Carbon-Carbon composite materials are widely used as the surface thermal protection systems (TPS) of advanced high-speed air-craft and spacecraft.
The thin-walled structures with this kind of materials would exhibit large displacement response under high-level acoustic loads and possibly display buckling at elevated temperatures.

Introduction The rapid developments of frontier science continue to drive new requirements for materials’ rigidity-weight ratios, high strength-weight ratios and damage resistance to promote structure performances and reduce costs.
The biomaterials science, which refers to the structures, the properties, is aimed at researching the micro-structures, biological functions, structuring mechanisms of natural organic textures, at obtaining excellent bionic design methods and exploiting new bionic materials to benefit mankind.
Animals evolve many unique and talent natural biomaterials in recent 3.5 billion years to adapt the incredible complex environments and their obdurabilities, functional adaptations and self-healing abilities are inimitable compared with traditional materials [[] Wang Liduo, Sun Wenzhen, Liang Tongxiang, et al, Progress in bionic materials, Journal of Materials Engineering, 17, 2(1996) 325. ].
Especially, the hollow columns connect with each other in many ways, such as homodromous, orthogonal or spiral [[] Chen Bin, Peng Xianghe, Fan Jinghong, Fiber-reinforce characteristics of chafer cuticle and research on structure of branched fiber, Chinese Journal of Materials Research, 17, 6(2003) 630-636. ].
On the other hand, the mechanical performances of body materials affect the muscles performances inevitably.

Rice husk charcoal, a kind of new environmentally friendly biomass materials, which is made from rice husk under anaerobic combustion at 300˚C , has been increasingly applied to remedy some polluted sites.
In recent years, biochar was increasingly used as soil conditioner, carbon sequestration and new environmentally friendly biomass materials for remediation of some polluted sites with properties of strong adsorption and low cost [7, 8].
A potential wide prospect when biochar materials were used as wetland brusque has been shining upon reducing transport of pollutant and the bio-availability [9-12].
Materials and methods Rice husk charcoal.

Manufacturing of Composite and Hybrid Materials by Semi Solid Forming Dipl.
For this reason, the manufacturing of composite and hybrid materials is in focus of academic and industrial research.
These elements consist of specified combinations of different materials, or classes of materials, in the sense of reinforced lightweight metal matrices.
By means of such constitutive and structural material combinations, on the one hand, higher degrees of lightweight materials are obtained for structural elements and, on the other, intrinsic constitutive functions are produced, which visibly deviate from those of monolithic, metallic materials.
In addition further light-weight materials and filamentary reinforcing components will be investigated in this context.

Measurements show that deposited material has obvious delaminating structure and is corrosion resistant, whose components depend on those of the tool electrode material.
From polarity effect, the tool electrode should be anode, and discharge duration should decrease to get both more removal of tool electrode material and less removal of workpiece material, which is good for deposited material.

Conventional machining methods are unable to meet the challenges postured by the demand for economic machining of ultra-hard and high strength materials.
Electro discharge machining (EDM) is a promising technique with great potential for application to machining hard materials over conventional techniques.

Research on the Friction and Wear Test between Dental Prosthetic Materials and Natural Teeth LIU Hong-jie1,a, ZHENG Kan2,b, XIAO Xing-zhi3,c 1,2,3School of Mechanical Engineering Nanjing University of Science and Technology，Nanjing China 210094 alhjnjust@126.com, bzhengkan@mail.njust.edu.cn, cxxz.9202@163.com.
So it is important to investigate the friction and wear properties between denture prosthetic materials and nature teeth.
The findings highlighted that the wear of non-ceramic prosthetic materials in contact with enamel or dentin was similar.
The researches above were valuable to the study of friction and wear properties between dental prosthetic materials and natural teeth.

Therefore, these materials should be coated by conductive materials.
However, these materials are not widely applied because of the toxicity of Cobalt [1,2].
Other cathode materials that are believed to replace this material are phospho-olivine-based material.
The purpose of this heating aims to vaporize organic materials contained in the starting material.
