The present disclosure provides a method for preparing an injection-molded fiber-reinforced composite article using a molding machine controlled by a controlling module connected to the molding machine. The method performs a molding simulation executed on the controlling module to generate a shear rate distribution of the composite molding resin in a simulating domain. Subsequently, the method generates an orientation distribution of the fibers in the composite molding resin executed on the controlling module by taking into consideration an effect of the shear rate on an inter-fiber interaction and/or an effect of the shear rate on reducing a response rate of the fibers. A controller then controls the molding machine with the molding condition to perform an actual molding for injecting the composite molding resin into at least a portion of the mold cavity.
