【Abstract】 The new functional materials, which appeared in the 1980’s,have been widely used for many good properties.The optimum design and manufacture methods of functionally gradient materials have been discussed in the paper.According to the design idea of functionally gradient materials,two or more than two kinds of materials having different properties are chosen,and their properties such as composition,organization,structure and hollow are changed continually so as to destroy the interface and obtain a new functional material which can be applied in the environment of high temperature. The development of the new materials has broken through the field of high-temperature-resistant materials, and the new materials have been applied to many other fields such as sources of energy,chemical engineering,optics, electricity,biology and medical engineering.更多还原
