Problems solved by technology

But there are the following disadvantages: First, the preparation cost of fiber metal laminates is high, especially the use of titanium alloy fiber metal laminates; second, compared with the traditional sandwich structure, since the fiber metal laminates are made of titanium alloy or aluminum alloy, their thermal conductivity is very high , the fire performance of the prepared metal foam sandwich panel has not been improved, and its shock absorption performance and high temperature resistance performance have not been improved

Abstract

The invention relates to a metal-fiber foamed aluminum composite layer plate. The composite layer plate comprises at least one metal plate layer, at least one fiber layer and at least one foamed aluminum layer, wherein the fiber layer and the foamed aluminum layer are alternately bonded through a high-temperature-resistant polymer adhesive compound; as the outermost layer, the metal plate layer is bonded with the fiber layer through a high-hardness polymer adhesive compound. The invention further relates to a preparation method of the metal-fiber foamed aluminum composite layer plate. The preparation method mainly comprises the following steps: surface decontaminating treatment is performed on the metal plate layer and the foamed aluminum layer, treated surfaces are coated with the high-temperature-resistant polymer adhesive compound and the high-hardness polymer adhesive compound, and pressure curing treatment is performed after all the layers are bonded together. Compared with a metal foamed aluminium sandwich structure, the metal-fiber foamed aluminum composite layer plate disclosed by the invention has a better mechanical property, a better characteristic of shock absorption and a better performance of sound insulation, and also has a good performance resistant to high-speed impact, a good capability resistant to bending deformation, an extremely high performance of fire resistance, and low cost.
