1、 Overview of Aluminum Matrix Composites
The aluminum plate manufacturer introduces you to the knowledge of aluminum matrix composite materials:
1. Since the 1960s, carbon fiber, boron fiber, silicon carbide fiber, aramid fiber and other high-performance fibers have been developed. It is an important subject for the research and development of modern composite materials to prepare composite materials with them as reinforcement materials and metal as matrix.
2. Aluminum matrix composite materials and resin matrix composite materials, in addition to small density, high strength and modulus, small coefficient of linear expansion, and other characteristics, also have high temperature resistance, high thermal conductivity and conductivity, and are not flammable. They are suitable for aerospace industry, military industry, automobile industry and other civil industries.
2、 Classification of Aluminum Matrix Composites
Aluminum matrix composites can be divided into fiber-reinforced type (including short fiber), particle whisker reinforced type, layered type (alternating lamination type) and directional solidification eutectic type.
Fiber reinforced aluminum matrix composites have good comprehensive properties. However, the long fiber with high price, complex preparation process, high cost and limited development and application is mainly used in aerospace, military industry and a few civil industries.
The preparation process of particle reinforced aluminum matrix composite is simple, the price of particle reinforced material is not high, and the cost is low. The mechanical properties of particle reinforced aluminum matrix composite are not as good as that of fiber reinforced aluminum matrix composite, but compared with the matrix aluminum alloy, its hardness, modulus, wear resistance, fatigue performance, high temperature yield strength and thermal stability are greatly improved. Because the reinforcement is uniformly dispersed in the aluminum matrix and the composite is isotropic, the composite has great application potential. This material is a hot spot of research and development at home and abroad, and its practical application scope is expanding.
