FIELD: aircraft industry, shipbuilding and other industries.
SUBSTANCE: according to proposed method, outer shells and layer of filler with preset profile of corrugations are formed separately and then connected into other part. Corrugations of required profile are made by bending sheet blank to zigzag lines marked on filler development. Holes are made in said sheet blank in places of intersection of zigzag lines with diameter whose value is not less value of maximum radius of bending of sheet blank.
EFFECT: improved quality of panels with corrugated filler.
