1. A method of flattening recycled carbon fiber material, the method comprising the steps of:
establishing two flat plates arranged at an upper and a lower position corresponding to each other, each of said two flat plates having an upper surface and a lower surface;
stacking a plurality of carbon fibers on the upper surface of the flat plate disposed at the lower position;
disposing a first ultrasonic unit along said upper surface of the flat plate disposed at the upper position and a second ultrasonic unit along said lower surface of said flat plate disposed at the lower position, wherein at least one ultrasonic probe is arranged on each of the first and second ultrasonic units;
wherein the at least one ultrasonic probe of the first ultrasonic unit and the at least one ultrasonic probe of said second ultrasonic unit cooperate with each other to emit vibrations transmitted through the carbon fibers stacked on the flat plate disposed at the lower position; and
breaking up the carbon fibers stacked on the flat plate disposed at the lower position into a loose and flattened state by said vibrations emitted by said at least one ultrasound probe of said first ultrasound unit and said at least one ultrasound probe of said second ultrasound unit.
