Static tensile experiments were occupied on a composite fan blade according to the standardized experimental process to verify the mechanical properties required for the normal running of the blades. The test conditions covered the rated condition and the double overloaded condition of the blades. Experimental results have reflected that the composite blades meet the strength and fatigue lifetime requirements of normal operation. The formulation of the experimental procedure can provide references on the mechanical performance testing of the similar products. A setting method of composite property used on the CAE modeling of the complicated curving structures was proposed and a finite element model of the composite blade was established based on this method. The load-displacement response of the composite blade under the condition of the rated centrifugal force was calculated. Numerical results are in good agreement with experimental results, which indicates that the model is applicable in the analysis of the composite blades.
