Structural materials for products can be divided into six groups namely, metals, ceramics, synthetic polymers, natural organic materials, natural inorganic materials and composites.
Renewable materials are materials which in a short time can be formed again in the nature and give no or very little impact to the environment.
The term renewable is typically used for organic materials.

But when mica paper is applied in the production binders and reinforcement materials are needed to enhance strength of mica paper [5].
However, binders and reinforcement materials can cut down insulation and temperature resistant of mica paper [6].
Experiment Experimental materials.
Mica paper can be made materials which can’t afford before.

Fig. 1 The schematic diagram of the structure of the interface scaffold Materials and Methods Preparation Preparation of CS Sponge 2g CS was dissolved in 100ml 1% (wt%) acetic acid solution and keep stirring until the CS has been totally dissolved to obtain 2%(wt) CS solution.
It’s similar to the relationship between crosslinking degree and pH because it is a positive correlation between compressive strength and crosslinking degree as normal polymer materials.
In(C), we can know that the material has a maximum compressive strength at 40min.

Material inventory management plays an increasingly important role in modern operations management within manufacturing enterprises.
First the material inventory styles are classified.
Connecting the characteristics of materials supply and the relationship between parts and production, a classification model based on materials attributes is put forward.
Decision process of parts inventory tactic Acknowledgments This work is supported by the Project which is supported by National Science & Technology Pillar Program in the Twelfth Five-Year Plan Period (2013BAF02B03).
