New materials refer to newly developed or developing structural materials with excellent properties and functional materials with special properties. Structural materials mainly use their mechanical properties such as strength, toughness, hardness, and elasticity. Such as new ceramic materials, amorphous alloys (metal glass) and so on. Functional materials mainly use their electrical, optical, acoustic, magnetic, and thermal functions and physical effects. In recent years, new materials researched and developed in the world mainly include new metal materials, fine ceramics and optical fibers.
