    Abstract: PURPOSE:To prevent the leaning of fibrous bundles in a matrix and to improve the mechanical characteristics of a composite material by regulating either the warp or the woof to inorganic reinforcing fiber and providing the other with the compsn. same as that of the metal as the matrix. CONSTITUTION:In the reinforcing fibrous textile, either the warp or the woof is the bundles of inorganic reinforcing fiber and the other is the metallic wire having the compsn. same as that of the metal as the matrix. As the inorganic reinforcing fiber, the fiber composed of ceramics such as carbide, nitride, boride and oxide or of carbon can be used. The reinforcing fibrous textile is compounded with the matrix metal having the compsn. same as that of the metallic wire into the fiber reinforcing metallic composite material. In the obtd. composite material, the metallic wire is integrated into the matrix metal, by which there occurs a state where the inorganic reinforcing fiber is drawn and arranged toward one direction. In this way, since there is no winding caused by the crossing of each fiber bundle, the composite material having high bending strength, tensile strength, etc., can be obtd.

    Abstract: PURPOSE:To improve fracture toughness, compressive strength, etc., by kneading specific reinforcing surface-treated inorganic fibers with ceramic powder and calcining the resultant mixture. CONSTITUTION:Inorganic fibers consisting of (a) an amorphous substance consisting of Si, MC (M is Ti or Zr) and O, (b) beta-SiC, MC, a solid solution of the beta-SiC with MC and/or respective crystalline fine particles of MC1-x (x is 0-1) and an aggregate of amorphous SiO2 and MO2 or a mixed system of the components (a) with (b) are coated with a solution of at least component selected from polytitanocarbosilanes or polyzirconocarbosilanes, silane coupling agents, phenolic resins having 500-20000 average molecular weight and petroleum pitch in an organic solvent and dried to afford reinforcing surface-treated inorganic fibers (A) having a surface layer of 0.1-50mum thickness. The resultant component (A) is then kneaded with ceramic powder or an organic substance capable of providing ceramic by heating to be a matrix (B) and the obtained mixture is press formed under 50-5000kg/cm pressure and calcined at 600-2400 deg.C.

    Abstract: PURPOSE:To enhance strength by constituting an electromagnetic-waves transmitting material which is constituted of an amorphous inorganic fiber composed of silicon, carbon, oxygen and titanium or zirconium in specific ranges of percentage by weight, which has a specific resistivity value and which can transmit a specific range of microwaves selectively and by constituting a composite substance reinforced with the material. CONSTITUTION:An electromagnetic-waves transmitting material is constituted of an inorganic fiber composed substantially of Si, C, Ti or Zr, and O, and it has a resistivity of 15 -10 OMEGA.cm. The inorganic fiber contains 26-58wt.% Si, 25-62wt.% C, 0.5-30wt.% Ti or Zr, and 2-31wt.% O. The amorphous inorganic fiber constituting the electromagnetic-waves transmitting material transmits microwaves in a range of 500MHz-3000GHz selectively and its matrix is strengthened. If necessary, the electromagnetic-waves transmitting material can be used as a composite substance which uses a plastic or a ceramic as a matrix.

    Abstract: PURPOSE:To provide a fiber-reinforced metal which has overall excellent mechanical characteristics by consisting the same of continuous inorg. fibers consisting of Si, Ti or Zr, C and O and an Al alloy base material contg. a prescribed ratio of Ni and incorporating the needle-like phase of said alloy into said Al base material. CONSTITUTION:The continuous inorg. fibers which consist of an amorphous material substantially composed of Si, M, C and O, or solid soln. such as beta-SiC, MC (M is Ti or Zr) and/or respective ultrafine crystalline particles and aggregate, etc., consisting of amorphous SiO2 and MO2 and consist of Si, Ti, or Zr, C and O are prepd. Such continuous inorg. fibers and the Al alloy member contg. 0.5-6wt% Ni are combined by a casting method, more particularly high-pressure casting method and are solidified in a short period. The combined material is cooled from the direction orthogonal with the continuous fibers in the stage of such solidification, by which the fine needle-like crystalline material is crystallized in entanglement with said fibers in the direction perpendicular to the fibers among the continuous fibers, by which the excellent inter- layer shearing strength is imparted. As a result, the fiber-reinforced metal (FRM) having high strength is obtd.
