Problems solved by technology

For example, in the working environment with high humidity, frequent vibration, high or low temperature, the panel is easy to degumming, resulting in the failure of the load during use, which is far from the yield limit of the material used, and the mechanical properties are low. The structure is not stable, and the adhesive connection method will produce pollution during reproduction, which is not environmentally friendly

Abstract

The invention belongs to the technical field of honeycomb boards, and in particular relates to a non adhesive aluminum honeycomb board including an aluminum honeycomb core, a panel and a bottom plate, the honeycomb core is arranged between the panel and the bottom plate, a solder layer is compounded on the inner side surface, opposite to the honeycomb core, of the bottom plate, the surface of the solder layer is provided with a soldering aid, the upper end face and the lower end face of the honeycomb core are in correspondingly brazed connection with the panel and the inner side surface of the bottom plate, and the non adhesive aluminum honeycomb board improves the welding effect, has the advantages of stable structure, good mechanical properties and no pollution, and can better meet the requirements of environmental protection.

Description

technical field [0001] The invention belongs to the technical field of honeycomb panels, in particular to a glue-free aluminum 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, high or low temperature, the panel is easy to degumming, resulting in the failure of the load during use, which is far from the yield...
