Problems solved by technology

At present, the preparation method of honeycomb panels is generally to vacuum-weld the stretched aluminum honeycomb core with the aluminum plates on both sides, but because there is air remaining between the multi-layer aluminum foils that make up the aluminum honeycomb core, the oxygen in the air will be on the aluminum foil and the aluminum foil. Oxidation of the connection between the honeycomb core affects the life of the honeycomb core

Abstract

The invention provides an aluminum honeycomb core with a filling material and a preparation method of an aluminum honeycomb plate. Through the formation of through holes and through grooves in the aluminum honeycomb core preparation process, residue air in the honeycomb core can be sufficiently discharged during the welding of the honeycomb core and aluminum plate. The oxidization of aluminum foils of the honeycomb core in the high-temperature welding process is avoided; meanwhile, fiber reinforced and brazing flux foaming resin materials are further filled into the honeycomb core; the supportis formed inside the honeycomb core; the external force collapse of the honeycomb core is avoided; the structure intensity of the honeycomb core is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a method for preparing an aluminum honeycomb core with filling materials and an aluminum honeycomb panel. Background technique [0002] The honeycomb structure has a large strength-to-weight ratio, can meet the requirements of high strength with a small cross-section, and can greatly reduce the self-weight of the structure itself. Therefore, the honeycomb structure has the advantages of good structural stability, impact resistance and cushioning performance. The honeycomb panel composed of double-layer aluminum plate sandwiching the honeycomb structure core has a series of advantages such as light weight, high specific strength, high rigidity, good stability, heat insulation, sound insulation and no pollution. Widely used in trains, ships, construction and other fields. At present, the preparation method of honeycomb panels is generally to vacuum-weld the stretched aluminum honeycomb c...
