Abstract: A method for manufacturing carbon fiber reinforced aluminum composites is provided. Particularly, the method uses a stir casting process during a melting and casting process and reduces a contact angle of carbon against aluminum by inputting carbon fibers while supplying a current to liquid aluminum to induce the carbon fibers to be spontaneously and uniformly distributed in the liquid aluminum and inhibits a formation of an aluminum carbide (Al4C3) phase on an interface between the aluminum and the carbon fiber, thereby manufacturing carbon fiber reinforced aluminum composites having excellent electrical, thermal and mechanical characteristics.
