The invention discloses a forming method of a carbon fiber pipe type piece. The forming of the carbon fiber pipe type piece comprises the following steps that S1, a heat-shrinkable plastic pipe layeris pre-treated, the inner surface and the outer surface of the heat-shrinkable plastic pipe layer are coated with a second isolation layer, and the surface of a mold is coated with a first isolation layer; S2, the carbon fiber material is immersed in a solution in advance, and then paving of the pre-immersed material is carried out; and S3, the pre-sucking process is carried out, under the condition of certain temperature and pressure, a certain amount of resin is sucked from carbon fiber material layer laminated blocks, so that the resin content of the carbon fiber material layer is controlled. According to the forming method, the heat-shrinkable plastic pipe layer is automatically shrunk under the high-temperature condition, meanwhile, the resin of the carbon fiber material layer is softened under the condition of high temperature, the carbon fiber material layer can be uniformly pressed by the shrinkage of the heat-shrinkable plastic pipe layer, so that the resin is flat, the effectof enabling the surface of the workpiece to be smooth is achieved, and the method is suitable for being widely popularized and used.
