Abstract
Fiber reinforced polymer composites are of great significance for improving the thrust-to-weight ratio，fuel economy and environmental protection of aeroengines. This paper introduces the applications of polymer composites in aero-engine. The key challenges and technologies of composites-based fan case and fan blades including the de⁃ sign technology of preforms with complex shapes，high-precision manufacture technology of special-shaped composite structures，multi-scale and high-fidelity modeling method of composites，and the containment design criteria for com⁃ posites fan cases are summarized. Drawing on the recent research hotspots，new ideas and technologies for compos⁃ ite aero-engine structures are prospected.
