Friction and wear exist everywhere, resulting in substantial economic losses, so to improve the wear performance of materials is very necessary.
The research and application of ceramic material as friction components have received considerable attention in the field of tribology and new materials [6, 7].

To build SSPS, we must develop ultra lightweight materials and high efficiency energy conversion materials.
In order to achieve the object of SSPS, many dramatic advances are needed, such as development of ultra lightweight materials, high efficiency conversion system, and advanced functional materials.
At present, metal and polymer materials are used as space and aviation equipment material, like aluminum and titan.
