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.

An Experimental Investigation on Transpiration Cooling for Supersonic Vehicle Nose Cone using Porous Material Lianjin Zhao1, a, Jia Lin1, b, Jianhua Wang1, c Jinlong Peng2, d, Dejun Qu2, e, and Lianzhong Chen2, f 1 University of Science and Technology of China, Hefei, 230027, Anhui, P.R.
In the previous experimental investigations, different gaseous coolant [1-4], liquid alcohol and water [5-10]was used as transpiration cooling media, and different porous materials, such as C/C, porous ceramic (91% Al2O3 and 9%SiO2) and metal net structure, were used as transpiration cooling matrixes.
These investigations concluded that the cooling effect of gaseous coolant is limited, but liquid coolant has a large potential to achieve a higher cooling capacity per unit mass due to its large latent heat released by liquid phase change, sintered metal materials have significant advantages in controllable permeability and better machining property.

The mosque's wooden materials total 313 pieces.This corresponds to the number of human bones.
Construction technology such as building materials that are effective (durable and sustainable) compared to before.
In the past, buildings were made with materials available nearby such as clay, stone, and wood.
However, currently, with technological developments, new materials are available that are more effective than before [59].
