Abstract

Abstract: In this paper, the finite element analysis method is used to study the modeling of the compressor composite blade and the influence of the ply parameters on the composite blade. In the ANSYS platform, the ACP module is used to model the composite blade, and the accuracy of the composite blade modeling method is verified by comparing the modeling method of the traditional TC4 blade. The influence law of ply angle and ply thickness on the strength of composite blade was studied. The research result shows that with the increase of the ply angle, the maximum deformation of the composite blade first decreases and then increases, but the maximum equivalent stress of the blade gradually increases. Changes in ply thickness result in blade deformation and stress changes of no more than 5%. Therefore, the design emphasis should be placed on the ply angle when designing a composite blade.

Key words: composite blade, ply angle, ply thickness, deformation, stress
