THREE-LAYER HULL CONSTRUCTION Russian patent published in 2003 - IPC

FIELD: construction of hulls of ships, platforms and other vessels of metal and non-metal materials, applicable in shipbuilding, in other branches of transport machine building, and industrial engineering. SUBSTANCE: the construction consists of two bearing layer and a corrugated member; one of the bearing layers is made of glass plastic, the other - of metal, and an additional corrugated member of glass plastic is positioned between the layer of glass plastic and the metal corrugated member, and the cavities of the corrugated member are filled with porous material with a density of 0.05 to 0.15 kg/cu.cm. The bearing layer of metal and the corrugated member are joined by welding, and the bearing layer of glass plastic and the additional corrugated member of glass plastic to the main corrugated member of metal - by adhesive joint. When the offered three-layer hull construction of metal is used, the mass of the construction is reduced 40-57%, the damping characteristics are enhanced by 60 times, the noise level is reduced by 12-14 dB, and the thermal conductivity by 2.2 times, provided a high corrosion resistance. EFFECT: enhanced quality. 1 dwg, 2 tbl
