Description
technical field [0001] The invention relates to the technical field of aluminum-based composite materials, in particular to a high-strength and high-plastic aluminum-based composite material and a preparation process thereof. Background technique [0002] Composite materials can be divided into three categories: polymer matrix composites (PMCs), metal matrix composites (MMCs), and ceramic matrix composites (CMCs). The matrix of metal matrix composites is mainly aluminum, nickel, magnesium, titanium and so on. Aluminum matrix composite material is a material with strong vitality that emerged in response to the needs of modern scientific development. It is composed of two or more materials with different properties through various technological means. Aluminum has many characteristics in the production of composite materials, such as light weight, low density, good plasticity, easy to master aluminum matrix composite technology, and easy processing. In addition, aluminum mat...
