Abstract

The invention relates to the field of bionic composite materials, and specifically relates to a metal-matrix bionic composite material reinforced by carbon nanomaterials, and a preparation method thereof. The composite material is composed of the carbon nanomaterials and metal, wherein in percentage by volume, the content of the carbon nanomaterials is 0.5%-40%, and the balance is metal; and the composite material microscopically has a bionic oriented structure, and is presented as that the carbon nanomaterials are arranged in a metal matrix in an oriented manner and in the form of sheet layers. According to the metal-matrix bionic composite material reinforced by the carbon nanomaterials, and the preparation method thereof, the metal-matrix bionic composite material reinforced by the carbon nanomaterials is prepared through the process flow of slurry preparation, freeze-casting, vacuum freeze-drying, organic matter removal and compaction treatment. The composite material has the excellent performance of light weight, high strength, wear resistance and the like, and reserves the function characteristics of electromagnetic shielding, electricity conduction, heat conduction and the like of matrix metal; and moreover, the structure and performance of the composite material can be effectively controlled by adjusting a preparation process, and therefore, the composite material has aconsiderable application prospect in the case of being used as a wave absorption material, a structure material and the like.

Description

technical field

[0001] The invention relates to the field of biomimetic composite materials, in particular to a metal-based biomimetic composite material reinforced with nano-carbon materials and a preparation method thereof, in particular to a microscopic oriented structure reinforced with graphene, carbon nanotubes or a combination of both Metal matrix biomimetic composite material and its preparation method. Background technique

[0002] Industrial development and social progress have continuously put forward higher and higher requirements for the mechanical properties and functions of metal materials, and at the same time put forward many restrictions on the development of materials in terms of light weight, energy saving, environmental protection, and recycling. It is of great significance to optimize the design and preparation of metal materials to achieve their excellent comprehensive mechanical properties such as strength-toughness matching and fatigue resistance, an...
