短繊維補強セメント系複合材料の力学的性能に及ぼす材料因子の影響に関する基礎的研究

抄録

For the sake of finding the factors which influence the mechanical performance on short fiber reinforced cementitious composites, a parametric study was experimentally carried out. Nine parameters on fiber and four parameters on mortar matrix were varied. Then the experimental results on bend and compression tests were assessed for nine parameters concerning the mechanical performance indexes such as the maximum strength, deformability and several toughness indexes. Finally these results were analyzed by a multi regression analysis to formulate design criteria for the each mechanical performance index as a function of some selected parameters on fiber and mortar matrix.
