Railway construction project materials and equipments management approaches in china classify the materials into two kinds: materials and equipments supplied by the part A and materials and equipments procured by their own.
To grasp the critical materials, the second step is selecting the key materials.
Supply logistics cost decreased about 2.46% of the value of materials in the project through materials supply plan based on materials requirement plan.

Due to their physical and chemical advantages when compared to classical industrial materials, composites are candidate materials of the future.
Composite materials are engineered materials made from the macroscopic combination of two or more different constituent materials under certain conditions and proportions that, individually, do not achieve the desired aim.

The mechanical properties of the materials are the common problems that the various materials must be involved in the practical applications.
How to utilize the characteristics of the mechanical performance of materials, how to prepare the composite materials with better overall performance and more additional features and how to meet the demands of industrial development for the composite materials are the propositions that the material science and the technology development always explore[1].
The emergence and the development of the prediction model of the mechanical properties of composite materials will be of great significance to the promotion of the theory of material science and the development of production.
