Abstract

The invention discloses a pyramid-lattice metal sandwich plate and a preparation method of the pyramid-lattice metal sandwich plate, wherein a pyramid-lattice metal core body and a metal panel are adhered and compounded through epoxy glue to prepare an ultra-light porous material. The invention provides the preparation method of the pyramid-lattice metal sandwich plate adhered by the epoxy glue. Compared with the welding structure, the adhered pyramid-lattice metal sandwich plate has the advantages of being capable of reducing the manufacturing cost, reducing the residual stress during connection, improving corrosion and fatigue resistance and damping performance at the connection position, and effectively exerting performances of light weight, high ratio strength and high ratio rigidity, and can be widely applied to the fields such as communication and transportation and architectural decoration.

Description

technical field [0001] The invention relates to a metal interlayer board and a preparation method thereof, in particular to a pyramid lattice metal 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) and three-dimensional trusses. Structure (such as pyramid structure, tetrahedron structure). [0003] At present, common porous metal sandwich panels include truss structure sandwich panels and honeycomb aluminum sandwich panels. Among them, the fabrication of sandwich panels of trus...
