Preparation method of aluminum honeycomb core materials and honey comb plates

Abstract

The invention discloses a preparation method of aluminum honeycomb core materials and honey comb plates. According to the method, soft solder is used for preparing the aluminum honeycomb core materials and honey comb plates in a brazing manner. A product connector prepared by the invention can form a metallurgical structure, can be welded, and has light weight, strong strength, large rigidity, good stability, thermal and acoustical insulation and no pollution, so that the defect is overcome that a conventional adhesive type honey comb plate has an irregular honey comb core, and is greatly influenced by the property of adhesives; and the mechanical property of the honey comb plate is far higher than that of adhesive materials; moreover, the preparation process and the operation means are simpler, all performances are improved remarkably, and the preparation method is suitable for industrial production.

Description

technical field [0001] The invention relates to a preparation method of an aluminum honeycomb core material and a honeycomb panel. Background technique [0002] Due to a series of advantages such as light weight, high specific strength, high rigidity, good stability, heat and sound insulation, and no pollution, honeycomb panels have been widely used in aerospace, aircraft, trains, ships, construction and other fields. At present, the common honeycomb panels at home and abroad, whether it is the core material itself or the composite between the panel and the core material, are all glued, and the connection method is physical combination. Its strength, service life and allowable working environment are largely affected. Adhesive performance constraints. For example, in the working environment with high humidity, frequent vibration (including alternating positive and negative air pressure), high or low temperature, the panel is easy to degumming, resulting in the load being fa...

AI Technical Summary

Problems solved by technology

For example, in the working environment with high humidity, frequent vibration (including alternating positive and negative air pressure), high or low temperature, the panel is easy to degumming, resulting in the load being far less than the material used during use. Failure due to yield limit, lower mechanical properties

Solving the combination between the honeycomb core and the honeycomb core and the panel is the key to improving the mechanical properties of the honeycomb panel, but it is very limited to achieve a leap in the performance of the honeycomb panel only through the improvement and improvement of the adhesive performance
