METHODS FOR INNER INSULATION OF MULTILAYER STRUCTURE WITH CORRUGATED CORE Russian patent published in 2019 - IPC E04C2/32 E04B1/76 B29C33/50 B29C44/18 

FIELD: plastic processing.

SUBSTANCE: invention relates to panels with corrugated core, in particular, to insulation of panels with corrugated core of components under pressure, such as high pressure vessels. Method for partial insulation of inner space of panel with pre-formed corrugated core, comprising first face sheet, a second face sheet spaced from the first face sheet, and bridges between the first and second face sheets, wherein said inner space is formed between the first face sheet, second face sheet and adjacent bridges, according to which divider is arranged in first part of inner space, placing membrane between separator and second part of inner space, insulation in the second part of the inner space is placed, the membrane is pressed to the separator, the membrane is cured and the separator is removed from the first part of the inner space.

EFFECT: disclosed are methods of inner insulation of multilayer structure with corrugated core.
