Inorganic cementing materials like Normal Portland Cement and Gypsum are often used in the form of fiber reinforced inorganic composite materials. The fiber reinforcement on inorganic matrices is aimed to improve the tensile strength and the toughness. To develop fiber reinforced inorganic composite materials and utilize them in practical use as building materials, manufacturing technics, fiber properties preferable to the dispersed phase in inorganic matrices and the reinforcing mechanism of the fiber reinforcement need to be researched. Then we carried out some experiments on fiber reinforced inorganic composite materials which consist of Normal Portland Cement or Gypsum as the Matrix phase and several fibers as the dispersed phase. The study on the fiber reinforcement is consist of three parts 5, 6 and 7. In this paper (part 5) the experimental results and the fiber properties which effectively work as the dispersed phase in inorganic matrices are explained and the foundermental fiber reinforcing mechanism on inorganic matrices under tensile stress is indicated. In part 6 a model explaining the tensile fracture mechanism of fiber reinforced inorganic composite materials is suggested and on the basis of this model the theoretical tensile strength of fiber reinforced inorganic composite materials is proposed. In part 7 the theoretical tensile strength is analysed and examined by comparing the experimental data.
