Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a flexible inorganic fibrous sewn heat-insulating structure suitable for heat insulating materials usable at >=1,300 deg.C such as surface protecting materials for a spaceplane or space shuttle, having highly heat-resisting property, thermal shock resistance and heat insulating properties and easily attachable to cabinets having complicated shapes, and to provide a method for producing the structure. SOLUTION: This flexible inorganic fibrous sewn heat-insulating structure is formed by entwining an inorganic fiber mixture of mullite fibers and silica fibers with an organic binder to form an inorganic fibrous board having enough strength for sewing without deformation, interposing the inorganic board between surface layer materials, stitching and integrating the resultant product with a heat resistant inorganic continuous fiber coated with a fluororesin, and then, burning the organic binder down.
