Introduction Tribology is one of the key points in industrial application of ceramic materials, and also the pivot of ceramic materials research.
Different TiB2 contents will significantly affect density of the material, and then the density directly affects the mechanical properties of materials.
Although the additive of TiB2 could improve the friction and wear properties, the high TiB2 content also affect the microstructure of materials and the surface of materials was easy to be broken, and is bad for the friction and wear properties.

Stress and System Energy in Erosion Process for Brittle Materials Xiaoqing Lian1,a, Xiumei Feng1,b, Mingxue Jiang1,c 1School of Material Science and Engineering, Xi’an University of Architecture and Technology,Xi’an ,Shanxi,710055, China alianxiaoqing0304@126.com, bfengxm1973@126.com, cmingxuejiang@163.com, Keywords: Solid Particle Erosion, Stress, System Energy, Impact Angle, Brittle Materials, Finite Element Method Abstract.
The latest prediction equations for erosion of ceramic materials were proposed by Y.I.Oka[7],which were verified in cases of metallic materials.
Although many studies on the solid particle erosion of brittle materials may be found[5-10], most of their targets were homogeneous materials.
They were heterogeneous brittle materials other than homogeneous brittle materials.
The erosion rate of brittle materials is at its maximum at normal incidence at room tempetature [5-10], which is different from ductile materials whose maximun erosion rate occurs at shallow impact angles.

Virgin thermoplastic materials are often chosen as the polymeric matrix in the current research due to their good mechanical properties and low processing temperature.

Silty clay was used as sub grade material.
Materials which are used to make fibers for reinforcement may be obtained from paper, metal, nylon, polyester and other materials having widely varied physical properties.
MATERIAL Composite materials consist of two parts.
