STRUCTURAL LAMINATED INSULATING MATERIAL Russian patent published in 2000 - IPC

FIELD: structural laminated insulating materials that can be used as vibrated, sound- and heat- insulating materials in aircraft, ship, rocket, car and automobile building industries, in construction, elevator building, at manufacture of cars of tramways, air conduits and industrial fans, bodies of acoustic systems, radio receivers and TV sets. SUBSTANCE: the first modification of the invention offers a structural laminated insulating material comprising external flexible layers, at least one which is made of metal, and an intermediate viscoelastic layer featured by the fact that at least one of the external flexible layers is made of porous aluminium alloy with a porosity within 0.25 to 0.85. It may be made with pores measuring 1000 to 2000 microns. In accordance with the second modification of the invention, the structural laminated insulating material, having external flexible metal layers and an intermediate viscoelastic layer, is featured by the fact that the external flexible layers are made of porous aluminium alloy with a porosity within 0.25 to 0.85. EFFECT: enhanced sound, vibrated and heat insulation of material. 30 cl, 4 ex
