Core material, vacuum double structure using the manufacturing method and the core material of the core material

摘要

PROBLEM TO BE SOLVED: To provide a core material extremely easy in handling, and a method of manufacturing the same.;SOLUTION: For solving the problem, a first core material 10 is constituted by dotting and arranging a large number of spherical members 12A-12G having high heat resistance, low heat conductivity and harder than base material sheets 11A-11G on an elastically deformable fibrous sheet having low heat conductivity or the base material sheets 11A-11G composed of deformable metallic foil for preventing radiation heat transfer.;COPYRIGHT: (C)2011,JPO&INPIT
