, and the sound energy is converted into heat energy, and the sound energy is lost. In addition to the structure, thickness and surface characteristics of the material itself, it is also related to the incident direction and frequency of the sound. [0003] With...
