PROBLEM TO BE SOLVED: To provide a flexible sheet that can be continuously used over a long term under high temperatures of 300 to 500°C, has high break strength and tear strength, and is excellent in acid resistance, alkali resistance and chemical resistance.SOLUTION: With a fabric having a yarn made of an aromatic heterocyclic high polymer fiber as a textile element as a base material, in a flexible composite on at least one surface of which an impregnated coating layer is formed of an aromatic heterocyclic high polymer, the aromatic heterocyclic high polymer that forms aromatic heterocyclic high polymer fiber may be the same kind or different kind from the aromatic heterocyclic high polymer that forms an impregnated coating layer, the fabric is a knitted fabric or a triaxial woven fabric with or without a gap, and, as needs arise, contains a polytetrafluoroethylene powder in an impregnation coating layer.SELECTED DRAWING: None
【課題】300〜500℃の高温での長時間連続使用が可能で、しかも高い破壊強さと引裂強度を有し、耐酸耐アルカリ耐薬品性にも優れたフレキシブルシートの提供。【解決手段】芳香族複素環高分子繊維からなる糸条を織編要素とする布帛を基材として、その少なくとも片面に芳香族複素環高分子による含浸被覆層が形成された可撓性複合体であって、芳香族複素環高分子繊維を形成する芳香族複素環高分子が、含浸被覆層を形成する芳香族複素環高分子と同一種であっても異種であってもよく、布帛は隙間を有する、または有さない編織物または三軸織物であり、必要に応じて含浸被覆層にポリテトラフルオロエチレン粉末を含むものとする。【選択図】なし
