Introduction Functionally graded materials (FGM) have widely used as structural components in aerospace, automotive engineering [1].
Therefore, structures where a substrate made of FGM is coupled with surface-bonded piezoelectric layers and using piezoelectric materials to realize structure vibration control in the engineering department has a broad application prospect.
Material Properties Generally speaking, most of the FGM are employed in high-temperature environments and many of the constituent materials may possess temperature-dependent properties.

Research on Fractal Characteristics of Cement-Based Materials by Nitrogen Adsorption Method TANG Minga,LI Jingqib School of Material Science and Engineering, Shenyang Jianzhu University, Shenyang, Liaoning, 110168, China atm24690309@126.com, blijingqi2469@126.com Keywords: cement-based materials; pore; fractal; nitrogen adsorption Abstract：In order to confirm the surface fractal dimension of the internal pore of complex porous materials by means of the FHH model and nitrogen adsorption method.
The complexity ,the particularity in macroscopic and microscopic structure ,the universality of use parts of the constituent materials, which determine the concrete materials science had to depend on the latest research results of various disciplines of cross to improve their own.
Concrete materials fractal theory can be used to be a new branch of materials scientific researching, as following the materials science, micromechanics, fracture mechanics, cement chemistry, rheological etc.
Pore structure characteristics is a important issue about cement-based materials science study.
From now on, in the cement concrete materials science study, pore characteristics and pore structure theory research become a focus.

Materials and Methods The materials investigated are virgin sugarcane pressmud.

Nowadays the polymer based composite materials which have high thermal conductivity attract more and more attentions.
Although the filler took fiber shape, the filled materials still have lower mechanical properties, because there is weak adhesion between the two materials.

At that quite large amount of fine fraction materials is generated, which are impossible to be used in a cupola furnace considering severe fractional makeup requirements for the charge materials.
Thus the reverse routing of combustion products and charge materials is arranged.
Then ground materials were mixed with the binding agents and water was added.
