Materials and Experimental Procedure The investigated magnesium sheets have the chemical composition as shown in Table 1.
Metallic materials exhibit the least formability, because fracture is caused the constriction of minor strains and thus lesser material is locally available for deformation.

However, PP materials currently used flammable, burning drops off when there will be melting, easily lead to fires.
Materials of the PP/IFR(70/33mass ratio)were blended by using two roll mill at 170℃.
From Fig. 6(A) we can find PP basically has no ability to generate carbon layer, belonging to flammable materials.
Table 2 shows the test results of tensile and impact properties of composite materials.

The misunderstanding of this cognition is that “green” is equal to minimize the use of raw materials in the progress of manufacture, considering the raw materials of the single product only, while ignoring the optimization of resource usage.
Green Design is to use law-priced raw materials.
Seen from the traditional one-way linear economy pattern “resource---product---pollutant discharge”, using plastic products instead of raw materials such as wood and paper, or immediate product made of natural materials, can truly reduce the stress level of natural raw materials supply to some extent.
As we have mentioned above, saving is not equal to lower cost simply through saving raw materials or using low-priced materials, and what we should do is to optimize the resources, which should not only refer to the single product and a certain individual, but should pay attention to the long-term usage of the resources in the whole society, so in the long run and on the whole, the resources are saved.
The endless repetitive productions of disposable and to-be disposable products do not only cause the huge waste of raw materials and energy, but also cause the waste of human resources.

For the orthotropic materials, the temperature change ΔT has a relationship with the change of principal stresses σT and σL in the directions of material symmetry [11,12] as follow ΔT= -Δ(KTσT+KLσL) 　　　　　　　　　　　　　　　　　　　 (1) where KT and KL are transverse and longitudinal thermo-elastic material coefficient.
