摘　　要：针对国产T800级S与H型碳纤维对于三维机织复合材料风扇叶片的适用性开展试验研究,试验结果表明S型纤维具备更高的拉伸断裂强度,但其三维机织复合材料疲劳性能较差,适用于非疲劳高承载结构;而H型纤维三维机织复合材料的拉伸强度略低于S型纤维,但相同载荷条件下其疲劳寿命比S型纤维高108.91%,相比之下,H型纤维更适用于航空发动机风扇叶片。This paper focuses on the experimental investigation of the applicability of domestically produced T800S and T800H carbon fibers for 3D woven composite fan blades.The results show that T800S carbon fiber has a higher tensile strength than T800H,and that the tensile strength of T800H 3D woven composites is a bit lower than that of the corresponding T800S composites,while the fatigue life of T800H composites is 108.91%higher than that of T800S composites.As a result,T800H is more applicable for 3D woven composite fan blades.
