Manufacturing method of open-cell foam metal filled composite material

Abstract

The invention provides a manufacturing method of an open-cell foam metal filled composite material. The method comprises the following steps: firstly, preparing an open-cell foam metal composite bodyblank for manufacturing a filled composite material, and carrying out linear cutting to obtain an open-cell foam metal complex core with required shape and size; secondly, manufacturing a metal wall filled with the composite material on the surface of the open-cell foam metal complex core, and finishing metallurgical bonding of the metal wall and an open-cell foam metal synchronously; thirdly, carrying out rough machining on an open-cell foam metal filled composite blank in order that the size of each machined part is slightly larger than the size of the required foam metal filled composite material, and carrying out melting removal operation on a compound in open-cell foam metal pores of the open-cell foam metal filled composite blank subjected to rough machining; and finally, performingfinish machining to obtain the open-cell foam metal filled composite material. According to the manufacturing method, the open-cell foam metal and the metal wall are metallurgically bonded, so that the open-cell foam metal filled composite material is resistant to high temperature and not prone to aging compared with an adhesive bonding method and the like.

Description

technical field [0001] The invention relates to the field of preparation of layered composite materials, in particular to a method for preparing open-cell foam metal-filled composite materials. Background technique [0002] As a new kind of porous composite material, metal foam filled composite material has many unique physical properties compared with traditional metal materials. Such as foamed aluminum sandwich panel, which has light weight, high specific stiffness and specific strength, better energy absorption, noise reduction and electromagnetic shielding properties; such as foamed copper filling tube, which has high thermal conductivity, heat transfer and Heat dissipation and other properties, so that when the metal foam filling tube with a through-hole structure is placed in flowing air or liquid, due to the high specific surface area and complex three-dimensional flow in the metal foam structure, heat can pass through the hole in the form of forced convection.
