Composite materials are materials, composed of two or more fundamental materials with different properties, when combined to get a material with different properties than that of individual constituents.
To overcome this problem, a new class of material presented, named as Functionally Graded Materials (FGMs).

The biopolymers material and biodegradable polymers is an alternative of product polymer in terms of new material because biopolymer materials would not involve the use of toxic or harmful components in their production besides that could degradation by a natural composting process [2].
The egg shell fragments were immersed in H2SO4 to remove impurity and interference materials.
Conclusions The results of this study gives an insight in understanding the structure of cellulose and chicken eggshell materials the result indicated the chicken eggshell consist of crystalline structural in phase of calcite while the cellulose have amorphous-crystalline structure.
