SiCp/Al composites

SiCp/Al is a kind of particle reinforced metal matrix composites, it is the third generation of electronic packaging materials. SiCp/Al are greatly interesting for a wide range of application owing to the ability to be tailored controlling the volume fraction of the reinforcement phase. These composites possess both structural and functional applications due to their superior properties such as high specific strength, high stiffness, high temperature resistance and reduced thermal expansion coefficient. Examples of applications are automobile, aeronautics, aerospace, and electronic packaging industris.
