Abstract
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 PA1 (a) the inorganic fibers are inorganic fibers containing silicon, either titanium or zirconium, carbon and oxygen and being composed of PA2 (i) an amorphous material consisting substantially of Si, M, C and O where M represents Ti or Zr, or PA2 (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, where M is as defined and x is a number represented by 0<x<1, or PA2 (iii) a mixture of the amorphous material (i) and the aggregate (ii), PA1 (b) the composite material has an interlayer shear strength of at least about 9 kg/mm.sup.2, and PA1 (c) the composite material has a flexural impact value of at least about 250 kg-cm/cm.sup.2.
