Optimization of fiber orientation angle of a hybrid al/composite cardan shaft

Abstract

One important property of composite materials is the possibility to change their characteristics by changing the fiber orientation angle. By determining the optimal fiber orientation, the resistance to the torque effect, as well as the value of the critical rotational speed, can significantly be increased. In this paper, using the finite element method, we have examined the effects of fiber orientation angle on the basic static and dynamic characteristics of the shaft (twist angles, natural frequency). The shaft is composed of a combination of aluminum and composite layers of carbon and aramid fibers. In the conclusion section of the paper, optimal variants of the shaft have been identified.
