FIELD: manufacture of aircraft and ship structures. SUBSTANCE: the method involves placement of prepreg on the mould surface, matching of sealed technological pack, pressure test by creation of vacuum within 0.04 to 0.1 MPa at least for 2 hours and communication with the atmosphere after keeping of the space in vacuum at least for 30 min in the sealed technological pack. Subsequent moulding of multi-ply panel in the mould is carried out with heating up to the hardening temperature of polymeric binder. EFFECT: enhanced quality. 2 cl, 1 tbl
