To provide a composite material which is variation-free in the mechanical strength occurring in the dispersion state of an inorganic filler, and has the mechanical strength exceedingly higher than theretofore, and also to provide a method of manufacturing the same.
Inorganic hollow particles and at least either cloth or felt of inorganic fibers are respectively laminated in a laminar form and are housed into a casting mold, and a molten metal is poured under pressurization into the casing mold and then cooled, by which the composite material including continuously a first composite material layer 1 containing at least either the cloth or the felt of the inorganic fibers and a second composite material layer 2 containing the inorganic hollow particles in a metal matrix and forming a single body as a whole is obtained.
