The invention belongs to the technical field of composite material square cabins, and particularly discloses a composite material square cabin metal embedded part embedding method which comprises the steps that machining a metal embedded part into a design size, and cleaning the metal embedded part; cutting an aluminum honeycomb of which the size is the same as that of the metal embedded part; filling the aluminum honeycomb with a honeycomb filling glue, and forming grooves with the same length and width as the metal embedded part and the height being the sum of the height of the aluminum honeycomb and the height of the metal embedded part through cutting in a sandwich panel; placing the filled aluminum honeycomb in the groove with an adhesive film pasted inside; placing the metal embedded part on the aluminum honeycomb with the adhesive film attached to the surface; and laying an outer skin on the metal embedded part, and completing embedding of the metal embedded part. According to the invention, the bonding strength and fatigue resistance of a sandwich structure composite material are improved, and the bearing requirement of the embedded part is met, so that the service life of the sandwich structure composite material is prolonged.
