Recently, the microscopic nano-tribology[12] has received much attention with the continuous development of scientific research on nanometer materials.
Because the friction mechanism is unclear, the friction materials can only be chosen according to experiments so far.
Tomikawa have introduced results of comparison experiments on different friction materials, from which no significant advantage or disadvantage can be seen.
No unified standard has been defined for selection of friction materials for ultrasonic motors of different forms, and there is only some qualitative knowledge about this.
Therefore, the friction materials can only be selected according to experience.

In order to study the anti-aging properties of polypropylene / mica composite materials, the above polypropylene / mica composite materials were placed outside to study the influence of natural aging time on the anti-aging properties and to explore the natural aging mechanism of polypropylene / mica composites.
Natural aging research results show that:with the extension of the natural aging time the surface of materials will appear cracks and sheddings.
Preparation of composite materials.

Mechel and Vér (1992) stated that sound pressure brought about the sound; if the sound waves touch sound absorption materials during its delivery, the air molecule would dangle in the voids inside the material; energy would lose with the abrasion, so such material is with the function of sound absorption [4].
Experimental Materials. 7D three dimensional crimp hollow polyester fiber and 4D low-melting polyester fiber were mixed with the weight ratio at 7：3 to form the nonwoven.
The absorption of acoustical materials was tested using two-microphone impedance tube offered by Feng Chia University.
