Polymer matrix composites (PMCs) have become one of the most important structure materials in the new generation of civil turbofan aeroengine due to their advantages of high specific strength, high specific stiffness, good designability, excellent vibration damping performance and feasible integrity fabrication. The PMCs application in aeroengine abroad based on fan blade, fan casing, acoustic liner and bushing was introduced firstly in this paper. The advantages of PMCs in structure optimization, economy and environmental friendliness were also illustrated. Moreover, new progress of PMCs including micro/nano material hybridization, 3D printing process and metamaterials in aeroengine was analyzed in details. Finally, some suggestions about PMCs application based on the relationship of "design-material-process-evaluation" were proposed for further development of civil turbofan aero engine in China.
