Problems solved by technology

At present, the three-dimensional network open-cell metal foam is mainly prepared by electrodeposition and vapor deposition. The prepared metal foam has a single structure and low material strength, resulting in poor mechanical properties and cannot be used alone as a structural material. Its scope of application and its influence on its performance

Abstract

The invention discloses a high-strength composite foam metal material and a preparation method thereof. High-strength composite foam metal is formed by compositing a foam metal layer and a reinforcinglayer, the mechanical performance of the foam metal is further enhanced on the premise that original excellent properties of the foam metal are not affected, the application field of the foam metal is broadened, the value of the foam metal material is further increased, besides, the preparation process is convenient and easy to operate, mass continuous production can be realized, and promotion and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of functional materials, in particular to a high-strength composite foam metal material and a preparation method thereof. Background technique [0002] Metal foam is a metal material with a sponge-like three-dimensional porous structure. It has become a new technology material with a wide range of applications. It integrates mechanical, thermal, electrical, acoustic and other properties, and has an irreplaceable important position in the field of materials. High porosity and high specific surface area are the structural characteristics and important characteristics of metal foam, and also the key properties that determine the obvious application advantages of metal foam in the fields of sound absorption and energy absorption, damping and noise reduction, electromagnetic shielding, filtration and separation. At present, the three-dimensional network open-cell metal foam is mainly prepared by electrodeposition...
