Nano-ceramic materials and composite nano-sized solid materials in mechanical industries have a broad application prospect.
It is suitable for manufacturing micro-mechanical components by using a variety of metals and non-metallic materials.
One is the theory of micro-mechanism, the other is the material science of micro-mechanism, and another is the nano tribology [13].
The major research works on the material science of micro-mechanism are listed as follows: (1) Research on the materials of micro-structure and its physical properties; (2) Study on the mechanical analysis and the failure laws of micro-mechanical structure.

Interpenetrating Phase Composites (IPC) belong to a special category of composite materials, offering great potential in terms of material properties due to the continuous volume structure of both composite components.
Composite materials are categorized according to the type of their reinforcement, being particle, fibre or interpenetrating reinforcements.
Resonant frequency damping analysis are carried out in cooperation with RWTH Aachen University, Division of Materials Science and Engineering.
