FIELD: construction.SUBSTANCE: method for manufacturing hollow structures with inner walls includes manufacturing of workpiece by laying the prepreg layers of the upper and lower casings, cut by patterns, and frame forming, laying of workpiece into the mould, consisting of individual shaping parts, previous moulding of lined workpieces, extrusion by means of mandrels and sealed flexible bags placed inside the workpiece, and their removal from the item after extrusion. Laying of upper and lower construction panels is performed at the respective design formative parts of the mould, laying of inner walls and their preliminary moulding is carried out on the combined mandrel. Combined mandrel comprises rigid base and flexible edges. Individual workpieces with their shape-generating elements of equipment are collected into the integral design workpiece.EFFECT: improvement of quality of manufacturing design.3 cl, 3 dwg |
