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

Abstract

The invention discloses a multi-material composite carbon fiber sound insulation floor for ships and a preparation method. The sound insulation floor is mainly composed of carbon fiber force bearing layers and sound insulation composite layers. The sound insulation composite layers are silicone rubber slabs inlaid with hollow resin spheres, the hollow resin spheres are distributed in a matrix according to the inlaying rule, and the number of the sound insulation composite layers can be increased or decreased according to the sound insulation effect requirement and the design thickness dimension demand. The number of the sound insulation composite layers can be changed according to the design requirement, so that the sound insulation floor has quite high designability; the effect of abating sound wave penetration is achieved by adding materials of different densities and masses, and a lot of vibration energy can be absorbed due to the interface defect in a carbon fiber composite, so that a better sound absorption effect is achieved, the strength is higher compared with that of a traditional sound insulation material, and the sound insulation floor is capable of serving as floors or wallboards of ships to insulate noise and reduce noise disturbance. According to the preparation method of the multi-material composite carbon fiber sound insulation floor for ships, an adopted mould is simple and easy to manufacture, the dimension is adjustable, flexible design can be achieved, and the loss of materials can be reduced.

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...
