宇航材料是航空、航天技术发展的物质基础,是材料科学与工程中最活跃、最前沿的一个领域。人们普遍认为,宇航材料的发展状况,在一定程度上反映了一个国家材料科学和基础工业的水平。本文从机体结构材料、发动机结构材料和功能材料三个方面说明宇航材料的现状和发展动向。 Aerospace materials are the material basis for the development of aerospace and aerospace technologies, and are the most active and cutting-edge field in materials science and engineering. It is generally believed that the development of aerospace materials, to a certain extent, reflects the level of a national material science and basic industries. This article illustrates the current situation and development trend of aerospace materials from three aspects of body structure materials, engine structural materials and functional materials.
