Research and Application of Functionally Gradient Materials

Functionally gradient materials are continuous in their physical and chemical properties, such as composition, texture, density and elastic modulus. This material is an advanced material with different functions. The current states and preparation methods of functionally gradient materials are reviewed. Applications of functionally graded materials in biological, chemical, aerospace and other fields are summarized, the development and research hot-points of functionally gradient materials are also prospected.
