A preparation method of a high-strength and high-modulus inorganic sulfur/carbon fiber/polyethylene composite material belongs to the technical field of composite materials, and the specific scheme comprises the following steps: step 1, dispersing and uniformly mixing inorganic sulfur, carbon fiber and polyethylene resin to obtain a mixed material, and drying the mixed material; step 2, adding the dried mixed material into a forming mold, heating to 150-180 DEG C, keeping the temperature for 30-60 minutes, continuously heating to 200-230 DEG C, and keeping the temperature for 30-90 minutes; and step 3, after cooling and shaping, demolding to obtain the high-strength and high-modulus inorganic sulfur/carbon fiber/polyethylene composite material. According to the invention, inorganic sulfur is adopted to initiate a polyethylene crosslinking reaction effect and a carbon fiber reinforcement effect to synergistically improve the tensile property of polyethylene, and the tensile strength and the tensile modulus are
