The index to denote the combustibility of the textile material is limiting oxygen index that is the lowest volume percent of oxygen to maintain the materials burning in the air.The larger the limiting oxygen index the higher the percent of oxygen to maintain burning[1].This shows that the materials are difficult to burn.Tab.5 shows the limiting oxygen index of soybean protein fiber, wool and silk.

This might cause concrete materials degradation and reduce the mechanical performance of concrete seriously.
In order to enhance the durability of concrete materials in marine structures, many studies have been done recently [2-3].
The effects of freeze-thaw action on concrete materials The effects of freeze-thaw action on concrete materials mainly respond on the change of pores.
Therefore, the damage of elastic modulus of concrete materials is also inhomogeneous.

Two starting materials, pure PZT and doped PZT, were mixed to form four different compositions.
It comprises of a fluid-filled flexible tube connected at the ends to tubes of different flow impedance, which can be achieved by using tubes of different materials or geometries.
It was fabricated by sequential deposition of different PZT materials on the substrate followed by co-sintering.

Nanometer materials are solid materials which are constituted by minuteness crystalline grains whose feature dimensionality measurements are less than 100nm.
Nanometer material has excellent comprehensive performances due to its high surface activity, large specific surface area, and the subsize effect. [5-9] The author acquires Ni-P-PTFE- Al2O3 composite plating via adding to the Ni-P-PTFE alloy plating solution screened and preprocessed nanometer materials.

The piezoelectric ceramic used here is PZT 4 and the materials of the elastic body are brass, copper and SUS 304.
As a result of analysis depending on change in the material, the order of resonance frequency was determined according to the speed of sound, which has relation to Young’s modulus and density. [9] In case of SUS304, which has the highest resonance frequency among three materials, the highest output voltage was also shown because of high Young’s modulus.
Analysis of the output voltage depending on the applied Frequency When the materials of the elastic body were changed, the output voltage of generator using SUS304 was higher than the other generators because of high Young’s modulus.
