<p>A hybrid fiber-reinforced plastic composite material comprising a matrix of a plastic and hybrid fibers consisting of inorganic fibers and at least one kind of fibers selected from the group consisting of carbon fibers, glass fibers, boron fibers, aramide fibers and silicon carbide fibers having a carbon core, wherein (a) the inorganic fibers are inorganic fibers containing silicon, either titanium or zirconium, carbon and oxygen and being composed of (i) an amorphous material consisting substantially of Si, M, C and O where M represents Ti or Zr, or (ii) an aggregate consisting substantially of ultrafine crystalline particles with a particle diameter of not more than 500 ANGSTROM of beta -SiC, MC, a solid solution of beta -SiC and MC and MC1-x, and amorphous SiO2 and MO2, where M is as defined and x is a number represented by 0<x<1, or (iii) a mixture of the amorphous material (i) and the aggregate (ii), (b) the composite material has an interlayer shear strength of at least about 9 kg/mm2, and (c) the composite material has a flexural impact value of at least about 250 kg-cm/cm2.</p> |
