The biocompatibility Today, the carbon materials have been the one of best biocompatibility materials.
Espically, the carbon materials maked by isothermal chemical vapor infiltration (ICVI) had represented as artificialy heart valve materials with the highest level, and had been also applied wildly to clinic.
The artificialy heart valve and eardrum repair materials also had been studied.
The resulits show that moderate rigidity, toughness, porous and toughness of this kind of materials is perfect artificialy bone repair materials.

According to the above analysis, the rise and fall of the material to the resonant vibration motivation working surface can be written as impact Among them:vm for when the material fell back to work surface of the vertical direction of speed; Δ t for materials and the impact of the work surface contact time; So the impact phase difference forΔφ = ω Δ t; The material fell back to work the speed of the surface, the type (5) get: Among them: x2d apex geological work for material surface of vertical velocity component; x2z for material fall back to work on the direction of the surface geological vertical velocity component.

Study on the tensile fracture characteristics of cars oil filter materials FENG Jian-yong1,2,a, ZHANG Jian-chun2, ZHANG Hua2 1.Donghua University Textile Institute,ShangHai,China 2.The Quartermaster Research Institute of General Logistics Department of the PLA,Beijing,China amydream1109@163.com Keywords:automobile oil filter, filter used material, tensile fracture, macro characteristic, microscopic characteristics Abstract.The oil filter materials are frequently subjected to abrading and all kinds of friction and making the materials suffered from damage,consequently,the property and service life of the filter materials is reduced.So the purpose of this thesis is to research the tensile performance of the automobile oil filter material and according to constant speed tensile test to measure the macro fracture characteristics,tensile property in the process of before and after tensile testing,tensile fracture form and the math expression.Then compared the breaking strength,breaking
elongation,elongation at break and breaking work of these ten oil filter materials.Hope that through the study on the tensile performance of the oil filter materials and summarizes the damage mechanism and tensile fracture form,in order to provides a new way to develop the new material.
Introduction There are many materials are used in the car oil filter,such as glass fiber filter paper,cotton wood pulp filter paper,the melting and spun-bonded polyester and polypropylene nonwoven filter material.The filter subject is matal deposits,solid particles and other impurities，meanwhile,the car engine oil filter material constantly exposed to brading,friction and other oil fluid force,so the oil filter materials often suffered from all kinds of problems and affected the service life and property.As a result,this paper mainly based on such a thought to research the wear fracture performance of car engine oil filter material and to see and to mater the wear performance.Simultaneously,it will provide a reliable basis for developing new filter material and trying to reduce wear fracture behavior,improving service life and reducing cost.

Finally, taking both characteristics of basalt fiber and the increase of cement-based materials costs into account, it can be drawn that top priority should be given to the basalt fiber rather than to other fibers for cement-based materials.
Therefore,it is completely feasible to make up high performance cement-based materials with fibers.
