FIBER SHEET MATERIAL FOR REINFORCING CIVIL ENGINEERING AND ARCHITECTURAL STRUCTURES
To provide a fiber sheet material for reinforcing civil engineering and architectural structures, showing excellent and stable high-level strength (Young's modulus) and final strain in a reinforcing method for civil engineering and architectural structures using a continuous fiber sheet, and showing excellent and stable reinforcing effect even when workability and productivity are required.SOLUTION: A fiber sheet material used for reinforcing civil engineering and architectural structures is composed of reinforcing cloth formed of high strength fiber and matrix resin. The high strength fiber is formed of polyparaphenylene terephthalamide fiber, and has a final strain of 3.0% or more along the reinforcing fiber orientation of the fiber sheet material, measured by a method described in JIS A1191.SELECTED DRAWING: Figure 1
【課題】連続繊維シートを用いた土木・建築物補強工法において、非常に良好で安定した高いレベルの強度（ヤング係数）と終局ひずみを示し、施工性・生産性が要求される場合においても、非常に良好で安定した補強効果を示す土木・建築物補強用繊維シート材を提供する。【解決手段】土木・建築構造物の補強に用いる、高強度繊維からなる補強用布帛とマトリックス樹脂とから構成されてなる補強用繊維シート材であって、前記高強度繊維はポリパラフェニレンテレフタルアミド繊維から構成され、かつ、ＪＩＳ Ａ１１９１に記載の方法により測定される、前記繊維シート材の補強繊維の配向に沿った終局ひずみが３．０％以上であることを特徴とする土木・建築物補強用繊維シート材。【選択図】図１
