The present invention provides an electromagnetic wave-absorbing composite material and a manufacturing method therefor, the electromagnetic wave-absorbing composite material comprising: a polymer composite including a refractive index-adjusting material therein; and a plurality of conductive wires formed on at least one surface of the polymer composite, wherein electromagnetic waves reflected in a matching frequency (f) range derived through Mathematical Formulas 1 to 3 described in the present invention are 0.2 dB or less.

Electromagnetic wave-absorbing composite material comprising conductive wire and manufacturing method therefor

A heat insulation structure for corner parts of a liquefied natural gas (LNG) storage tank includes a secondary insulation wall arranged on an inner wall of a hull, a secondary sealing wall disposed on the secondary insulation wall, a primary insulation wall arranged on the secondary sealing wall, and a primary sealing wall disposed on the primary insulation wall. The heat insulation structure includes a corner assembly finishing an edge of the primary sealing wall at a corner part of the storage tank to complete sealing of the storage tank. The corner assembly includes an endcap sheet finishing each of four corners of the primary sealing wall provided to each surface of the storage tank to seal the four corners. The endcap sheet includes an endcap corrugation and an elongated corrugation extending in a direction perpendicular to a direction in which the endcap corrugation extends.
