Embodiment 1

[0046] Embodiment 1: The die-casting process method of the foamed copper filling tube that is fully filled with the unsalted presolvation treatment open-cell foamed copper as the core

[0047] The specific implementation steps are as follows:

[0048] S1. Prepare an open-cell copper foam blank with required porosity and pore size for the fully filled copper foam filling tube. First, select high temperature resistant and water-soluble salt particles through the porosity and pore size, arrange them in the metal cavity and Compacting, and then pouring the molten metal liquid of metal copper, the required filling material of the fully filled copper foam filling pipe, for percolation casting, without salt precipitating treatment after cooling, and finally obtaining an open-cell foam copper billet without salt precipitating treatment.

[0049] S2. Carry out wire cutting on the unsalted presolventized open-cell foam copper billet selected in step S1 on a wire cutting machine, and obt...

Embodiment 2

[0054] Embodiment 2: take the open-cell foam copper-aluminum composite body as the core to make the die-casting process of the foam copper filling tube that fills completely

[0055] S1, prepare the open-cell copper foam blank of the required porosity and pore size of the foamed copper filling pipe of all filling, select the open-cell foam copper blank of required porosity and pore size as open-cell metal foam, because open-cell metal foam and The composite metals belong to different metals, and the melting point of the open-cell foam metal is higher than that of the composite metal. Metal aluminum is selected as the composite metal, so that the composite metal aluminum can be removed according to the melting point difference in subsequent operations. First, select the open-cell foamed copper billet with the required porosity and pore size, then pour the molten metal of the molten composite metal aluminum, pressurize so that the metal liquid of the molten composite metal alumin...

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. Emitt...
