Introduction Functionally Graded Material (FGM) are totally different from the conventional material in such a way that in FGMs the structure and properties vary from one end of the casting to the other end whereas in conventional materials the structure and properties is assumed to be uniform over the entire specimen[1].
The centrifugal force progressively increases the volume fraction of the Si and Cu reinforcement within the liquid Al matrix along the length of the specimen, owing to the density difference between the three materials (ρAl =2700 Kg/m3 and ρSi =2300 Kg/m3, ρCu =8920 Kg/m3).

After entering the 1960s, with the application of new materials, new technology, new process, protective armor tanks on the battlefield the material, structure and type of continuous improvement, and make the tank armor ability have improved greatly.
This shows that even the same material, the structure of the material has important effect on its resistance to metal jet performance.
Use of smaller amounts of materials and the optimization of the structure of the form, improve the performance of metal jet penetration resistance, this work to continue to study and to deepen.

To date, biodegradable polymers, calcium phosphate ceramics, polymers derived from biological materials and various composites have been studied.
However, the scaffolds prepared from these materials generally do not have sufficient strength, and thus it is desirable to use a strong scaffold material for body tissue regeneration.
For preparation of stronger scaffold materials, metallic materials are currently being used.
This is because supply of oxygen and nutrients to the cells, and discharge of waste materials, are necessary during cell culture.
