The invention relates to a metal lining-contained carbon fiber composite material body pipe and a prestress application method thereof. The body pipe comprises a metal lining, a metal tail pipe and a carbon fiber composite material layer; the metal lining is joined with the metal tail pipe; an annular groove is formed in the outer periphery of a cylinder body of the metal lining; and the carbon fiber composite material layer is corresponding wound in the annular groove, and has a tendency of annularly pressing the metal lining. The body pipe with the structure adopts the design mode of segmented assembly to relieve the weight of each section so as to bring convenience to carry; annular prestress is generated between the carbon fiber composite material layer and the metal lining, so that the two are tighter in contact; the carbon fiber composite material layer is suffered from annular tensile stress; and the metal lining is suffered from annular pressure stress, so that the stress conditions of the metal lining are improved.
