飞机机体和部件的制造商正力图通过生产技术革新,降低利用复合材料的成本。据杜邦公司先进复合材料部主任介绍,降低加工成本是90年代要解决的问题,主要目标是用复合材料来代替金属材料以降低先进飞机的质量。诺斯罗普公司结构研究部主任说,如果机体材料的50％为复合材料,那么机身内结构,比如大梁、机架和底部大梁,必须由复合 Manufacturers of aircraft bodies and components are trying to reduce the cost of using composite materials through manufacturing innovations. According to DuPont advanced composite materials department director introduced to reduce the cost of processing is the 90’s to solve the problem, the main goal is to replace the metal composite materials to reduce the quality of advanced aircraft. The director of Northrop’s Structural Research department said that if 50% of the material in the body is composite, the fuselage structures, such as girders, racks and bottom girders, must be made of composite
