Through the experimental results, we concluded that the different welding quality of different materials and absorbing agent, and analyzed its material characteristic reasons.
The absorption can be adjusted by different filler materials or filler agents.

Hybrid materials are attractive for a large range of applications from medicine and biotechnology to telecommunication systems and fuel cells.
The polymeric materials were characterized by scanning electron microscope (SEM) and IR-spectroscopy.
Nowadays, proton conductive membrane materials for fuel cells are of great interest.

Using XRF and SEM analyses, it was found that both materials showed high crystalinity.
However, it requires a lot of time and man power especially when raw materials require for pilot and commercial scale processes.

However, just as material engineering science has been possessed of the vast advancements, such as anti- wearing and anti-stress and heat-resisting for material properties and their preparation technology levels were substantially raised up, thus, today material life was also substantially extended[3].
Furthermore，it was indeed pointed that these basic statistical analysis combined closely with surface analysis on the friction materials is the better mode, thus, the more profound analysis might be achieved especially in the effects of the accelerated life testing.
Moreover, in fact, the forthright and functional judging method was given in certain extent for the accelerated testing designed by this paper; (2) Through the life curve analysis, it was showed under three kinds of stresses that life law of the testing materials was primarily consistent according to life distribution.
