民用航空器用新材料的现状与发展趋势北京理工大学珠海学院 2020 届本科生毕业设计(论文)民用航空器用新材料的现状与发展趋势摘 要对于民航业来讲，使用新型材料与否，这紧密联系着客机的制造成本、运营成本。本文从选材的角度、方法等等，对新型材料进行了研究。以碳纤维复合材料和钛合金的性能特点、应用现状、未来发展趋势等多方面阐述更换并运用新型航空材料的必要性，文章多出并同时体现了新型材料在当今主流客机上的应用现状，从而论证其观点。对于新型材料而言，文章内所体现的物理性质化学性质尤为重要。强有力的推动民用航空客机制造业的新型材料应用，这也可以为航空安全提供了保障，也同时新型材料的研究进步奠定了基础。关键词：选材；碳纤维复合材料；钛合金；复合材料I北京理工大学珠海学院 2020 届本科生毕业设计(论文)Current situation and development trend of new materials for civil aircraftAbstractFor the civil aviation industry, the useing model material or not. This is closely related to the cost of airlines and flight safety. In this paper, from the perspective of material selection, methods and so on, the new materials are studied. This paper expounds the necessity of replacing and using new aviation materials from the aspects of performance characteristics, application status and future development trend of carbon fiber composite materials and titanium alloy. The article presents the application status of new materials in the mainstream airliner at the same time, so as to demonstrate its viewpoint. For new materials, the physical and chemical properties embodied in this paper are particularly important. Strongly promote the application of new materials in the civil aviation airliner manufacturing industry, which can also provide a guarantee for aviation safety, but also lay the foundation for the research and progress of new materials.
