This paper deals with the analysis of mechatronic systems including piezoelectric materials used as sensors or actuators for stabilization and damping of mechanical vibration.
Therefore mechatronic systems including piezoelectric materials which are introduced into mechanical system and used as sensors or actuators for stabilization and damping of mechanical vibration are becoming increasingly popular.
It is indispensable to take into account geometrical and material parameters of all system components.

It was found that the fracture toughness of the nano-silica modified epoxies and the interlaminar fracture toughness of nano-silica modified CF/EP composites have been increased significantly (>50%), while the strength and modulus of the materials remain unchanged or slightly higher.
Some CT specimens in each group were post cured at 110 o C for one hour to further increase the cross-linking density of the materials.

Research on the properties of nanoparticles modified sodium silicate adhesive Xin-li Zhang1, a, Yi-qiang Wu1,b* and Yun-chu Hu1,c 1School of Materials Science and Engineering, Central South University of Forestry and Technology, Changsha, P.R.
Usually said silicate adhesive mainly refers to the reactive adhesive, which generally consists of the main binders, curing agents and skeleton materials.
Adhesive structure was analyzed to show interaction between Na2SiO3 and nano-materials, and the cured morphology and thermal properties were determined to support the quality improvement of Na2SiO3 adhesive by adding nano-materials.
Materials and Methods Materials. 3.0 modulus Na2SiO3 solutions were obtained from Shangyu Qiangsheng Chemical Co., Ltd.
