Metal rubber honeycomb composite soft sandwich component preparation structure and method thereof

Abstract

The invention provides a metal rubber honeycomb composite soft sandwich component preparation structure and a method thereof. The metal rubber honeycomb composite soft sandwich component preparation structure includes a vacuum brazing furnace and a tooling fixture, the tooling fixture comprises a base and a support fixed to the base, a pressure plate is arranged above the base, and the support ismatched with an adjusting bolt in a threaded mode. The designed metal soft sandwich structure part is metal skin, the middle layer is a metal honeycomb core, metal rubber is clamped between the metalskin and the middle layer metal honeycomb core, under complex dynamic load, the elastic porous metal rubber mainly has the effect of damping vibration reduction, and a metal honeycomb core structure in the middle plays the role of impact resistance and energy absorption; and in addition, the metal soft sandwich structure further has the structural characteristics of light weight structure, sound absorption and thermal protection and the like. The preparation device is used for realizing the metallurgical and solid interface combination of an interface of the metal soft sandwich structure partunder the vacuum hot pressing brazing technology, and the comprehensive mechanical properties and environmental adaptability of the whole structure part are improved.

Description

technical field [0001] The invention relates to a preparation structure and method of a metal-rubber honeycomb composite soft sandwich member. Background technique [0002] With the development of industrial technologies such as aerospace, marine chemical industry and nuclear energy equipment, the requirements for the comprehensive performance of vibration-damping and sound-absorbing functional elastic structural materials are increasing day by day. Both the flexible metal rubber material and the rigid honeycomb structure have excellent performance in the field of vibration reduction and noise reduction. The present invention combines the characteristics of the two to improve the performance of vibration reduction and noise reduction. [0003] The main problems and defects of the existing vibration-damping and sound-absorbing materials mainly include: [0004] 1) The welding of the honeycomb core and the upper and lower skins of the traditional honeycomb structure mostly us...

AI Technical Summary

Problems solved by technology

[0007] The present invention improves the above problems, that is, the technical problem to be solved by the present invention is that the welding of the honeycomb core and the upper and lower skins of the honeycomb structure mostly adopts the adhesive technology, the acoustic performance and mechanical performance of the material are reduced, and other commonly used vibration damping methods Sound-absorbing materials are not suitable for extreme environments
