功能梯度材料是一种新型复合材料，它的两侧由不同性能的材料组成，而中间部分的结构是以原子、分子级连续变化，从而消除了不同材料结合的性能不匹配因素。本文介绍了功能梯度材料的概念和开发背景，着重论述了功能梯度材料在材料设计、制备和性能评价方面的研究现状及其应用前景。
Functionally graded materials (FGMs) are new types of composites. They consist of materials with different properties on both sides. The structure of the middle part is continuously changed at the atomic and molecular levels, thus eliminating the performance mismatch between different materials. This paper introduces the concept and development background of FGM, and emphatically discusses the research status and application prospects of FGM in material design, preparation and performance evaluation.
