This new form of materials with cement characteristics called geopolymer has been developed in recent years [4-5].
Geopolymer is addressed as a class of inorganic material obtained by reaction of an aluminosilicates source under strong alkaline conditions to increase the surface hydrolysis of the particle raw materials with a dissolution consisting of a certain amount of silica and alumina found in materials during polymerization by combined alkaline solution.
Materials and Method The present work intends to study the composites using epoxy resin enhanced with white clay based geopolymer.

In conditions of not changing the chair's surface elasticity, materials as well as surface shape, body pressure distribution can be changed by adjusting the height, the surface and backrest inclination to make a more comfortable chair.
The elastic supporting structure used in the chair designed by Shi, Zhenyu is a new type of glass fiber materials, being inconspicuous in memory than steel materials, so there is no fatigue basically.
Similarly, the cushion materials need to meet the ventilation and cooling performance, so it is commonly used polyurethane foam which easily emits water vapor from the surface quickly and has good ventilation property.

Logistics starts with the provision of raw materials and semi-finished goods for the manufacturing process, and finishes up with prysical distribution after sales of products.
During 1960s and 1970s, it was suggested that physical distribution function should be integrated with reproduction activities such as material sourcing and work-in-process inventory to form internal material flow management.
Integrated logistics has extended the concept beyond one enterprise to all enterprises involved in the whole supply chain, outsourcing the internally supplied materials and products to external suppliers.

The fly ash has a function of reducing rigidity of materials.
So, the resilient modulus of materials is decreasing also.
Visibly, adding fly ash can effectively enhance the flexural or split performance of the materials, it also can significantly improve the anti-cracking performance of the materials

The home appliances and cars are mainly composed by thin metal materials, but the recycling use has become one of the major problems [1].
A few years later, recycled steels may become the main raw materials of steel industry [2].
The regular pattern of the crack extension in the thin sheet metal materials is discussed for modeI, mode II and mixed-modeI/II loading conditions to find the sensitive fracture factors.

So it shows a strong nonlinear effect during the materials processing, which is more suitable for the high-precision microstructure fabricated [1-4].
In this paper, the interaction course and thermal-mechanical effect of laser processing materials between the matrerial and solution were analyzed.
After material was melted by the laser irradiating, high-temperature and high-pressure plasma also produce a recoil pressure on material in the expansion process.
