Abstract
A process is disclosed for infiltrating a liquid composition, such as a molten metal or thermoplastic or thermosetting polymer, into a porous solid material, such as a ceramic or porous metal, by contacting the porous material with the liquid composition at a first pressure and then increasing the pressure by at least the critical capillary pressure for the liquid composition/porous solid material system to effect infiltration. The infiltrated liquid composition may then be solidified inside the porous material, such as by cooling, to produce composite materials including ceramic-metal composites as well as ceramic-polymer, metal-polymer, and metal—metal composites.
