Processing and properties of C/Si–B–C–N fiber–reinforced ceramic matrix composites prepared by precursor impregnation and pyrolysis

The fabrication of C/Si–B–C–N fiber–reinforced ceramic matrix composites (FRCs) is reported. The processing basically involves three individual steps: (i) vacuum-assisted infiltration of a liquid two-component Si–B–C–N precursor into stacked woven carbon fiber fabrics, (ii) stepwise thermal cross-li...
