Abstract

The invention discloses a light multifunctional composite structure. The composite structure comprises a first outer surface plate, a second surface plate, a metal foam sandwich layer and a honeycomb sandwich layer, wherein the metal foam sandwich layer and the honeycomb sandwich layer are arranged between the first outer surface plate and the second surface plate, and the honeycomb sandwich layer is hexagonal aluminum honeycombs or square aluminum honeycombs. According to the sandwich structure through the composition of metal foams with the hexagonal aluminum honeycombs or the square aluminum honeycombs, the weight can be obviously reduced, and a plurality of functions such as load bearing, sound absorption, sound and heat insulation and shock resistance are provided.

Description

technical field [0001] The invention relates to a composite structure, in particular to a lightweight multifunctional composite structure. Background technique [0002] With the rapid development of high-tech, it is required to reduce manufacturing and operating costs as much as possible. People are not only pursuing the lightweight of materials, but also looking for advanced materials and structures that combine light weight with one or more other excellent properties. To meet the needs of different engineering applications, so as to realize the combination of multifunctional structures and engineering materials. In recent years, with the development of material preparation and forming processing technology, ultra-light porous metal materials are typical materials with multifunctional properties. This material integrates force, electricity, heat, sound and other properties, so it is widely used in aerospace, railway transportation, ships and other fields. [0003] The por...
