Advances in resin matrix composite fan blades for aircraft engines: A review

In the past few decades, the development of aircraft engines has targeted high bypass ratios and lightweight construction. The use of lighter and larger fan blades can facilitate the technical requirements of engine weight reduction with an increased bypass ratio, achieving improved engine operating efficiency and performance. The current literature has established that resin matrix composite fan blades (RMCFBs), as an alternative to traditional lightweight metal fan blades, exhibit high energy absorption efficiency and a stable response curve. This review assesses the latest research progress in the development and application of RMCFBs for aircraft engines. Firstly, the characteristics of different manufacturing processes are established with a classification of RMCFBs. Current application status of RMCFBs is discussed, evaluating the progress that has been made in specific systems. The pertinent experimental tests and numerical simulations applied to mechanical performance of RMCFBs at different levels are reviewed in detail, taking account of the defects in RMCFBs with consideration of non-destructive testing and the on-line monitoring technologies that have been employed. Finally, the current key research issues are identified, and future directions are proposed. This review can serve as a valuable reference that establishes current state-of-the-art in the design and development of RMCFBs for aircraft engine.
