An application of a rigid coupling is used to predict the limiting torque values based on the fibers properties, distribution, percentages, and orientation. The effects of the constituents weight percentages, and average fibers length on the composite tensile strength and modulus are studied using the Taguchi design of experiments method. A new approach of finite element analysis "FEA" is introduced to model the effect of the hybrid fibers random distribution and average fibers length along the volume of the matrix. The FEA model is applied on the tensile specimen and then on the power transmission coupling simulation. The Modeling technique is validated with the design of experiments. Different failure criteria are studied on the tensile specimen model and on a 3D loaded representative volume element with controlled fiber orientation and loading direction. Finally, the coupling suggested FEA modeling results are compared with the conventional isotropic simulation ER -
