ABSTRACT:
A method of producing a fiber-reinforced composite material in which a fiber body is mounted on mounting surfaces in a mold cavity, which mounting surfaces are in fluid communication with the outside of the mold through air relief passages. A molten matrix metal is poured into the mold cavity and then subjected to a high hydrostatic pressure so as to be filled into the fiber body while expelling the air from the fiber body to the outside of the mold through the air relief passages. The molten metal is thereafter filled into the air relief passages and solidifies immediately to seal the mold cavity from the ambient atmosphere whereby the molten matrix in the mold cavity is rapidly solidified under high pressure to form a fiber-reinforced composite material of high quality with inclusion of substantially reduced voids or cavities.
