The invention discloses a moulding method of a variable-density broadband wave-transparent quartz composite ceramic antenna housing body. The method comprises the following steps: according to dimension and quality request of the housing body, integrally weaving an outer material and an inner material to obtain an inner and outer housing body fabric; putting the housing body fabric in water to be cooked and soaking in acid liquor; then, putting the housing body fabric in an utensil filled with a silica sol for dipping and compounding; and finally machining a housing body blank to a required dimension to obtain the antenna housing body. According to the moulding method disclosed by the invention, the outer layer of the housing body fabric is woven by quartz fiber yarns, so that the volume percentage of the quartz fiber yarns is 40-45% while the inner layer of the housing body fabric is woven by hollow quartz fiber yarns, so that the volume percentage of the hollow quartz fiber yarns is 25-30%, therefore, the fiber volume percentages of the inner and outer layers of the housing body fabric are different. Meanwhile, the inner and outer layers are integrally attached and woven, the layering problem is avoided, and the housing body has relatively good structural strength is powerfully guaranteed as a result of relatively good strength of a reinforcement.
