摘要
“一代飞机,一代材料”,材料是飞机制造的基础。在一百多年的世界航空史上,飞机发展的快慢,很大程度取决于材料。复合材料具有比强度和比模量高、疲劳性能和耐腐蚀性能好、密度小等特性,极大促进了民用飞机产业的发展。目前,高性能复合材料用量已经是衡量民机先进性的指标之一。本文重点阐述了欧美国家制定并实施的一系列航空复合材料研究计划及其取得的重要成果,介绍了国内航空复合材料发展历程,总结了复合材料在国内外民用飞机领域应用现状。基于未来国内民用飞机需求量,从原材料、结构件制造和工艺装备等方面,分析了复合材料应用降低飞机结构重量、减少运营成本和提升经济性的优势,讨论了复合材料应用于国产民用飞机的机遇与挑战。
“One generation of aircraft,one generation of materials”,materials are the foundation of aircraft manufacturing.In over a hundred years of world aviation history,the speed of aircraft development largely depends on materials.Composite materials have greatly promoted the development of the civil aircraft industry due to their high specific strength and modulus,good fatigue and corrosion resistance,and low density.At present,the amount of high-performance composites has become one of the important indicators to measure the progressiveness of civil aircraft.This article focuses on a series of aviation composite material research plans formulated and implemented by European and American countries,as well as the important achievements made.It introduces the development process of aviation composite materials in China.Summarized the current application status of composite materials in the field of civil aircraft both domestically and internationally.With the support of national policies and based on the future demand for domestic civil aircraft,this paper analyzes the advantages of composite material application in reducing aircraft structural weight,reducing operating costs,and improving economy from the aspects of raw materials,structural component manufacturing,and process equipment.The opportunities and challenges of composite material application in domestic civil aircraft are discussed.
