The invention relates to a forming technology of a composite wound pipe-shaped piece. The forming technology comprises the steps that first prepreg and second prepreg are wound to a mould core sequentially, and thus a pipe-shaped blank is obtained; the pipe-shaped blank, together with the mould core, is wrapped with an isolating membrane and ventilated felt, is arranged in a vacuum bag, is packaged and is arranged in an autoclave, the vacuum bag is vacuumized to allow the intensity of pressure in the vacuum bag to be between minus 100 kPa and minus 80 kPa, and then 0.8-1.1 MPa impressed pressure is applied to the pipe-shaped blank; the temperature in the autoclave rises to 90-110 DEG C, heat preservation and pressure maintaining are carried out for 6-14 min, then the impressed pressure isincreased to 1.8-2.1 MPa, and the heat preservation and the pressure maintaining are carried out for 45-75 min; the temperature in the autoclave rises to 160-175 DEG C, and the heat preservation and the pressure maintaining are carried out for 160-200 min; and cooling and pressure relief are carried out, and thus the composite wound pipe-shaped piece is obtained. By utilizing a stage-by-stage pressure applying process, around 1 MPa pressure is applied to the pipe-shaped blank before heating, so that the structure uniformity of a carbon cloth layer and a high silica cloth layer of the compositewound pipe-shaped piece is effectively ensured, loss of resin is reduced, and the defects are avoided; in addition, by utilizing a two-stage type heating mode, the heating time is shortened and the production efficiency is improved.
