The fiber-reinforced hydraulic inorganic material to be used. ”The hydraulic inorganic material in the present invention can be used without particular limitation as long as it is an“ inorganic material that is hardened by hydration ”(hereinafter, simply referred to as an inorganic material). For example, various cements typified by so-called Portland cement, gypsum, calcium silicate and the like can be mentioned. Here, the hydraulic inorganic material of the present invention has a specific gravity of 1.
An inner layer having a specific gravity of less than 2 and a surface layer having a specific gravity of 1.2 or more are provided, and a surface layer having a specific gravity of 1.2 or more is provided on both surfaces or one surface of the inner layer with the internal layer interposed therebetween. Furthermore, the specific gravity of the inner layer is 1.0 or less, and the specific gravity of the surface layer is 1.4.
The above is preferable. Here, the surface layer needs to have the above-mentioned specific gravity except for the weight of the knitted fabric. The inner layer, as a method of making the specific gravity of the surface layer the specific gravity is not particularly limited, for example, for the surface layer, aggregate having a large specific gravity to the various cements described above,
For example, a method of mixing silica stone, silica sand, reducing the amount of water to be mixed, or using fine particles of silica stone, slag, silica fume, or the like to obtain a dense structure can be mentioned. On the other hand, as the inner layer, for example, pearlite, shirasu balloon, inorganic balloon hollow particles such as glass balloons, polystyrene beads, organic foam hollow particles such as polyvinylidene chloride beads are added, or the amount of water to be blended is extremely large. Examples include a method of increasing the number to make a rough structure. Furthermore, an inorganic material obtained by forming a so-called water-in-oil type (W / O type) emulsion from a hydraulic substance and a water-insoluble vinyl monomer such as styrene and curing the same is used to adjust the specific gravity by adjusting the amount of water to be mixed. Can be adjusted arbitrarily, and thus is preferably used. In the present invention, as described above, by setting the specific gravity of the surface layer to 1.2 or more, the compressive strength becomes sufficiently strong, the reinforcing effect by the knitted fabric arranged in the surface layer is sufficiently expressed, and the inner layer By making the specific gravity of less than 1.2, the weight can be reduced.

When the inner layer and the surface layer are separately manufactured in advance, the specific gravity of each test piece is measured. In the hydraulic inorganic material that has already been manufactured, the specific gravity of at least 10 test pieces cut from the outermost layer to a thickness of 1 mm was measured for the surface layer, and the fiber-reinforced water was used for the inner layer. At least 10 test pieces with a thickness of 1 mm are cut at a boundary of a half of the total thickness of the hard inorganic material, and the specific gravity thereof is measured. However, in the case where the knitted fabric exists within the range of 1 mm in thickness from the outermost layer, the same measurement as above is performed within the range of 1 mm in thickness from the boundary of the knitted fabric to the inside. In either case, the specific gravity is measured according to JIS A 5418.

The proportion of the hydraulic inorganic material is 30% or less in cross-sectional area. It is preferable that it is 20% or less. The cross-sectional area is a cross-sectional area when cut in a direction perpendicular to the laminating direction, and in the present invention, it is preferable that the cross-sectional area of at least 5 points is measured and that the surface layer has an average value of 30% or less. ..

Of these, carbon fibers that are inert to inorganic materials are most preferably used. Among them, the carbon fiber has an average diameter of 5 to 10 μm.
The monofilaments degree becomes a bundle of about 3,000 to 30,000 present, the tensile strength of 250 kg / mm 2 or more, a tensile modulus of 18000kg / mm 2 or more it is desirable. Further, it may have a slight twist in order to improve the convergence, may be bonded with a resin, or may be wound with other fibers. A knitted fabric is a woven or knitted fabric in which the reinforcing fibers are formed as warp yarns and weft yarns, and the reinforcing fibers are used in a direction in which reinforcement is strongly required, and inexpensive low-strength fibers are used in the other direction. It may be woven.
