    摘要: A process of producing a ceramic matrix composite (CMC) is provided the steps of preparing a ceramic material having a plurality of pores as a CMC substrate; heating a metal material to be molten wherein the metal material has a melting point lower than the CMC substrate and has a high activity; adding the CMC substrate to the molten metal material so that the molten metal material enters the pores of the CMC substrate to occur chemical reactions; removing the CMC substrate filled with the molten metal material; and cooling the removed CMC substrate filled with the molten metal material to form a CMC having a plurality of metal grains. Plain strain fracture toughness (KIC) of typical ceramic S26 is 4.53 MPa m1/2. As a comparison, CMC has KIC of 21.11 MPa m1/2 about 466% of ceramic S26.
