Problems solved by technology

However, the relative density of honeycomb aluminum made of aluminum foil on the market is lower than 0.05, that is, the mechanical properties are low, such as the out-of-plane compressive strength is lower than 5MPa, which cannot meet the demand in some occasions with high mechanical performance requirements.
Although the corrugated structure is relatively simple in manufacturing process and low in cost, its structural performance is much lower than that of honeycomb.

Abstract

The invention discloses a preparation method of a corrugation-aluminum honeycomb composite sandwich structural material, wherein a novel light porous sandwich compound structural material is obtained by compounding a corrugation sandwich structure and an aluminum honeycomb. The invention further provides a preparation method of the corrugation-aluminum honeycomb composite sandwich structure. A corrugation-aluminum honeycomb composite sandwich structural sandwich plate is of application prospect in the fields of communication and transportation, machinery manufacturing and military affairs. The prepared corrugation-aluminum honeycomb composite sandwich structural material provided by the invention can effectively reduce the weight of the structure, and exerts high strength, high rigidity, excellent damping performance and so on.

Description

technical field [0001] The invention relates to a composite interlayer material and a preparation method thereof, in particular to a corrugated-aluminum honeycomb composite interlayer board and a preparation method thereof. Background technique [0002] Ultralight porous metal materials are a class of novel multifunctional materials that have emerged with the rapid development of material preparation and machining technology in recent years. Its core has high porosity, and its microstructure can be divided into disordered and ordered according to the degree of regularity. The former includes closed-cell aluminum foam materials, while the latter includes two-dimensional lattice materials (such as corrugated structures, honeycomb structures) And three-dimensional truss structures (such as pyramid structures, tetrahedron structures). [0003] At present, the usual porous metal sandwich panels are mostly single structures such as honeycomb aluminum or corrugated. The honeycomb ...
