Preparation method of new aluminum-based silicon carbide material (AISIC) and application prospect of new SICP material

  With the continuous breakthroughs in the aerospace industry in recent years, the successful launch of many manned space projects is inseparable from the support of many new materials. Among them, the silicon carbide reinforced aluminum matrix composite material is used in Tianhe solar panels. How much do you know about this new material?

    Aluminum silicon carbide AlSiC (SICP/Al or Al/SiC, SiC/Al) is a particle-reinforced metal matrix composite material, which combines the characteristics of high specific strength, good plastic workability and low density of aluminum alloy matrix, and SiC particles It is a metal matrix composite material with excellent comprehensive properties due to its advantages of high hardness and low thermal expansion coefficient. Using Al alloy as the matrix, according to the design requirements, in a certain form, proportion and distribution state, using SiC particles as the reinforcement to form a multi-group phase composite material with obvious interfaces, which has comprehensive superior performance that a single metal does not have. Because of its light weight and high performance, it has broad application prospects in aerospace, automotive and other fields.
