FIELD: construction engineering. SUBSTANCE: this can be used in manufacture of cowls, radioparent shelters of antenna arrangements, in aircraft industry, ship-building industry, and in ground surface construction. Multiple-layer panel is of high quality and easy to manufacture and this is achieved due to high strength of joining cellular filler of hexagonal structure and additional filler layers located symmetrically relative to middle surface of panel and serving for draining of moisture. Additional filler layers are made in the form of zigzag trapezoidal corrugation with flat sheet spread and this adds to technological easiness of production,. EFFECT: high efficiency. 1 cl, 4 dwg
