According to the requirements of aero-engine weight reduction design, based on the characteristics of light and high strength of TiB2 particle-reinforced aluminum matrix composites, the paper focuses on the stator vanes structure of a certain aero-engine low pressure compressor (LPC), finishes the job on design and machining of the specimen of particle-reinforced metal matrix composites, and studies on high cycle fatigue (HCF) test process. The results indicate that: (1) the design and manufacturing processes of specimens can achieve the goal of the HCF test; (2) the HCF strength of the specimens made from particle-reinforced metal-matrix composites is 246.30MPa, which can achieve the goals of the test; (3) the particle-reinforced metal-matrix composites used in this kind of stator vane specimen can meet the aero-engine design requirement for LPC stator vanes.
