Abstract
An inorganic fiber-reinforced metallic composite material comprising a matrix of a metal or its alloy and inorganic fibers as a reinforcing material, characterized in that PA0 (a) the inorganic fibers are inorganic fibers containing silicon, either titanium or zirconium, carbon and oxygen and being composed of PA1 (i) an amorphous material consisting substantially of Si, M, C and O, or PA1 (ii) an aggregate consisting substantially of ultrafine crystalline particles with a particle diameter of not more than 500 .ANG. of .beta.-SiC, MC, a solid solution of .beta.-SiC and MC and MC.sub.1-x, and amorphous SiO.sub.2 and MO.sub.2, provided that in the above formulae, M represents titanium or zirconium, and x is a number represented by 0<x<1, or PA1 (iii) a mixture of the amorphous material (i) and the aggregate (ii), PA0 (b) the inorganic fibers have an initial degradation speed of not more than about 0.3 kg/mm.sup.2.sec.sup.-1 and a tenacity reduction ratio of not more than about 30% during the production of the composite material, PA0 (c) the composite material has a short beam shear strength, measured in the monoaxially reinforced state, of at least about 8 kg/mm.sup.2, PA0 (d) the c…
