Mullite interlayer of C/Si-C-N composites fabricated by PIP

摘要：

Mullite interlayer of the carbon fiber reinforced Si-C-N matrix composite (C/Si-C-N) was fabricated by liquid precursor impregnation and pyrolysis (PIP). The mixture of aluminium sec-butoxide (A1OBu) and tetraethoxysilicate (TEOS) were used as starting materials. The monophase polymer gel used as mullite precursor could be formed from the mixture in the semi-closed air. A mullite interlayer with a thickness about 500nm is obtained at 1000oC- 1200oC for 2h. The fiber/interlayer bonds are tight. The carbon fibers are not damaged in the fabrication procedure.
