According to the basic theory of wind turbine blade, a SG6050 airfoil wind turbine blade model was built with a radius of one meter. Based on the bionic principle, the fiber angles varied from 5° to 90°. In order to reflect the symmetry of medial axis, negative angles were included corresponding to positive angles. The comparison between different plies was made through reliability theory based on the response surface method. The result shown that the fiber angles between 40° and 70° had higher reliability and 65° has the highest reliability.
