Abstract
In order to draw upon and refer to the experience in the development of composite fan blades abroad,the application progress of composite fan blades in commercial aviation engines is deeply studied,and the three development stages of composite fan blades from early exploration to mature application,and then to future prospects are discussed in detail.By introducing three core manufacturing technologies adopted by three overseas original equipment manufacturers(OEMs)of aviation engines—namely,the process of manual placement of prepregs combined with autoclave curing and molding,the 3D-woven structure with resin transfer molding(RTM),and the process of automated fiber placement of prepregs combined with autoclave curing and molding—this paper compares and analyzes the characteristics of these three preform manufacturing technologies.This paper comprehensively presents the production processes,manufacturing key points,and future development directions of composite fan blades.Facts show that composite fan blades have become a prominent feature of modern commercial aviation engines and are essential for the development of advanced aviation engines.Therefore,domestic research and development units should actively absorb the accumulated foreign experience in research and development,fully utilize the favorable opportunities provided by national development,and deeply explore and practice more material systems and process engineering details,aiming to achieve the early expansion of domestic applications of composite fan blades,thereby further enhancing the performance level of China's aviation engines.关键词
