New materials refer to structural materials with excellent properties and functional materials with special properties that are newly developed or under development. Structural materials mainly use their strength, toughness, hardness, elasticity and other mechanical properties. Such as new ceramic materials, amorphous alloys (metallic glass), etc. Functional materials mainly utilize their electrical, optical, acoustic, magnetic, thermal and other functions and physical effects. In recent years, the research and development of new materials in the world are mainly new metal materials, fine ceramics and optical fiber and so on.
