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 design 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 composites fan cases are summarized. Drawing on the recent research hotspots, new ideas and technologies for composite aero-engine structures are prospected.

Key words: aero engine, polymer composite, fan case, blade, containment design, multiscale analysis, Foreign Object Damage (FOD)
