Title:
SHEET MATERIAL
Document Type and Number:
WIPO Patent Application WO/2021/250891
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a sheet material which is capable of imparting a heat insulation property while ensuring air permeability. A sheet material 10 comprises: a sheet-like substrate 1 in which voids are distributed over the entire surface thereof; and a plurality of particulate members 2 which are made of a ceramic material which is formed hollow. The particulate members 2 are retained in the sheet-like substrate 1 without closing off the voids. Since the particulate members 2 are formed by a hollow ceramic material with relatively low heat conductivity, the heat insulation property of the sheet material 10 can be improved. Further, since the particulate members 2 are retained in the sheet-like substrate 1 without closing off the voids which are distributed over the entire surface of the sheet-like substrate 1, air permeability can be ensured across the entire surface of the sheet material 10.
