EXPERIMENTAL INVESTIGATION ON FATIGUE PROPERTIES OF CFRP MARINE PROPELLER BLADE

Abstract

Abstract: The blade of marine all-direction propeller was prepared from CFRP, which was designed and manufactured based on structure design of whole machine. The maximum design load is equivalent from pressure on blade surface under limited conditions by CFD method. Finally, fatigue test and residual strength test are completed on the specially designed device. The results show that the propeller blades don′t have any visible damage after fatigue test and the residual strength is far above limited strength. The structure design and manufacturing process of composite blade meet marine propeller′s requirements.

Key words: CFRP, propeller blade, fatigue test, residual strength

CLC Number:
