Introduction Drainage materials made of geosynthetic or geocomposite materials are increasingly used In hydrotechnical and civil engineering for drainage in earth dams, dykes, as well as in the basements of buildings and underground parking lots [1–5].
In this regard, it is necessary to create new drainage materials made of geocomposites with high reliability and water permeability.
Nowadays bentonite coverings [10] have been widely used, and earlier polymeric materials have found application for channel lining.
The bearing element of the «GP» geocomposite drainage material is a geogrid, which is made of propylene fibers of primary raw materials by extrusion method.

Experimental Design 1.Physical Features The experimental machine of RUM is of UMT-6 triaxial CNC ultrasonic wave, while the work piece materials is of ceramic glass( Zerodur), namely α (coefficient of thermal expansion of zero) of advanced glass material.
For boring and machining of ceramic materials as presented in Table 2, if the diameter is the same, the larger the rotation speed, power and feed rate are, the bigger the MRR is.

The development of eco-materials has become an important direction of materials science.
Using appropriate methods to evaluate the environmental impacts caused by materials production is important for eco-materials research.
The development of eco-materials, therefore, has become an important direction of materials science.
However, the development of eco-materials requires a tool to measure the environmental impacts related to the materials life cycle.
Upstream stage includes raw materials and fossil fuel mining.

This makes it possible to design surface layers of materials and control their properties.

A constitutive material law in framework of micromechanical modeling containing comprehensive constitutive equations for the constituent materials is adopted to model the non-linear behavior of the unidirectional layered materials.
The third assumption is a standard specification of time independent materials.

This paper aims to present preliminary researches on the influence of the shape and dimensions of composites materials on the stability of microwave heating.
Materials and Methods The research was focused on experimental research of thermal stability of cordierite material in microwave field.
The process can be improved in terms of heating time through optimizing the heating mechanism, but for large volumes of cordierite materials, the conditions will be changed.

Introduction The cement based materials is considered a nondurable material as it has low tensile and bending strength ,less limit strain and poor impact strength .It is difficult to suppress the growth of cracks and is apt to fractured.
Enormous economic losses caused by the sudden and uncontrollable damage of construction is avoidless .Therefore, cement based materials are limited as a kind of structural materials.
It has great significance to research the brucite-fiber-reinfored cement based composite materials as it could improve the performance of concrete.

This paper gives a way which utilizes the PTC (positive temperature coefficient) materials to preheat diesel in the injector in order to improve the cold start performance and emissions of engine.
Conclusions These data were obtained under still diesel, if PTC materials is settled in injector, before engine is started, the diesel in injector is still too,so fuel can be heated to 60℃ in several minutes.
