Abstract
Metal matrix composite is made by assembling pre-forms of porous reinforcing material with an array of separator plates in a die in a pressure vessel, and infiltrating molten metal matrix material. Pre-evacuation followed by pressurisation when the molten metal matrix material is introduced into the die aids the infiltration. Re-introduction of gas during initial heating prior to melting speeds the heat-up process.
