| Abstract: | Percolation theory of physics is applied to simulate, explain and analyze infiltration and pyrolysis process of C f/SiC composites by PIP. According to the models,the fabricating process of C f/SiC composites is optimized, density of the C f/SiC is condensed to 2.03 g/cm 3 from 1.75 g/cm 3,the strength reached 500 MPa from 300 MPa as a result,and mechanical properties could be obtained repeatedly. |
