Abstract
With advancements in material technology,a surge in research and development has been witnessed for various high-performance materials,including metamaterials,each possessing unique functionalities.However,meeting the demands of high performance has rendered the application of a single material insufficient for achieving the required interface mechanical and functional integration properties.Functionally gradient composite materials have emerged as a pivotal breakthrough to address this issue.This paper introduces the application background,as well as the research and application status of functionally gradient composite materials in foreign countries.Furthermore,based on the prevalent issues in the domestic engineering field concerning functionally gradient composite materials,the challenges faced in their utilization are highlighted.When compared to international advanced levels,the development of functionally gradient composite materials in China encounters three major hurdles.Firstly,the preparation process remains relatively underdeveloped,impeding large-scale engineering applications.Secondly,due to the scarcity of performance evaluation methods,there is an urgent necessity to establish a coupled functional evaluation system.Thirdly,there is a scarcity of proprietary intellectual property rights pertaining to material design and simulation methods,coupled with the absence of a comprehensive database.Consequently,material design still largely relies on the experience of designers.Lastly,suggestions for the future application and development of functionally gradient composite materials are proposed.关键词
