Embodiment Construction

[0025] The overall technical idea of ​​the present invention is: based on the poor wettability between fiber and metal (wet angle > 90°), the selected carbon fiber does not need electroplating or electroless plating treatment, and the carbon fiber can meet the requirement of non-wetting with the base metal. According to the different requirements of the hole size, select carbon fibers with standard specifications of 1k, 3k, 24k, and 64k, and can also be combined or split for the combination of the above tows. The prefabricated body is made by hand or machine. The distribution of carbon fibers in the woven carbon fiber prefabricated body can be uniform or non-uniform; the size of the carbon fiber tow can be the same or different; the weaving direction of the carbon fiber can be vertical, horizontal, or between vertical and horizontal any angle. Solidify the prefabricated body and the molten metal in the cavity. The cavity mentioned can be a sand mold or a metal mold; the metho...

Abstract

The invention belongs to the field of material preparation and processing, and relates to a method for preparing a metal material with controllable long and deep through holes. The preparation method comprises the steps of selecting fibers, preparing a preform, and melting and pouring the metal material. The method has the advantage of solving the problems of incontrollable hole diameter, hole depth and distribution of the material with long and deep through holes, and can be used for preparing the metal material with controllable position, porosity, diameter and ratio of depth to diameter of long and deep through holes; the diameter of the long and deep through holes of the prepared material is 0.01-10mm, and the ratio of depth to diameter is 1-500. The preparation of the metal material with the long and deep through holes is simple in process and low in cost, and is easy for industrialization.

Description

technical field [0001] The invention relates to a method for preparing a metal porous material with controllable long and deep through holes, and belongs to the field of material preparation and processing. Background technique [0002] Porous metal material is a new type of engineering material with excellent physical properties and good mechanical properties developed rapidly in the world in the late 1980s. It has many excellent physical properties, such as small specific gravity, high stiffness, large specific surface, light weight Good shock performance, good noise reduction effect, high electromagnetic shielding performance, etc., make it widely used in some high-tech fields. For through-hole metal materials, it also has the advantages of high thermal conductivity, high gas permeability, and high heat exchange and heat dissipation capabilities. Metal foam can be used not only as a functional material in many occasions, but also as a structural material in some occasion...
