The invention discloses a structural part forming method which comprises the following steps: a mold obtaining step: obtaining a mold of a structural part; an insulating layer laying step: laying insulating layer prepreg cloth at a position corresponding to the insulating layer in the mold, and carrying out vacuumizing treatment after laying the insulating layer prepreg cloth with the thickness of 1mm-3mm every time; a structural layer laying step: laying structural layer prepreg cloth at a position corresponding to the structural layer in the mold, laying a layer of structural layer prepreg cloth in a staggered manner after every 2-45 layers of structural layer prepreg cloth are laid, and carrying out vacuum pumping treatment after the structural layer prepreg cloth is laid in the staggered manner; a structural member curing step: heating, pressurizing and curing the structural layer prepreg and the insulating layer prepreg in the mold, and cooling to obtain a structural member; demolding, wherein the struct
