A multi-material composite carbon fiber sound-insulating floor for ships and its preparation method

Abstract

Composite carbon fiber and a method for preparing the sound insulation floor material of the present invention is a multi SHIP.The noise floor of the main load-bearing layer of carbon fiber composite layers, and soundproofing.Inlaid composite insulation layer is a silicone rubber hollow ball resin plate, inlaid Law the hollow resin spheres in a matrix and distributed, it may be desirable to increase or decrease acoustic insulation composite layer according to performance requirements and design thickness dimension.The number of layers of composite insulation may be changed according to design requirements, it can be designed of a strong, by the addition of materials of different density and quality of sound waves to achieve reduction of penetration effect, and interfacial carbon fiber composite material itself can absorb a lot of internal defects the vibration energy thus better absorption effect, the strength to be stronger than the traditional insulation materials, can be used as a floor or wall to partition ship out noise, reducing noise.Such multi-material mold Ship with sound insulation floor carbon fiber composite preparation method employed simply manufactured adjustable size, design flexibility, reduce the loss of material.

Description

technical field [0001] The invention relates to a multi-material composite carbon fiber sound-insulating floor for ships and a preparation method thereof, belonging to the application field of vibration and noise reduction technology. Background technique [0002] In the design of modern ships, people pay great attention to the quietness of ships. Ship quietness includes concealment and habitability (comfort). According to different types of ships, such as submarines, special emphasis is placed on concealment. The floors of ships are mostly made of iron or aluminum, and the noise generated by personnel activities is very large, which reduces the comfort of ships and the concealment of submarines. Being discovered in modern warfare often means being eliminated, so the design of surface ships has also begun to pay attention to concealment. Generally, ships mainly consider habitability (comfort), especially for tourist ships, more emphasis is placed on comfort. The quietnes...
