Zero pressure and permeation for preparation of carbon nanometer tube reinforced aluminum base composite material

The invention relates to a zero pressure and permeation for preparation of carbon nanometer tube reinforced aluminum base composite material which comprises, mixing nano carbon tube, magnesium powder and aluminium powder of a finite proportion through mechanical mode or ball mill blending in stainless steel tank with the existence of argon shield, loading into stainless steel crucible or moulding the ball milled powder into pre-cast members, placing into stainless steel crucible, heating pure aluminium or aluminium alloy in nitrogen atmosphere to 750-1000 deg. C, thermal insulation for a finite period of time, cooling down and discharging.
