Li et al. [3] studied the failure condition of the stretch-bending process of the DP780 and AA2024-T351 materials.
The thickness and the strength of the materials are the crucial parameters for the development of damage development.

The commercial cordierite is almost manufactured from natural materials, such as bauxite, dolomite and talc et al [7-8].
Synthesis of cordierite from high-alumina fly ash could gain much more profit, comparing with synthesis of mullite, due to using the high-alumina fly ash and cheap talc powder instead of the industrial alumina or natural mineral materials.

Introduction The composite materials mean materials that are designed and consisted of more excellent properties than one individual material comparatively by combining more than two kinds of the material.
However, metal materials tend to stress the bone tissue due to the difference in rigidity.
