Light materials have become very important in most manufacturing sectors such as aviation and transportation industries. Much research has been done to improve the mechanical properties of lightweight materials, especially lightweight, high-performance aluminum foam composite materials. The mechanical properties of carbon fiber reinforced aluminum foam have the potential to depend on wetting and bonding of carbon fiber in the aluminum matrix. This paper provides a systematic design and procedure for developing aluminum foam composites using carbon fiber as a reinforcement and AlMg4Si8 alloy as a matrix (AMFC-aluminum matrix foam composite) were produced by powder metallurgy. Nickel coating on the carbon fiber surface is applied to control the reactivity of the interface of the fiber with aluminum during the manufacture of the composite to improve wettability between carbon fiber and aluminum. The effects of chemical oxidation and nickel coating on carbon fiber in the wettability of carbon fiber in aluminum foam were confirmed scanning electron microscopic analysis. Digital images produced by the imaging system are used with the MATLAB algorithm to determine the surface porosity and pore areaof aluminum foam in an efficient manner. The results can have important implications for the processing of carbon fiber reinforced aluminum foam composites and their mechanical properties.
